hydrocodone and Substance-Related-Disorders

Recently, the U.S. Food and Drug Administration (FDA) approved Zohydro(®), an extended release formulation of the opioid analgesic hydrocodone that contains no acetaminophen. This approval was against the recommendation of the FDA's Expert Panel. Subsequently, both chronic pain advocates and anti-drug abuse advocates have steadfastly expressed their support of, or astonishment at this decision. Here, we review the pharmacokinetics, pharmacodynamics, safety and abuse liability of this hydrocodone formulation and how it relates to the Expert Panel's opinion and the FDA decision. We discuss the important issues, risk mitigation, potential use of abuse deterrents, and how the different viewpoints of the Expert Panel and FDA decision makers resulted in the approval and subsequent controversy.

Therapeutic opioid use and abuse coupled with the nonmedical use of other psychotherapeutic drugs has shown an explosive growth in recent years and has been a topic of great concern and controversy. Americans, constituting only 4.6% of the world's population, have been consuming 80% of the global opioid supply, and 99% of the global hydrocodone supply, as well as two-thirds of the world's illegal drugs. With the increasing therapeutic use of opioids, the supply and retail sales of opioids are mirrored by increasing abuse in patients receiving opioids, nonmedical use of other psychotherapeutic drugs (in this article the category of psychotherapeutics includes pain relievers, tranquilizers, stimulants, and sedatives, but does not include over-the-counter drugs), emergency department visits for prescription controlled drugs, exploding costs, increasing incidence of side effects, and unintentional deaths. However, all these ills of illicit drug use and opioid use, abuse, and non-medical use do not stop with adults. It has been shown that 80% of America's high school students, or 11 million teens, and 44% of middle school students, or 5 million teens, have personally witnessed, on the grounds of their schools, illegal drug use, illegal drug dealing, illegal drug possession, and other activities related to drug abuse. The results of the 2006 National Survey on Drug Use and Health showed that 7.0 million or 2.8% of all persons aged 12 or older had used prescription type psychotherapeutic drugs nonmedically in the past month, 16.387 million, or 6.6% of the population, had used in the past year, and 20.3%, or almost 49.8 million, had used prescription psychotherapeutic drugs nonmedically during their lifetime. Sadly, the initiates of psychotherapeutic drugs used for nonmedical purposes were highest for opioids. Therapeutic opioid use has increased substantially, specifically of Schedule II drugs. Apart from lack of effectiveness (except for short-term, acute pain) there are multiple adverse consequences including hormonal and immune system effects, abuse and addiction, tolerance, and hyperalgesia. Patients on long-term opioid use have been shown to increase the overall cost of healthcare, disability, rates of surgery, and late opioid use.

The purpose of this study was to evaluate the pharmacokinetics (PK) and 24-hour analgesic effectiveness of once-daily, single-entity, extended-release hydrocodone (HYD) with abuse-deterrent properties.. Four studies were included. Three open-label PK studies had the following designs: single-dose, 5-treatment, 4-period, crossover, dose-proportionality study; HYD 120 mg for 5 days (steady-state study 1); 2-treatment, 2-period, multiple-dose crossover study assessing the relative bioavailability of HYD 30 mg and hydrocodone 7.5 mg/ibuprofen 200 mg administered every 6 hours (steady-state study 2). A long-term, open-label study assessed the safety and effectiveness of HYD 20 to 120 mg in patients during a 52-week maintenance period.. Thirty-one, 25, and 22 healthy subjects completed the dose-proportionality study, steady-state study 1, and steady-state study 2, respectively, while 410 patients with moderate to severe chronic nonmalignant and non-neuropathic pain completed the long-term effectiveness study. Mean systemic exposure and peak plasma concentration were dose proportional after administration of single doses of HYD 20 to 120 mg. Pharmacokinetic profiles were comparable at day 1 and day 5 after administration of HYD 120 mg once daily. Once-daily HYD 30 mg was associated with lower-fluctuating plasma hydrocodone concentrations compared with immediate-release hydrocodone 7.5 mg/ibuprofen 200 mg administered every 6 hours. In the long-term study, pain control was consistent over the 24-hour dosing interval.. Once-daily HYD exhibits linear, dose-proportional PK properties and is associated with a lower variability in plasma hydrocodone concentrations when compared with an immediate-release hydrocodone combination product. Notably, analgesia provided by HYD is sustained during the 24-hour dosing interval. ClinicalTrials.gov identifier: NCT01400139 (Study 4).

The abuse potential of prescription opioids is well established. This study compared positive, subjective drug effects of single, equal doses of biphasic immediate release (IR)/extended release (ER) hydrocodone bitartrate (HB)/acetaminophen (acetyl-p-aminophenol [APAP]) 7.5/325 mg tablets versus IR HB/APAP 7.5/325-mg tablets and placebo.. Healthy adult recreational users of prescription opioids entered this randomized, double-blind, double-dummy, active- and placebo-controlled, seven-way crossover study. Participants received single, total doses of IR/ER HB/APAP 22.5/975 mg (intact; three active tablets) and 45/1950 mg (intact and crushed [encapsulated]; six active tablets), IR HB/APAP 22.5/975 mg (intact; three active tablets) and 45/1950 mg (intact and crushed [encapsulated]; six active tablets), and placebo. Peak subjective effects (E(max)); time to peak effects (TE(max)); and area under the drug-effect curves for drug liking, high, and good drug effects were measured using visual analog scales. Median values with 95% confidence interval (CI) were compared using analysis of variance.. Among completers (n = 52), IR/ER HB/APAP produced delayed and lower peak effects compared to equal doses of IR HB/APAP. Comparing intact tablets, the drug liking E(max) (median [95% CI]) was significantly lower for IR/ER HB/APAP 45/1950 mg (78.0 [73.0, 81.0]) than an equal dose of IR HB/APAP (89.5 [85.0, 93.0]; difference, -8.5 [-12.0, -6.0]; P < 0.001). Similar results were observed for intact IR/ER HB/APAP and IR HB/APAP 22.5/975 mg. Crushing IR/ER HB/APAP 45/1950 mg delayed these effects compared with an equal dose of crushed IR HB/APAP and intact IR/ER HB/APAP.. IR/ER HB/APAP resulted in lower subjective positive drug effects than an equal dose of IR HB/APAP. Crushing IR/ER HB/APAP also delayed the onset of subjective effects compared with intact IR/ER HB/APAP. These findings suggest that biphasic IR/ER HB/APAP has lower abuse potential than IR HB/APAP in single equal doses.. This Phase I clinical trial conducted in the USA was not registered.

Concern about abuse/dependence in chronic pain patients taking opioid analgesics may lead to undertreatment of pain, yet little is known about the prevalence of abuse/dependence in these patients and how it differs among analgesic agents. The objective of this study was to assess the prevalence of tramadol abuse compared to nonsteroidal anti-inflammatory drugs (NSAIDs) and hydrocodone-containing analgesics in patients with chronic noncancer pain (CNP). The study had three arms. The first arm consisted of subjects prescribed tramadol alone; the second of subjects randomized to either NSAIDs or tramadol; and the third of subjects randomized to hydrocodone or tramadol. Each investigator received two boxes of prescriptions randomized so that one in every four prescriptions was for tramadol. Upon deciding on the therapeutically appropriate arm, the physician selected the appropriate box, opened the next envelope and completed the enclosed prescription. After the initial randomization, physicians could prescribe whatever medication was therapeutically appropriate. A total of 11,352 subjects were enrolled. Up to nine interviews using a structured questionnaire were conducted over a 12-month period. An algorithm called the "Abuse Index" was developed to identify subjects who were abusing the drug. The primary components of the index were increasing dose without physician approval, use for purposes other than intended, inability to stop its use, and withdrawal. The percent of subjects who scored positive for abuse at least once during the 12-month follow-up were 2.5% for NSAIDs, 2.7% for tramadol, and 4.9% for hydrocodone. When more than one hit on the algorithm was used as a measure of persistence, abuse rates were 0.5% for NSAIDs, 0.7% for tramadol, and 1.2% for hydrocodone. Thus, the results of this study suggest that the prevalence of abuse/dependence over a 12-month period in a CNP population that was primarily female was equivalent for tramadol and NSAIDs, with both significantly less than the rate for hydrocodone.

The subjective, psychomotor, and physiological effects of prescription compounds containing the opioid hydrocodone have not been studied in a population of non-drug-abusing people who might be prescribed these compounds for cough or pain relief.. To characterize the effects of a hydrocodone combination product, Hycodan, which contains hydrocodone and a peripherally-acting anticholinergic, homatropine, in non-drug-abusing volunteers.. Eighteen volunteers participated in a crossover, double-blind study in which they received placebo; 5 mg hydrocodone/1.5 mg homatropine, 10 mg hydrocodone/3 mg homatropine, 20 mg hydrocodone/6 mg homatropine (all PO); 40 mg morphine (PO); and 2 mg lorazepam (PO). Measures were assessed before and for 300 min after drug administration. End-of-session and 24-h measures were taken to assess residual drug effects and overall subjects' assessment of the drug effects. RESULTS. Subjective effects of the hydrocodone/homatropine combination were dose-related, although the majority of statistically significant effects were limited to the highest dose combination tested. A combination of 20 mg hydrocodone/6 mg homatropine and morphine had a similar profile of subjective effects, which included both pleasant and unpleasant effects. Peak liking ratings were increased by 20 mg hydrocodone/6 mg homatropine and morphine, and trough ratings of liking (dislike) were lower in the 20 mg hydrocodone/6 mg homatropine condition, relative to the placebo condition. Post-session ratings of overall liking were not significant, either at the end of the session or 24 h later. Cognitive and psychomotor impairment were more marked with lorazepam than with hydrocodone/homatropine and morphine. Miosis and exophoria were increased in a dose-related manner by hydrocodone/homatropine.. Hycodan at the highest dose tested had effects similar to that of a prototypic mu agonist, morphine. Both drugs produced pleasant (including drug liking) as well as unpleasant subjective effects. Post-session ratings of overall liking and "want to take drug again" were not significant.

Enzymatic conversion of hydrocodone to hydromorphone is catalyzed by cytochrome P450 2D6, which is inactive in about 7% of Caucasians [poor metabolizers (PMs)] and can be inhibited by quinidine pretreatment in the remainder [extensive metabolizers (EMs)]. If hydromorphone, having a substantially higher mu-receptor affinity than hydrocodone, contributes importantly to the physiological and subjective effects of oral hydrocodone, then PMs should be less responsive to the same doses, and quinidine pretreatment should cause EMs to temporarily respond as PMs. Seventeen EMs and 8 PMs who previously responded positively to hydromorphone s.c. received placebo and hydrocodone (10 mg, 15 mg and 22.5 mg p.o.) and were retested with their favorite dose after placebo or quinidine (100 mg) pretreatment; physiological and subjective measures were collected at base line and four times after drug administration, and urine was collected for 8 hr. EMs and PMs were equally responsive to oral hydrocodone, and quinidine had no consistent effect on their responses, even though quinidine abolished the pre-existing metabolic differences in hydromorphone production, as measured in urine. These data suggest only a small role of hydromorphone in eliciting abuse-related responses to oral hydrocodone.

Herein we discuss the findings of a two-year wastewater-based drug use surveillance from September 2018 to August 2020 and present objective evidence on the impacts of the COVID-19 pandemic on drug use in a rural community. 24-h composite wastewater samples were collected twice each month from a university town in Northeastern United States and were analyzed for ten priority opioids and stimulants: morphine, codeine, hydrocodone, methadone, fentanyl cocaine, methamphetamine, amphetamine, 3,4-methylenedioxymethamphetamine (MDMA), and 3,4-methylenedioxy-N-ethylamphetamine (MDEA). All target drugs were detected at 100 % frequency in wastewater samples. On a mass basis, the average estimated per capita drug consumption were highest for cocaine, morphine, and amphetamine, and lowest for MDMA, MDEA, and hydrocodone. Furthermore, the estimated per capita consumption of fentanyl was higher than previous reports from rural and university settings in the U.S. Generally, drug consumption was higher during the spring semesters, with year-on-year semester increases also noted over the 2-y study period. Except for methadone and cocaine, the estimated average per capita consumption of drugs increased over the pandemic period, with the highest increase noted for MDMA (286 % increase compared to baseline, p = 0.016). Estimated average consumption of methadone and cocaine decreased slightly by 6 % and 7 %, respectively. These results demonstrate the utility and strength of wastewater-based approaches in capturing long-term and evolving trends in drug use within communities. Our study findings reflect the regionwide problem with opioid-related overdoses and increasing stimulant prescription rates. Our findings also provide objective data and insights for health policymakers on the effects of the pandemic period on community drug use in a rural U.S. town.

The concomitant use of prescription opioids and skeletal muscle relaxants has been associated with opioid overdose, but little data exist on the head-to-head safety of these drug combinations. The objective of this study was to compare the risk of opioid overdose among patients on long-term opioid therapy who concurrently initiate skeletal muscle relaxants.. We conducted an active comparator cohort study spanning 2000 to 2019 using healthcare utilization data from 4 US commercial and public insurance databases. Individuals were required to have at least 180 days of continuous enrollment and at least 90 days of continuous prescription opioid use immediately before and on the date of skeletal muscle relaxant initiation. Exposures were the concomitant use of prescription opioids and skeletal muscle relaxants, and the main outcome was the hazard ratio (HR) and bootstrapped 95% CI of opioid overdose resulting in an emergency department visit or hospitalization. The primary analysis quantified opioid overdose risk across 7 prescription opioid-skeletal muscle relaxant therapies and a negative control outcome (sepsis) to assess potential confounding by unmeasured illicit opioid use. Secondary analyses evaluated two-group and five-group comparisons in patients with similar baseline characteristics; individuals without previous recorded substance abuse; and subgroups stratified by baseline opioid dosage, benzodiazepine codispensing, and oxycodone or hydrocodone use.. Weighted HR of opioid overdose relative to cyclobenzaprine was 2.52 (95% CI 1.29-4.90) for baclofen; 1.64 (95% CI 0.81-3.34) for carisoprodol; 1.14 (95% CI 0.53-2.46) for chlorzoxazone/orphenadrine; 0.46 (95% CI 0.17-1.24) for metaxalone; 1.00 (95% CI 0.45-2.20) for methocarbamol; and 1.07 (95% CI 0.49-2.33) for tizanidine in the 30-day intention-to-treat analysis. Findings were similar in the as-treated analysis, 2-group and 5-group comparisons, and patients without previous recorded substance abuse. None of the therapies relative to cyclobenzaprine were associated with sepsis, and no subgroups indicated an increased risk of opioid overdose.. Concomitant use of prescription opioids and baclofen relative to cyclobenzaprine is associated with opioid overdose. Clinical interventions may focus on prescribing alternatives in the same drug class or providing access to opioid antagonists if treatment with both medications is necessary for pain management.

Between 2016 and 2017, the national mortality rate involving opioids continued its escalation; opioid deaths rose from 42,249 to 47,600, bringing the public health crisis to a new height. Considering that 69% of adults in the United States use online social media sites, a resource that builds a more complete understanding of prescription drug misuse and abuse could supplement traditional surveillance instruments. The Food and Drug Administration has identified 5 key risks and consequences of opioid drugs-misuse, abuse, addiction, overdose, and death. Identifying posts that discuss these key risks could lead to novel information that is not typically captured by traditional surveillance systems.. The goal of this study was to describe the trends of online posts (frequency over time) involving abuse, misuse, addiction, overdose, and death in the United States and to describe the types of websites that host these discussions. Internet posts that mentioned fentanyl, hydrocodone, oxycodone, or oxymorphone were examined.. Posts that did not refer to personal experiences were removed, after which 3.1 million posts remained. A stratified sample of 61,000 was selected. Unstructured data were classified into 5 key risks by manually coding for key outcomes of misuse, abuse, addiction, overdose, and death. Sampling probabilities of the coded posts were used to estimate the total post volume for each key risk.. Addiction and misuse were the two most commonly discussed key risks for hydrocodone, oxycodone, and oxymorphone. For fentanyl, overdose and death were the most discussed key risks. Fentanyl had the highest estimated number of misuse-, overdose-, and death-related mentions (41,808, 42,659, and 94,169, respectively). Oxycodone had the highest estimated number of abuse- and addiction-related mentions (3548 and 12,679, respectively). The estimated volume of online posts for fentanyl increased by more than 10-fold in late 2017 and 2018. The odds of discussing fentanyl overdose (odds ratios [OR] 4.32, 95% CI 2.43-7.66) and death (OR 5.05, 95% CI 3.10-8.21) were higher for social media, while the odds of discussing fentanyl abuse (OR 0.10, 95% CI 0.04-0.22) and addiction (OR 0.24, 95% CI 0.15-0.38) were higher for blogs and forums.. Of the 5 FDA-defined key risks, fentanyl overdose and death has dominated discussion in recent years, while discussion of oxycodone, hydrocodone, and oxymorphone has decreased. As drug-related deaths continue to increase, an understanding of the motivations, circumstances, and consequences of drug abuse would assist in developing policy responses. Furthermore, content was notably different based on media origin, and studies that exclusively use either social media sites (such as Twitter) or blogs and forums could miss important content. This study sets out sustainable, ongoing methodology for surveilling internet postings regarding these drugs.

The opioid overdose crisis is especially pronounced in Maine. The Diversion Alert Program (DAP) was developed to combat illicit drug use and prescription drug diversion by facilitating communication between law enforcement and health care providers with the goal of limiting drug-related harms and criminal behaviors. Our objectives in this report were to analyze 2014-2017 DAP for: (1) trends in drug arrests and, (2) differences in arrests by offense, demographics (sex and age) and by region.. Drug arrests (N=8193, 31.3% female, age=33.1±9.9) reported to the DAP were examined by year, demographics, and location.. The most common substances of the 10,064 unique charges reported were heroin (N=2203, 21.9%), crack/cocaine (N=945, 16.8%), buprenorphine (N=812, 8.1%), and oxycodone (N=747, 7.4%). While the overall number of arrests reported to the DAP declined in 2017, the proportion of arrests involving opioids (heroin, buprenorphine, or fentanyl) and stimulants (cocaine/crack cocaine, or methamphetamine), increased (p<.05). Women had significantly increased involvement in arrests involving sedatives and miscellaneous pharmaceuticals (e.g. gabapentin) while men had an elevation in stimulant arrests. Heroin accounted for a lower percentage of arrests among individuals age >60 (6.6%) relative to young-adults (18-29, 22.3%, p<.0001). Older-adults had significantly more arrests than younger-adults for oxycodone, hydrocodone, and marijuana.. Heroin had the most arrests from 2014 to 2017. Buprenorphine, fentanyl and crack/cocaine arrests increased appreciably suggesting that improved treatment is needed to prevent further nonmedical use and overdoses. The Diversion Alert Program provided a unique data source for research, a harm-reduction tool for health care providers, and an informational resource for law enforcement.

The prescription drug epidemic in the United States has gained attention in recent years. Vicodin, along with its generic version, is the country's mostly widely prescribed pain reliever, and it contains a narcotic component that can lead to physical and chemical dependency. The majority of Vicodin abusers were first introduced via prescription, unlike other drugs which are often experienced for the first time due to experimentation. Most abusers report obtaining their supply from a prescription, either their own or someone else's. Although the problem with prescription drug abuse is well known, there is no standard method of addressing the problem. To better understand how to do this, we develop and analyze a mathematical model of Vicodin use and abuse, considering only those patients who were initially prescribed the drug. Through global sensitivity analysis, we show that focusing efforts on abuse prevention rather than treatment has greater success at reducing the population of Vicodin abusers. Our results demonstrate that relying solely on rehabilitation and other treatment programs is not enough to combat the prescription drug problem in the United States. We anticipate that implementing preventative measures in both prescribers and patients will reduce the number of Vicodin abusers.

Heroin and fentanyl are the overwhelming and increasing cause of opioid deaths in Milwaukee County, Wisconsin. We reviewed all drug and opioid deaths from 2013 to 2017 to delineate the specific opioid drugs involved and changes in their incidence. From 2013 to 2017, 980 deaths were due to opioids, rising from 184 in 2013 to 337 in 2017. In 2017, opioid deaths exceeded combined non-natural deaths from homicide and suicide. Illicit heroin and fentanyl/analogs caused 84% of opioid deaths and 80% of drug deaths, with no increase in deaths due to oral prescription drugs such as oxycodone and hydrocodone. Any approach to decreasing this dramatic increase in opioid deaths should first focus on interdicting the supply and cheap availability of these illicit opioids. Fentanyl and its analogs represent the most deadly opioids and the greatest threat to human life in our population.

Opioids are widely used after orthopaedic procedures. Nonmedical opioid use is a growing public health issue.. An anonymous online survey was distributed by e-mail to the orthopaedic societies of all 50 states and several large private practices to assess practicing orthopaedic surgeons' opioid prescribing practices.. A total of 555 orthopaedic surgeons practicing in 37 states responded. The most commonly prescribed opioid for both teenagers and adults was hydrocodone/acetaminophen. Of note, 42.3% reported that a patient they have prescribed opioids for developed an opioid dependency, whereas 35.3% do not believe that opioid use is a problem in their practice. Of note, 30.3% reported prescribing refills, and factors significantly associated with increased prescribing of refills included a greater number of years in practice (P < 0.001) and practicing in a suburban rather than an urban or rural environment (P = 0.03).. Orthopaedic surgeons rarely prescribe any refills, tend to prescribe less opioids to teenagers than adults, and prescribe fairly uniformly for patients who are treated nonsurgically or undergo minor or arthroscopic surgery. They exhibit considerable variation in prescribing for fractures and major procedures.

In 2013, the Advisory Committee of the Food and Drug Administration determined hydrocodone combination medications (HCMs) needed tighter regulation due to high abuse potential; they recommended upscheduling HCMs from Schedule III to II. The purpose of this study was to examine the effect of upscheduling of HCMs on pain management practices of advanced practiced registered nurses (APRNs) in Oklahoma.. In this qualitative study, 25 participants described their primary care experiences after the upscheduling. A thematic analysis was used to understand the effects on APRN pain management practices.. The upscheduling of HCMs has greatly affected the pain management practices of APRNs in a state where Schedule II narcotic prescribing is forbidden. Findings will assist APRNs with improving patient access to care, implementing practice regulations, and exploring options for alternative pain therapies in primary care.. Upscheduling of HCMs has had a severe impact on APRNs, affecting their prescribing practices and leading to increased referrals. They noted limited treatment options, increased health care costs, and decreased access to care. The APRNs understand the problem of prescription opioid abuse, diversion, and misuse. A consensus model could standardize the regulatory process for APRNs, increase interstate mobility for practice, and increase access to APRN care nationwide.

To examine the effect on the trade in opioids through online illicit markets ("cryptomarkets") of the US Drug Enforcement Administration's ruling in 2014 to reschedule hydrocodone combination products.. Interrupted time series analysis.. 31 of the world's largest cryptomarkets operating from October 2013 to July 2016.. The proportion of total transactions, advertised and active listings for prescription opioids, prescription sedatives, prescription steroids, prescription stimulants, and illicit opioids, and the composition of the prescription opioid market between the US and elsewhere.. The sale of prescription opioids through US cryptomarkets increased after the schedule change, with no statistically significant changes in sales of prescription sedatives, prescription steroids, prescription stimulants, or illicit opioids. In July 2016 sales of opioids through US cryptomarkets represented 13.7% of all drug sales (95% confidence interval 11.5% to 16.0%) compared with a modelled estimate of 6.7% of all sales (3.7% to 9.6%) had the new schedule not been introduced. This corresponds to a 4 percentage point yearly increase in the amount of trade that prescription opioids represent in the US market, set against no corresponding changes for comparable products or for prescription opioids sold outside the US. This change was first observed for sales, and later observed for product availability. There was also a change in the composition of the prescription opioid market: fentanyl was the least purchased product during July to September 2014, then the second most frequently purchased by July 2016.. The scheduling change in hydrocodone combination products coincided with a statistically significant, sustained increase in illicit trading of opioids through online US cryptomarkets. These changes were not observed for other drug groups or in other countries. A subsequent move was observed towards the purchase of more potent forms of prescription opioids, particularly oxycodone and fentanyl.

Opioid abuse is a growing problem in civilian communities, and it has developed in the military as well. Telephone calls to poison centers requesting pill identification (ID) is a marker of drug abuse. This study identifies the number of pill ID calls made to the poison centers from areas containing and surrounding three Texas military bases during an 8-year period.. We performed a retrospective observational study identifying calls to certified poison centers in Texas from 2002 to 2009 that identified hydrocodone tablets and other pain medications. We noted the calls made from ZIP codes containing and surrounding the three largest military bases in Texas.. We reviewed 75,537 drug ID calls for any drug from the ZIP codes of interest. Total drug ID calls increased 105% and the number of calls for hydrocodone increased 463%.. In our study most of the drug ID calls from military communities in Texas were for hydrocodone. The rate of calls for hydrocodone increased more than the rate of calls for other analgesics from 2002 to 2009. Using drug ID calls as a surrogate of drug abuse, our results suggest that hydrocodone abuse has increased within military communities and that poison center data can be a reliable surrogate for prescription drug abuse near military bases. Future studies are needed to further understand the extent of this problem in military and civilian communities. We can use this information to heighten awareness, influence prescription practices, establish practice guidelines, and develop educational programs to mitigate the increasing rate of prescription analgesic abuse in the United States.

Non-medical prescription opioid use is a growing public health concern. Social media is an emerging tool to understand health attitudes, beliefs, and behaviors.. We retrieved a sample of publicly available Twitter messages in early 2014, using common opioid medication names and slang search terms. We used content analysis to code messages by user, context of message (personal vs general experiences), and key content themes.. We reviewed 540 messages, of which 375 (69%) messages were related to opioid behaviors. Of these, 316 (84%) originated from individual user accounts; 125 messages expressed personal experience with opioids. The majority of personal messages referenced using opioids to obtain a "high", use for sleep, or other non-intended use (87,70%). General attitudes regarding opioid use included positive sentiment (52, 27%), comments on others peoples opioid use (57, 30%), and messages containing public health information or links (48, 25%).. In a sample of social media messages mentioning opioid medications, the most common theme amongst English users related to various forms of opioid misuse. Social media can provide insights into the types of misuse of opioids that might aid public health efforts to reduce non-medical opioid use.

Vaccination against drugs of abuse shows efficacy in animal models, yet few subjects achieve effective serum antibody titers in clinical studies. A barrier to translation is the lack of pre-vaccination screening assays that predict the most effective conjugate vaccines or subjects amenable to vaccination. To address this obstacle, we developed a fluorescent antigen-based enrichment method paired with flow cytometry to characterize hapten-specific B cells. Using this approach, we studied naïve and activated B cells specific for structurally-related model haptens based on derivatization of the morphinan structure at the C6 position on oxycodone or at the C8 position on hydrocodone, and showing different pre-clinical efficacy against the prescription opioid oxycodone. Prior to vaccination, naïve B cells exhibited relatively higher affinity for the more effective C6-derivatized oxycodone-based hapten (6OXY) and the 6OXY-specific naïve B cell population contained a higher number of B cells with greater affinity for free oxycodone. Higher affinity of naïve B cells for hapten or oxycodone reflected greater efficacy of vaccination in blocking oxycodone distribution to brain in mice. Shortly after immunization, activated hapten-specific B cells were detected prior to oxycodone-specific serum antibodies and provided earlier evidence of vaccine failure or success. Analysis of hapten-specific naïve and activated B cells may aid rational vaccine design and provide screening tools to predict vaccine clinical efficacy against drugs of abuse or other small molecules.

In the past decade, more and more behavioral health providers have begun consultation practices in primary-care settings. Their availability makes multidisciplinary care a reality and the possibility of improved outcomes for patients with chronic pain more feasible. However, behavioral health providers encounter new ethical quandaries in providing services to patients with chronic pain and to the primary-care providers who plan their treatment. This article presents two cases to illustrate the questions that arise in delivery of primary-care behavioral health services to patients with chronic pain. Relevant professional ethical guidelines for psychologists, social workers, and physicians are examined and recommendations for addressing the gaps in extant guides are offered.

Studies have shown that position within networks of social relations can have direct implications on the health behaviors of individuals. The present study examines connections between drug use and individual social capital within social networks of drug users (n = 503) from rural Appalachian Kentucky, U.S.A. Respondent driven sampling was used to recruit individuals age 18 and older who had used one of the following drugs to get high: cocaine, crack, heroin, methamphetamine, or prescription opioids. Substance use was measured via self-report and social network analysis of participants' drug use network was used to compute effective size, a measure of social capital. Drug network ties were based on sociometric data on recent (past 6 month) drug co-usage. Multivariate multi-level ordinal regression was used to model the independent effect of socio-demographic and drug use characteristics on social capital. Adjusting for gender, income, and education, daily OxyContin(®) use was found to be significantly associated with greater social capital, and daily marijuana use was associated with less social capital. These results suggest that in regions with marked economic disparities such as rural Appalachia, OxyContin(®) may serve as a form of currency that is associated with increased social capital among drug users. Interventions focusing on increasing alternate pathways to acquiring social capital may be one way in which to alleviate the burden of drug use in this high-risk population.

OBJECTIVES. Cough mixture is the third most commonly abused substance in patients attending the Prince of Wales Hospital Substance Abuse Clinic. The content of the local cough mixture is not well researched. Paranoid psychosis manifesting as persecutory delusions and derogatory hallucination, as well as mood symptoms, is common in these patients. The natural history and outcome of such psychoses associated with cough mixture abuse are not well known. This study aimed to address these questions. METHODS. This was a retrospective study of cough mixture abuse in Hong Kong. Case records of cough mixture abusers currently receiving treatment at the 3 substance abuse clinics at the Prince of Wales Hospital, Alice Ho Miu Ling Nethersole Hospital, and the North District Hospital were retrieved for data collection. The patients' demographic data, duration and intake pattern of cough mixture, and use of any other drugs were documented. The presenting psychopathology, first urine toxicology results, diagnosis, treatment, number of hospitalizations, and course of the illness were also recorded. RESULTS. A total of 63 patients with the diagnosis of cough mixture abuse were identified in the database; 89% were male. The mean +/- SD age of the patients was 34.4 +/- 6.2 years; 67% were single and 83% were unemployed. The mean +/- SD age of onset of cough mixture abuse was 20 +/- 5 years. Psychiatric symptoms developed a mean +/- SD of 7.6 +/- 6.0 years after onset of abuse. According to the ICD-10 Mental and Behavioural Disorders criteria, the top psychiatric diagnoses were substance-induced psychotic disorder (67%), schizophrenia (19%), depressive disorder (11%), and dysthymia (10%). The most common ingredients in the urine sample at first presentation were promethazine (75%), pseudoephedrine (67%), codeine (60%), ephedrine (57%), zopiclone (17%), and hydrocodone (16%). Additionally, 16% of patients were in the priority follow-up group. The mean +/- SD follow-up period was 6.2 +/- 7.1 years during which there were 3.2 +/- 3.7 episodes of hospitalizations, with a mean +/- SD length of stay in each admission of 25.0 +/- 40.9 days. CONCLUSIONS. Promethazine, ephedrine, pseudoephedrine, codeine, and hydrocodone are the most common ingredients of cough mixture abused in this locality. Psychotic disorders are the most frequent psychiatric diagnosis associated with cough mixture abuse.

According to the American Association of Poison Control Centers, the number of medication identification requests (MIR) to poison centers has increased dramatically. In 2003, there were 617,414 calls compared to 1,070,537 in 2007. The purpose of this investigation was to characterize the nature of the most common requests to a poison center for medication identification.. To profile the MIR to a poison information center, the data from 2003 to 2007 were analyzed to identify all requests for medication identification. The subset of MIR data was extracted and analyzed to profile the requests by the specific medication and category. Descriptive statistics were used to characterize the data.. MIR were responsible for 193,006 calls: 24,643 in 2003, increasing to 55,473 in 2007. In 2003, there were inquiries about 1,261 different medications and in 2007 that increased to 3,165. During all but two of the five years, substances with known substance abuse potential accounted for 24 of the 25 most common MIR. Acetaminophen in combination with either hydrocodone or oxycodone dominated the requests. The most common identification request each year was for the brand-specific product Mallinckrodt 512 (acetaminophen/oxycodone).. The most frequent MIR involved medications with substance abuse potential, primarily opioids.. Poison center MIR data can provide important information to officials about substance abuse trends.

A variety of surveys and studies are examined in an effort to better understand the scope of prescription drug diversion and to determine whether there are consistent patterns of diversion among various populations of prescription drug abusers. Data are drawn from the RADARS System, the National Survey of Drug Use and Health, the Delaware School Survey, and a series of quantitative and qualitative studies conducted in Miami, Florida. The data suggest that the major sources of diversion include drug dealers, friends and relatives, smugglers, pain patients, and the elderly, but these vary by the population being targeted. In all of the studies examined, the use of the Internet as a source for prescription drugs is insignificant. Little is known about where drug dealers are obtaining their supplies, and as such, prescription drug diversion is a "black box" requiring concentrated, systematic study.

Increases in methadone and oxycodone related deaths have been recently documented in the United States. In response to these reports, the authors investigated cases over a six-year period in which postmortem toxicological analyses revealed the presence of methadone, hydrocodone, and oxycodone. The study was designed to determine whether regional methadone-associated mortality in Cuyahoga County reflected national trends and more specifically, to distinguish methadone mortality from other commonly used opioid analgesics. All records of decedents that were found to be positive for methadone, hydrocodone, and/or oxycodone in 1998-2003 were reviewed. The cause and manner of death and demographic information was compiled. The cases were divided into lethal intoxications and cases where a positive result was determined to be an incidental finding. Lethal intoxications as a result of only methadone, hydrocodone, or oxycodone were separated from polydrug intoxications. Thoroughout the study, an increase was observed in the number of positive cases. In contrast to recent national data, although the number of methadone-positive cases increased from 4 in 1998 to 18 in 2003, this did not result in an increase in methadone overdoses [1 death in 1998 (25%) to 4 deaths in 2003 (22%)]. Although the pharmacokinetic profiles differ, methadone, hydrocodone, and oxycodone lethal intoxications equally comprised 28-29% of cases in which these drugs were detected. There was an overlap in the range of blood concentrations observed for the drug-related death groups and the incidental finding groups. However, mean and median concentrations in oxycodone and hydrocodone related deaths were more than two times greater than those in non-drug-related deaths.

OBJECTIVE. Beginning in the late 1990's a marked increase in abuse of OxyContin emerged, which led to the development and establishment of a proactive surveillance program to monitor and characterize abuse, named the Researched Abuse, Diversion and Addiction Related Surveillance (RADARS) System. The main goal of RADARS was to develop proactive, timely and geographically sensitive methods to assess the abuse and diversion of OxyContin, along with a number of other Schedule II and III opioids with the aim of using this information to guide risk reduction interventions. Thus, its major focus was the detection of abuse of OxyContin and other commonly prescribed opioid analgesics at the three-digit ZIP code level across the country utilizing a number of different detection systems.. The detection systems selected were: (1) Quarterly-surveys of drug abuse experts who are knowledgeable about cases of prescription drug abuse; (2) Surveys of law enforcement agencies that detect diversion of prescription drugs; and (3) Poison Control Center reports of intentional misuse or abuse of prescription opioids. Collectively, the three systems provide overlapping coverage of over 80% of the nation's 973 three-digit ZIP codes.. Preliminary results indicate that prescription drug abuse is prevalent nationwide, but it seems to be heavily localized in rural, suburban and small urban areas. Our results also indicate that hydrocodone and extended and immediate release oxycodone products are by far the most widely abused drugs in the country, but the abuse of all prescription opioids seems to have grown over the 14 quarters since the inception of RADARS.. The next step in these studies is to develop regionally specific, risk-minimization-strategies, which is the goal of all risk-management programs. If successful, RADARS will serve as a prototype of such programs for any new drug approved that has measurable abuse potential.

Over the past decade, the misuse and abuse of opioid medications in the United States has risen dramatically. Although data show a substantial variation in the nonmedical use of individual opioids, relatively little is known about risk factors for the nonmedical use of specific opioid products. This study compared the prevalence and correlates of the nonmedical use of oral immediate-release hydromorphone (marketed under the brand name of Dilaudid), versus that of hydrocodone combination products using a nationally representative sample of the civilian noninstitutionalized United States population aged 12 years or older. Data were from the 2003 National Survey on Drug Use and Health. An estimated 31.3 million individuals reported lifetime nonmedical use of an opioid analgesic. Of these, 2.9 percent reported lifetime nonmedical use of Dilaudid, and 51.9 percent reported lifetime nonmedical use of hydrocodone combination products exclusive of nonmedical Dilaudid use. Nonmedical Dilaudid users were likely to be older, Caucasian, and to have reported a higher lifetime prevalence of heroin, cocaine and injection drug use, as well as nonmedical use of other opioids. Nonmedical Dilaudid users were at higher risk for engaging in more serious substance abuse-related behaviors than those who reported lifetime nonmedical use of hydrocodone combination products.

Controversy exists concerning whether abuse of oxycodone will increase after the introduction of generic controlled-release (CR) oxycodone. We evaluated the effect of FDA approval of generic CR oxycodone on the misuse/abuse of oxycodone, hydrocodone, methadone and morphine utilizing data from eight poison control centers (PCC). PCC intentional exposure (IE) reason codes were used as measures of abuse. Opioid-specific quarterly IE rates (per 100,000 population and per 10,000 patients) were calculated for 1 year before and after approval (March 24, 2004). Changes in regression slopes (1 year before to 1 year after) and in IE rates (1 quarter before to 1 quarter after) were analyzed using Poisson regression. The regression slopes for oxycodone, methadone and morphine did not change after approval but decreased significantly for hydrocodone. None of the prescription opioids' IE rates significantly increased after approval. When changes in oxycodone's IE rates were compared to the other opioids, no statistically significant differences were found, indicating a lack of time-opioid interaction. These results did not vary when population rates or patient rates were used. PCC data indicate that approval of generic CR oxycodone was not followed by an immediate unfavorable effect on the misuse/abuse of oxycodone.

This study was designed to determine the availability of web sites offering to sell opioid medications without prescriptions.. Forty-seven Internet searches were conducted with a variety of opioid medication terms, including "codeine," "no prescription Vicodin," and "OxyContin." Two independent raters examined the links generated in each search and resolved any coding disagreements. The resulting links were coded as "no prescription web sites" (NPWs) if they offered to sell opioid medications without prescriptions.. In searches with terms such as "no prescription codeine" and "Vicodin," over 50% of the links obtained were coded as "NPWs." The proportion of links yielding NPWs was greater when the phrase "no prescription" was added to the opioid term. More than 300 opioid NPWs were identified and entered into a database.. Three national drug-use monitoring studies have cited significant increases in prescription opioid use over the past 5 years, particularly among young people. The emergence of NPWs introduces a new vector for unregulated access to opioids. Research is needed to determine the effect of NPWs on prescription opioid use initiation, misuse, and dependence.

Here we present the unusual case of an adolescent with cystic fibrosis presenting with declining pulmonary function and diffuse micronodular pulmonary disease. This case illustrates the radiographic and pathologic findings associated with the intravenous injection and pulmonary arterial embolization of insoluble pharmaceutical-tablet constituents. The number of first-time users reporting nonmedical use of prescription pain relievers is increasing dramatically, especially in adolescents. Recognition of both the diagnostic imaging features and histologic features on lung biopsy are critical steps for early diagnosis, intervention, and potential prevention of sudden death in these at-risk patients.

This study examines the nature, extent and consequences of prescription drug abuse among 143 ecstasy users in Miami. Participants were recruited through nightclub and college campus outreach, and through respondent referrals. Instrumentation included the Risk Behavior Assessment, Substance Abuse Module and Center for Epidemiological Studies Depression Scale. Median age was 23, 42% were female and 50% Hispanic. An arrest history was reported by 44%, and 33% reported prior drug/alcohol treatment. Prescription drug abuse was reported by 87%; alprazolam (57%), oxycodone (36%), hydrocodone (32%) and diazepam (30%) were cited most often. Prescription drug abusers were more likely to report polydrug use, drug treatment histories, risky drug use behaviors, and symptoms of depression. They also reported numerous physical, psychological and social consequences of prescription drug abuse. Additional studies among larger samples are needed to understand the processes of prescription drug access and the extent of integration in club drug using cultures.

To describe profound hearing loss associated with hydrocodone overuse and the successful rehabilitation of these patients with cochlear implantation.. Retrospective review.. A tertiary otologic referral center.. Twelve patients with rapidly progressive hearing loss and a concurrent history of hydrocodone overuse.. Comprehensive medical histories, physical findings, audiometric tests, and, in those patients undergoing cochlear implantation, postimplantation performance data were reviewed.. Clinical characteristics of hydrocodone-related hearing loss and open set word and sentence performance in those patients undergoing cochlear implantation.. Hydrocodone overuse was associated with rapidly progressive sensorineural hearing loss in 12 patients. In four patients the initial presentation was unilateral, and two of the patients experienced vestibular symptoms. None of the 12 patients experienced improved thresholds after high-dose prednisone. Seven of the eight patients undergoing cochlear implantation have demonstrated early success with their devices.. Hydrocodone is frequently prescribed in combination with acetaminophen for the relief of pain and has a side effects profile similar to other medications in its class. Although not described previously, overuse or abuse can be associated with a rapidly progressive sensorineural hearing loss. These patients can be successfully rehabilitated with cochlear implantation.

A series of 8-alkyl-3-methoxy-17-methylmorphinan-6-ones (3C) and -isomorphinan-6-ones (3T) were prepared by conjugate addition of lithium dialkylcuprates to the corresponding 7,8-didehydro-6-ones 2C and 2T. These 17-methyl compounds were potent analgesics and were converted to mixed narcotic agonists-antagonists 7-10, by replacement of the 17-methyl groups with cycloalkylmethyl moieties. The 8 substituent modified the type of activity observed. One of these compounds, 17-(cyclobutylmethyl)-3-hydroxy-8 beta-methylmorphinan-6-one (10Ca), had an agonist-antagonist ratio of 0.1. Compound 10Ca did not support or cause dependence in rats. This compound, however, appeared to be a typical narcotic agent in morphine-dependent monkeys.
