fentanyl and Addiction, Opioid

fentanyl has been researched along with Addiction, Opioid in 419 studies

Fentanyl: A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1078)
fentanyl : A monocarboxylic acid amide resulting from the formal condensation of the aryl amino group of N-phenyl-1-(2-phenylethyl)piperidin-4-amine with propanoic acid.

Trial Outcomes

"Change From Placebo in VAS Score for Do You Feel Any Drug Effect? by Study Week and Simulated mu Opioid Receptor Occupancy (μORO)"

"Participants completed a visual analog scale (VAS) that ranged from 0 - 100, with 0 meaning not at all, and 100 meaning the most extreme drug effect 30 minutes (± 5 minutes) before and 15, 30 , 45, 60, 75, 90, 120, 150, 180, 210, 240, 270, and 300 minutes (± 5 minutes) after hydromorphone challenge. The drug in question was hydromorphone (6 or 18 mg) or placebo. For each hydromorphone challenge week, a mixed-effects model with period (where period is day), hydromorphone sequence, and hydromorphone dose as fixed effects and subject nested within hydromorphone sequence as a random effect were used for analysis.~Change from placebo was calculated as Active Challenge result - Placebo Challenge result. Values that approach 0 (implying little difference between the Active Challenge result and the Placebo Challenge result) indicate effectiveness of the opioid blockade.~Row titles include Study Week: mean predicted mu opioid receptor occupancy for 6 mg / 18 mg challenge dosages" (NCT02044094)

The drug in question was hydromorphone (6 or 18 mg) or placebo.~For each hydromorphone challenge week, a mixed-effects model with period (where period is day), hydromorphone sequence, and hydromorphone dose as fixed effects and subject nested within hydromorphone sequence as a random effect were used for analysis.~Blockade is achieved if the upper bound of the 95% confidence interval is <= to the non-inferiority margin of 11."

Change From Placebo in Reinforcing Effects (Breakpoint) by Study Week and Simulated mu Opioid Receptor Occupancy (μORO)

"This endpoint explores the correlation between the reinforcing effects of hydromorphone and simulated mu opioid receptor occupancy.~Data are reported as change from placebo least square mean of Log10 transformed values for reinforcing effects. Reinforcing Effects tasks began >= 5 hours after hydromorphone challenge. Participants made 12 choices between a preference for working for the amount of hydromorphone dosed that day or for money. The hydromorphone break point value is assigned to the highest level of hydromorphone units earned, with 1 unit having a breakpoint value of 5 and 12 units with a value of 2160.~Change from placebo was calculated as Active Challenge result - Placebo Challenge result. Values that approach 0 (implying little difference between the Active Challenge result and the Placebo Challenge result) indicate effectiveness of the opioid blockade.~Row titles include Study Week: predicted mu opioid receptor occupancy for 6 mg / 18 mg challenge dosages" (NCT02044094)

Predicted mu Opioid Receptor Occupancy (μORO) by Mean Buprenorphine Concentrations and Study Week

"A population pharmacokinetic/pharmacodynamic (PK/PD) model was developed to model the relationship between buprenorphine plasma concentrations and brain μORO based on 2 published clinical trials. This model used individual buprenorphine plasma concentrations measured to derive muORO individual predictions that were further described using summary statistics. The relationship between buprenorphine plasma concentration and μORO was best described by a maximal effect (Emax) model:~µORO = E(max)*Cp / EC(50) + Cp~Where Cp is the plasma concentration of buprenorphine, Emax is the maximal μORO, and EC50 is the plasma concentration of buprenorphine that is expected to achieve 50% of the maximal μORO. A direct (instantaneous) relationship between buprenorphine plasma concentration and µORO, i.e. without equilibration delay, was assumed.~Row title format: Study Week: buprenorphine plasma concentrations for placebo/ 6 mg / 18 mg challenge dosages" (NCT02044094)

Reinforcing Effects Of the Daily Randomized Hydromorphone Challenge as Measured by the Mean Hydromorphone Break Point Value at Weeks 1-12

"The ability of RBP-6000 to reduce the reinforcing effects of hydromorphone used money as a choice alternative to hydromorphone.~Reinforcing Effects Tasks began no earlier than 5 hours after randomised hydromorphone administration for each day. Each test consisted of the participant making 12 choices between a preference for working for the amount of hydromorphone dosed earlier that day or for money (each choice therefore has a scale of 0-12). The hydromorphone break point value is the ratio of the highest number of choices for hydromorphone to the highest number of choices for money. Hydromorphone breakpoint values were then analysed by week using a repeated measures mixed-effects model with period, hydromorphone sequence, and hydromorphone dose as fixed effects and subject nested within hydromorphone sequence as a random effect. Analyses were carried out on the log10 transformed hydromorphone breakpoint value." (NCT02044094)
