3-methylmethcathinone and cathinone

To define the characteristics of synthetic cathinone users admitted to hospital including clinical and laboratory parameters and the complications of use.. Retrospective single-center study of patients treated for acute cathinone intoxication and complications of cathinone use between January 2010 and January 2016.. A specialized clinical toxicology unit at an academic tertiary care center in Southern Germany serving a population of about 4 million.. 81 consecutive patients with laboratory-confirmed use of cathinones who presented for acute intoxication or complications of cathinone use were retrospectively analyzed.. The patients were predominantly male (64%, 52/81) with a median age of 34 years. 60 were admitted for signs of acute intoxication while 21 suffered from complications of cathinone use. 70% of acutely intoxicated patients had an increased creatinine phosphokinase. Only a minority of patients presented with a sympathomimetic toxidrome. Three patients had infectious complications, 10 prolonged psychosis, 6 rhabdomyolyses and/or kidney failure, and two patients died. Based on presentations, cathinone use has increased with the first cases seen in 2010. Opiates/opioids are the main co-ingested drugs of abuse. The pattern of cathinone use shifted from methylone in 2010/2011 to 3,4-methylenedioxypyrovalerone (MDPV) and 3-methylmethcathinone (3-MMC) in 2014/2015. We conclude that in our setting "typical" cathinone users are males in their thirties. They are seldom drug naïve and regularly co-ingest illicit drugs. Preventive measures have to be tailored to these difficult to reach patients. Present efforts to educate young clubbers in their late teens may fail to reach the pertinent demographic.

The study presents the characteristics of the use of new psychoactive substances (NPS), the perceived problems experienced by users, and the reasons for cessation or cutting down. The research focused mainly on synthetic cathinones and the use of 3-MMC in Slovenia.. In order to research the characteristics of NPS use, we used a questionnaire which had been developed to determine the characteristics of the use of ATS and cocaine in the context of nightlife and was elaborated in our study on the use of mephedrone. The final non-representative sample included 249 users of NPS from Slovenia, who had completed an on-line survey over a period of 5 months in 2014. Part of the sampling was conducted on the ground and with the help of peer-groups. DrogArt's outreach workers and correspondents visited open public places, clubs, and discotheques to encourage users to participate in the survey.. Most users of NPS in Slovenia have tried NPS from the groups of synthetic cathinones and amphetamines. Most respondents included in the sample (67.9%) have tried 3-MMC, while 43.0% have tried methylone and 37.3% have tried mephedrone (4-MMC). Users attributed greater risks to the use of new drugs and preferred the effects of traditional drugs to those of new drugs. The most frequently reported problems were depression (55.2% of users), concentration difficulties (44.0%), damage to the mucous membrane of the nose and to the throat (39.8%), feelings of fear and anxiety (39.4%), and tingling in the arms or legs (34.4%). The main reasons for cutting down or discontinuing the use of NPS were 'fear of the health consequences', 'actual health consequences', and 'growing weary of using'. Among users of NPS, 7% have sought help, while 9.1% have considered doing so. The results also highlight differences between the NPS drug markets in Slovenia and the United Kingdom.. In 2014, the most frequently used NPS in Slovenia were synthetic cathinones such as 3-MMC. Users experienced various problems related to the use of NPS. However, they are familiar with recommendations on harm reduction and want additional information on the harmful effects of the use of NPS. Based on the obtained results, we can develop specific interventions in the area of harm reduction.

3-Methylmethcathinone (3-MMC) is a synthetic cathinone stimulant structurally related to the new psychoactive substance (NPS) mephedrone (4-methylmethcathinone, 4-MMC). We describe a case series of analytically confirmed intoxications involving 3-MMC presented to emergency departments in Sweden and included in the STRIDA project.. Observational case series of consecutive patients with self-reported or suspected use of NPS presenting to hospitals in Sweden between August 2012 and March 2014.. NPS analysis was performed by a liquid chromatography-mass spectrometry (MS)/MS method that is updated with new substances as they appear. Data on clinical features were collected during Poisons Information Centre consultations and retrieved from medical records.. 3-MMC was detected in 50 (6.4%) of the 786 cases included in the STRIDA project during the 20-month study period, with the peak occurring in August 2013. The age range of patients testing positive for 3-MMC was 17-49 years (median 24) and 76% of them were men. The 3-MMC concentration in serum ranged between 0.002 and 1.49 μg/mL (median, 0.091) and between 0.007 and 290 μg/mL (median, 3.05) in urine. Co-exposure to other NPS and/or traditional drugs was very common, and 3-MMC mono-intoxication was found in only 4 (8%) cases. The most frequent clinical features were tachycardia (48% of cases) and agitation (42%). Other features included a reduced level of consciousness (32%), dilated pupils (24%), hallucinations (20%), diaphoresis (12%), seizures (8%), and hyperthermia (6%). Most patients (60%) needed hospital care for only 1 day but in 8% for 3 days or longer.. The majority of patients with analytically confirmed 3-MMC exposure had sympathomimetic features similar to those associated with mephedrone intoxication. However, the high incidence of co-exposure to other drugs makes the clinical interpretation difficult. Nevertheless, 3-MMC was associated with a high admittance rate to intensive care (30%), and detected in two cases with a fatal outcome, suggesting that 3-MMC is a harmful drug.
