Mood and affect during detoxification of opiate addicts: a comparison of buprenorphine versus methadone.

Twenty-six in-patients with Diagnostic and Statistical Manual version IV (DSM-IV) criteria for opioid dependence were selected at random to receive either a combination of an 11-day low-dose buprenorphine and a 14-day carbamazepine regimen (n = 14) or a combination of an 11-day methadone and a 14-day carbamazepine regimen (n = 12) in a double-blind, randomized 14-day in-patient detoxification treatment. Patients with buprenorphine and carbamazepine showed a significantly better psychological state after the first and second weeks of treatment. Above all, the buprenorphine-treated patients demonstrated a less marked tiredness, sensitiveness and depressive state as well as a more prominent elevated mood during the detoxification process. Seven non-completers (after 7 days: four of 12 = 33.3%; after 14 days: seven of 12 = 58.3%) were treated with methadone and carbamazepine and five non-completers (after 7 days: two of 14 = 14.3%; after 14 days: five of 14 = 35.7%) received buprenorphine and carbamazepine. The difference in the overall dropout rate after day 14 was not significant. The present study supports the hypothesis that the combination of buprenorphine and carbamazepine leads to a better clinical outcome than does a combination of methadone and carbamazepine in the detoxification of opioid addicts with additional multiple drug abuse. The buprenorphine and carbamazepine-regimen provides a more effective short-term relief of affective disturbances than does methadone and carbamazepine. No severe side effects occurred during the treatment period in both groups.

[Hawaiian baby woodrose: (Psycho-) Pharmacological effects of the seeds of Argyreia nervosa. A case-orientated demonstration]. / Hawaiianische Holzrose: (Psycho-)Pharmakologische Wirkungen der Samen der Argyreia nervosa Eine fallbezogene Darstellung.

The seeds of the Hawaiian baby woodrose ( Argyreia nervosa) are used by adolescents as a supposed hallucinogenic drug. These seeds are legally available and broadly sold. The active components are alkaloids structurally related to lysergic acid diethylamide (LSD). However, the psychic effects are very different from those of LSD and are dominated by rather sedative, uncomfortable autonomic disturbances similar to the effects of scopolamine. The (psycho)pharmacological profile is described on the basis of the active substances lysergacidamide and lysergacidethylamide (and their isomers). It is shown that neither the substances themselves nor the mixture are able to evoke LSD-like perceptual variances. The exposure of Argyreia nervosa is described focusing on potential fetal distress by contained ergometrine and the case history of an intoxication.

Detoxification of opiate addicts with multiple drug abuse: a comparison of buprenorphine vs. methadone.

Over the last few years, there has been a growing tendency for opioid addicts to abuse multiple drugs, although many patients are in substitution therapy with methadone. Abuse of multiple drugs leads to a more complicated withdrawal syndrome; it is therefore necessary to investigate new drug strategies as a treatment for detoxification. Buprenorphine appears to be an effective and safe drug in opioid-addicted patient detoxification. In this study, we have compared the short-term efficacy of an 11-day low-dose buprenorphine/14-day carbamazepine regime [BPN/CBZ] (n = 14) to an 11-day methadone/14-day carbamazepine regime [MET/CBZ] (n = 12) in a double-dummy, randomized 14-day inpatient detoxification treatment study. Twenty-six inpatients met the DSM-IV criteria for opioid dependence and were included in this study. All patients abused various additional drugs. Fourteen of 26 patients (53.8 %) completed the study. Seven non-completers (seven of 12 = 58.3 %) were treated with methadone/carbamazepine and five non-completers (five of 14 = 35.7 %) received buprenorphine/carbamazepine, but the difference in the dropout rate was not significant. However, patients with buprenorphine/carbamazepine showed significantly fewer withdrawal symptoms after the first two weeks of treatment. The present study supports the hypothesis that buprenorphine/carbamazepine is more effective than methadone/carbamazepine in detoxification strategies for opioid addict with additional multiple drug abuse. No severe side effects occurred during treatment in either group.

[Detoxification of poly-substance abusers with buprenorphine. Effects on affect, anxiety, and withdrawal symptoms]. / Detoxifikation polytoxikomaner Patienten mit Buprenorphin. Auswirkungen auf Affektivität, Angst und Entzugssymptomaik.

We used an open-labeled, 21-day inpatient detoxification treatment to compare the short-term effects of a 10-day buprenorphine plus 19-day carbamazepine regimen (n = 15) to a 14-day oxazepam plus 19-day carbamazepine regimen (n = 12) during rapid detoxification from opioids and other abused drugs. Somatic and psychopathological changes were assessed using the following rating scales: ASI, HAMD, SCL-90-R, and SOWS. Eighteen of 27 patients (67%) completed the study. Four dropouts (27%) were treated with buprenorphine/carbamazepine (BPN/CBZ) and the other five dropouts (42%) were treated with oxazepam/carbamazepine (OXA/CBZ). Repeated measures analysis of variance showed that SOWS scores were significantly less pronounced with BPN-CBZ than with OXA/CBZ. On the first day of admission, no significant difference in HAMD scores was detected (BPN/CBZ 11.6, BPN/CBZ 1.0). On day 14, HAMD was significantly less pronounced in BPN/CBZ (3.0) than in OXA/CBZ (6.1). BPN/CBZ showed a significant improvement in the ASI score on days 7 and 14 compared with OXA/CBZ. Three of nine items of the SCL-90-R showed a trend toward less pronounced outcome in BPN-CBZ. No severe side effects occurred during treatment in either group. The buprenorphine/carbamazepine regimen provided significantly more effective relief from affect disturbances and withdrawal syndromes than the oxazepam/carbamazepine regimen. The pharmacological basis of these effects of buprenorphine (kappa-antagonism activity,mu-agonism activity) are discussed.

Buprenorphine and carbamazepine as a treatment for detoxification of opiate addicts with multiple drug misuse: a pilot study.

The growing tendency of opioid addicts to misuse multiple other drugs leads to the investigation of new pharmacostrategies to prevent patients from suffering life-threatening complications and minimize the withdrawal symptoms. The short-term efficacy of a 10-day low-dose buprenorphine/19-day carbamazepine regime (n = 15) to a 14-day oxazepam/19-day carbamazepine regime (n = 12) in an open-labelled 21-day inpatient detoxification treatment was compared. Twenty-seven men and women dependent on opioids and misusing other drugs admitted to a detoxification unit were included in this protocol. Eighteen of 27 patients (67%) completed the study. Four non-completers (27%) received buprenorphine/carbamazepine (four of 15) and five non-completers (42%) were treated with oxazepam/carbamzepine (five of 12), but the difference in the dropout rate between the two treatment strategies was not significant.The buprenorphine/carbamazepine regime provided significantly more effective relief of withdrawal symptoms during the first week of treatment. No severe side effects occurred during treatment in both groups. The present study supports the hypothesis that buprenorphine/carbamazepine is more effective than oxazepam/carbamazepine in rapid opioid detoxification in patients with additional multiple drug misuse and both regimens were safe with no unexpected side effects.

[Angel trumpets: case report of drug-induced psychosis caused by Brugmansia insigniis]. / Engelstrompeten: Falldarstellung einer drogeninduzierten Psychose durch Brugmansia insigniis.

A case of a psychosis induced by ingestion of blossoms of the solanum Brugmansia insigniis is presented. This plant is used by young persons as a hallucinogenic drug. The psychopathology of this kind of intoxication has not been documented in the literature up to now. It is characterized by anticholinergic effects (e.g. mydriasis), disturbances of orientation, incoherent thoughts, flight of ideas, tangential thinking illusions, auditory hallucinations (e.g. verbal hallucinations), visual hallucinations and affective lability. In addition to hyoscine (scopolamine) and atropine, hallucinogenic effects may be related to previously identified alkaloids.
