The aim of this double-blind, placebo-controlled study was to evaluate the efficacy of intravenous magnesium sulphate (MgSO(4)) on the need for chlormethiazole in pure or polysubstance opiate detoxification. Forty-one inpatients suffering from pure and polysubstance opiate dependence were treated with morphine sulphate pentahydrate in a gradual detoxification program. Morphine reduction took about 11 days.

Within hours the patients tolerated full doses of naltrexone. This technique enables patients to transfer easily, quickly, and safely from methadone to naltrexone maintenance.

There have been several suggestions to protect the injecting population from further harm, but focused mainly on the use of sterile needles and syringes as well as information about safer sexual behavior. This study examined a total of 366 IVDUs at the drug dependence out-patient ward of the Psychiatric University Clinic of Vienna.

In methadone maintenance therapy methadone plasma concentrations of 400 ng/ml are necessary to suppress any further opiate action and to provide stabilized maintenance. In a controlled study we have searched for a differentiation in autonomous activation between patients having low and high methadone plasma levels, using static and dynamic pupillometry and habituation of skin conductance response. Results show that there is no difference in psychophysiological response between patients with high (greater than 400 ng/ml) or low (less than 400 ng/ml) plasma levels of methadone.

Every opportunity should be used to reduce the risk of HIV-1 infection and transmission among intravenous drug users (IVDUs). Methadone maintenance is widely accepted to keep the drug user away from risk-laden practices and to stop intravenous drug use. In order to minimize the diversion and intravenous abuse of methadone in maintenance programs, the effects of a combined naloxone/methadone preparation through oral intake and the effects of an intravenous administration were tested.

In a double-blind placebo-controlled trial of 18 patients, methohexitone blocked objective signs of opiate withdrawal caused by a bolus injection of naloxone. Furthermore, in continuing the naloxone therapy for 48 hours, no withdrawal signs appeared. Levels of withdrawal distress returned to normal levels within six days.

We report the results of a survey of a total of 553 intravenous drug users (IVDUs) investigated at the drug addiction out-patient unit of the Psychiatric Department of Vienna University for antibodies to human immunodeficiency virus (HIV-1) using both enzyme-linked immuno sorbent and Western blot assays. HIV-1 antibodies were found 1985/86 in 8.5%, 1986/87 in 14.

To date, no satisfying solution has been found to the problem of how to avoid the distressing withdrawal symptoms accompanying opiate detoxification. By administering staggered doses of naloxone to the patient while under tiapride (Delpral-R), the various discomforts were satisfactorily reduced and the detoxification syndrome could be limited to 50 hours. This study covers 15 patients who had an average addiction history of more than 7 1/e years, and who underwent inpatient rapid opiate withdrawal treatment lasting an average of five days.

The rapid spread of HIV infection among intravenous drug abusers plays an increasing role in the AIDS epidemic. In this context the Austrian government changed politics and introduced a methadone maintenance program 1987, to reach more intravenous drug addicts and to stop intravenous drug abuse of this clients. 119 intravenous drug users were anonymously tested for HIV antibodies between April 18 and May 17, 1988 at the out-patient clinic of the Psychiatric University clinic of Vienna and were examined by means of a standardized questionnaire.

The VPTS includes a special selection and combination of experimental situations, physiological measurements, behavioral measurements and data analysis. At weekly intervals, the subjects received randomized single oral doses of placebo, 150 mg, 300 mg and 900 mg tenilsetam (TEN) and 5 mg co-dergocrine-mesylate (CDM) as reference drug.

This study presents detailed information concerning these four aspects. Experimental situations are related to the human model of information processing, where short changes of stimulus-reaction-correlated processes are selected: resting conditions (eyes open, eyes closed), habituation-orienting test, psychomotor-performance test, signal-detection test and reaction-time test.

For opiate detoxification 6 volunteer opiate addicts were intravenously administered 10 mg naloxone within one hour while under barbiturate anesthesia. During administration of naloxone none of the patients demonstrated significant changes in the hemodynamic parameters of heart rate, mean arterial pressure, cardiac index, peripheral resistance or in the oxygen saturation. After patients awoke from anesthesia, they experienced no or only minimal withdrawal symptoms.
