(--)-alpha-Acetylmethadol effects on alcohol and diazepam use, sexual function and cardiac function.

Selected behavioral and physiological effects of maintenance on (--)-alpha-acetylmethadol (LAAM) were examined for 67 men beginning LAAM maintenance. Thirty-four began LAAM maintenance after 1 month or more on methadone; 33 others were using street heroin immediately before beginning LAAM. Subjects were followed for 20 weeks on LAAM; assessment focused on changes in alcohol and diazepam use, sexual behavior and testicular function, and cardiovascular function. There was a trend toward increased alcoholism-related behaviors, but not consumption of alcohol, when on LAAM. Use of diazepam remained low. Subjects reported slightly enhanced sexual activity: reported number of ejaculations tended to increase, although interest in sexual activity remained constant. Semen volume values remained in the low normal range. In contrast to an earlier published report of reduced sperm motility in methadone and heroin users, normal motility was noted in this sample. The incidence of abnormal sperm morphology decreased from baseline to the end of the study. Cardiovascular function, as assessed by response to standard exercise, was unchanged during LAAM maintenance. Electrocardiograms revealed minor abnormalities prior to beginning LAAM maintenance; but these abnormalities did not consistently change during treatment. There is little evidence that the effects of LAAM maintenance differ from the effects of methadone maintenance on these behavioral and physiological functions.

Withdrawal from heroin in three or six weeks. Comparison of methadyl acetate and methadone.

A randomized clinical trial compared four methods of outpatient withdrawal from heroin. Sixty-one subjects were assigned in a double-blind manner to treatment with either methadone or methadyl acetate. Within each drug group, subjects were assigned to detoxification programs either within the standard three-week period or in an extended six weeks of treatment. Outcome measures included retention to the end of the dosing schedule, use of illicit drugs during treatment, subjective discomfort, satisfaction, staff ratings of global progress, and durability of change at a three-month follow-up. Methadyl acetate performed similarly to methadone in most respects. Six-week withdrawal showed some temporary benefits over standard treatment, but these advantages should be weighed against the greater cost of the longer treatment and similarity of follow-up outcome.

Heroin addict responses to six weeks of detoxification with LAAM.

This paper describes the range of experience of 28 heroin addicts who received LAAM instead of methadone over six weeks in an outpatient detoxification program. Four patients are singled out to illustrate the variety of response during withdrawal, temporary abstinence from drugs, and social adjustment. The paper explores the motivation of patients and both their physical and subjective responses to the detoxification attempt. By describing a variety of patients, the paper documents clinical responses that cannot be communicated in statistical summaries or single-case reports. Overall, the cases illustrate the difficulties of brief-stay outpatient detoxification from heroin. Clinicians should expect to see only small steps toward rehabilitation during a patient's attempt to taper from opiates, but even minimal progress may justify the use of detoxification programs as a link between "street life" and the decision to enter long-term treatment.

Control of vasopressin secretion in the newborn lamb.

The plasma sodium, osmolality, and arginine vasopressin (AVP) responses to phlebotomy, hypertonic saline, water loading and fluid restriction were studied in 2--49 day old lambs. Phlebotomy of 10 and 20% of the lamb's estimated blood volume produced 37- and 44-fold increments in plasma AVP, without a concomitant change in plasma sodium or osmolality. The infusion of 10 mEq/kg sodium chloride produced a 12% rise in plasma sodium concentration accompanied by a 7-fold rise in plasma AVP. Water loading with 100 ml/kg hypotonic fluid produced a significant fall in plasma sodium concentration (10.7%) and a decrease in plasma AVP. Eighteen hr of water deprivation evoked a 7-fold increase in AVP. These results indicate that the newborn lamb is capable of responding appropriately to known stimuli for AVP secretion. The stimulus response ratio (SRR): (formula: see text) of newborn lambs was nearly identical after hypertonic saline and water loading and was also quite similar to that of the adult ewe after a saline challenge. The SRR of water deprived lambs was greater than that after the other stimuli, presumably reflecting combined volume and osmolar stimuli. We conclude that the neurohypophysis and the volume receptor systems of the newborn lamb are capable of appropriate, mature AVP responsiveness during the first days of extrauterine life.
