Oxilorphan (levo-BC-2605) is a new, long-acting, narcotic antagonist that has agonist properties. Twenty-one (21) heroin addicts in Los Angeles were detoxified and given at least one oral dose of oxilorphan. Only three (14.3%) patients took daily doses for 14 days, which was the maximal time allowed for oxilorphan administration in this study. The remainder discontinued oxilorphan because of subjective side effects or for unknown reasons. Side effects most responsible for dropouts were dysphoria, insomnia, weakness, hallucinations, nausea, drowsiness and anorexia. Oxilorphan provided 24-hour protection with a single, oral dose, but subjective side effects encountered during inductiolinical trials with oxilorphan should be attempted with other addict populations to fully determine its potential therapeutic value.

Effect of ethanol on adenosine 3', 5' cyclic monophosphate (cAMP), calcium (Ca) and magnesium (Mg) excretion was studied in controlled clinical conditions in man. Seven male volunteers served as their own controls. In 5 subjects cAMP excretion was primarily suppressed by ethanol. Ethanol appeared to have a biphasic effect on Ca excretion, an initial stimulation followed by a conservation phase. Mg excretion was stimulated by ethanol in 5 subjects. Subjects having nausea and vomitus and the most severe hangover symptoms had the lowest urinary Ca excretion and the lowest imitial cAMP excretion. Ca and Mg metabolism and the susceptibility of the body to the toxic effects of ethanol appeared to be interrelated.

The incidence of side effects due to two dosage regimens of minocycline was examined over a 5-day period. A total of 60 normal women volunteers were randomly assigned in a double-blind manner to either a group who took 100 mg of minocycline twice a day or a group who took 75 mg of minocycline twice a day for 5 days. Both groups were comparable from the standpoints of age, size, race, and the use of oral contraception, nicotine, and ethanol. They were seen on a daily basis, and symptoms were evaluated by both volunteers (from diaries) and physicians. Minocycline serum concentrations were determined on blood samples taken 2 h after the a.m. dose. Volunteers taking 150 mg of minocycline per day had significantly lower serum antibiotic concentrations than those taking 200 mg per day. However, both low- and high-dose groups exhibited similar incidence and prevalence of recorded symptoms, with the single exception of nausea, where the low-dose group had fewer symptoms than the high-dose group (P = 0.035). Symptomatic volunteers did not have higher serum concentrations of minocycline than their asymptomatic counterparts. When either weight or surface area was examined with antibiotic serum concentration there was a significant inverse correlation between the two on day 2 for both groups and also on day 4 for the low-dose group. It is concluded that, in women, a dose of 150 mg of minocycline per day is associated with the same degree of side effects as a dose of 200 mg per day.

Liver alcohol dehydrogenase (ADH) represents the main enzyme of normal alcohol metabolism. Total activity of this enzyme varies largely due to the occurrence of isoenzymes and of genetic polymorphisms. One genetic variant, called "atypical", is characterized by a higher specific activity. In carriers of this variant enzyme an initially faster rate of ethanol metabolism leads to higher blood acetaldehyde levels. Acetaldehyde, as a toxic intermediary metabolite, causes tachycardia, nausea and flushing of the face. A high frequency for "atypical" ADH is observed in mongolid races and consequently a hypersensitivity to alcohol is often observed in Orientals. Hence, certain genetically determined enzyme patterns may represent an aversive factor with regard to alcohol consumption. In Caucasians the phenotypes with "atypical" ADH are less frequent. However, in individuals with the "atypical" variant regular intake of alcohol may lead to an increased organotoxicity due to acetaldehyde.

Medicaments are used to prepare for instrument abortions in the 1st trimester and as inducers of abortion in the 2nd trimester. The effects, side effects, and dangers depend on the substances used and the route of application, which can be vaginal, cervical, injection, instillation, extraamniotic, intraamniotic, intravenous, or intramuscular. In the past, intraamniotic instillation of a 20% salt solution was the most common 2nd trimester method in Japan, the US, and Eastern Europe, giving a success rate of 90%. Serious side effects prompted substitution of extraamniotic instillation, which rarely produces serious side effects. Instillation of a 60% urea solution into the amniotic fluid in combination with oxytocin or prostaglandin produces an abortion in 13-21 hours, with a failure rate of 3% and a frequency of cervical laceration of under 1%. Extraamniotic use of a .1% solution of rivanol yields a success rate of about 85%, with a relatively long average time to explusion of 24-41 hours. In case of failure the procedure can be repeated. The advantage of the Rivanol method is the rarity of infectious complications. Alcohol is not used as a human abortifacient because it produces necrosis in the decidua and placenta. Prostaglandins are used in most 2nd trimester abortions. Research is underway to identify derivatives that will have an extended uterine impact without serious side effects. Different routes of administration have different effectiveness rates and dangers. All prostaglandins cause side effects including pain during uterine contractions, gastro-intestinal reactions, nausea, vomiting, fever, and headaches. Specific preparations are associated with other effects, some of them life-threatening. Emergency treatment should be available when these substances are used. Adjuvant measures may be employed before adminstration of an abortifacient agent to soften the cervix, or after administration to hasten the procedure. The choice of procedure depends upon the personality, health, and other characteristics of the woman and the experience of the doctor and the clinic.

The mechanisms underlying the frequent association of nausea and vomiting with elevations of plasma vasopressin(PAVP) were studied in man and rat. After oral water loads (N = 16), plasma osmolality fell in all human subjects and was associated with a decline in PAVP in 14 asymptomatic human subjects. In 2 human subjects, nausea occurred and was associated with increases in PAVP, without changes in blood pressure. During ethanol infusion (N = 28), PAVP was suppressed unless nausea supervened. In 4 nauseated human subjects, PAVP escaped from ethanol inhibition and rose to levels 10 times basal, despite the absence of hemodynamic changes. Apomorphine, a potent dopamine agonist and emetic agent, was administered to human volunteers in doses of 7 to 24 microgram/kg. There was no increase in PAVP in 3 human subjects who remained asymptomatic (7 to 16 microgram/kg). Ten human subjects experienced nausea after 16 microgram/kg, which was followed shortly by marked increases in PAVP. Emesis occurred in 5 human subjects given 16 to 24 microgram/kg, and was followed by PAVP levels similar to those seen with nausea alone. In 7 human subjects from the nausea group, the repeat study (16 microgram/kg) after pretreatment with dopamine antagonist (haloperidol, N = 4; fluphenazine, N = 3) resulted in complete blockage of apomorphine-induced AVP release. In rats, which lack an emetic reflex, apomorphine doses of 200 microgram/kg induced only slight increases in PAVP when compared to the response to 16 microgram/kg in man. These studies indicate that stimulation of the emetic reflex results in AVP-release in man. Nausea-mediated AVP release supervenes over concomitant osmolar or pharmacologic (ethanol) inhibition.

The intravenous (i.v.) administration of 4 mug/kg 6-deoxy-6-dihydroazido-isomorphine (6-AM) base to healthy, young adult male volunteers caused no circulatory and relatively little, short-lasting respiratory depression. Of the ten volunteers all felt lightheaded, two became euphoric and when they became ambulatory at the end of the experiment, three vomited and two other became nauseated. The intramuscular (i.m.) administration of the same dose of 6-AM had considerable analgesic effect against various types of experimental pain. It was more effective against ischemic pain, than against pain induced by electrical stimulation of the earlobe or the tooth pulp and it effected severe pain more than mild or moderate pain. In the six subjects investigated, 6-AM produced significant myosis. Of the 16 subjects who received 4 mug/kg 6-AM i.m. five experienced mild euphoria, two felt lightheaded, six became pale and sweaty in the course of the experiments carried out in the sitting position. When they becam ambulatory after the completion of the experiments, two subjects vomited and six others became nauseated. The findings of this study indicate that 6-AM causes less circulatory and respiratory depression than is to be expected from equianalgetic doses of morphine. Its other side effects (e.g., nausea, vomiting) are also less frequent and severe than those encountered after the administration of comparable doses of morphine to ambulating volunteers.

This study was carried out to determine if ethanol, which enhances theophylline absorption from the rat small intestine, has a similar effect when administered orally to human subjects. Seven normal adults received 200 mg of theophylline/m-2 of body surface area, in 50 ml of either aqueous solution or hydroalcoholic solution containing 20% ethanol. There was no significant difference in the average plasma concentrations of theophylline produced by these two solutions, but three subjects (all female) experienced nausea after taking the aqueous solution while none became nauseous after taking theophylline in the hydroalcoholic solution.

A case of lactic acidosis associated with phenformin therapy for diabetes mellitus is reported, and 34 previously reported cases of lactic acidosis associated with phenformin therapy are reviewed to determine if any predisposing factors to lactic acidosis were apparent. Observations of sex, age, duration of diabetes, pathologic conditions, dosage, duration of phenformin therapy and the onset of symptoms preceding lactic acidosis were made. Renal impairment, urinary tract infections, hepatic impairment, ethanol ingestion and poorly controlled congestive heart failure were found to be predisposing factors to lactic acidosis. The appearance of a syndrome of impending lactic acidosis consisted of anorexia, nausea, vomiting with abdominal pain or lethargy.

Clinical evidence suggests the possibility of conditioning of narcotic abstinence symptoms. Addicts report subjective and objective signs of withdrawal/craving when exposed to certain stimuli. This may partially explain the high rate of relapse to drug seeking behavior when treated addicts return to their home environment. Conditioning of narcotic abstinence symptoms was produced experimentally in five of eight volunteer subjects. Brief naloxone precipitated abstinence was the unconditioned response. The conditioned stimulus was a tone and odor. After an average of seven training trials, the tone and odor produced a conditioned abstinence response. The conditioned response consisted of subjective components (feelings of sickness, nausea, cramps, craving) and objective components (yawning, tearing, rhinorrhea, irregular respiration and transiently increased blood pressure). These laboratory findings support the anecdotal evidence regarding the existence of conditioned abstinence phenomena.
