All tetracycline preparations seem to be systemically effective in acne. Quality and frequency of their side-effects, however, are different and should be carefully considered in each individual case. In an own study ninety-one patients treated with minocycline showed good response in 69% and moderate or no response in 31+. The main side-effects of the drug were nausea and giddiness, being of short duration in most cases. In patients with no response to a certain preparation change of the preparation may be helpful. Occasionally, acne does not respond to any tetracycline derivative. In these cases the use of non-tetracycline antibiotics, particularly of trimethoprim-sulphamethazol and lincomycines, is clearly effective. As a rule, we start treatment with tetracycline (500-750 mg/d) and reduce the dose to a minimum (ca. 100 mg/d), in order to withdraw the drug. In non-responsive cases another derivative and/or finally non-tetracycline antibiotics are administered for therapy.

A prospective double-blind study was performed to compare metoclopramide (Primperan) with morphatropin in the treatment of ureteral colic. Twenty-one patients (10 in the morphatropin group and 11 in the metoclopramide group) entered the study and diagnosis was confirmed radiologically. Using the Mann-Whitney rank sum test, no significant difference was found in the pain-relieving effect 10, 20, or 30 min after treatment with either 1 ml morphatropin s.c. or 20 mg metoclopramide i.v. Two patients in the morphatropin group developed nausea and giddiness, respectively, and 1 patient from this group was omitted due to the development of urticaria. No side effects occurred in the metoclopramide group. Thus metoclopramide seems to be an alternative to the traditional treatment of ureteral colic with morphia.

We did a double blind, crossover, prospective study comparing bicarbonate and acetate containing solutions in haemodialysis. Thirty stable patients with end stage renal disease on maintenance haemodialysis while awaiting a renal transplant were each studied on three dialysis with acetate and three with bicarbonate. Nine patients developed symptoms like headache, nausea, vomiting, giddiness, and malaise and developed hypotension during acetate dialysis and three patients during bicarbonate dialysis. There were symptoms during 16.66% of acetate dialysis sessions and 5.55% of bicarbonate dialysis sessions. (P less than 0.05). There was a statistically significant decrease in PaO2 and PaCO2 on acetate dialysis at 30 minutes after initiation of dialysis. There was no significant difference in weight loss on dialysis, or in blood pressure and correction of acidosis. We conclude that bicarbonate dialysis is better tolerated, but acetate intolerance is not a major problem since we use small surface area dialysers (0.8 M2).

The authors' findings permit a conclusion that the risk of ethmozine overdosage leading to undesirable side effects (dryness in the mouth, noise in the ears, a 'net' in eyes; giddiness, nausea, vomiting) is very high when routine ethmozine doses are administered to patients with grave (Stages II-III) impairments of liver function; this is explained by (1) reduced rate of ethmozine biotransformation, this resulting in a heightened concentration of the drug in the blood, and (2) by an increase of the drug free fraction concentration due to its reduced ability to bind with the blood plasma proteins. This necessitates a pharmacokinetic monitoring of such patients prescribed ethmozine and a correction of the drug dose, if necessary.

Buspirone is an antianxiety compound that has been extensively evaluated in clinical trials: it has proved superior to placebo and comparable to diazepam in the treatment of patients with generalized anxiety disorder. In this study, 33 outpatients with generalized anxiety disorder were entered into a crossover study of 3 weeks each of placebo, buspirone 10 to 30 mg daily, and diazepam 10 to 30 mg daily. Psychiatrist and patient ratings were made, together with psychological tests and EEG and skin conductance measures before and after each treatment. Of the nine dropouts, six were on buspirone at the time of dropout. For the remaining 24 patients, the mean daily doses attained of buspirone and diazepam were both 20 mg. On most clinical ratings diazepam was superior to buspirone and placebo, which did not differ. Diazepam produced minor psychomotor changes and the expected major effects on the EEG. Buspirone was without effect. Side effects on buspirone were mainly nausea and giddiness and on diazepam, drowsiness. The lack of efficacy of buspirone is discussed in terms of the previous benzodiazepine exposure--23/24 patients had had previous exposure and only 10 were able to tolerate a pretrial placebo washout period. The implications are considerable for the introduction of any new antianxiety agent not cross-tolerant with the benzodiazepines into a chronically anxious group of patients with previous long-term benzodiazepine therapy.

Primidone was compared to the unselective beta adrenoceptor antagonist propranolol in the suppression of essential tremor. In a 4-week single-blind placebo-controlled study primidone was given in increasing doses from 62.5 mg X 1 up to 250 mg X 3 daily and propranolol 20 mg X 3 daily. The drugs produced a similar reduction in the degree of tremor after 2 and 1 weeks' medication respectively. This indicates that primidone can be an alternative to propranolol when beta-blockers are contraindicated. However, primidone was significantly even more effective in the beginning after only 2 doses, when at the same time 10 of 13 patients showed a maximum of acute toxic side-effects producing nausea, vomiting, giddiness and/or sedation. Correlation analysis between the individual tremor amplitude reductions and plasma primidone concentrations showed on the second day a tendency towards a greater reduction in tremor in those patients with the highest primidone plasma concentration. By the fourteenth day tremor had increased compared with the second day and correlation analysis between individual increase in tremor amplitude and plasma phenobarbital concentrations showed the highest degree of tremor increase in those patients who had the highest levels of phenobarbital. These and other data suggest that after the first doses, tremor suppression and acute toxicity is related to the initial exposure to primidone and the plasma level of the drug itself rather than its metabolites phenobarbital and phenylethylmalanomide. The individual tremor frequency spectrums did not change significantly during the placebo and propranolol periods, whereas the frequency tended to decrease during the primidone period.

In a field study conducted in Burma, 54 semi-immune adults suffering from falciparum malaria (mean parasite count, 15 328/mm(3) before treatment) were given a single dose of a fixed combination of 750 mg mefloquine base, 1500 mg sulfadoxine, and 75 mg pyrimethamine (3 tablets of Fansimef). All these patients were cleared of asexual parasites by day 7, giving a cure rate of 100%; the mean clearance time was 2.6 days. Reappearance of parasitaemia occurred in 10 patients on or before day 7 and persisted for one day in 8 of them and for two days in 2 patients. It eventually disappeared without further treatment. No recrudescence occurred during the follow-up time of four weeks despite the fact that there was active transmission of Plasmodium falciparum in the area throughout the whole of the study period. The drug was generally well tolerated, though mild to moderate giddiness was reported by 49 patients (90.7%) and severe giddiness by 3 patients (5.5%). Nausea occurred in 25 patients (46.3%) and vomiting in 17 (31.5%).

In a double-blind placebo-controlled cross-over study the encephalotropic and psychotropic properties of sertraline--a new potent and highly selective inhibitor of synaptosomal serotonin uptake--were studied along with blood levels of the parent drug and main metabolite in ten normal healthy volunteers. They received randomized at weekly intervals oral single doses of placebo, 100, 200 and 400 mg setraline and 100 mg zimelidine as reference drug. Blood sampling, EEG recordings, psychometric tests and evaluation of pulse, blood pressure and side-effects were carried out at the hours 0, 2, 4, 6, and 8. Blood level investigations demonstrated that sertraline is slowly absorbed with dose-dependent blood concentrations peaking in the 4th to 6th hour and remaining high thereafter, while the main metabolite, CP-53261 exhibited an even slower rise in plasma concentration up to the 8th hour. Computer-assisted spectral analysis of the EEG demonstrated slight effects of 100 mg zimelidine and 100 mg sertraline on human brain function, but moderate to marked effects after 200 and 400 mg sertraline as compared with placebo. Changes after 100 mg sertraline and the reference compound resembled the pharmaco-EEG profiles of antidepressants of the desipramine type and were indicative of some vigilance-improving properties while higher doses of sertraline induced alterations reminiscent of those after antidepressants of the imipramine type, thereby reflecting vigilance changes of the dissociative type. This neurophysiological conclusion was supported by the psychometric and psychophysiological data showing partly after 100 mg sertraline and zimelidine an improvement in psychometric performance, while 200 and 400 mg sertraline induced a deterioration of noopsyche and thymopsyche of the normal volunteers. Psychophysiological variables exhibited a dose-dependent change in CNS activation and a widening of the pupillary size. Time-efficacy calculations based on pharmacodynamic changes demonstrated maximal encephalotropic effects after 100 mg zimelidine in the 2nd to 4th hour, and after setraline in the 4th to the 6th hour, which is in agreement with the blood level data. Pulse, systolic and diastolic blood pressure showed no clinically relevant findings. Side-effects were non-existent to minimal after 100 mg zimelidine and sertraline, but marked after 200 and 400 mg sertraline characterized by nausea, vomiting, diarrhea, giddiness, restlessness, tremor and trismus.

Norfloxacin, a new oral quinolone, was compared with intramuscular spectinomycin for treating culture proved gonorrhoea (caused by penicillinase producing strains of Neisseria gonorrhoeae (PPNG) and non-PPNG strains. A total of 547 infected men and women were randomly allocated to treatment with either single dose norfloxacin (800 mg by mouth) or spectinomycin (2 g intramuscularly). Patient preference for tablets or injections was noted at this visit. Patients returned four to eight days later for assessment of efficacy, safety, and preference. Of the 482 patients who attended follow up, all those treated with norfloxacin (94 infected with PPNG strains, 145 with non-PPNG strains) and all 82 infected with PPNG strains and treated with spectinomycin were cured. Of 161 infected with non-PPNG strains and treated with spectinomycin, 159 (99%) were cured. Side effects (headache, nausea, and sleepiness) occurred in three patients receiving norfloxacin and in 17 (16 pain at injection site, 1 giddiness) receiving spectinomycin. Most patients preferred tablets to injection both on day 1 (313 v 200) and at follow up (373 v 104). This study showed that norfloxacin was a highly effective alternative to spectinomycin, produced fewer side effects, and was the preferred mode of administration.

Thirty-two workers in an electroplating plant accidently drank water contaminated with nickel sulfate and chloride (1.63 g Ni/liter). Twenty workers promptly developed symptoms (e.g., nausea, vomiting, abdominal discomfort, diarrhea, giddiness, lassitude, headache, cough, shortness of breath) that typically lasted a few hours but persisted 1-2 days in 7 cases. The Ni doses in workers with symptoms were estimated to range from 0.5 to 2.5 g. In 15 exposed workers who were tested on day 1 postexposure, serum Ni concentrations ranged from 13 to 1,340 micrograms/liter and urine Ni concentrations ranged from 0.15 to 12 mg/g creatinine. Ten subjects (with initial urine Ni concentrations greater than 0.8 mg/g creatinine) were hospitalized and treated for 3 days with intravenous fluids to induce diuresis, resulting in a mean elimination half-time (T1/2) for serum Ni of 27 hours (SD +/- 7 hour), which was significantly shorter (p less than .001) than the mean T1/2 of 60 hours (SD +/- 11 hours) in 11 subjects who did not receive intravenous fluids. Laboratory tests showed transiently elevated levels of blood reticulocytes (N = 7), urine albumin (N = 3), and serum bilirubin (N = 2). All subjects recovered rapidly, without evident sequellae, and returned to work by the eighth day after exposure.
