In a double blind placebo-controlled cross-over trial of 24 weeks 31 patients with Raynaud's syndrome were treated with the alpha-blocker phenoxybenzamine (10-20 mg daily) and with the combination of the alpha-blocker phenoxybenzamine (10-20 mg daily) and the beta-blocker sotalol (40-80 mg daily). A favourable effect on recovery of finger temperature after finger cooling was demonstrated after alpha-blockade as compared to the before treatment situation. This favourable effect was not different when the group received the combined alpha- and beta-blockade. The blood pressure was not influenced by either of the 2 medications. Fluid retention appeared with alpha-blockade and was absent with combined alpha- and beta-blockade. Decrease of heart rate occurred with alpha- plus beta-blockade and was absent with alpha-blockade alone. Clinical symptoms of Raynaud's syndrome equally were alleviated by the two medications. Common, and equally frequent side effects of the two medications were nasal congestion, disturbed ejaculation and potency, dry mouth, exercise-induced and orthostatic dizziness. We conclude that alpha-blockade is beneficial in Raynaud's syndrome and that additional beta-blockade counteracts the alpha-blocker side-effect fluid retention, reduces the heart rate and thus may prevent alpha-blocker induced tachycardia, and that it does not cause hypotension.

Twelve parallel, open, uncontrolled therapeutic studies on 3-fluoro-6-(4-methyl-piperazinyl)- 11H -dibenz[b,e]azepine ( fluperlapine , NB-106 689) were performed as a multicenter trial using standardized protocol/case report forms and inclusion and global assessment criteria. 66% of 104 medium to severe acute or relapsed schizophrenic patients showed a very good or good overall benefit (responder rate 80%) with 200-400 mg fluperlapine daily, median 300; 20-1200 mg; 6 weeks. Ratings ( FSCL -NL = (Fischer Symptom Check List Neuroleptics, BPRS = Brief Psychiatric Rating Scale, FSUCL = Fischer Somatic Symptoms and Untoward Effects Check List) showed a quick onset of action (25% improvement in 5 days) and a very good improvement of all important and secondary single symptoms or symptom groups. FSCL -NL and BPRS were highly correlated (R = 0.87). Tolerability was very good or good in 88% of patients (very good in 65%, poor or bad in 12%), mild to moderate fatigue being the most prominent untoward effect (means 25% of patients, max. 31 per control) followed by dizziness, tremor, dry mouth (10%). No drug-induced Parkinsonism was seen. No recurrent or relevant abnormalities in relation to fluperlapine were observed in safety data (circulation, blood, kidney or liver function). Several times paroxysmal dysrhythmias/sharp waves were seen in the EEG, and in our studies 2 patients experienced epileptiform seizures of short duration after overdosage. In one patient showing a granulocytopenia before starting fluperlapine , an agranulocytosis was seen, which normalized quickly after stopping fluperlapine .

The aim of this study was to evaluate the safety of zimeldine, a 5-HT reuptake inhibitor, in the long-term treatment of depressive disorders. The study was an open label, multicentre investigation involving 147 patients who were suffering from depressive illness and who needed long-term anti-depressant treatment. Sixty-five patients completed the intended treatment period of 1 year, 75 terminated prematurely, and 7 are still in the programme. The reasons for termination were mainly ineffectiveness of the drug and adverse reactions. During the long-term treatment the most common emergent symptoms were, in order of decreasing frequency, dizziness, dry mouth, sleep disorders, sweating, tremor, nausea and headache. The side-effects were, however, mild and they generally decreased during the treatment period. No new adverse symptoms were reported. In the long-term treatment group, body weight showed a slight mean decrease. Clinical chemistry and cardiovascular investigations were judged to show no changes of clinical importance. It is concluded that zimeldine was shown to be a safe drug in this 1-year treatment programme of depression.

We compared the patient acceptance and efficacy of 60 mg extended-release fenfluramine and placebo before the evening meal in a 10-week, double-blind trial. All 51 participants were 130% to 180% of ideal body weight. They received instruction in diet and behavior modification for 2 wk before the beginning of and during the medication period. Mean weight loss was 5.9 kg (8.0 +/- 4.6% of initial weight) in the fenfluramine group and 3.3 kg (5.5 +/- 3.5%) in the placebo group. Fenfluramine-treated participants reported lower hunger ratings and greater fullness in the target supper-to-bedtime period than participants receiving placebo. Both groups reported dry mouth, dizziness, drowsiness, fatigue, and diarrhea. Although the fenfluramine group reported more complaints, these diminished to less than half after 2 wk of treatment. Four of the fenfluramine and three of the placebo group dropped out for drug-related reasons. In all, 10 fenfluramine and 8 placebo participants dropped out. Fenfluramine participants had a higher benefit score with no difference in risk scores. The fenfluramine group's global evaluation was better than that of the placebo group. Participants viewed the study and the dosing regimen positively but had negative ideas about anorexiants in general. Extended-release fenfluramine taken in the evening was well tolerated and maintained its efficacy as measured by standard and novel techniques.

Twenty cancer patients who received chemotherapy were entered into a double-blind crossover design antiemetic study comparing 1 mg levonantradol, an investigational synthetic cannabinoid, to 10 mg prochlorperazine. Sixteen patients completed the crossover. For each antiemetic course, four doses of each study medication were given intramuscularly 2 hours before chemotherapy and then 2, 6, and 10 hours after chemotherapy administration. There were no statistical differences in patients' responses to levonantradol and prochlorperazine. The frequency of side effects was greater with levonantradol than with prochlorperazine. The most common side effect of levonantradol were somnolence, dry mouth, dizziness, tachycardia, postural hypotension, and blurred vision, while those for prochlorperazine were somnolence, dry mouth, and tachycardia.

Three double-blind, placebo controlled studies found isocarboxazid (40-50 mg/day) to be efficacious and safe for the treatment of atypical depression. The few instances of liver function elevations were generally borderline; one patient had a marked increase of both SGOT and SGPT (with normal bilirubin and alkaline phosphatase) at Week 6 which normalized over the next several months. Another patient had a mild, temporary hypertensive reaction after eating cheese but did not require any treatment alterations. Drops in both systolic and diastolic blood pressures, as well as orthostatic changes, were common but generally mild and well-tolerated. The most frequently noted side effects were dizziness, headache, dry mouth, insomnia, and constipation. Clinical adverse reactions tended to be mild and to respond to dosage decreases. Isocarboxazid appears to be an underutilized and potentially valuable agent for the treatment of depressed patients.

A randomized study was carried out in 100 patients with acute tonsillo-pharyngitis to compare the effectiveness and tolerance of treatment with 500 mg spiramycin 3-times daily for 3 days and 500 mg erythromycin 3-times daily for 5 days. Details were recorded on entry of fever, sore throat, difficulty in swallowing, inflammation of the tonsils and/or pharynx, and oedema. Patients in the two groups were re-examined on Days 4 and 6, respectively. Throat swab cultures and blood determinations of haemoglobin, leucocytes and erythrocyte sedimentation rate were made before and after treatment. The results, analyzed in the 95 patients (48 on spiramycin, 47 on erythromycin) who attended for follow-up, indicated that whilst both antibiotics were effective, only 1 patient receiving spiramycin was classified as failing to respond to treatment compared with 8 of those receiving erythromycin. Moreover, significantly fewer patients on erythromycin had complete disappearance of all the signs and symptoms at the end of the treatment period. These findings were supported by the results of the bacteriological cultures. Both treatments reduced leucocyte levels in those patients with high counts initially, but there was no apparent effect on haemoglobin or erythrocyte sedimentation rate. Two patients on spiramycin complained of dry mouth. In the erythromycin group, 2 patients reported dizziness and 5 nausea.

1 The effects of fluvoxamine to a maximum of 300 mg daily were compared with those of imipramine to a maximum of 200 mg daily, in 151 patients with primary major depression. 2 Four weeks of treatment with fluvoxamine resulted in 67.2% improvement (+/- s.d. 21.6) on the Hamilton Rating Scale for Depression (26 items). Treatment with imipramine showed 62.1% improvement (+/- s.d. 29.5) on this scale. 3 Fluvoxamine had no untoward effects on the cardiovascular system, while imipramine produced systematic increases in the postural fall in blood pressure. Dry mouth, nausea, daytime somnolence and tremor were seen with fluvoxamine treatment, while imipramine was associated with dry mouth, daytime somnolence, dizziness and tremor. 4 We conclude that fluvoxamine seems to have the same general antidepressant efficacy as imipramine. It was not associated with any safety problems and was generally well tolerated.

Outpatients with endogenous depression diagnosed according to the research diagnostic criteria of Feighner et al. were randomly referred to treatment with zimelidine (100 mg b.i.d., group Z) or maprotiline (75 mg b.i.d., group M). Patients who did not respond to treatment by days 28 were crossed over to the other drug. This preliminary report comprises results up to day 28 and includes antidepressive effect as rated by CPRS and globally, side effects, clinical chemistry and ECG. Ratings were double-blind at days 0, 7, 14 and 28, and a washout period of 4--7 days preceeded the trial. Group Z includes 27 and group M 28 patients with equal distribution of sex, age, duration of present episode, initial severity, etiology and previous course. There were 11 dropouts in group M and 5 in group Z due to side effects or treatment failure. On the other hand, 8 patients in group Z had to cross over to the other drug versus 2 in group M. According to the total CPRS score and the global score the antidepressive effect was somewhat better in group Z at 2 weeks but similar at 1 and 4 weeks. Group Z is less sedative but still seems to have a better anti-anxiety effect. Side effects were on a low level. There was a greater number of patients in group Z who complained of nausea, vomiting, loose stools, sleep disorder and sweating, and in group M dry mouth, drowsiness, dizziness and accomodation difficulties. Chemical analyses and ECG showed slight and inconsistent changes.

The clinical significance of intramuscular premedication with 0.01 mg/kg of atropine in a procedure involving oral benzodiazepine premedication (15 mg midazolam the evening before surgery and on the morning of surgery) was investigated in a double-blind study. As far as sedation, apprehension, excitement, dizziness, emesis, and headache were concerned, there were no significant differences between group 1 (atropine) and group 2 (placebo) patients; however, both during and after anesthesia patients in group 1 had less excessive salivary secretion (especially during extubation). As a result of sympathetic overactivity, patients in group 1 had an increased heart rate and an increased incidence of supraventricular tachycardia. In group 1 intravenous infusion proved more difficult, and in addition, the patients complained more of subjective side effects (dry mouth). There was no significant correlation between the radioimmunologically measured serum concentrations and the clinical effects of atropine measured just before the induction of anesthesia. Substantial interindividual differences were found in these serum levels. From the anesthetist's viewpoint, atropine has both beneficial effects (antisecretory) and unwanted effects (cardiovascular effects). For the patient atropine caused only subjective unwanted effects. Midazolam, a new short-acting, sedative benzodiazepine derivatives, can be used without atropine as an oral premedicant.
