The antidepressant effects and side effects of mianserin and maprotiline were assessed in a double-blind trial in 62 inpatients (34 men and 28 women; mean age, 43.6 years) with primary depressive illness. For the first week of the trial, 32 patients received 30 mg/day of mianserin and 30 patients received 75 mg/day of maprotiline; for the next three weeks, the dosage of each drug was doubled. According to scores on the Hamilton Psychiatric Rating Scale for Depression, administered on days 0, 7, 14, 21, and 28, the antidepressant effects of the two drugs were virtually identical. Results of electrocardiographic and vectorcardiographic recordings and other measurements indicated that by day 28 the QRS duration was significantly longer (P less than 0.05) in the maprotiline group. On days 14 and 28, mean systolic blood pressure was significantly higher (P less than 0.05) in the maprotiline group. By day 28, the incidence of anticholinergic side effects--constipation and dry mouth--was significantly higher (P less than 0.05) in the maprotiline group. Although maprotiline's effects on heart functions never reached clinical significance, its anticholinergic side effects could be bothersome, especially to older patients.

Sixty out-patients with different nosological types of depression were assigned at random to three different treatment groups and were treated under double-blind conditions for 6 weeks. Two groups received diclofensine in capsules of either 15 or 25 mg, and a third group received capsules with imipramine 25 mg. The dosage schedule provided an initial dose of 2 capsules/day which was to be gradually increased up to a maximum dose of 9 capsules/day. The daily mean dosages actually given over the entire trial period were 64.0 mg diclofensine for group I, 97.6 mg diclofensine for group II, and 102.9 mg imipramine for group III. All treatment groups showed a good improvement of the patients' clinical states within the 6-week period, but the imipramine-treated patients improved more slowly than the diclofensine-treated patients. This was demonstrated by the mean total scores of the Hamilton Depression Rating Scale (HDRS). Evaluation of different factors of the HDRS yielded differences between the two drugs in favour of diclofensine for the factor 'inhibition' from the end of week 1 until the end of week 3 and for the factor 'somatic complaints' during week 3. Side effects were - dose dependently - less frequent, less severe, and lasted shorter in the diclofensine-treated patients than in the imipramine-treated ones. The most frequently reported side effects in the diclofensine-treated patients were dry mouth, insomnia, dizziness, and agitation. In the imipramine group side effects were mainly dry mouth, tremor, dizziness, and sleepiness. In conclusion, this study shows an impressively faster onset of efficacy of diclofensine over imipramine, a finding which should be replicated by further studies.

The present study examined the effects of various substances on salivary secretion in 25 psychiatric inpatients suffering from depression or schizoprenic disorders. It is well known that tricyclic neuroleptics and anti-depressants lower the rate of salivary excretion and lead to hyposalivation and a dry mouth. The following methods were studied on their effect to compensate hyposalivation: Distigminbromid, sweets, Glandosane, a new synthetic saliva, and water which was gustatory adopted. Salivary flow was measured according to Matzker (7). Subjective feelings of thirst and mouth dryness were recorded by selfconstructed tests. Only Glandosane and Distigminbromid compensated mouth dryness. The recorded amount of salivary flow was within the range of normal controls. There were no significant correlations between the subjective test answers and the objective measurement of salivary rate. Improvement of depression by application of Glandosane could not be observed. Patients treated with Glandosane felt most comfortable whereas in those treated with Distigminbromid side effects as digestive disorders, urinary disorders and changes in perspiration were observed.

Alprazolam is a triazolobenzodiazepine, a derivative of the benzodiazepines. Comparison studies of alprazolam and diazepam or chlordiazepoxide in patients suffering from clinical anxiety secondary to anxiety neurosis or chronic alcohol withdrawal suggest an equal efficacy of those agents. Studies examining the use of alprazolam for the treatment of "primary depression" suggest that it is as effective as imipramine in the treatment of exogenous (reactive) depression. Although alprazolam may be effective in patients with exogenous depression, no extrapolation can be made to the treatment of endogenous depression. Mechanisms of action have not been fully elucidated, but probably are similar to those of other benzodiazepines. Peak blood levels are reached in 0.7-1.6 hours and the elimination half-life after steady state is approximately 19 hours. Daily dosages established from clinical studies ranged from 1 to 6 mg. Clinically, alprazolam appears to be ten times more potent than diazepam. Drowsiness, headaches, lightheadedness, dry mouth, and depression appear to be the most common side effects of the drug. It is concluded that alprazolam offers no striking therapeutic advantage over currently marketed benzodiazepines.

Fifty-six surgical patients self-administered i.v. narcotic analgesics to combat postoperative pain. Analgesic demand per h was 2.7 +/- 1.1 mg of morphine, 26 +/- 10 mg of pethidine or 2.3 +/- 0.8 mg of ketobemidone, which reflects the equianalgesic ratios. Acute respiratory depression was seen in two hypovolaemic patients as evidenced by a raised PaCO2 on air breathing. Carbon dioxide retention disappeared upon correction of hypovolaemia. Late respiratory complications of short duration were encountered in 13%. Drowsiness and dry mouth were the most frequent complaints. Self-administered analgesia was considered highly satisfactory by the patients.

Tricyclic antidepressants (for example, amitriptyline) and other types of antidepressants (for example, amoxapine and maprotiline) are competitive antagonists of muscarinic acetylcholine receptors, the predominant class of acetylcholine receptors in the brain. Some evidence suggests that this muscarinic receptor blockade in brain alleviates depression. However, all tricyclic antidepressants appear to be equally effective in treating depression despite having differences in their antimuscarinic potencies while having similar ranges of therapeutic blood levels. It is more likely that the antimuscarinic potency of antidepressants is related mainly to the frequency with which they cause such symptoms as blurred vision, dry mouth, and urinary retention. Information on the antimuscarinic potency and other receptor-blocking potencies of antidepressant agents can be helpful in minimizing or avoiding certain side effects when these drugs are given to patients.

In a 4-week double-blind study comparing alprazolam with diazepam treatments, 48 outpatients suffering from mild to moderate generalized anxiety were evaluated after a 5-day placebo washout, and then after 1, 2, and 4 weeks of treatment. The optimal therapeutic doses without excessive sedation averaged 2 mg for alprazolam and 15.8 mg for diazepam. Results from the Hamilton Anxiety Rating Scale, the Clinical Global Impression Scale, a behavior checklist questionnaire, and a symptomatic patients' self-rating scale indicated that patients improved in both treatment groups. Results from the comparative phase suggest that diazepam is more efficient than alprazolam in the reduction of several symptoms of anxiety and depression in particular. Assuming that the first 2-week ratings depend on accuracy of dose adjustment and that week 4 ratings are an important evaluation of long-term efficacy, results from this study suggest that adequate control of anxiety is obtained more readily with diazepam and that symptoms of depression might benefit more from that drug. Few side effects were reported: mainly, drowsiness, tremor, light- headedness , and dry mouth. A toxic reaction to alprazolam, possibly allergic, was observed. Either alprazolam or diazepam appeared to be effective in the treatment of generalized anxiety disorder, and the statistically significant differences between the two drugs were not clinically striking.

Halazepam is a new benzodiazepine derivative that is molecularly similar to chlordiazepoxide and diazepam. Animal studies indicated that halazepam produces sedative and antianxiety effects with less toxicity than chlordiazepoxide or diazepam. Computer EEG and somatosensory evoked potential studies demonstrated that halazepam has a significant effect on the EEG, characteristic of changes that occur with benzodiazepines. In initial clinical studies, halazepam exhibited not only anxiolytic properties but also reduced symptoms of depression and had a therapeutic effect on epilepsy. In preliminary, uncontrolled clinical trials, halazepam was effective in ameliorating anxiety and tension in alcoholic and acute schizophrenic patients, with few adverse effects. Later double-blind studies generally demonstrated that halazepam is significantly superior to placebo in alleviating symptoms of anxiety and tension. Most comparative studies indicate that halazepam is equal to or more effective than diazepam with a lower frequency of side effects. Halazepam does not increase hostility and aggression, as chlordiazepoxide and diazepam have been shown to do, and it is effective in both situational and characterologic anxiety. Drowsiness and slight dry mouth are the only side effects reported in more than isolated instances, although geriatric patients may frequently become ataxic with higher doses.

A double-blind, randomized clinical study was conducted in thirty-four out-patients suffering from major depressive disorders comparing zimelidine with amitriptyline. The dosage was flexible, maintenance doses varying between 50-150 mg in the amitriptyline group and 50-300 mg in the zimelidine group. After a wash-out period of at least a week the mean score in Hamilton Rating Scale for depression (HRS) was 22.2 for zimelidine and 21.9 for amitriptyline. During the treatment period of 6 weeks, zimelidine and amitriptyline appeared to be equally effective as antidepressants in HRS and Global Ratings. The zimelidine group showed significantly less somnolence and dry mouth. No clinically important changes were seen in the laboratory parameters during the study.

Paroxetine, a new, potent and selective serotonin (5-HT) uptake inhibitor has been evaluated in an open study for its clinical effect as well as its effect on the 5-HT concentration in whole blood in 19 patients with depressive illness. Paroxetine was administered in daily doses of 20 to 60 mg. The global evaluation after six to eight weeks showed a marked improvement in 11 patients, a moderate improvement in four and no change in four patients. Assessment with the Hamilton Rating Scale for Depression in ten patients showed a reduction from a mean score of 22.7 to 6.6 in six weeks. Maximal reduction was, however, first seen in three of the patients after 8 to 12 weeks. No correlation between the antidepressant effect and plasma concentrations of paroxetine was found. The only side effects noted with paroxetine were that two patients complained of dry mouth in the beginning of the treatment and a further patient experienced a burning sensation together with periodical light headache. Generally laboratory examinations did not show any trend towards pathological values except in one patient, where a moderate leucopenia was observed. Crista puncture/biopsy showed, however, no specific bone marrow reaction. The 5-HT concentration in whole blood was reduced to about 0.02 micrograms/ml indicating a total depletion of 5-HT from the thrombocytes. The present study indicates that paroxetine possesses a good antidepressive effect in combination with a very low frequency of side effects.
