Paroxetine is a new antidepressant drug with potent serotonin (5HT) uptake inhibitory properties. In this double-blind comparative study, the antidepressant effect of paroxetine and amitriptyline has been compared in 44 patients with depressive illnesses of an endogenous nature. Each drug was given for 6 weeks. The 17-item Hamilton Depression Scale was used to measure the antidepressant effect. Reported events were assessed applying a 22-item check list. Non-parametric statistical analyses were applied in the evaluation of treatment outcome for the 30 patients who completed the study. The results showed no significant differences in overall antidepressant efficacy between paroxetine and amitriptyline and that paroxetine displayed significantly fewer instances of dry mouth and orthostatic dizziness than amitriptyline. No obvious relationship was demonstrated between the plasma levels of the drugs and their clinical effects.

21 depressed patients of the Basle University Psychiatric Outpatient Clinic were treated in a double-blind study with paroxetine and amitriptyline. 11 of these patients did not continue the trial until the end of the 7th week. There was a significant difference in the number of dropouts between the two groups: 80% of the amitriptyline group did not continue until the end, while in the paroxetine group we found only 30% dropouts. The patients of both groups showed a gradual decrease of the median total scores on the Hamilton and the Montgomery and Asberg Depression Rating Scales. Although the number of patients who stayed in the trial for at least 4 weeks (8 with paroxetine, 6 with amitriptyline) is quite small, we see from the results of the clinical global impression that the members of the paroxetine group improved most of all in the somatic symptoms, while considering their moods we found no differences between the groups. Patients of both groups complained about side effects, most of all about dry mouth and tiredness. From the high rate of dropouts under amitriptyline we found that the side effects under this drug were more severe and therefore led to the dropouts.

We have studied 16 healthy men to evaluate preliminary pharmacodynamics and kinetics of BW443C given by i.v. infusions. Four volunteers received escalating doses at weekly intervals, starting at 0.1 microgram.kg-1 for 60 min and increasing to a maximum of 2.0 micrograms.kg-1.min-1 for 180 min. Subsequently 12 different subjects received single i.v. infusions of 10 micrograms.kg-1.min-1 for 20 min. Subjective effects were reported and objective measurements made of central nervous and cardiovascular effects. Blood was sampled at intervals on all occasions, plasma concentrations were determined by radioimmunoassay and pharmacokinetic profiles were analysed using NONLIN. Dry mouth and some nasal stuffiness were reported and postural hypotension occurred in 5/16 subjects at plasma concentrations greater than 0.8 microgram.ml-1. Supine blood pressure was well maintained in all subjects and hypotension resolved within 60-90 min of discontinuing the infusion. There was no evidence of sedation, mood change, nausea, vomiting, miosis, change in accommodation or respiratory depression. Rapid infusions produced transient feelings of warmth, heavy eyelids, heavy legs, and increased bowel sounds, which resolved despite increasing plasma concentrations. The disposition of the peptide was adequately described by a 2-compartment model with a mean +/- SD plasma clearance of 123 +/- 18 ml.min-1 and a half-life of 2.0 +/- 0.4 h.

One hundred consecutive patients, 74 women and 26 men, aged between 18 and 83 years (mean = 54.8 years), referred with complaints related to oral galvanism were investigated and treated and the treatment results were evaluated after 2-3 years. Forty of the patients reported facial pain, pain from the teeth, temporomandibular joints (TMJ) and masticatory muscles and TMJ clicking and locking and 26 reported headache. Smarting in the oral mucosa, smarting of the tongue and xerostomia were reported by 26, 21 and 24 patients, respectively, and 30 patients reported an unpleasant taste, a metallic taste or a battery taste. The same patient often reported several symptoms. The patients also reported various general symptoms, above all joint symptoms, pain in the back, neck and shoulders and general muscular pain but also tiredness, weakness, difficulty in concentrating, depression and insomnia. After clinical and radiological examination, salivary tests, determination of the maximum galvanic current at metallic contacts and screening for contact allergy to dental materials, various oral diagnoses could be established. Most of the patients exhibited functional disturbances of the masticatory system, periodontitis, smarting of the oral mucosa, xerostomia, pulpitis and pulpal necrosis and mucosal lesions. The medical illnesses the patients reported themselves to be suffering from or had been treated for included cardiovascular disorders, high and low blood pressure, asthma, rheumatic disorders, diabetes, pernicious anaemia, gastritis and peptic ulcer. Seventy-six patients took drugs regularly. In most cases there were several oral, dental and medical explanations for the symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)

During the last seven years 65 patients with Gilles de la Tourette's syndrome have been treated. Pimozide was used as the preferred drug because of our experience of treating other hyperkinesias which indicated fewer side-effects than with haloperidol. Of the 65 patients with Gilles de la Tourette's syndrome, 59 were treated with pimozide alone or in combination with tetrabenazine or clonidine. The dose ranges of pimozide were 0.5-9 mg per day. Eighty-one percent experienced a good clinical response without side-effects. The side-effects seen in our patients were sedation, gain in weight, depression, pseudoparkinsonism and akathisia; acute dystonic reactions, blurred vision, slurred speech and xerostomia did not occur. No cases of tardive dyskinesia were seen.

Clonidine and doxepin alleviate the symptoms of the opiate withdrawal syndrome. Clonidine was slightly more effective in controlling sweating, hot flushes, palpitations and nausea, and doxepin was slightly more effective in relieving the craving for opiates, lassitude and depression. Adverse effects such as sedation, dry mouth and falls in blood pressure occurred in both groups. There were six cases of collapse during treatment with high doses of doxepin, whereas only one subjective circulatory effect occurred in the clonidine group. At these high doses, doxepin may cause orthostatic hypotension via a peripheral alpha-receptor blockade. Clonidine reduced pulse rate whereas doxepin, with its anticholinergic action and indirectly via its alpha-receptor blocking action, raised it. Several patients in the doxepin group hat fits, as opposed to only one in the clonidine group. It is possible that the use of barbiturates had reduced the convulsive threshold in some of our patients. Overall, clonidine and doxepin were equipotent at adequate individual dose levels, and both were well tolerated. In this trial, serious side-effects occurred less often in the clonidine group.

Tricyclic antidepressants are among the commonest causes of both non-fatal and fatal drug poisoning in the world. Their toxicity is due to effects on the brain, the heart, the respiratory system and the parasympathetic nervous system. Symptoms usually appear within 4 hours of an overdose and all but the most seriously poisoned patients recover within 24 hours. The most common clinical features are dry mouth, blurred vision, dilated pupils, sinus tachycardia, pyramidal neurological signs, and drowsiness. In severe poisoning, there may be coma, convulsions, respiratory depression, hypotension and a wide range of electrocardiographic (ECG) abnormalities. The most frequent findings on the ECG are prolongation of the PR and QT intervals; the tracing may resemble bundle branch block or supraventricular or ventricular tachycardias. Treatment of poisoning due to the tricyclic antidepressants is essentially supportive, there being insufficient evidence at present to recommend the use of methods to increase elimination of the drug from the body. Gastric aspiration and lavage should be performed if more than 750 mg of drug have been taken. There must be regular monitoring for hypoxia, acidosis and hypokalaemia and these complications should be corrected enthusiastically. Convulsions should be treated with diazepam or chlormethiazole. Muscular paralysis and artificial ventilation should be employed if anticonvulsants are ineffective. Hypotension should be treated firstly by fluid replacement and then with sympathomimetic agents (dopamine or dobutamine). Antiarrhythmic drugs should only be employed if there is evidence of circulatory failure which fails to respond to correction of hypotension. Sodium bicarbonate infusions should be given to cardiotoxic patients who are acidotic and are worth trying even if the patient is not acidotic. Although physostigmine salicylate will reverse most of the features of tricyclic antidepressant poisoning, its effects are short-lived in serious toxicity and it can produce dangerous side effects; physostigmine should therefore be reserved for those patients who have complications of coma or who have resistant cardiotoxicity or convulsions. Drug screening and quantitative determination of tricyclic antidepressant serum concentrations are useful in a minority of patients who have severe, unusual or prolonged symptoms.

In a double-blind randomized study the therapeutic effect and safety of alprazolam was compared with amitriptyline in 81 outpatients suffering from major depression. Variable dosages of both drugs were used, the mean final dose of alprazolam being 3.05 and that of amitriptyline 130 mg. Both treatment groups improved steadily, assessed weekly with the use of the Hamilton Rating Scale for Depression, and no significant differences were found between the groups, either on comparison between single items or total scores. On several of the criteria used for assessment of treatment response, however, more patients responded to amitriptyline than to alprazolam. In an analysis of specific subgroups, patients whose depression was accompanied by retardation, those in whom there were no precipitating factors and those with low levels of anxiety, responded better to amitriptyline. Considerably fewer side effects were reported by patients receiving alprazolam. In particular, there was a significantly lower incidence of dry mouth, light-headedness, tremor and tachycardia in patients receiving alprazolam compared with amitriptyline.

Forty-two outpatients with major depressive disorder were treated with oral fezolamine in a 6-week, three-center open-label study. Therapy was initiated at 100 mg/day; thereafter dosage was increased based on the response of the patient. Maintenance dosage usually ranged between 100 and 450 mg/day. Clinically significant improvement relative to the patient's prestudy state was observed after 2 weeks in both patient and physician-rating scales. Fifty-five percent of patients improved their Hamilton Psychiatric Rating Scale for Depression (HAM-D) scores by more than 50%. The median dose associated with a clinically significant response was 245 mg/day. Five of the 6 patients who dropped out did so because of gastrointestinal adverse effects. The most common adverse effects were nausea (36%), headache (29%), constipation (26%), and dry mouth (24%).

The efficacy and safety of fluoxetine, a new antidepressant agent, were assessed in a double-blind, parallel, randomized study of 44 outpatients with major depressive disorder. Following a 1-week placebo period, patients were randomly assigned to either fluoxetine or amitriptyline for a period of 5 weeks. The mean maintenance dosages were 55 mg/day for fluoxetine and 159 mg/day for amitriptyline. Both drugs were effective in relieving the symptoms of depression. The most frequently reported side effects were nausea and nervousness for fluoxetine, and dry mouth, dizziness, and drowsiness for amitriptyline.
