Eleven hypertensive patients in whom clonidine therapy had to be discontinued, were treated prophylactically with labetalol, in order to avoid a possible hypertensive crisis. Most of the known side effects, which are consistent with the withdrawal phenomenon were observed, e.g. tremor, insomnia and apprehension, but headaches and flushing did not occur. Blood pressure levels remained unchanged, despite up to a 20-fold increase in plasma catecholamines. The lack of change in serial measurements of plasma cyclic AMP level appears to indicate that adequate adrenergic blockade was induced by labetalol. Since labetalol is a potent anti-hypertensive drug, and is also effective in avoiding a possible hypertensive crisis due to withdrawal of clonidine, we propose to use it as the drug of choice whenever discontinuation of clonidine therapy is indicated.

Tiapride was used in 55 chronic alcoholics. It has a sedative effect on the anxiety, aggressiveness and agitation observed during the alcohol withdrawal syndrome. It is also effective against tremor, insomnia and fatigue. Fatigue or depression do not occur as side-effects. Tiapride induces a psychological feeling of wellbeing which is heightened by continuation of detoxication and general management.

The effectiveness of tiapride on psychic disorders was studied in 30 chronic alcoholics by assessing four parameters: sleep disturbances, mood disorders, conduct disturbances, and tremor. In a daily dosage of 600 to 900 mg tiapride proved particularly effective on insomnia, anxiety, passivity and tremor, without adverse side-effects. This drug seems useful for controlling psychic disorders in alcoholics and for motivating acceptance of a detoxification program.

The efficacy of chlordiazepoxide and tiapride in the management of acute alcohol withdrawal syndrome was compared in a randomized, parallel-group, double-blind trial. The mean daily dose for both preparations on the first two days was four capsules, i.e., 200 mg for chlordiazepoxide and 400 mg for tiapride. Thereafter the patients were treated according to the relief of symptoms obtained. The treatment periods lasted 3-5 days. Both drugs effectively alleviated alcohol withdrawal symptoms, especially anxiety, fear, hallucinations, insomnia, sweating, tremor, abdominal pain and vertigo. Seventy percent of the patients in the chlordiazepoxide and 42% in the tiapride group considered the drug effective. The difference was statistically significant in favour of chlordiazepoxide (p less than 0.05). Tiapride is an alternative drug in the treatment of this condition, if benzodiazepines are to be avoided.

A total of 26 patients were treated with pergolide mesylate, a semi-synthetic ergot derivative with the property of direct dopamine activity. Of these patients, 18 suffered from late failure of L-dopa, while the remaining 8 had never before been treated with L-dopa. The aim of the trial was to study the activity of pergolide, either by giving it to untreated patients or by reducing as much as possible the L-dopa given in patients with parkinsonism. Adverse effects and failure rate were reduced by slowly increasing the daily dosage, by giving considerable dose flexibility whenever side-effects were manifest, and by the use of relatively low doses (mean of 3.8 mg in the L-dopa-group and 2.9 in the other group). At present, from 26 patients, 13 (50%) still remain in the study for an average treatment period of 16 months (3 weeks to 25 months for the group as a whole). All patients experienced a beneficial effect from pergolide, especially during the first months of treatment, in selfcare, rigidity, gait and automatic movements. Slight or no improvement was seen in tremor, speech and posture. The most frequent side-effects were nausea and vomiting (in the initial phase of the treatment), insomnia and psychotoxic reactions (mostly periods of confusion accompanied by visual hallucinations and paranoid illusions). The study indicated that pergolide mesylate is a useful additive for treatment of parkinsonism, but special attention should be paid to the important psychotoxic adverse effects that may appear, even at a low dose.

With the increasing use of amiodarone, several unwanted effects have been recognized. We reviewed 140 patients treated with amiodarone over a 5-year period in an attempt to identify patients at risk, to assess the incidence of these effects and their possible relation to dose, and to determine their outcome. The most common effect was photosensitivity (57% of patients responding to a questionnaire), whereas asymptomatic corneal microdeposits were found in all patients undergoing ophthalmologic examination. In contrast, symptomatic eye changes (colored halos) and slate-gray skin pigmentation were rare. Of the metabolic alterations, the rise in hepatic enzymes correlated with dose and plasma drug and metabolite concentrations (r = 0.59, p less than 0.001; r = 0.62, p less than 0.001, respectively) but was not associated with clinical disease. This relation to dose was not evident in patients developing clinical thyroid abnormalities (two hypothyroidism, two hyperthyroidism), all of whom had normal thyroid function prior to therapy. Four of the five hypothyroid patients were over 70 years of age. No patients developed peripheral neuropathy, but tremor and sleeplessness were common complaints (30% and 28% of patients, respectively) that responded to a decrease in dose. One patient with an abnormal chest x-ray film prior to therapy developed pulmonary fibrosis. We suggest the restricted use of high doses of amiodarone for protracted periods. Patients at particular risk are the older age group (hypothyroidism) and those with abnormal lung function prior to therapy who may be predisposed to pulmonary alveolitis. Most of the observed unwanted effects resolve when amiodarone is decreased in dose or discontinued.

The efficacy of metaproterenol (orciprenaline) and theophylline given orally at currently recommended doses was examined in 34 children with chronic asthma using a randomized double-blind cross-over evaluation of four weeks' duration for each active regimen. No serious adverse effects were seen with either medication, but tremor occurred more frequently with metaproterenol (P less than 0.01). No significant differences were observed in the frequency of nausea, vomiting, headache, or insomnia (P greater than 0.05). Symptoms of wheezing, coughing, exercise intolerance, and interference with sleep were more frequently associated with the oral metaproterenol regimen; completely asymptomatic days occurred 50% more frequently in association with theophylline therapy (P less than 0.01). Mean peak flows, performed twice daily during each of the four-week study periods, were 86 and 92% of predicted for metaproterenol and theophylline, respectively (P less than 0.05). Pulmonary function decreased significantly less with theophylline than with metaproterenol among those who completed six minutes of treadmill exercise during both regimens (P less than 0.05). Corticosteroids, used for acute symptoms that failed to respond to the addition of inhaled metaproterenol, were required in four patients during both regimens, in ten patients only during the metaproterenol regimen, and in one patient only during the theophylline regimen (P less than 0.02). Thus, theophylline therapy was associated with fewer adverse effects, fewer symptoms of asthma, better pulmonary function, better exercise tolerance, and less requirements for corticosteroids than was treatment with metaproterenol.

The role of pindolol in treating ventricular arrhythmia was studied in 43 patients with this disorder. Of these patients, 23 had coronary heart disease, 5 had valvular disease, and 15 had no demonstrable heart disease. patients underwent acute drug testing with 20 mg pindolol (phase 1) followed by maintenance therapy (phase 2) for 3 days (20 to 80 mg daily). Efficacy during both phases was evaluated by ambulatory monitoring and treadmill exercise testing. During acute drug testing, 50% of te patients responded. A concordant response between acute drug testing and phase 2 monitoring was seen in 81% (p less than 0.005) of patients and between acute drug testing and phase 2 exercise testing in 88% (p less than 0.005). Arrhythmia was suppressed during the phase 2 exercise test in 53% of patients; these included 80% of the patients without heart disease and 50% of those with coronary heart disease (not significant). During phase 2 monitoring, 60% of patients without heart disease responded vs. 25% with coronary heart disease (not significant). Side effects occurred in 12 patients (28%). These included congestive heart failure (3 patients); fatigue, lightheadedness, and insomnia (2 patients each); nausea, tremor, urinary retention, and bronchospasm (1 patient each); and aggravation of arrhythmia (7 patients). It is concluded that although pindolol alone is marginally effective for treating ventricular arrhythmia in patients with coronary heart disease, it appears to be more valuable in those without heart disease, especially when arrhythmia is provided by exercise. Acute drug testing proved highly predictive of the results with maintenance therapy and is a valuable rapid-screening procedure for identifying potential responders to pindolol.

The diazepam withdrawal syndrome was studied in 10 patients who had abused the drug for 3 to 14 years. In the previous 6 months their consumption of diazepam had ranged from 60 to 120 mg daily; none had used other drugs during this period. The withdrawal period lasted about 6 weeks. The intensity of the symptoms and signs was high initially, fell during the first 2 weeks, then rose again in the third week, before finally declining. Three groups of symptoms and signs were identified. Group A symptoms occurred throughout withdrawal and included tremor, anorexia, insomnia and myoclonus. Group B symptoms and signs were largely confined to the first 10 days and were those of a toxic psychosis. Group C symptoms reached a peak in the third and fourth weeks of withdrawal and were characterized by sense perceptions that were either heightened or lowered. The symptom groups, the presence of tremor and myoclonus, and the relief of symptoms by a test dose permit diazepam withdrawal to be distinguished from anxiety. The biphasic course of the symptoms is probably related to the pharmacokinetics of diazepam.

In a double-blind clinical trial with 20 patients suffering from endogenous depression statistically significant changes (improvement) were present in the scores of all assessment instruments. Although no statistically significant differences occurred between the groups, significant improvement on the HAM-D occurred earlier for amitriptyline and significant improvement occurred earlier on HAM-A for viloxazine. 2 patients were discontinued due to adverse reactions; one for nausea and vomiting while receiving viloxazine and one for paroxysmal atrial tachycardia while receiving amitriptyline. The same number of TES occurred for each group with seven unique to viloxazine (numbness, tingling, palpitation, ejaculation difficulty, nausea/vomiting, diarrhea, epigastric pain and gustatory disturbances) and seven unique to amitriptyline (insomnia, irritability, syncope, tremor, nasal congestion, orthostatic hypertension and paroxysmal atrial tachycardia). Other than for 1 patient who developed syncope and orthostatic hypotension and the patient who developed paroxysmal atrial tachycardia, there were no clinically significant changes in pulse rate, blood pressure and weight. There were no clinical laboratory findings with either drug that were judged to be pathological.
