The efficacy and tolerability of the selective 5-HT reuptake inhibitor fluvoxamine were compared with the tricyclic dothiepin in 52 elderly (age greater than 64 years) hospital patients in a multi-centre double-blind randomised trial. Patients met DSM-III criteria for 'major depressive episode' and scored greater than 29 on the Montgomery Asberg Depression Rating Scale (MADRS) after a one-week placebo baseline. Active treatment was for six weeks. The dosage of both drugs was 50 mg nocte for three days, 100 mg nocte for the remainder of the first week, thereafter increasing to a maximum of 200 mg/day according to response/tolerance. MADRS scores improved by 63.5% with fluvoxamine and 60.0% with dothiepin; there were no significant differences between treatments at any assessment. Nausea, dizziness, headache, somnolence and constipation in both groups, plus dry mouth and asthenia in the dothiepin group were more frequent than single reports. Two patients in each group discontinued treatment owing to unwanted effects. There were no clinically significant changes in haematological, biochemical or cardiovascular parameters.

The efficacy and safety of bepridil hydrochloride (200 to 400 mg/day) were evaluated in patients with chronic stable angina refractory to maximal tolerated doses of diltiazem (median 360 mg/day) in a randomized, multicenter, double-blind, parallel study. Baseline diltiazem data were obtained during a 2-week period, after which 86 patients were randomized to bepridil (n = 46) or diltiazem (n = 40). Angina frequency, nitroglycerin consumption and ischemic manifestations induced by exercise treadmill testing were evaluated over 8 weeks. Bepridil significantly (p less than 0.05) increased time to angina onset, time to 1 and 2 mm of ST-segment depression, total exercise time and total work over baseline values. Changes in time to angina onset and time to 1 mm of ST-segment depression were significantly (p less than 0.05) greater for bepridil than for diltiazem. Angina frequency and nitroglycerin consumption did not differ significantly between groups. Compared with baseline, bepridil significantly (p less than 0.001) decreased heart rate (mean 4 beats/min) and prolonged QTc (mean 35 ms). The most frequent adverse effects in both groups were nausea, asthenia, dizziness, headache and diarrhea. Four patients taking bepridil and 1 taking diltiazem withdrew from the study because of adverse reactions. No sudden deaths, myocardial infarctions or instances of sustained ventricular tachycardia or torsades de pointes occurred in either group. The data indicate that bepridil provided safe and effective antianginal and antiischemic therapy in patients with chronic stable angina who exhibited less than optimal response to maximal tolerated doses of diltiazem.

The 159 patients with Parkinson's disease with onset after the age of 50 (mean: 62.3 years) were studied with reference to diagnosis and treatment. The results were as follows: 1. Other than the characteristic features, the symptoms at onset were depression (6% of the patients), lumbago (4%), hemiplegia-like (4%) and dizziness (3%), causing misdiagnoses in some of the patients. Among 159 patients studied, the severity most frequent was Yahr stage 3 (63%) at first examination, indicating the necessity of earlier diagnosis. 2. Magnetic resonance imaging (MRI) of the substantia nigra and striatum was investigated using a 1.5 Tesla field and T2-weighted images, which gave no specific results concerning diagnosis and severity. However, it was useful in differential diagnosis between this disease and parkinsonism caused by multiple system atrophy and cerebrovascular diseases. 3. With 123I-IMP SPECT, decrease in blood flow in the frontal and temporal lobes correlated with the severity (Yahr stage) of the disease. Regarding cognitive functions the scores of Hasegawa's Dementia Scale and Mini-Mental State showed a highly significant correlation with the amount of blood flow in frontal and parietal lobes, suggesting that dementia might be caused by dysfunction of these lobes. 4. In 98 patients treated with levodopa mixed with dopa-economizers for more than a year, the maximum improvement was small in severely disabled patients of Yahr stage 5 and 4 because none improved to stage 3A or below (3A is an arbitrary criterion meaning mild involvement in stage 3 with 3P meaning more severe cases).(ABSTRACT TRUNCATED AT 250 WORDS)

Major depression disease is uncommon in children; it occurs mostly in children with a depressed parent or in children under major psychosocial stress such as physical or sexual abuse. Most depression in children is masked, i.e., the child presents with signs or symptoms such as headaches, abdominal pain, muscle weakness, vomiting, dizziness, hyperactivity, or school avoidance. Careful evaluation of the history is required to assist in the diagnosis. Some basic laboratory tests should be done to rule out organic disease. Psychiatric referral should be carried out after an appropriate evaluation.

Following a 1-week, single-blind placebo washout, 150 patients were randomized to double-blind treatment with daily doses of either mianserin, 30 mg to 150 mg; amitriptyline, 60 mg to 300 mg; or placebo, 1 to 5 capsules taken at bedtime (qhs). Mianserin and amitriptyline were found to be comparable in efficacy, and both significantly more effective than placebo in the treatment of major depressive illness. Rating instruments, all of which showed significant improvement in the active drug groups over the placebo, included the 17- and 21-item Hamilton Rating Scale for Depression (HAM-D), Montgomery and Asberg Depression Rating Scale (MADRS), Self-rating Depression Scale (SDS) index, and the Clinical Global Impressions (CGI) Severity of Illness and Improvement rating scales. Furthermore, for most efficacy parameters in the efficacy-evaluable group, the earliest statistically significant difference vs. placebo could be observed at Visit 1 for the mianserin patients and at Visit 3 for the amitriptyline patients. The safety profile for mianserin was comparable with placebo with respect to laboratory values, electrocardiogram changes, vital signs, ophthalmologic evaluations, and most adverse clinical experiences. Complaints of somnolence and weight gain were comparable in the amitriptyline and mianserin groups. Mianserin was superior to amitriptyline in terms of vital signs; anticholinergic effects; and complaints of dizziness, dyspepsia, and tremor.

Clomipramine is a newly marketed tricyclic antidepressant drug prescribed for obsessive-compulsive disorder (OCD). It selectively blocks neuronal uptake of serotonin. Clomipramine has been prescribed in Europe and Canada for 20 years in management of depression. Studies have now shown clomipramine to be effective in treating OCD. Dry mouth, visual disturbances, constipation, sexual dysfunction, somnolence, tremors, and dizziness are among the commonly reported side effects. Like other tricyclics, clomipramine exhibits a potential for cardiotoxicity, especially by impairing conduction and/or orthostasis. It also has the effect of lowering seizure threshold. Overdose risk is considerable. Careful medical supervision and adherence to prescribing guidelines are presumed to reduce medication risk factors. The outstanding benefit of this drug is its proved efficacy in the management of obsessive-compulsive disorder, as the first pharmacotherapy approved for this previously rather treatment-resistant condition.

A phase I clinical study of intravenous Tegafur was conducted in nineteen previously treated patients with primary lung cancer. The dose of Tegafur was elevated from 1.0 to 3.0 g/m2/day for five consecutive days to determine the maximum tolerated dose. The dose-limiting factors were gastrointestinal and neurological toxicity and fatigability observed with the dose level of 2.5 g/m2/day for 5 days. Hematologic, hepatic and renal toxicities were not observed. Gastrointestinal toxicity including nausea, vomiting, anorexia and diarrhea of over grade 2 were seen to result from the dose of 2.5 g/m2/day. Neurological toxicity consisted of headache, dizziness, anxiety and depression. At the dose level of 2.0 g/m2/day, one patient, who had epileptic seizures in the past, experienced a psychomotor seizure. Depression (Grade 2 CNS toxicity) was observed at the dose level of 3.0 g/m2/day. Dose limiting factors were neurological toxicities. The pharmacokinetics of tegafur and 5-FU (the active form of Tegafur) has been studied in all patients. Serum level of tegafur was measured by HPLC method, and serum level of 5-FU was analyzed by GC-MS method. At the dose level greater than 2.0 g/m2/day for 5 days, the mean serum 5-FU values appear over the therapeutic range (0.1 micrograms/ml). In conclusion, 2.5 g/m2/day for 5 days was considered to be MTD, and 2.0 g/m2/day for 5 days intravenous administration was recommended for the phase II trial of single agent chemotherapy.

Fifty-seven hospital out-patients with depressive symptoms were studied in a double-blind manner for up to 4 weeks, 30 whilst being treated with intramuscular flupenthixol decanoate (5 to 10 mg/fortnight) and 27 with oral amitriptyline (75 to 150 mg/day). The results of assessment using the Hamilton Rating Scale for Depression, the Leeds Self-Rating Scale for Depression and the Clinical Global Impressions severity scale showed that both therapies were effective in resolving depression in the patients studied. The two treatments were well tolerated and side-effect profiles were similar, dry mouth, faintness/dizziness and drowsiness being the most frequently reported adverse events. Extrapyramidal signs were seen in similar numbers of patients in each treatment group. One patient from each of the two groups was withdrawn from therapy before the end of the study because of adverse events.

Data from two large, fixed-dose trials support the efficacy of a fixed 20 mg/day dose of fluoxetine in the treatment of depression. Data pooled from these two studies suggest a dose relationship for adverse events during fluoxetine therapy. At a fixed 20 mg/day dose, only nausea and insomnia were reported by a significantly greater percentage of patients (p less than .05) than those treated with placebo. However, at 60 mg/day, nausea, anxiety, dizziness, and insomnia were reported by a significantly greater percentage of patients (p less than .05) than those treated with placebo. The potential relationship of response rate [Hamilton Rating Scale for Depression (HAM-D) total decrease greater than or equal to 50%] to plasma concentrations of fluoxetine, norfluoxetine, and fluoxetine plus norfluoxetine was evaluated in one study which excluded early responders (less than or equal to 3 weeks of therapy). No significant relationship was found. Furthermore, adverse events were not related to plasma concentrations.

Nonsalicylate, nonsteroidal anti-inflammatory drugs (NSAIDs) can be divided into 4 chemical classes: acetic acids, fenamic acids, oxicams and propionic acids. Most NSAID overdoses result in a benign outcome. Of 50,614 exposures reported to poison centres in the United States in a 2-year period, 131 (0.26%) had a major outcome, with 10 deaths. Despite the generally mild effects reported in large patient series, isolated case reports have documented serious toxicity, such as seizures, hypotension, apnoea, coma and renal failure. The majority of these consequences occur after ingestion of substantial quantities by adults attempting suicide. Rarely, with ibuprofen and piroxicam, children who ingest small amounts in accidental exposure develop serious toxicity. Typical signs and symptoms of NSAID overdose include nausea, vomiting, headache, drowsiness, blurred vision and dizziness. Seizures are rarely documented across all NSAID classes, with the exception of mefenamic acid (where seizures occur in over one-third of cases), or following massive ingestion of other agents. Drugs in the propionic acid group have produced metabolic acidosis, respiratory depression and coma in severe cases. Ibuprofen is the agent with the most published data on overdose, probably because it is available without a prescription in many countries. Symptoms are unlikely after ingestion of 100 mg/kg or less, and are usually not life-threatening unless more than 400 mg/kg is ingested. There is some relationship between plasma concentrations and the potential for development of symptoms, but plasma concentrations have no impact on treatment decisions. Treatment of NSAID overdose is entirely supportive. Recent trends in emergency department procedures regarding gastric decontamination are evolving towards the recommended administration of activated charcoal without gastric emptying in patients presenting more than 1 hour after ingestion, although gastric lavage, followed by administration of activated charcoal, may be advisable in patients who present earlier. Home administration of syrup of ipecac is still recommended if treatment is given shortly after ingestion, with a few exceptions: for example, ipecac is contraindicated after ingestion of mefenamic acid or ibuprofen in amounts greater than 400 mg/kg. Urine alkalinisation and diuresis have been recommended to enhance the elimination of NSAIDs, based on a pKa in the range of 3 to 5. However, because the drugs are universally highly protein bound, with little unchanged renal excretion, this technique is not likely to be beneficial. Haemodialysis is also unlikely to enhance elimination, but may be required if oliguric renal failure develops. Multiple dose activated charcoal may be useful in enhancing elimination of NSAIDs with long half-lives, such as piroxicam and sulindac.
