A long-term prevention study with oxprenolol in coronary heart disease.

We carried out a randomized double-blind controlled secondary-prevention trial of oxprenolol over seven years. Forty milligrams of oxprenolol or placebo was given twice daily to 1103 men 35 to 65 years old who had an acute myocardial infarction between 1 and 90 months previously. Overall, there was no difference in mortality or cardiac events between the placebo and oxprenolol groups. The major influence on prognosis was the time at which treatment was started after infarction. In 417 patients in whom treatment was started within four months of infarction oxprenolol increased the six-year cumulative survival rate from 77 to 95 per cent (P less than 0.001). In 274 patients with treatment starting between 5 and 12 months of infarction the survival rate was similar in the two groups, but in 412 patients entered between 1 and 7 1/2 years after their first infarction oxprenolol reduced the six-year survival rate from 92 to 79 per cent (P = 0.002). The increased mortality in this latter group mainly occurred late after withdrawal from active treatment. The value of low-dose oxprenolol in secondary prevention appears to be confined to patients treated relatively soon after myocardial infarction.

Drug controlled of Cushing's syndrome. Combined aminoglutethimide and metyrapone therapy.

Eighteen patients with Cushing's syndrome (16 pituitary-dependent Cushing's disease, 1 ectopic ACTH syndrome, 1 primary adrenal adenoma) were given a combination of aminoglutethimide and metyrapone, with the object of controlling cortisol overproduction using less toxic doses than would be required with each drug alone. A preliminary trial of this combination using doses of aminoglutethimide of 1 g or more a day was assessed over 2 weeks. Control of cortisol overproduction and clinical improvement was achieved but side effects led to withdrawal of the drugs in 6 out of the 12 patients. A lower dose trial of this combination over 2 weeks, using 750 mg/day of aminoglutethimide also controlled cortisol overproduction and side effects led to drug withdrawal in only 2 out of 6 patients. Four of these patients were successfully controlled with even lower doses (500-750 mg/day of aminoglutethimide) for longer periods (26 days-1 year). This low regimen which consists of aminoglutethimide 500-750 mg daily, metyrapone 2 g daily, dexamethasone 0.5 mg b.d. and fludrocortisone 0.1 mg daily, is useful for preparing patients for operative treatments and may be used as a long-term treatment of milder cases.

Anabolic steroids in athelics: crossover double-blind trial on weightlifters.

Thirteen experienced male weightlifters taking high-protein diets and regular exercise took part in a double-blind crossover trial of methandienone 10 or 25 mg/day to seeif the drug improved athletic performance. Their improvemments were significantly greater on methandienone than on placebo; their body weights rose (though this seemed to be associated with water retention); and systolic blood pressure rose significantly. Methandienone caused many side effects, and three men had to withdraw because of them. All side effects disappeared after the drug was stopped. Anabolic steroids are effective only when given combination with exercise and high-protein diet. We deprecate their use in athletics but can suggest no way of stopping it.

Effect of rifampicin and isoniazid on liver function.

The effects of rifampicin and isoniazid on liver function have been studied in 63 patients with pulmonary tuberculosis; 29% showed abnormalities of serum aspartate aminotransferase (SGOT) and a similar percentage abnormalities of serum bilirubin. These usually occurred during the first 12 weeks of therapy. The average duration of the abnormalities was 14(1/2) days, irrespective of whether treatment was interrupted or not.The relationship between raised SGOT and acetylator phenotype in a small number of patients suggests that those with raised SGOT are usually slow acetylator phenotypes. It seems that hepatic reactions in patients with previously normal liver function are usually mild and non-specific. However, patients who continue with rifampicin should be kept under close biochemical observation.
