Experimental and clinical trials to determine the potential of prenylamine in the prevention of adriamycin-related cardiotoxicity are reviewed. In mice given 4 mg/kg body weight adriamycin, the incidence of myocardial damage after 19 days' treatment was lower than in those given adriamycin and placebo. Rabbits were given adriamycin (total dose 10.8 mg/kg body weight), adriamycin plus prenylamine (1.5 mg/kg body weight), and adriamycin plus vitamins A (250 IU) and E (40 mg) for 9-11 weeks. Adriamycin-induced electrocardiogram changes were observed to a lesser extent in animals also receiving prenylamine. Heart homogenates from adriamycin-treated animals showed enhanced hydroperoxide-initiated chemiluminescence which was not affected by the simultaneous administration of prenylamine. The extent of adriamycin-induced myocytolysis and the degree of alterations observed on electron microscopy were markedly reduced by prenylamine. In a double-blind clinical trial with 26 oncological patients, no cardiomyopathy, arrhythmia or adverse reactions were observed in the group given adriamycin plus prenylamine. In those given adriamycin plus placebo, two patients developed congestive cardiopathy and another showed severe supraventricular arrhythmias together with hypotension and dyspnoea. The mechanisms of adriamycin-related cardiotoxicity, the effects of prenylamine and the benefit from combined treatment are discussed.
