Mutagenicity obtained experimentally by oral administration of dextroamphetamine sulphate to the rat

Research work on the possible mutagenic effects of the amphetamine, sympathomimetic amine, was carried out on the rat. The method used was the dominant lethal assay, in its sub-acute form. Dextroamphetamine sulphate was administered orally. At the dosage and frequency of the test, dextroamphetamine sulphate was found to be a significantly mutogenic agent. The over-all mutagenic index was 13.92% (P less than 0.01) for the test group and 8.90% for the control group.
