General pharmacological properties of isepamicin sulfate (HAPA-B), a new aminoglycoside antibiotic, were studied in animals and the results obtained were summarized below. Intramuscular injections of HAPA-B at doses of 500 mg/kg inhibited the writing response induced by acetic acid, and at doses of 1,000 mg/kg, caused muscle relaxation, respiratory depression, suppression of spontaneous motor activity and prolongation of thiopental anesthesia. Anticonvulsive action and the effect on the rectal temperature were not observed.

Intravenous injections of HAPA-B to anesthetized dogs resulted increases in the femoral arterial blood flow at doses of 12.5 mg/kg, decrease in the blood pressure and increase in the respiratory rate at doses of 25 mg/kg, and increase in the carotid arterial blood flow at doses of 50 mg/kg.
