Toxicological studies on cefuroxime sodium.
The intravenous LD50 of cefuroxime sodium for mice was 10.4 g/kg. The maximum dosage administered in other acute toxicity tests was well tolerated by mice (10 g/kg, subcutaneous), by rats (4 g/kg, intravenous, 5 g/kg, subcutaneous) and by cats, dogs and monkeys (2 g/kg, intramuscularly). Cefuroxime sodium was administered subcutaneously (s.c.) or intramuscularly (i.m.) for 3 months to rats (100, 300 or 900 mg/kg/day) followed by a recovery period, and also for 6 months to rats and dogs (50, 150 or 450 mg/kg/day) and for 1 month to monkeys (150 or 450 mg/kg/day). In all these tests there were no serious toxic effects. Minor haematological changes were attributable in part if not entirely to haemorrhage and tissue reaction at the site of injection of large doses. In rats large doses caused some increase in urine volume and electrolyte excretion, and slightly aggravated an age related nephropathy. Administration to rats intravenously (i.v.) for1 month of up to 400 mg/kg/day had no toxic effects. In reproduction studies on mice and rabbits there were no adverse effects on fertility, organogenesis or the rearing of young.
