4 Clinical Particulars

4.9 Overdose

Ezetimibe/simvastatin. No specific treatment of overdosage with ezetimibe/simvastatin can be recommended. In the event of an overdose, symptomatic and supportive measures should be employed. Co-administration of ezetimibe (1000 mg/kg) and simvastatin (1000 mg/kg) was well-tolerated in acute, oral toxicity studies in mice and rats. No clinical signs of toxicity were observed in these animals. The estimated oral LD₅₀ for both species was ezetimibe ≥ 1000 mg/kg/simvastatin ≥ 1000 mg/kg.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).
Ezetimibe. In clinical studies, administration of ezetimibe, 50 mg/day to 15 healthy subjects for up to 14 days, or 40 mg/day to 18 patients with primary hypercholesterolemia for up to 56 days, and 40 mg/day to 13 patients with homozygous sitosterolemia for 26 weeks, was generally well tolerated.
A few cases of overdosage have been reported; most have not been associated with adverse experiences. Reported adverse experiences have not been serious.
Simvastatin. A few cases of overdosage have been reported; the maximum dose taken was 3.6 g. All patients recovered without sequelae.

5 Pharmacological Properties

5.3 Preclinical Safety Data

Genotoxicity. Ezetimibe/simvastatin. Ezetimibe alone or in combination with simvastatin did not cause gene mutation in bacteria or chromosomal damage in human peripheral lymphocytes or bone marrow cells in mice.
Carcinogenicity. Ezetimibe/simvastatin. Carcinogenicity studies with ezetimibe/simvastatin combinations have not been performed.
Ezetimibe. Two-year dietary studies with ezetimibe alone in mice and rats showed no evidence of carcinogenic potential. The highest ezetimibe dose (500 mg/kg/day) in mice corresponds to exposure levels approximately 4 and ≥ 150 times the adult human exposure for ezetimibe and total ezetimibe, respectively, based on AUC. Exposures in rats at the highest dose (1500 mg/kg/day in males and 500 mg/kg/day in females) correspond to approximately 2 and 14 times the adult human exposure for ezetimibe and total ezetimibe, respectively.
Simvastatin. Carcinogenicity studies have been conducted in mice at oral doses ranging from 1 to 400 mg/kg/day and in rats at doses of 1 to 100 mg/kg/day. Hepatocellular adenomas and carcinomas were observed in both sexes of both species at doses greater than 25 mg/kg/day. Plasma drug levels in rats at this no-effect dose level, expressed as the AUC for enzyme inhibitory activity, were 3 to 11 times greater than those in humans at the maximum recommended dose, whereas serum levels at the no-effect level in mice were similar to those in humans. Additional findings in mice were increased incidences of pulmonary adenomas at doses greater than 25 mg/kg/day, and of Harderian gland adenomas at 400 mg/kg/day. In rats, the incidence of thyroid follicular adenoma was increased in females at doses greater than 5 mg/kg/day and in males at doses greater than 25 mg/kg/day. These thyroid tumours were associated with focal cystic follicular hyperplasia, and may be a secondary effect reflective of a simvastatin-mediated enhancement of thyroid hormone clearance by the liver.
