Full Prescribing Info
Each tablet contains: Simvastatin 20 mg.
Pharmacology: Pharmacokinetics: Simvastatin is readily absorbed from the gastro-intestinal tract after oral administration. It is then hydrolysed to its active form, β-hydroxyacid, and metabolites (active and inactive). Less than 5% of Simvastatin goes to circulation as active metabolites, and about 95% of it and its active form are bound to plasma proteins. Primary means of excretion is thru the feces (as metabolites) and about 10-15% is eliminated in the urine as the inactive form.
Used to reduce low-density lipoprotein-cholesterol, apolipoprotein B and triglycerides, and to increase high-density cholesterol in the treatment of hyperlipidaemias. Also used as adjunct treatment in patient with homozygous familial hypercholesterolaemia, and is given prophylactically to hypercholesterolaemic patients with ischaemic heart disease.
Dosage/Direction for Use
For patients with ischaemic heart disease: Adults: Initial dose of 20 mg in the evening. Dosage may be adjusted at intervals of not less than 4 weeks up to a maximum of 80 mg once daily in the evening.
