Hypercholesterolemia

Active Ingredient: Lovastatin

Indication for Lovastatin

Population group: only adults (18 years old or older)

Severe cases of hypercholesterolaemia when dietary treatment does not have an adequate effect.

For this indication, competent medicine agencies globally authorize below treatments:

20-80 mg in 1-2 doses daily

Route of admnistration

Oral

Defined daily dose

20 - 80 mg

Dosage regimen

From 20 To 80 mg once every day

Detailed description

The patient should be placed on a standard cholesterol-lowering diet before being given lovastatin. This diet should be continued during treatment with lovastatin. Any cause for secondary hypercholesterolemia should be excluded before initiation of treatment.

The initial dose is generally 20 mg per day, given as a single dose with the evening meal. It has been shown that single daily doses given with the evening meal are more effective than the same dose given with breakfast, possibly because cholesterol synthesis takes place mainly at night. Patients with mild to moderate hypercholesterolemia may be treated with an initial dose of 10 mg lovastatin. Any dosage adjustments should be made at intervals of at least 4 weeks. A maximum of 80 mg should be given daily in a single dose or divided into 2 doses taken with breakfast and the evening meal. Two daily doses would appear to be more effective than one daily dose.

The dosage of lovastatin should be reduced if LDL-cholesterol levels drop below 75 mg/dL (1.94 mmol/L), or if total serum cholesterol concentrations fall below 140 mg/dL (3.6 mmol/L).

Concomitant treatment

Lovastatin is effective alone or in combination with bile-acid sequestrants.

In patients being given cyclosporine, danazol, gemfibrozil, other fibrates or lipid-lowering doses (≥1 g/day) of niacin at the same time as lovastatin, the maximum recommended dose is 20 mg/day. In patients taking amiodarone or verapamil concomitantly with lovastatin, the dose of lovastatin should not exceed 40 mg/day.

Active ingredient

Lovastatin

Lovastatin, which is an inactive lactone, is hydrolysed after oral administration to the corresponding β-hydroxyacid. This is the major metabolite and an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase, an enzyme that catalyses an early and rate-limiting step in the biosynthesis of cholesterol.
