Indications for: Lovastatin

To reduce risk of MI, unstable angina, and coronary revascularization procedures in patients without symptomatic cardiovascular disease (CVD), average to moderately elevated total-C and LDL-C, and below average HDL-C. Primary hypercholesterolemia (Types IIa and IIb) to reduce elevated total-C and LDL-C when response to nondrug therapy is inadequate. To slow progression of coronary atherosclerosis in patients with coronary heart disease to lower total-C and LDL-C. Adjunct to nondrug therapy to reduce total-C, LDL-C and apo B in patients 10–17yrs of age (≥1yr post-menarche) with heterozygous familial hypercholesterolemia if LDL-C remains >189mg/dL, or if LDL-C remains >160mg/dL with either family history of premature cardiovascular disease (CVD) or if patient has at least 2 other CVD risk factors.

Adult Dosage:

Give with evening meal. ≥17yrs: initially 10–20mg once daily, may increase at 4 week intervals; max 80mg/day in single or divided doses. Concomitant danazol, diltiazem, dronedarone, verapamil: initially 10mg/day; max 20mg/day. Concomitant amiodarone: max 40mg/day. Severe renal insufficiency (CrCl<30mL/min): 20mg/day; caution with dose increases.

Children Dosage:

<10yrs: not recommended. 10–17yrs: initially 10–20mg once daily, may increase at 4 week intervals. Usual range: 10–40mg/day; max 40mg/day.

Discontinue if myopathy, elevated CPK levels occur; suspend if a predisposition to development of renal failure secondary to rhabdomyolysis develops. Monitor liver function before starting therapy and repeat as clinically indicated. History of liver disease. Alcoholism. Homozygous familial hypercholesterolemia.

Lovastatin Classification:
