PRAVASTATIN SODIUM- pravastatin sodium tablet
Glenmark Generics Inc., USA
1 INDICATIONS AND USAGE
Therapy with lipid-altering agents should be only one component of multiple risk factor intervention in individuals at significantly increased risk for atherosclerotic vascular disease due to hypercholesterolemia. Drug therapy is indicated as an adjunct to diet when the response to a diet restricted in saturated fat and cholesterol and other nonpharmacologic measures alone has been inadequate.
1.1 Prevention of Cardiovascular Disease
In hypercholesterolemic patients without clinically evident coronary heart disease (CHD), pravastatin sodium tablets USP are indicated to:
reduce the risk of myocardial infarction (MI).
reduce the risk of undergoing myocardial revascularization procedures.
reduce the risk of cardiovascular mortality with no increase in death from non-cardiovascular causes.
Pravastatin sodium tablets USP are indicated:
as an adjunct to diet to reduce elevated total cholesterol (Total-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (ApoB), and triglyceride (TG) levels and to increase high-density lipoprotein cholesterol (HDL-C) in patients with primary hypercholesterolemia and mixed dyslipidemia (Fredrickson Types IIa and IIb).1
as an adjunct to diet for the treatment of patients with elevated serum TG levels (Fredrickson Type IV).
for the treatment of patients with primary dysbetalipoproteinemia (Fredrickson Type III) who do not respond adequately to diet.
as an adjunct to diet and lifestyle modification for treatment of heterozygous familial hypercholesterolemia (HeFH) in children and adolescent patients ages 8 years and older if after an adequate trial of diet the following findings are present:
LDL-C remains ?190 mg/dL or
LDL-C remains ?160 mg/dL and:
there is a positive family history of premature cardiovascular disease (CVD) or
two or more other CVD risk factors are present in the patient.
1.3 Limitations of Use
Pravastatin sodium tablets USP have not been studied in conditions where the major lipoprotein abnormality is elevation of chylomicrons (Fredrickson Types I and V).
2 DOSAGE AND ADMINISTRATION
2.1 General Dosing Information
The patient should be placed on a standard cholesterol-lowering diet before receiving pravastatin sodium tablets and should continue on this diet during treatment with pravastatin sodium tablets [see NCEP Treatment Guidelines for details on dietary therapy].
12.1 Mechanism of Action
Pravastatin is a reversible inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase, the enzyme that catalyzes the conversion of HMG-CoA to mevalonate, an early and rate limiting step in the biosynthetic pathway for cholesterol. In addition, pravastatin reduces VLDL and TG and increases HDL-C.
Pravastatin sodium tablets USP are one of a class of lipid-lowering compounds, the statins, which reduce cholesterol biosynthesis. These agents are competitive inhibitors of HMG-CoA reductase, the enzyme catalyzing the early rate-limiting step in cholesterol biosynthesis, conversion of HMG-CoA to mevalonate.
Pravastatin sodium USP is designated chemically as 1-Naphthalene-heptanoic acid, 1,2,6,7,8,8a-hexahydro-?,?,6-trihydroxy-2-methyl-8-(2-methyl-1-oxobutoxy)-, monosodium salt, [1S[1?(?S*,?S*),2?,6?,8?(R*),8a?]]-.
