PRESCRIPTION DRUG
1) Prevalite® (cholestyramine for oral suspension, USP) powder is indicated as adjunctive therapy to diet for the reduction of elevated serum cholesterol in patients with primary hypercholesterolemia (elevated low density lipoprotein [LDL] cholesterol) who do not respond adequately to diet. Prevalite® (cholestyramine for oral suspension, USP) powder may be useful to lower LDL cholesterol in patients who also have hypertriglyceridemia, but it is not indicated where hypertriglyceridemia is the abnormality of most concern. Therapy with lipid-altering agents should be a component of multiple risk factor intervention in those individuals at significantly increased risk for atherosclerotic vascular disease due to hypercholesterolemia. Treatment should begin and continue with dietary therapy specific for the type of hyperlipoproteinemia determined prior to initiation of drug therapy. Excess body weight may be an important factor and caloric restriction for weight normalization should be addressed prior to drug
Prevalite® (cholestyramine for oral suspension, USP) powder is available in cartons of forty-two and sixty single-dose packets and in cans containing 231 grams. 5.5 grams of Prevalite® (cholestyramine for oral suspension, USP) powder contain 4 grams of anhydrous cholestyramine resin. Store at 20° to 25°C (68° to 77°F); excursions permitted to 15° to 30°C (59° to 86°F) [See USP Controlled Room Temperature].
Abbreviated New Drug Application
PREVALITE- CHOLESTYRAMINE POWDER, FOR SUSPENSION UPSHER-SMITH LABORATORIES, LLC ---------- PREVALITE (CHOLESTYRAMINE FOR ORAL SUSPENSION, USP) RX ONLY DESCRIPTION Prevalite (cholestyramine for oral suspension, USP) powder, the chloride salt of a basic anion exchange resin, a cholesterol-lowering agent, is intended for oral administration. Cholestyramine resin is quite hydrophilic, but insoluble in water. The cholestyramine resin in Prevalite (cholestyramine for oral suspension, USP) is not absorbed from the digestive tract. 5.5 grams of Prevalite (cholestyramine for oral suspension, USP) contain 4 grams of anhydrous cholestyramine resin. It is represented by the following structural formula: Prevalite (cholestyramine for oral suspension, USP) powder contains the following inactive ingredients: aspartame, FD&C Yellow No. 6, malic acid, polysorbate 80, propylene glycol alginate, and orange flavor. CLINICAL PHARMACOLOGY Cholesterol is probably the sole precursor of bile acids. During normal digestion, bile acids are secreted into the intestines. A major portion of the bile acids is absorbed from the intestinal tract and returned to the liver via the enterohepatic circulation. Only very small amounts of bile acids are found in normal serum. Cholestyramine resin adsorbs and combines with the bile acids in the intestine to form an insoluble complex which is excreted in the feces. This results in a partial removal of bile acids from the enterohepatic circulation by preventing their absorption. The increased fecal loss of bile acids due to cholestyramine resin administration leads to an increased oxidation of cholesterol to bile acids, a decrease in beta lipoprotein or low density lipoprotein plasma levels and a decrease in serum cholesterol levels. Although in man, cholestyramine resin produces an increase in hepatic synthesis of cholesterol, plasma cholesterol levels fall. In patients with partial biliary obstruction, the reduction of serum bile acid levels by cholestyramine resin reduces excess bile acids deposited in Preberite celoten dokument
