Definitions
- the present invention relates to oral pharmaceutical compositions of fenofibrate having high bioavailability with improved dissolution and methods for preparing the pharmaceutical compositions.
- Fenofibrate 2-[4-(4-chlorobenzoyl) phenoxy]-2-methyl-propanoic acid, 1- methylethyl ester, belongs to the family of fibrates or fibric acid derivatives. It is commercially available as oral capsules containing micronized fenofibrate in the strengths of 67 mg, 134 mg and 200 mg. Fenofibrate is indicated as an adjunctive therapy to diet for the treatment for adult patients with very high elevations of serum triglyceride levels who are at risk of pancreatitis and who do not respond adequately to dietary control. It is particularly useful for the treatment of adult endogenous hyperlipidemia, hypercholesterolemia and hypertriglyceridemia.
- Fenofibrate is practically insoluble in water and exhibits a low rate of dissolution in aqueous media that results in inadequate bioavailability after oral ingestion. This low rate of dissolution of fenofibrate in aqueous media also is found in gastrointestinal fluids.
