Fenofibric acid

Absorption

Some studies have demonstrated that the bioavailability of fenofibric acid (a sample administration of 130 mg oral suspension to healthy volunteers about 4 hours after a light breakfast) is approximately 81% in the stomach, 88% in the proximal small bowel, 84% in the distal small bowel, and 78% in the colon . Nevertheless, following the oral administration of fenofibric acid in healthy volunteers, median peak plasma levels for the drug occurred about 2.5 hours after administration . Moreover, exposure after administration of three 35 mg fenofibric acid tablets is largely comparable to that of one 105 mg tablet .

DPP4 inhibitor, antidiabetic

Background

Fenofibric acid is a lipid-lowering agent that is used in severe hypertriglyceridemia, primary hyperlipidemia, and mixed dyslipidemia. It works to decrease elevated low-density lipoprotein cholesterol, total cholesterol, triglycerides, apolipoprotein B, while increasing high-density lipoprotein cholesterol. Due to its high hydrophilicity and poor absorption profile, prodrug ,fenofibrate, and other conjugated compounds of fenofibric acid, such as choline fenofibrate, have been developed for improved solubility, gastrointestinal absorption, and bioavailability, and more convenient administration.

Indications

For use as an adjunctive therapy to diet to: (a) reduce triglyceride levels in adult patients with severe hypertriglyceridemia, and (b) reduce elevated total cholesterol, low-density-lipoprotein (LDL-C), triglycerides, and apolipoprotein B, and to increase high-density-lipoprotein (HDL-C) in adult patients with primary hypercholesterolemia or mixed dyslipidemia (Fredrickson Types IIa and IIb).

What are the applications of Application

Fenofibric Acid is the active metabolite of fenofibrate

Definition

ChEBI: A monocarboxylic acid that is 2-methylpropanoic acid substituted by a 4-(4-chlorobenzoyl)phenoxy group at position 2. It is a metabolite of the drug fenofibrate.

Pharmacokinetics

Various clinical studies have shown that elevated levels of total cholesterol, low-desnsity-lipoprotein (LDL-C), and apolipoprotein B (apo B) - an LDL membrane complex - are associated with human atherosclerosis . Concurrently, decreased levels of high-density-lioprotein (HDL-C) and its transport complex, apolipoproteins apo AI and apo AII, are associated with the development of atherosclerosis . Furthermore, epidemiological investigations demonstrate that cardiovascular morbidity and mortality vary directly with the levels of total cholesterol, LDL-C, and triglycerides, and inversely with the level of HDL-C .
Fenofibric acid, the active metabolite of fenofibrate, subsequently produces reductions in total cholesterol, LDL-C, apo B, total triglycerides, and triglyceride rich lipoprotein (VLDL) in treated patients . Moreover, such treatment with fenofibrate also results in increases in HDL-C and apo AI and apo AII .

Metabolism

In vitro and in vivo metabolism studies reveal that fenofibric acid does not experience significant oxidative metabolism via the cytochrome P450 isoenzymes . The CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4 enzymes are not known to play a role in the metabolism of fenofibric acid .
Rather, fenofibric acid is predominantly conjugated with glucuronic acid and then excreted in urine . A small amount of fenofibric acid is reduced at the carbonyl moiety to benzhydrol metabolite which is, in turn, conjugated with glucuronic acid and excreted in urine .
