Biochem/physiol Actions

Acipimox, also known as olbemox, is a nicotinic acid analog. It functions as an anti-lipolytic drug and vasodilator. Acipimox may be used in various metabolic studies involving insulin and ghrelin. It lowers total cholesterol and total triglycerides, which helps in the treatment of hyperlipidemia.
Niacin-derived, vasodilator studied for its lipid-lowering effect.

Circulating free fatty acids (FFAs) may worsen heart failure (HF) due to myocardial lipotoxicity and impaired energy generation. We studied cardiac and whole body effects of 28 days of suppression of circulating FFAs with acipimox in patients with chronic HF.

Metabolic syndrome is a proatherosclerotic condition clustering cardiovascular risk factors, including glucose and lipid profile alterations. The pathophysiological mechanisms favoring atherosclerotic inflammation in the metabolic syndrome remain elusive. Here, we investigated the potential role of the antilipolytic drug acipimox on
Impaired growth hormone secretion in obese subjects is partially reversed by acipimox-mediated plasma free fatty acid depression

Changes in glucose metabolism occurring during counterregulation are, in part, mediated by increased plasma free fatty acids (FFAs), as a result of hypoglycemia-activated lipolysis. However, it is not known whether FFA plays a role in the development of posthypoglycemic insulin

The study was designed to compare the pharmacokinetic parameters and relative bioavailability of a newly generic acipimox 250-mg tablets (test formulation) with a branded 250-mg tablets (reference formulation). A single-dose, randomized-sequence, 2-way crossover study was conducted in 20 healthy Chinese
