• Drug Groups: approved; nutraceutical; investigational
• Description: A water-soluble vitamin of the B complex occurring in various animal and plant tissues. It is required by the body for the formation of coenzymes NAD and NADP. It has pellagra-curative, vasodilating, and antilipemic properties. [PubChem]
• Indication: For the treatment of type IV and V hyperlipidemia. It is indicated as ajunctive therapy.
• Pharmacology: Niacin and niacinamide are indicated for prevention and treatment of vitamin B3 deficiency states. Vitamin B3 (Niacin) also acts to reduce LDL cholesterol, triglycerides, and HDL cholesterol. The magnitude of individual lipid and lipoprotein responses may be influenced by the severity and type of underlying lipid abnormality. The increase in total HDL is associated with a shift in the distribution of HDL subfractions (as defined by ultra-centrifugation) with an increase in the HDL2:HDL3 ratio and an increase in apolipoprotein A-I content. Vitamin B3 (Niacin) treatment also decreases the serum levels of apolipoprotein B-100 (apo B), the major protein component of the VLDL (very low-density lipoprotein) and LDL fractions, and of lipoprotein-a, a variant form of LDL independently associated with coronary risk.
• Toxicity: Nicotinic acid can cause vasodilation of cutaneous blood vessels resulting in increased blood flow, principally in the face, neck and chest. This produces the niacin- or nicotinic acid-flush. The niacin-flush is thought to be mediated via the prostaglandin prostacyclin. Histamine may also play a role in the niacin-flush. Flushing is the adverse reaction first observed after intake of a large dose of nicotinic acid, and the most bothersome one. LD₅₀ 7000 mg/kg (Rat)
• Affected Organisms: Humans and other mammals
• Biotransformation: Hepatic
• Absorption: Both nicotinic acid and nicotinamide are efficiently absorbed from the stomach and small intestine.
• Half Life: 20-45 minutes.

Research Area: Metabolic Disease
Biological Activity:
Niacin(Nicotinic acid) is a water-soluble vitamin belonging to the vitamin B family, which occurs in many animal and plant tissues, with antihyperlipidemic activity. Niacin is converted to its active form niacinamide, which is a component of the coenzymes nicotinamide adenine dinucleotide (NAD) and its phosphate form, NADP. These coenzymes play an important role in tissue respiration and in glycogen, lipid, amino acid, protein, and purine metabolism. [1, 2]

Nicotinic acid. It is a precursor of the coenzymes NAD and NADP. Widely distributed in nature; appreciable amounts are found in liver , fish, yeast and cereal grains. Dietary deficiency is associated with pellagra. The term “niacin” has also been applied
