Nicotinic acid bufus, 1% 1 ml 10 pcs

Nicotinic acid is a specific antipellagic agent. It has a pronounced short-term vasodilating effect, improves carbohydrate and nitrogen metabolism, has hypolipidemic activity, reduces total cholesterol, low-density lipoproteins, improves microcirculation.

In the body nicotinic acid is converted to nicotinamide, which binds to codohydrogen coenzymes I and II (NAD and NADPH), carrying hydrogen, is involved in the metabolism of fats, proteins, amino acids, purines, tissue respiration, glycogenolysis, synthetic processes. It compensates for the lack of vitamin PP (vitamin B3), is a specific antipellagic agent (vitamin PP avitaminosis).

Normalizes the concentration of blood lipoproteins.

It has a vasodilator effect at the level of small vessels (including brain).It also improves microcirculation and slightly anticoagulant effect (increases blood fibrinolytic activity).

Pharmacokinetics

During parenteral administration the drug is quickly distributed in body tissues. In body it is transformed into nicotinamide. It accumulates mainly in liver as well as in adipose tissue and kidneys. In the liver nicotinic acid is converted into amine, which is incorporated into nicotinamide adenine dinucleotide (NAD), which is a prosthetic group of enzymes that carry hydrogen and carry out redox processes.

Metabolized in the liver. Main metabolites are N-methyl-2-pyridone-3-carboxamide and N-methyl-2-pyridone-5-carboxamide have no pharmacological activity.

It can be synthesized in the intestine by bacterial flora from ingested tryptophan (from 60 mg of tryptophan 1 mg of nicotinic acid is formed) with the participation of pyridoxine (vitamin B6) and riboflavin (vitamin B12). Elimination half-life is 45 minutes.

It is excreted by kidneys as metabolites, at high doses – mainly unchanged. Renal clearance depends on the level of nicotinic acid in plasma and may decrease at high plasma concentrations.
