Pharmacological action
Nicotinic acid is a specific antipellagric agent.
It has a pronounced short vasodilating effect, improves carbohydrate and nitrogen metabolism, has hypolipidemic activity, lowers total cholesterol, low density lipoproteins, triglycerides, increases high density lipoproteins, improves microcirculation.
In the body, nicotinic acid is converted into nicotinamide, which binds to the coenzymes of codehydrase I and codehydrase II (NAD and NADP), which carry hydrogen, and are involved in the metabolism of fats, proteins, amino acids, purines, tissue respiration, glycogenolysis, synthetic processes.
Replenishes the deficiency of vitamin PP (vitamin B3), being a specific anti-pellagric remedy.
Has a vasodilating effect at the level of small vessels (including the brain), improves microcirculation, has a weak anticoagulant effect (increases fibrinolytic activity of the blood).
Indications

– vascular spasms of the extremities
– as part of combination therapy for ischemic stroke
– obliterating diseases of the limb vessels (obliterating diabetes and mild illness including its complications (diabetic polyneuropathy, microangiopathy)
