What is Inositol nicotinate ?
Absorption
Gastrointestinal absorption of inositol hexanicotinate varies widely, with an average of 70% of an orally ingested dose absorbed from stomach and upper small intestines into the bloodstream as intact form. The maximum serum levels of nicotinic acid is reached approximately 6-10 hours after oral ingestion. At low concentrations, the absorption of nicotinic acid and nicotinamide is mediated by sodium ion-dependent facilitated diffusion. At higher concentrations, passive diffusion predominates with doses of 3 to 4 g of niacin being almost completely absorbed .
Toxicity
NOAEL is 4000mg. Inositol nicotinate can cause muscle pain, headache, redness of face, nausea, vomiting, edema and rash.
The Uses of Inositol nicotinate
myo-Inositol Hexanicotinate is an nicotinate conjugate of myo-inositol, an structural basis for a number of secondary messengers.
Background
Inositol nicotinate, also known as Inositol hexaniacinate/hexanicotinate or "no-flush niacin", is a niacin ester and vasodilator. It is used in food supplements as a source of niacin (vitamin B3), where hydrolysis of 1 g (1.23 mmol) inositol hexanicotinate yields 0.91 g nicotinic acid and 0.22 g inositol. Niacin exists in different forms including nicotinic acid, nicotinamide and other derivatives such as inositol nicotinate. It is associated with reduced flushing compared to other vasodilators by being broken down into the metabolites and inositol at a slower rate. Nicotinic acid plays an essential role in many important metabolic processes and has been used as lipid-lowering agent. Inositol nicotinate is prescribed in Europe under the name Hexopal as a symptomatic treatment for severe intermittent claudication and Raynaud’s phenomenon.
Indications
Indicated as a dietary supplement for the source of niacin. Has been investigated for potential beneficial effects on serum lipids. In Europe, inositol hexanicotinate is indicated as a patented drug known as Hexopal, which is therapeutically indicated for the symptomatic relief of severe intermittent claudication and Raynaud’s phenomenon.
What are the applications of Application
myo-Inositol hexanicotinate is a nicotinate conjugate of myo-inositol
Pharmacokinetics
Inositol nicotinate mediates a vasodilatory, lipid-lowering and fibrinolytic effect on the cardiovascular system. Like other niacins, inositol nicotinate is a lipid-regulating agent that reduces the levels of plasma triglycerides, atherogenic apolipoprotein B (apoB)-containing lipoproteins (VLDL, LDL and lipoprotein a) while increasing antiatherogenic apoA-I-containing HDL levels .
Metabolism
Inositol nicotinate undergoes hydrolysis by plasma esterases, releasing free nicotinic acid and inositol in a sustained manner. The process takes more than 48hours, where the bloodstream enzymatic hydrolysis of inositol hexanicotinate was found to be slower in the first ester linkage of inositol hexanicotinate than in subsequent linkages . Sequential hydrolytic steps of inositol nicotinate forms one nicotinic acid molecule in each step, producing eventually six molecules of nicotinic acid and one inositol moiety .
