Niacinamide / Nicotinamide
(Vitamin B3 / Vitamin PP)
Nicotinamide, also known as niacinamide and nicotinic acid amide, is the amide of nicotinic acid (vitamin B3). Nicotinamide is a water-soluble vitamin and is part of the vitamin B group.
Nicotinamide has demonstrated anti-inflammatory actions which may be of benefit in patients with inflammatory skin conditions. These conditions include acne vulgaris, and the compound can suppress antigen induced-lymphocytic transformation and inhibit of 3'-5' cyclic AMP phosphodiesterase. Nicotinamide has demonstrated the ability to block the inflammatory actions of iodides known to precipitate or exacerbate inflammatory acne.
Animal studies show that nicotinamide has anti-anxiety (anxiolytic) properties. It may work in a way similar to benzodiazepines.
Nicomide (take note the naming similarity), is an acne medication, and in its vitamin supplement form, the most predominant ingredient is 750 mg of nicotinamide, based on this area of research.
Nicotinamide lacks the vasodilator, gastrointestinal, hepatic, and hypolipemic actions of nicotinic acid. As such nicotinamide has not been shown to produce the flushing, itching and burning sensations of the skin as is commonly seen when large doses of nicotinic acid are administered orally. However, nicotinamide can produce liver toxicity at high doses.[6] In overall, it rarely causes side effects, and is considered generally safe as a food additive, component in cosmetics and medication.[7]
Nicotinamide is produced by the aqueous ammonolysis of 3-cyanopyridine (nicotinonitrile) and subsequent crystallisation.
