Prescription nicotinic acid was shown to cause hepatotoxicity [16] and increase risk of type 2 diabetes. [17] [18] nicotinic acid prescriptions in the U.S. had peaked in 2009 at 9.4 million, declining to 800 thousand by 2020. [19] Nicotinic acid has the formula C 6 H 5 NO 2 and belongs to the group of the pyridinecarboxylic acids. [5]
Example of a label showing the amount of niacin (Vitamin B3), and specifying to be niacinamide in the ingredient section.. The United States Government adopted the terms niacin and niacinamide in 1942 as alternate names for nicotinic acid and nicotinamide, respectively, and encouraged their use in nontechnical contexts to avoid the public’s confusing them with the nearly unrelated (and toxic ...
A nicotinic agonist is a drug that mimics the action of acetylcholine (ACh) at nicotinic acetylcholine receptors (nAChRs). The nAChR is named for its affinity for nicotine. Examples include nicotine (by definition), acetylcholine (the endogenous agonist of nAChRs), choline, epibatidine, lobeline, varenicline and cytisine. [1]
The final step in the synthesis of nicotine is the coupling between N-methyl-Δ 1-pyrrollidium cation and nicotinic acid. Although studies conclude some form of coupling between the two component structures, the definite process and mechanism remains undetermined.

It is an amide of nicotinic acid. [7] As an aromatic compound, it undergoes electrophilic substitution reactions and transformations of its two functional groups. Examples of these reactions reported in Organic Syntheses include the preparation of 2-chloronicotinonitrile by a two-step process via the N-oxide, [23] [24]
Laropiprant was a drug used in combination with nicotinic acid to reduce blood cholesterol (LDL and VLDL) that is no longer sold, due to increases in side-effects with no cardiovascular benefit. Laropiprant itself has no cholesterol lowering effect, but it reduces facial flushes induced by nicotinic acid.
Arecoline (/ ə ˈ r ɛ k ə l iː n /) is a nicotinic acid-based mild parasympathomimetic stimulant alkaloid found in the areca nut, the fruit of the areca palm (Areca catechu). [2] It is an odourless oily liquid. It can bring a sense of enhanced alertness and energy along with mild feelings of euphoria and relaxation.
