Nicotinic acid was first synthesized in 1867 by oxidative degradation of nicotine with potassium chromate and sulfuric acid [63] — this is the origin of the name. [16] Nicotinic acid is prepared by hydrolysis of nicotinonitrile, which, as described above, is generated by oxidation of 3

The LD 50 of nicotine is 50 mg/kg for rats and 3 mg/kg for mice. 0.5–1.0 mg/kg can be a lethal dosage for adult humans, and 0.1 mg/kg for children. [19] [20] However the widely used human LD 50 estimate of 0.5–1.0 mg/kg was questioned in a 2013 review, in light of several documented cases of humans surviving much higher doses; the 2013 review suggests that the lower limit causing fatal ...
Inositol nicotinate is generally safe when taken by mouth, but possible side effects include: Stomach upset; Intestinal gas; Nausea; Liver damage (similar to other niacin products) [1] It is marketed as "no-flush" niacin, but research suggests that the lack of flushing may be due to its limited conversion to active niacin. [4]
Nicotinyl alcohol (pyridylcarbinol) is a niacin derivative used as a hypolipidemic agent and as a vasodilator.It causes flushing and may decrease blood pressure. [2]It appears as a crystal that dissolves in water and alcohol with ease, also soluble in ether; melting range 147–148 °C.
Nikethamide is a stimulant which mainly affects the respiratory cycle. Widely known by its former trade name of Coramine, it was used in the mid-twentieth century as a medical countermeasure against tranquilizer overdoses, before the advent of endotracheal intubation and positive-pressure lung expansion.
