Biochem/physiol Actions

Nicotinuric acid (NUA) is a metabolite of niacin/vitamin B. Measurement of NUA levels in urine is used to indicate possible elevated nicotinamide adenine dinucleotide (NAD) catabolism. NUA may be used as a reference (standard curve) in the analysis of NAD and NUA catabolism. Nicotinic acid reduces triglycerides and increases high density lipoprotein(HDL) cholesterol.

The mechanism of tolerance to nicotinic acid flushing was determined in subjects during a 5-day course of treatment. Objective measures of skin blood flow were used to confirm the development of tolerance. Plasma levels of nicotinic acid showed marked intraindividual

Both nicotinic acid and salicylic acid undergo glycine conjugation in human beings. Competitive inhibition may therefore be possible when these substances are used concomitantly in patients with hyperlipidemic disorders. The aim of this study was to determine, in six healthy
