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.

We tested an inexpensive controlled-release nicotinic acid product (Bronson Pharmaceuticals, LaCanada, CA) and compared it with the standard, more expensive, controlled release product, Nicobid (Rorer Pharmaceuticals), by measuring the 24 hour urinary recovery of nicotinic and nicotinuric acids from ten

The pharmacokinetics of nicotinic acid (NiAc) and nicotinuric acid (NiUAc), the major metabolite of NiAc, and the dose dependency of these pharmacokinetics were determined in rats. Intravenous injections of 2, 5, 15, and 45 mg/kg of NiAc and 5 and

The concentrations of nicotinic acid (NiAc) and nicotinuric acid (NiUAc), a major metabolite of NiAc, were simultaneously determined in urine using solid-phase extraction (cation-exchange extraction) and reversed-phase high-performance liquid chromatography with ultraviolet detection. The intra- and inter-day precision studies showed

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
