Abstract
The effect of nicotinic acid on gastric secretion was studied in 19 fasting patients who had coronary heart disease and hyperlipoproteinemia. Among 10 patients with basal secretion of acid, 9 had increased acid output following oral administration of 0.5 g of nicotinic acid — the increase ranged from 13 to 232 per cent. Also in Pavlov pouch dogs, i.v. infusion of nicotinic acid gave rise to a significant increase in gastric acid output. The mechanism behind gastric stimulatory action of nicotinic acid is unknown.
