Gastric inhibitory effects of CM57755. A new histamine H2 receptor antagonist. 1986

J A Wilson, and D Johnston, and J Penston, and K G Wormsley

The gastric inhibitory effects of CM57755, a new histamine H2 receptor antagonist, have been compared in ten healthy male volunteers with the actions of an equal dose of cimetidine and with placebo. The inhibitory effect of CM57755 was virtually identical with, and not significantly different from the effects of cimetidine on nocturnal gastric secretion of acid, while neither drug influenced the secretion of pepsin. Neither drug, administered in the evening, influenced the intragastric pH and acidity during the following day, from breakfast onwards. The therapeutic impact of the new drug is likely to resemble that of cimetidine and clinical application will depend on the safety profile.

D008297 Male Males
D009536 Niacinamide An important compound functioning as a component of the coenzyme NAD. Its primary significance is in the prevention and/or cure of blacktongue and PELLAGRA. Most animals cannot manufacture this compound in amounts sufficient to prevent nutritional deficiency and it therefore must be supplemented through dietary intake. Nicotinamide,Vitamin B 3,Vitamin PP,3-Pyridinecarboxamide,Enduramide,Nicobion,Nicotinsäureamid Jenapharm,Papulex,Vitamin B3,3 Pyridinecarboxamide,B 3, Vitamin,B3, Vitamin,Jenapharm, Nicotinsäureamid
D010434 Pepsin A Formed from pig pepsinogen by cleavage of one peptide bond. The enzyme is a single polypeptide chain and is inhibited by methyl 2-diaazoacetamidohexanoate. It cleaves peptides preferentially at the carbonyl linkages of phenylalanine or leucine and acts as the principal digestive enzyme of gastric juice. Pepsin,Pepsin 1,Pepsin 3
D002927 Cimetidine A histamine congener, it competitively inhibits HISTAMINE binding to HISTAMINE H2 RECEPTORS. Cimetidine has a range of pharmacological actions. It inhibits GASTRIC ACID secretion, as well as PEPSIN and GASTRIN output.

D006635 Histamine H2 Antagonists Drugs that selectively bind to but do not activate histamine H2 receptors, thereby blocking the actions of histamine. Their clinically most important action is the inhibition of acid secretion in the treatment of gastrointestinal ulcers. Smooth muscle may also be affected. Some drugs in this class have strong effects in the central nervous system, but these actions are not well understood.
