A key role for histamine in the physiological control of gastric acid secretion was established with the advent of the histamine H2-receptor antagonists which have in vivo been shown to inhibit virtually all forms of basal and stimulated secretion.' These data can be seen to support the common mediator hypothesis championed in the last three decades by Code2 3 and which states that secretory st...

BACKGROUND Urticaria produces weals, which are itchy and can affect the quality of life and social functioning of an affected patient. There are several different subtypes of urticaria. This article focuses on chronic urticaria. OBJECTIVE This article details the approach to assessment and management of chronic urticaria. DISCUSSION Chronic urticaria is characterised by the occurrence of we...

A clinical drug-drug interaction between famotidine (a H2 receptor antagonist) and probenecid has not been reproduced in rats. The present study hypothesized that the species-dependent probenecid sensitivity is due to a species difference in the contribution of renal organic anion and cation transporters. The transport activities of the H2 receptor antagonists (cimetidine, famotidine, and ranit...

Histamine (10-7 to 10-4 M) concentration-dependently stimulated the production of IL-18 and IFN-gamma and inhibited the production of IL-2 and IL-10 in human PBMCs. Histamine in the same concentration range did not induce the production of IL-12 at all. The stimulatory or inhibitory effects of histamine on cytokine production were all antagonized by H2 receptor antagonists ranitidine and famoti...

Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal disorders, and the pharmacological management of GERD is a topic of intense interest given the sizeable yearly expenditure for antireflux therapies. GERD is primarily a motor disorder of the esophagus, yet pharmacological approaches directed at altering esophageal motility have been only partially effective. Antis...

the aim of this study was to assess the effects of exogenous histamine and h1 and h2 central receptorson electrocardiographic (ecg) parameters, heart rate and mean electrical axis in broiler chickens. for thispurpose, ross broiler chickens (750-800 g weight) received intracerebroventricularly (icv) histamine.moreover, to determine the receptors involved in histamine-induced alterations in ecg c...
