Ranitidine: a new H2-receptor antagonist.
The pharmacology, pharmacokinetics, clinical efficacy, adverse reactions, drug interactions, and dosage of ranitidine are reviewed; specific comparisons are made of this new H2-receptor antagonist with the older agent, cimetidine. Ranitidine is a potent inhibitor of gastric acid secretion whose chemical structure lacks the imidazole group previously believed to be essential for H2-receptor bloc...
متن کاملThe pharmacology of atracurium: a new competitive neuromuscular blocking agent.
Atracurium besylate, 2,2'-(3,11-dioxo-4,10-dioxatridecylene)-bis-[6,7-dimethoxy-1-(3,4-dimethoxy-benzyl)-2-methyl-1,2,3,4-tetrahydroisoquinolinium] dibenzenesulphonate, is one of a new series of competitive neuromuscular blocking agents. An i.v. dose of 0.25 mg kg-1 produced complete paralysis in anaesthetized cats, dogs and rhesus monkeys; paralysis was of medium duration and was readily antag...
متن کاملHistamine H2-receptor antagonist ranitidine protects against neural death induced by oxygen-glucose deprivation.
BACKGROUND AND PURPOSE Administration of histamine receptor antagonists has been reported to produce contradictory results, either reducing or increasing neural damage induced by ischemia. In this study, we investigated the neuroprotective effects of histamine H2-receptor antagonists in an "in vitro" model of ischemia. METHODS Cultured rat brain cortical neurons were exposed to oxygen-glucose...
متن کاملHistamine H2 receptor trafficking: role of arrestin, dynamin, and clathrin in histamine H2 receptor internalization.
Agonist-induced internalization of G protein-coupled receptors (GPCRs) has been implicated in receptor desensitization, resensitization, and down-regulation. In the present study, we sought to establish whether the histamine H2 receptor (H2r) agonist amthamine, besides promoting receptor desensitization, induced H2r internalization. We further studied the mechanisms involved and its potential r...
متن کامل[Structural analysis of the histamine H2 receptor].
In gastric parietal cells the histamine H2 receptor is involved in gastric acid secretion. Molecular cloning of the cDNA for the histamine H2 receptor has revealed that the receptor is a member of the G-protein coupled receptor family. We expressed histamine H2 receptors in CHO cells, COS7 cells, and Sf9 cells to analyze N-glycosylation, palmitoylation, and desensitization of the H2 receptor, w...
