Histamine Hj antagonists

Histamine Hj-antagonists such as cimetidine or ranitidine can be heipfu when combined with H,-antihistamines... [Pg.204]

Action on organs other than the target organ (e.g., peripheral tachycardic and hypertensive effects of dopamine after systemic application of the anti-Parkinson drug L-dopa, sedative side effects of lipophilic histamine Hj antagonists). [Pg.43]

Olopatadine hydrochloride is an ophthalmic antihistamine that inhibits release of histamine from mast cells and is a relatively selective histamine Hj antagonist. It inhibits type 1 inunediate hypersensitivity reactions. Olopatadine hydrochloride is indicated in the temporary relief of itching caused by allergic conjunctivitis. Hj antagonists have an... [Pg.513]

Antihistamines (histamine Hj-antagonists) vary in their interaction profiles by sedative potential, route of metabolism, and eardiotoxieity (QT interval prolongation). [Pg.582]

Another antiulcer histamine Hj receptor antagonist containing a thiazole moiety is zalb-dine (131) Its synthesis can be accomplished readily by brominating 4 acetyl 2 methylimidazole (129) to give haloketone 130 Displacement with amidinothiourea completes the synthesis of zaltidme (131) via a displacement cyclodehydration sequence [45]... [Pg.95]

Antihistamine drags are classified as antagonists of Hj and receptors, and quantitatively speaking Hj antagonists dominate. Moreover, the term antihistamine drag is associated more with Hj antagonists. H2 blockers exhibit a specific effect on histamine receptive sites located in walls of the stomach and they significantly increase secretion of hydrochloric acid. [Pg.220]

Stimulation of gastric acid secretion is the most important response it is blocked only by Hj antagonists. As mentioned before, the hormone gastrin may be involved in histamine release, because Hj antagonists block gastrin-induced acid secretion. [Pg.265]
