Hazard Information | Back Directory | [Description]
Terazosin hydrochloride is a highly water-soluble antihypertensive agent with a
structure and profile closely related to that of prazosin. | [Originator]
Abbott (USA) | [Uses]
Hytrin (Abbott). | [Brand name]
Terazosin
is INN and BAN;HEITRIN. | [General Description]
Terazosin hydrochloride, 1-(4-amino-6,7-dimethoxy-2-quinazolinyl)-4-(tetrahydro-2-furoyl)piperazine monohydrochloride (Hytrin), is a structuralcongener of prazosin hydrochloride. It possessessimilar selective properties of specifically inhibiting 1-adrenergic receptors. The drug is slightly less potent thanprazosin hydrochloride. Terazosin hydrochloride has a halflifeof approximately 12 hours, which is much longer thanthat of prazosin. This lends itself to a once-daily dose tocontrol hypertension in many patients. | [Biological Activity]
