Description
Terazosin hydrochloride is a highly water-soluble antihypertensive agent with a
structure and profile closely related to that of prazosin.
Uses
An α-1-adrenergicblocker related to prazosin.
Uses
Terazosin hydrochloride has been used for orthogonality and similarity analysis using reversed-phase chromatographic studies
5. Furthermore, terazosin has also been used for the evaluation of chemometric techniques to determine orthogonality and similarity in chromatographic methods
6.
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
α 1 - and α 2B -adrenoceptor antagonist (K i values are 3.3, 0.7, 1.1, 7.7, 1510 and 78.2 nM for α 1A , α 1B , α 1D , α 2B , α 2A and α 2C receptors respectively). Antihypertensive following oral or intravenous administration in vivo .
Biochem/physiol Actions
α1-adrenoceptor antagonist.
