Terazosin hydrochloride Structural

What is Terazosin hydrochloride?

Description

Terazosin hydrochloride is a highly water-soluble antihypertensive agent with a structure and profile closely related to that of prazosin.

Originator

Abbott (USA)

The Uses of Terazosin hydrochloride

Terazosin hydrochloride has been used for orthogonality and similarity analysis using reversed-phase chromatographic studies5. Furthermore, terazosin has also been used for the evaluation of chemometric techniques to determine orthogonality and similarity in chromatographic methods6.

The Uses of Terazosin hydrochloride

Hytrin (Abbott).

The Uses of Terazosin hydrochloride

An α-1-adrenergicblocker related to prazosin.

What are the applications of Application

Terazosin hydrochloride is an α1- and α2B-adrenoceptor antagonist

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.
