Terazosin hydrochloride

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

Abbott (USA)

An α-1-adrenergicblocker related to prazosin.

Hytrin (Abbott).

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.

Terazosin is INN and BAN;HEITRIN.

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.

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 .

α1-adrenoceptor antagonist.
