 |  | Terazosin hydrochloride Usage And Synthesis |  
 | 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 | An α-1-adrenergicblocker related to prazosin. |  | Uses | Hytrin (Abbott). |  | Uses | 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. |  | 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. |  | storage | Store at RT |  | References | References/Citations
