Background:

Doxazosin-d₈is intended for use as an internal standard for the quantification of doxazosin by GC- or LC-MS. Doxazosin is a non-selective antagonist of α₁-adrenergic receptors (α₁-ARs; K_is = 3.16, 1, and 3.98 nM for α_1A-, α_1B-, and α_1D-ARs, respectively).¹It inhibits norepinephrine-induced contractions in isolated rat aortic rings and human prostate strips with pA₂values of 8.8 and 8.2, respectively. Doxazosin inhibits phenylephrine-induced increases in blood pressure and prostatic pressure in anesthetized dogs (pA₂= 7.5 for both). Formulations containing doxazosin have been used in the treatment of benign prostatic hyperplasia and hypertension.
