Alfuzosin hydrochloride (Alfuzosin HCl) is an α1 adrenergic receptor antagonist. It applies to treat benign prostatic hyperplasia (BPH).

Alfuzosin (SL 77499) is an orally available, competitive α1-adrenoceptor antagonist.Alfuzosin induces smooth muscle relaxation in the bladder neck and prostate.Alfuzosin has been used to study benign prostatic hypertrophy, lower urinary tract symptoms (LUTS), and ejaculatory dysfunction (EjD).

BQ-3020 ammonium, a selective endothelin receptor (ET B receptor) agonist, demonstrates inhibition of [125 I] ET-1 binding to ET B receptors with an IC50 of 0.2 nM and induces vasoconstriction in rabbit pulmonary arteries. Additionally, it promotes relaxation of the pig urinary bladder neck, rendering it useful for research into cardiovascular diseases [1] [2].

Tamsulosin ((R)-(-)-YM12617 free base) is an alpha1A adrenergic receptor antagonist used for the symptomatic treatment of benign prostatic hyperplasia (BPH). It treats difficulty urinating, a common symptom of an enlarged prostate, by relaxing the neck muscles of the bladder and muscle fibers in the prostate itself, easing urination.
