bladder neck

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).

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

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 for the symptomatic treatment of benign prostatic hyperplasia (BPH). Tamsulosin is used to treat difficulty urinating, a common symptom of an enlarged prostate. Tansulosin and other drugs called alpha blockers work by relaxing the neck muscles of the bladder and muscle fibers in the prostate itself, making it easier to urinate.
