Use | Alfuzosin HCl is an α1 receptor antagonist used in the treatment of benign prostatic hyperplasia (BPH). |
In vitro study | Alfuzosin significantly increased the whole-cell sodium ion (hNa(v)1.5) peak current, increased the probability of late hNa(v)1.5 the opening of a single channel, and significantly shortened the slow time constant for recovery from inactivation. Alfuzosin also increases hNa(v)1.5 burst duration and opening per burst between 2-and 3-fold. In 10 mM phenylephrine precontracted rabbit corpuscavernosum(CC), Alfuzosin showed a concentration-dependent relaxing effect. |
In vivo study | Alfuzosin(300 nM) significantly prolonged the action potential phase (APD) of rabbit Purkinje fibers (60) and QT of isolated rabbit hearts. In spontaneously hypertensive rats (SHR), Alfuzosin enhanced the number and amplitude of Apomorphine-induced erections. In spontaneously hypertensive rats (SHR), Alfuzosin behaves as an α-adrenergic receptor antagonist, blocking exogenous noradrenaline-induced contraction without altering vasdeferens vasoconstriction. In rats with spinal cord destruction, Alfuzosin(0.03-0.3 mg/kg, I. V.) significantly inhibited the pressor response produced by the α1-selective agonist, Cirazoline, but only slightly inhibited the response to the α2-selective agonist, UK 14,304. Alfuzosin(1 mg/kg, I. V.) had minimal effect on prejunctional α2-receptor stimulation-mediated responses (UK 14,304-induced inhibition of sympathetic tachycardia). In anesthetized cats, Alfuzosin(0.001 mg/kg, I. V.) and Prazosin(0.001-0.3 mg/kg, I. V.) produced a dose-related inhibition of sympathetic hypoabdominal nerve stimulation of the urethral pressure increase. |
