Mechanism of Action

Tamsulosin is a selective α1 adrenoreceptor-blocking agent. Smooth muscle tone is mediated by the sympathetic nervous stimulation of α1 adrenoreceptors, which are abundant in the prostate, prostatic capsule, prostatic urethra, and bladder neck. Blockade of these adrenoceptors can cause smooth muscles in the bladder neck and prostate to relax, resulting in an improvement in urine flow rate and reduction in symptoms in BPH.

Metabolism: Metabolised slowly in the liver primarily by CYP2D6 and CYP3A4. Excretion: Excreted in urine (76%) and faeces (21%).
