Cialis helps men to get and maintain an erection when sexually stimulated and/or excited. The medicine relaxes the blood vessels in the penis which results in more blood flowing to the penis.

All these areas have shown PDE5 activity and are potential target of PDE5i action. Prostate smooth muscle relaxation, detrusor muscle overactivity, and contraction of prostate tissue can be inhibited through cGMP increase achieved by either NO donors or PDE5Is. Additionally, PDE5i (including tadalafil, sildenafil, or the NO donor sodium nitroprusside) have been shown to attenuate α-adrenergic-induced contraction of isolated human prostate tissue. Thus cGMP may contribute to the regulation of prostatic smooth muscle cell contraction.
