Indications & Uses

Pharmacology

Tadalafil works by selectively blocking an enzyme called phosphodiesterase type 5 (PDE5). Blocking this enzyme raises levels of a signalling molecule called cGMP in smooth muscle cells. Higher cGMP relaxes smooth muscle and increases blood flow into the penis, which produces an erection.

PDE5 is also found in the smooth muscle of the prostate and bladder wall. By blocking PDE5 in these tissues as well, tadalafil raises cGMP levels there too, relaxing the smooth muscle of the prostate and bladder. This relaxation can improve blood flow to the urinary tract and help the bladder neck open more widely, making it easier to pass urine.
