The science behind Tadalafil: buy tadalafil online canada

Tadalafil selectively inhibits PDE5, the enzyme that breaks down cGMP in smooth muscle cells, especially in the penile corpus cavernosum.

Sexual stimulation releases nitric oxide, which activates guanylate cyclase to produce cGMP from GTP. cGMP triggers smooth muscle relaxation and vasodilation, increasing blood flow for an erection.

By blocking PDE5, tadalafil slows cGMP breakdown, prolonging its action and improving erectile response, but only when nitric oxide is present (i.e., during arousal).

The same mechanism supports its effects in pulmonary arterial hypertension (pulmonary vessel relaxation) and benign prostatic hyperplasia (prostate and bladder neck smooth muscle relaxation).

Its ~17.5-hour half-life gives the long 36-hour window of activity that sets it apart from shorter-acting PDE5 inhibitors.
