Description:
Tadalafil is cyclic guanosine monophosphate (cGMP) specific phosphodiesterase type 5 (PDE5) selective, reversible inhibitor, when stimulation leads to local release of nitric oxide, PDE5 inhibition by tadalafil, to improve the level of intracavernous cGMP, which leads to smooth muscle relaxation, blood flows into the penile tissue, produce an erection, such as sexual stimulation.
Application:
Although sildenafil (Viagra), vardenafil (Levitra), and tadalafil (Cialis) all work by inhibiting PDE5, tadalafil's pharmacologic distinction is its longer half-life (17.50 hours) - compared to sildenafil (4.0-5.0 hours) and vardenafil (4.0-5.0 hours) - resulting in longer duration of action, and so partly responsible for "The Weekend Pill" sobriquet. Furthermore, the longer half-life is the basis for current investigation of tadalafil's daily therapeutic use in relieving pulmonary arterial hypertension. Sildenafil is approved in several world regions as a thrice-daily therapy for pulmonary arterial hypertension.
