Applications:
Tadalafil is a PDE5 inhibitor marketed in pill form for treating erectile dysfunction (ED) under the name Cialis, and
under the name Adcirca for the treatment of pulmonary arterial hypertension.
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. |
