Tadalafil Citrate

Alias: Tadalafei;Cialis

CAS No: 171596-29-5

MF: C22H19N3O4

MW: 389.41 

Purity: 99.5%

Appearance: white powder, odorless, tasteless, insoluble in water and alcohol.

Applications:

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.
