Danafil 50 mg Tablet

Also Available :100 mg25 mg


Danafil 50 mg tablet is a preparation of sildenafil (as citrate form). Sildenafil is an oral therapy for erectile dysfunction. The physiologic mechanism of erection of the penis involves the release of nitric oxide (NO) in the corpus cavemosum during sexual stimulation. No then activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (CGMP), producing smooth muscle relaxation in the corpus cavernosum and allowing inflow of blood, Sildenafil has no direct relaxant effect on isolated human corpus cavernosum but enhances the effect of nitric oxide (NO) by inhibiting phosphodiesterase type 5 (PDES), which is responsible for degradation of cGMP in the corpus cavernosum results in increased levels of cGMP in the corpus cavernosum, resulting in smooth muscle relaxation and inflow of blood to the corpus cavernosum. Sildenafil at recommended doses has no effect in the absence of sexual stimulation.

Sildenafil metabolism is principally mediated by the cytochrome P450 (CYP) isoforms 3A4 (major route) and 2C9 (minor route). Therefore, inhibitors of these isoenzymes may reduce sildenafil clearance and inducers of these isoenzymes may increase sildenafil clearance.



Sildenafil was shown to potentiate the hypotensive effects of nitrates, and its administration to parents who are using organic nitrates, either regularly and/or Intermittently, in any form is therefore contraindicated.

Therefore, treatments for erectile dysfunction, including sildenafil, should not be generally used in men for whom sexual activity is inadvisable because of their underlying cardiovascular status, Caution is advised when Sildenafil co-administered with alpha-blockers. Sildenafil and alpha-adrenergic blocking agents are both vasodilators with blood pressure lowering effects, The concomitant administration of the protease inhibitor ritonavir substantially increases serum concentrations of sildenafil (11-fold increase in AUC). Sildenafil is prescribed to patients taking ritonavir, caution should be used In the event of an erection that persists longer than 4 hours, the patient should seek immediate medical assistance. If priapism is not treated immediately, penile tissue damage and permanent loss of potency could result.
