Mechanism of Action for PDE-5 Inhibitors (Viagra, Levitra, Cialis)
inhibits cGMP-specific PDE-5 enzyme that degrades cGMP in the corpus cavernosum. They enhance the effect of nitric oxide (NO) by inhibiting PDE-5 thereby increasing conc of cGMP which leads to relaxation of smooth muscle and flow of blood to the penis.
When should a man take a PDE-5 Inhibitor?
1 hour before intercourse
What is the caution for pilots taking Viagra, Levitra, or Cialis?
Alters blue-green colors, do not use 1 to 2 days before flying
