In addition, Tadalafil Tablets India is approximately 700 times more active against PDE5 than against PDE6 found in the retina and responsible for photo transmission. Tadalafil Tablets Usp 20 Mg is also showing the action in 9000 times more potent against PDE5 compared to its effect on PDE8, PDE9 and PDE10, and 14 times more potent against PDE5 compared to PDE11.
