Vidalista 20 mg contains 20 milligrams of tadalafil per tablet. This dosage strength is considered a standard dose and may be suitable for many men with erectile dysfunction. However, dosage adjustments may be made based on individual response and tolerance. Tadalafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for breaking down cyclic guanosine monophosphate (cGMP). By inhibiting PDE5, tadalafil helps to increase the levels of cGMP, which relaxes the smooth muscles of the blood vessels in the penis, allowing for increased blood flow and resulting in an erection when sexually stimulated.
