Viagra and tadalafil are both erectile dysfunction (ED) medications, but they work in different ways. Viagra is a phosphodiesterase type 5 (PDE5) inhibitor, while tadalafil is a PDE5-specific inhibitor. This means that tadalafil is more selective for the PDE5 enzyme, which is responsible for the breakdown of cyclic guanosine monophosphate (cGMP). cGMP is a molecule that helps to relax the smooth muscles in the penis, allowing for better blood flow and an erection.
Because
Tadalafil 60 is more selective for the PDE5 enzyme, it has a longer half-life than Viagra. This means that tadalafil can be taken up to 36 hours before sexual activity, while
Viagra needs to be taken within 60 minutes of sexual activity.
In terms of effectiveness, b oth Viagra and tadalafil are equally effective at treating ED. However, tadalafil may be a better option for men who want a longer-lasting erection.
