Tadalista Super Active is a medication used to treat erectile dysfunction (ED) in men. It contains tadalafil as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5) in the smooth muscle cells of the penis. This inhibition leads to an increase in the levels of cyclic guanosine monophosphate (cGMP), a chemical messenger that helps relax smooth muscle tissue and dilate blood vessels in the penis.
