Sildenafil Citrate, the active ingredient in Sildisoft tablets, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This inhibition leads to increased levels of cyclic guanosine monophosphate (cGMP), which relaxes smooth muscles in the blood vessels of the penis. This allows for increased blood flow when sexually stimulated, enabling an erection.
