Sildenafil citrate, the active ingredient in Sildigra Black Force 200 mg, works by inhibiting the enzyme phosphodiesterase type 5. This inhibition leads to increased levels of cyclic guanosine monophosphate (cGMP), a chemical that relaxes the smooth muscles in the blood vessels of the ****. This relaxation allows for improved blood flow to the ****, facilitating the ability to achieve and maintain an erection when ****ually aroused.
