Fildena 200 Tablets, a medication containing sildenafil citrate, functions as a potent phosphodiesterase type 5 (PDE5) inhibitor. In cases of erectile dysfunction (ED), the blood vessels in the penile region may constrict, hindering proper blood flow and causing difficulties in achieving and sustaining an erection. Fildena combats this by inhibiting the PDE5 enzyme's action, which would normally break down cyclic guanosine monophosphate (cGMP), a chemical responsible for relaxing blood vessels and facilitating blood flow. By maintaining higher cGMP levels, Fildena promotes enhanced blood circulation to the penis, enabling firmer and longer-lasting erections, ultimately assisting in the management of ED.
