Fildena Double 200 mg contains 200 mg of sildenafil citrate, which is the same active ingredient found in popular ED medications like Viagra. Sildenafil is a PDE5 inhibitor that works by relaxing the blood vessels in the penis, allowing for increased blood flow and helping men with ED achieve and maintain an erection during sexual stimulation.
Sildenafil, the active ingredient in Fildena 200, increases blood flow to the penis by blocking the enzyme phosphodiesterase type 5 (PDE5). This enzyme typically breaks down a molecule called cyclic GMP, which is crucial for maintaining an erection. By inhibiting PDE5, sildenafil helps increase the levels of cyclic GMP, leading to enhanced blood flow and improved erectile function.
