Yes, the pharmacological component in Fildena 100mg is Sildenafil Citrate, which is the same active ingredient found in Viagra. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor. It works by relaxing the blood vessels in the penis, allowing more blood to flow into the area, thus helping to achieve and maintain an erection during sexual arousal. Sildenafil inhibits the enzyme PDE5, which normally breaks down cyclic GMP (cGMP). cGMP is responsible for relaxing the smooth muscle cells and widening blood vessels in the penis. By inhibiting PDE5, sildenafil increases the levels of cGMP, leading to increased blood flow to the penis during sexual stimulation.
