Yes, Fildena 100 mg can be an effective treatment for erectile dysfunction (ED). It contains Sildenafil Citrate, the same active ingredient found in well-known ED medications like Viagra. Sildenafil works by enhancing blood flow to the penis, helping men with ED achieve and maintain an erection when sexually stimulated. Fildena 100 mg works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow to the penis. By blocking this enzyme, Fildena 100 mg helps relax the blood vessels in the penis, allowing more blood to flow into the area, resulting in an erection when a man is sexually aroused. It does not cause an erection on its own but works in response to sexual stimulation.
