Fildena Professional is a medication designed to treat erectile dysfunction. Manufactured by Fortune Healthcare, it is known for its reliability and effectiveness. The active ingredient in Fildena Professional is Sildenafil Citrate, the same component used in Viagra, ensuring its efficacy in treating ED. The primary ingredient in Fildena Professional is Sildenafil Citrate. This compound works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which regulates blood flow in the penis. By blocking this enzyme, Sildenafil Citrate enhances blood flow, helping to achieve and maintain an erection during sexual activity.
