Fildena is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient Sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil works by increasing blood flow to the penis, facilitating the ability to achieve and maintain an erection when sexually aroused.The effects of Sildenafil, such as those in Fildena, typically last for about 4 to 6 hours. This provides a window of opportunity for sexual activity within that time frame.
