Fildena double 200mg contains Sildenafil Citrate, the same active ingredient found in Viagra. Sildenafil belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors, which work by relaxing the blood vessels in the penis. This increased blood flow helps men achieve and maintain an erection when sexually stimulated. It is important to note that Fildena 200 does not cause automatic erections; sexual arousal is still necessary for it to work effectively.
