Fildena CT 100 mg is a prescription medicine used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor that increases blood flow to the pill during sexual stimulation, helping achieve and maintain an erection. During sexual arousal, the body releases nitric oxide, which increases levels of cGMP. This relaxes blood vessels in the pill and improves blood flow. Sildenafil helps prevent the breakdown of cGMP, supporting a stronger and more sustained erection when sexually stimulated. https://www.genericday.com/fildena-ct-100-mg.html
