Fildena Super Active is typically taken 15–30 minutes before sexual activity, faster than standard Sildenafil tablets. Effects can last 4–6 hours, and the dosage should be determined by a healthcare professional based on individual health conditions. Only one dose should be taken per day. Sildenafil in Fildena Super Active is a phosphodiesterase type-5 (PDE5) inhibitor. During sexual stimulation, the body releases nitric oxide in the penile tissue, which increases levels of cyclic GMP (cGMP). https://www.genericday.com/fildena-super-active.html
