Filagra Oral Jelly is a medication used to treat erectile dysfunction (ED). It contains sildenafil citrate, the same active ingredient found in Viagra, but is available in a gel form that is absorbed more quickly. Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor. It blocks the PDE5 enzyme, leading to an increase in cyclic guanosine monophosphate (cGMP). This relaxes the smooth muscle in the blood vessels of the penis, enhancing blood flow and facilitating an erection in response to sexual stimulation.
