Malegra Oral Jelly increases blood flow to the penis to help men with erectile dysfunction (ED) achieve and maintain an erection during sexual stimulation. Here’s how it works in simple terms: Active ingredient — sildenafil citrate: This is the same medicine found in Viagra® and other ED treatments. It belongs to a class called PDE-5 inhibitors. Mechanism: Sildenafil blocks the phosphodiesterase type 5 (PDE5) enzyme. Normally, PDE5 breaks down a molecule called cGMP that helps relax smooth muscle in penile blood Malegra Oral Jelly . When PDE5 is blocked, cGMP stays active longer. Relaxed blood vessels allow more blood to flow into the erectile tissues of the penis during sexual arousal, leading to a firmer and longer-lasting erection. It’s important to know that Malegra Oral Jelly doesn’t cause an erection on its own — sexual stimulation is still required for the increased blood flow to produce an erection. The jelly form often absorbs faster than tablets, so many men notice effects within 15–30 minutes.
