<p>The malegra 100mg is a medication containing 100 milligrams of sildenafil citrate. Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor commonly used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, allowing for a stronger and longer-lasting erection during sexual stimulation. When a man is sexually aroused, sildenafil citrate helps relax the blood vessels in the penis, promoting a better circulation of blood. This improved blood flow is vital for achieving and sustaining an erection, enabling a satisfying sexual experience.</p>
