Malegra Professional is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, the same active ingredient found in Viagra, but in a sublingual (under-the-tongue) form for faster absorption and quicker onset of action. Sildenafil citrate works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This causes the blood vessels in the penis to relax and expand, improving blood flow during sexual stimulation and allowing a firm, sustained erection.
