Malegra Professional is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. Sildenafil citrate works by increasing blood flow to the penis during sexual stimulation, which helps men achieve and maintain an erection. Malegra Professional is primarily used to treat erectile dysfunction, a common condition characterized by the inability to achieve or maintain an erection sufficient for sexual activity. Sildenafil citrate helps improve erectile function by enhancing the natural response to sexual stimulation. Malegra Professional is formulated as a sublingual tablet, which means it is placed under the tongue where it dissolves and is absorbed directly into the bloodstream.
