Malegra Professional contains sildenafil citrate as its active ingredient. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor, which works by increasing blood flow to the penis during sexual stimulation, thereby helping to achieve and maintain an erection. Malegra Professional comes in the form of sublingual tablets, which are designed to be placed under the tongue and allowed to dissolve. This allows for faster absorption into the bloodstream compared to traditional oral tablets, leading to quicker onset of action. https://www.genericday.com/malegra-professional.html
