Malegra 25 mg is a medication containing sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. It is primarily used to treat erectile dysfunction (ED), a condition characterized by the inability to achieve or maintain an erection sufficient for sexual activity. Sildenafil citrate works by inhibiting the enzyme PDE5, which is responsible for the degradation of cyclic guanosine monophosphate (cGMP) in the corpus cavernosum of the penis. By inhibiting PDE5, sildenafil citrate helps to increase levels of cGMP, which in turn relaxes the smooth muscles of the blood vessels in the penis, allowing for increased blood flow. This enhanced blood flow facilitates the achievement and maintenance of an erection during sexual stimulation. https://www.flatmeds.com/product/malegra-25-mg/
