Suhagra 50 is a medication that contains the active ingredient Sildenafil citrate. It is primarily used to treat erectile dysfunction (ED), a condition characterized by the inability to achieve or maintain an erection during sexual activity. Sildenafil citrate, the main component of Suhagra 50, belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by relaxing the blood vessels in the penis, allowing for increased blood flow, which helps to facilitate an erection.
