Vigora 50 mg is a medication used to treat erectile dysfunction (ED) in men. Its active ingredient is Sildenafil Citrate 50 mg, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Sildenafil works by relaxing the blood vessels in the penis, allowing increased blood flow during sexual stimulation, which helps men achieve and maintain an erection. When sexually stimulated, nitric oxide is released in the penis, leading to the production of cyclic GMP, which relaxes muscles and allows blood flow into the penile tissues.
