Aurogra 100 mg is a medication primarily used to treat erectile dysfunction (ED) in men. ED is a common condition characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. Aurogra 100 mg contains sildenafil citrate, a potent inhibitor of the enzyme phosphodiesterase type 5 (PDE5). This enzyme normally breaks down cyclic guanosine monophosphate (cGMP), a substance that regulates blood flow in the penis. By inhibiting PDE5, sildenafil helps to increase blood flow to the penis during sexual stimulation, facilitating the achievement and maintenance of an erection.
