Kamagra 100 mg contain sildenafil, which increases blood flow to the erectile tissue of the penis, causing an erection. Nitric oxide is released in the erectile tissue of the penis during sexual stimulation, which activates the enzyme granulate cyclase. This enzyme causes an erection by increasing the amounts of a substance called cyclic guanosine monophosphate (cGMP), Fildena relaxes the blood arteries in the penis and allows blood to fill the spongy erectile tissues. Phosphodiesterase type 5 (PDE5) is another enzyme that breaks down cGMP, restricting blood flow into the penis and resulting in erection loss. PDE5 inhibition by Kamagra 100 mg and Vidalista 40 mg relieves erectile dysfunction by allowing the normal process of sexual stimulation to activate the cGMP mechanism, which is responsible for establishing and sustaining an erection.
