A man's body releases nitric oxide in response to sexual excitement, which triggers the synthesis of cyclic guanosine monophosphate (cGMP) and relaxes the smooth muscles in the penis. An erection is the result of blood flowing into the penile tissues due to this relaxation. Nevertheless, phosphodiesterase type 5 (PDE5) breaks down cGMP too soon in men with ED, making it harder to get or keep an erection.
By inhibiting PDE5, Sildenafil Citrate 100 prolongs the effects of cGMP. By encouraging more blood flow to the penis, this action helps to achieve and maintain erections that are appropriate for engaging in sexual activity.
