How does Cialis work ?

Cialis is known as the weekend drug because its effects last for about 36 hours after it has been taken. It has been observed during clinical trials that Cialis drug works much faster than Viagra and men who take Cialis pill are able to have sex within 30 minutes. Hence buying Cialis online is a better option as compared to other drug, Viagra.

The normal physical response on being sexually excited in men is increased blood flow to the penis, which results in erection.

Cialis blocks enzymes called phosphodiesterase - 5 Or PDE-5, which results in the widening and relaxing of the smooth muscles in the penis causing an erection. Thus, a male patient with ED can have a satisfactory erection and perform sexual activity with ease. After having sex and achieving orgasm, the blood flow to the penis is decreased and the erection subsides.
