| Cialis (tadalafil) is a drug that has been accredited to treat sexual dysfunction, which is the repeated inability to achieve or keep an erection sufficient for intimacy.
Various tests have proved that the drug is potent in 60%-80% of cases. The majority of failure cases are in men who have undergone a surgery that made having or maintaining an erection physically impossible.
Cialis works by blocking a chemical called phosphodiesterase type 5.
When a male gets sexually excited, the medicine triggers cells in the penis to produce nitric oxide. The growth in nitric oxide will in turn result in the production of cyclic guanosine monophosphate (cGMP). The cGMP causes arteries in the penis to relax and allow more blood to run through them. The increase in blood flow results in an erection.
If the enzyme phosphodiesterase type 5 (PDE5) is of sufficient quantity, it will attack the cGMP and erection will not be sustained. Cialis and other PDE5 inhibitors reduce the amount of PDE5 attacking the cGMP. If the amount of PDE5 is lower, most men are able to maintain an erection to orgasm.
In the vast majority of cases Cialis is effective 24-36 hours after the administration. Some males are especially enthusiastic about the fact that Cialis works for up to 36 hours and allows a man and his sexual partner to relax, forget about planning sexual intercourse and let things happen unarranged. In addition, Cialis can be taken on an empty stomach or during a meal.
Cialis does not better libido and it will not cause an erection during 36 hours. The majority of men who take Cialis admit that for up to 36 hours after taking Cialis, an erection can be maintained if provided the penis was aroused by touch. After an orgasm, the penis normally returns to its pre-excited state.
Cialis is available by prescription only. You can talk to your doctor about getting a prescription or you can buy Cialis on the Internet. A prescription will be issued by a medical practitioner after you fill out a medical form at the on-line drugstore offering the medication. The only drug that works exactly like Cialis is Generic Cialis. |
