| Cialis (tadalafil) is a medicine that has been licenced to treat male impotence, which is the recurrent inability to achieve or maintain an erection sufficient for sexual intercourse.
The recommended dose is 10 milligrams, but some men find 5 milligrams enough. In some cases a 20 mg dose is required. Cialis should be taken orally 30 minutes or more prior to sexual activity.
Clinical studies have shown that Cialis is efficacious in 60%-80% of cases. The majority of failure cases are reported in men who have undergone an operation that made having or sustaining an erection physically impossible.
When a man is aroused, nerve signals are sent from the brain to the genitals. Consequently, chemicals that relax the muscles in the penis are released. Ordinarily, these muscles are constricted and blood cannot flow into the penile area. When the muscles relax, larger amounts of blood are able to reach the penile area, leading to an erection. An erection is reversed when another chemical (usually called phosphodiesterase type 5 PDE5) attacks the chemicals that caused the muscles to relax earlier. This causes penile muscles to constrict again when blood leaves the genital area.
The medicine works by blocking PDE5. When PDE5 is blocked, more chemicals leading to an erection remain in the genital area, so the muscles in the penis do not narrow allowing blood to stay in the penis longer, which allows a man to maintain an erection.
Many males want to know if Cialis works without any arousal. The reply to this question is negative. This is because the chemicals that cause an erection need to be released into the penis. These chemicals get released only when a person is excited. Cialis does not effect the release of the chemicals. It only keeps the chemicals in the penis for a longer period.
According to the studies, Cialis starts to work in 30 minutes. Cialis can work up to 36 hours after the administration. Additionally, Cialis can be taken on an empty stomach or during a meal.
Cialis does not increase sexual drive and it will not lead to an erection during 36 hours. The vast majority of males who take the medication say that for up to 36 hours after taking the drug, an erection can be sustained provided the penis was aroused by touch. After an orgasm, the penis commonly returns to its pre-aroused state.
Some males can experience one or more orgasms after the first one, but this is an exception. In the vast majority of cases, during 36 hours after taking 20 milligrams of the drug, men are able to achieve and sustain an erection to climax one time.
The drug is available by prescription only. You can talk to your general practitioner about getting a prescription or you can buy Cialis on-line. A prescription will be issued by a physician after you fill in a questionnaire at the on-line drugstore selling the medication. Generic Cialis is identical to Cialis. |
