| Cialis (tadalafil) is a drug that has been licensed to treat erectile dysfunction, which is the repeated inability to get or sustain an erection sufficient for sexual activity.
It was first invented in February 2003 and it was approved by the U.S. Food and Drug Administration on November 21, 2003.
The recommended dose is 10 milligrams, but some men find 5 milligrams enough. In some cases a 20 milligram dose is required. Cialis is taken orally 30 minutes or more before intimacy.
Various trials have proved that the medication is efficient in 60%-80% of cases. Most failure cases are reported in males who have undergone an operation that made attaining or sustaining an erection physically impossible.
When a male is aroused, nerve signals are sent from the brain to the penis. Consequently, chemicals that relax the muscles in the penis get released. Usually, these muscles are narrowed and blood cannot stream into the penis. When the muscles relax, more blood is able to reach the genital area, triggering an erection. An erection is reversed when another chemical (usually called phosphodiesterase type 5 PDE5) inhibits the chemicals that triggered the muscles to relax earlier. This causes the muscles in the penis to narrow again as blood leaves the penis.
The medicine works by inhibiting PDE5. When PDE5 is blocked, more chemicals triggering an erection remain in the genitals, so penile muscles do not constrict allowing blood to stay in the genitalia for a longer period of time, which allows a male to sustain an erection.
A lot of men wonder if Cialis works without any arousal. The reply to this question is negative. This is because the chemicals that lead to an erection need to be released into the penis. These chemicals get released only when a person is aroused. The drug does not impact upon the release of these chemicals. It only keeps the chemicals in the penis longer.
In various tests, Cialis starts to work in 30 minutes. Cialis can work up to 36 hours from the time you take the medication. In addition, Cialis can be taken on an empty stomach or during a meal.
Cialis does not increase libido and it will not lead to an erection within 36 hours. Most males who take Cialis admit that for up to 36 hours after taking the medication, an erection can be maintained provided the penis was aroused by touch. After an orgasm, the penis ordinarily returns to its pre-excited state.
Cialis is available by prescription only. You can talk to your general practitioner about getting a prescription or you can order Cialis on the Web. A prescription will be issued by a general practitioner after you complete a questionnaire at the online pharmacy selling the medication. Generic Cialis is identical to Cialis. |
