The introduction of Tadalafil in the market has brought a great change in the way Erectile Dysfunction is treated, and has able many suffering from Impotence, to have the freedom of choosing the best time for their sexual performance. The action of Tadalafil, better known as the â€Weekend pillâ€, and marketed under the name of “Cialisâ€, has a prolonged inhibitory power of up to 36 hours, making it the Erectile Dysfunction tablet with the longest lasting power on the market today.
Tadalafil goes to work in approximately thirty minutes, and is not affected by food digestion, therefore meals are not required to be planned according with the assumption of the drug. Once it is absorbed in the organism, the action of Tadalafil precludes the enzyme PDE5 from its preventive action on the cyclic GMP, which is triggered by sexual desire.
During the process of the erection, sexual stimulations produce the forming of cyclic GMP responsible for the increase of blood flow in the corpus cavernous of the smooth muscle, flooding the smooth muscle and resulting in the erection and harden of the penis. The action of Tadalafil focuses on the inhibition of the enzyme PDE5, which would other ways stop the cyclic GMP from performing the enlargement of the blood vessels. By focusing its action only on the specific enzyme PDE5, Tadalafil don’t interfere with the way a natural erection occurs, in fact, during the inhibitory action of Tadalafil on the enzyme PDE5, erections are only taking place when generate by sexual desire.
A pill can be taken in the evening of the Friday, and perform up until Sunday morning, giving who suffers from Erectile Dysfunction, the possibility to live their sexual life with the freedom to choose when the time is right, or to be ready whenever is needed. Tadalafil was put on the market after its FDA approval in November 2004, and following a testing trial that include a total of seven research centers.
The research trial included subjects suffering from various levels of impotence and other medical conditions, to study the effect of the inhibitory action on different combinations of medical disorders. During the four weeks study, the drug effect remained unchanged, and none of the pathologies that the subjects tested had suffered a degeneration of the condition.
The age of the subject undergoing the study was 59 in average and all tests were done in double-blinded, placebo-controlled trials that took place in several centers randomly picked both, internationally, and in the United States.
Two of those multi-centers were in US and tested a total of 402 subjects; the total of subjects studied among the totality of the trial studies was over 4,000 individuals. The study also showed that the action of Tadalafil on the specific PDE5 enzyme, is 10,000 more potent than on other enzymes that are used for the functioning of other organs, including the PDE1, PDE2, PDE4, and PDE7 enzymes, which are found in vital organs like the heart, brain, blood vessels, liver, leukocytes, skeletal muscle, and other organs.
The assumption of alcoholic beverages when taking Tadalafil does not represent a danger unless done in excess, up to five servings of liquors, or five glasses of wine or beer does not constitute a threat. Exciding those limits might affect blood pressure to decrease. Tadalafil comes in the form of tablet and is taken orally, the recommended dosage to start with is the 10 mg, subjects suffering from a minor degree of impotence might switch to the lesser potent 5 mg, or for a more serious form of Erectile Dysfunction, is available a more powerful dosage of 20 mg.
During the trial studies, has been demonstrated that a 20-gr dosage of Tadalafil, has the equivalent inhibitory action on the enzyme PDE5 of a 100 mg tablet of “Viagraâ€. Tadalafil is a prescription Erectile Dysfunction medication, and can be taken once every 24 hours if needed. As for every medication of this class, the use of Tadalafil is not advised for subjects using medications containing Nitrates. Nitrates are commonly used in prescription medicines for the cure of Angina, and can cause cardiac problems if taken with smooth muscle relaxant such as Tadalafil.
