In vitro studies have shown that the effect of tadalafil is more potent on PDE5 than on other phosphodiesterases. These studies have shown that tadalafil is >10,000-fold more potent for PDE5 than for PDE1, PDE2, PDE4, and PDE7 enzymes, which are found in the heart, brain, blood vessels, liver, leukocytes, skeletal muscle, and other organs. Tadalafil is >10,000-fold more potent for PDE5 than for PDE3, an enzyme found in the heart and blood vessels. Additionally, tadalafil is 700-fold more potent for PDE5 than for PDE6, which is found in the retina and is responsible for phototransduction. Tadalafil is >9,000-fold more potent for PDE5 than for PDE8, PDE9, and PDE10. Tadalafil is 14-fold more potent for PDE5 than for PDE11A1 and 40-fold more potent for PDE5 than for PDE11A4, two of the four known forms of PDE11. PDE11 is an enzyme found in human prostate, testes, skeletal muscle and in other tissues (e.g., adrenal cortex). In vitro, tadalafil inhibits human recombinant PDE11A1 and, to a lesser degree, PDE11A4 activities at concentrations within the therapeutic range. The physiological role and clinical consequence of PDE11 inhibition in humans have not been defined.Curiosity always kills the cat.Your doctor may have prescribed it for another reason.

The Sprite was the big disappointment in this trial, and despite the number of people who swear by it, it seemed to actually have a detrimental effect on the flowers after a few days. By the end of the week, the flowers in the Sprite group were considerably droopier and looked positively pathetic. The Sprite seemed to somehow cause the flower stems to lose their integrity. The vodka and control groups ran about even, with the control group perhaps taking a slight edge. The vodka seemed to have the effect of causing the flowers to open more fully, making them look a bit more spent. Perhaps the amount of alcohol we added was too small to have a preservative effect, but the effect that it did have did not seem to be positive.

In a rat prenatal and postnatal development study, the no observed effect dose was 30 mg/kg/day. In the pregnant rat the AUC for calculated free drug at this dose was approximately 18-times the human AUC at a 20 mg dose.
