| In Vitro | In vitro activity: Tadalafil binds to PDE5 with KD of 2.4 nM. cGMP stimulates the binding of [3H]Tadalafil. Tadalafil (1 mM) results increased CYP3A protein expression in human hepatocytes Kinase Assay: Biochemical potencies (affinities) of these compounds for PDE5 determined by IC(50), K(D) (isotherm), K(D) (dissociation rate), and K(D) ((1/2) EC(50)), respectively, were the following: sildenafil (3.7 +/- 1.4, 4.8 +/- 0.80, 3.7 +/- 0.29, and 11.7 +/- 0.70 nM), tadalafil (1.8 +/- 0.40, 2.4 +/- 0.60, 1.9 +/- 0.37, and 2.7 +/- 0.25 nM); and vardenafil (0.091 +/- 0.031, 0.38 +/- 0.07, 0.27 +/- 0.01, and 0.42 +/- 0.10 nM). Thus, absolute potency values were similar for each inhibitor, and relative potencies were vardenafil>> tadalafil> sildenafil. 0.5 ml tadalafil solutions with different concentrations were added (0.2, 0.1, 0.05 and 0.025 μg ml-1, respectively) into semen samples. In both groups, samples treated with 0.2 μg ml-1 tadalafil had significant increase in sperm motility after 2 h incubation. |

| In Vivo | Tadalafil (2 mg/kg) almost completely restores penile oxygenation and abolishes neurotomy induced increase and substantially rescues muscle/fiber ratio in penile sectionsin sham-operated rats. Tadalafil (2 mg/kg or 10 mg/kg) significantly improves neurological functional recovery and increases cerebral vascular density and the percentage of BrdU-positive endothelial cells around the ischemic boundary. Tadalafil selectively increases cGMP but not cAMP in brain of rats. Tadalafil decreases the number of apoptotic cells and increases the phosphorylation of the 2 survival associated kinases Akt and extracellular signal-regulated kinase 1/2 in mice |
