Tadalafil relaxes muscles of the blood vessels and increases blood flow to particular areas of the body. Tadalafil under the name of Cialis is used to treat erectile dysfunction (impotence) and symptoms of benign prostatic hypertrophy (enlarged prostate). Another brand of tadalafil is Adcirca, which is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women. Do not take tadalafil if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, and some recreational drugs such as "poppers". Taking tadalafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure. Some medicines can cause unwanted or dangerous effects when used with tadalafil. Tell your doctor about all your current medicines, especially riociguat (Adempas). Tadalafil is a potent and selective inhibitor of PDE5A (Phosphodiesterase-5, PDE5). This compound prevents the breakdown of phosphodiesterases, many of which are used as secondary messengers. (Pub Med 25861307) used Tadalafil, a PDE5 inhibitor, to study its possible endothelial cyto-protective and thrombo-resistance effects in male rabbit models. By preventing the breakdown of these messenger molecules, tadalafil can prolong signal transduction and amplify its effect.

Tadalafil is an orally administered drug used to treat male erectile dysfunction impotence. water solubility, Practically insoluble in water, Not Available. INTRODUCTION. Tadalafil（TDL）is a poorly water soluble drug which was approved recently for the management and treatment of male erectile. Tadalafil is an orally administered drug used to treat male erectile dysfunction (impotence). It is marketed worldwide under the brand name Cialis. Tadalafil's distinguishing pharmacologic feature is its longer half-life (17.5 hours) compared with Viagra and Levitra (4-5 hours). This longer half-life results in a longer duration of action and is, in part, responsible for the Cialis nickname of the "weekend pill." This longer half-life also is the basis of current investigation for tadalafil's use in pulmonary arterial hypertension as a once-daily therapy. Tadalafil is a PDE-5 inhibitor with IC50 of 1.8 n M in a cell-free assay. Tadalafil is at least 9000 times more selective for PDE5 than most of the other families of PDEs, with the exception of PDE11. It can partial inhibits PDE11 Tadalafil is a PDE-5 inhibitor with IC50 of 1.8 n M in a cell-free assay. Tadalafil is at least 9000 times more selective for PDE5 than most of the other families of PDEs, with the exception of PDE11. It can partial inhibits PDE11 Tadalafil (2 mg/kg or 10 mg/kg) significantly improves neurological functional recovery and increases cerebral vascular density and the percentage of Brd U-positive endothelial cells around the ischemic boundary. Tadalafil selectively increases c GMP but not c AMP in brain of rats.
