Effect of other drugs on Buy Cialis Tadalafil

Tadalafil 10mg Dosage is mainly metabolized with the participation of the CYP3A4 isoenzyme. Selective inhibitor of CYP3A4, ketoconazole (400 mg/day) increases the AUC of Tadalafil Usa in a single dose by 312% and SMACNA 22%, and ketoconazole (200 mg/day) increases the AUC of Tadalafil 10mg Dosage in a single dose by 107% and Smachna 15% relative to the AUC values for Tadalafil Citrate Dosage Smartelco one. Ritonavir (200 mg 2 times a day), an inhibitor of isoenzymes CYP3A4, 2C9, 2C19 and 2D6, increases the AUC of Tadalafil 40 Mg Dosage in a single dose by 124% without changing Cmax. Although no specific interactions have been studied, it can be assumed that other HIV protease inhibitors such as saquinavir and CYP3A4 isoenzyme inhibitors such as erythromycin and Itraconazole increase Tadalafil Citrate Dosage activity.

Selective inducer of CYP3A4, rifampin (600 mg/day), reduces the exposure of a single dose of Cialis Tadalafil Buy Online (AUC) by 88% and SMACNA 46% relative to the AUC values for Tadalafil Cialis From India Smartelco one. It can be assumed that the simultaneous use of other inducers of CYP3A4 isoenzyme should also reduce the concentration of Buy Tadalafil Canada in plasma.

Simultaneous administration of antacid (magnesium hydroxide/aluminum hydroxide) and Tadalafil For Erectile Dysfunction reduces the rate of absorption of Tadalafil Usa without changing the area under the pharmacokinetic curve for Cialis Tadalafil Tablets.
