Interaction with other drugs

Although specific interactions have not been studied, it can be assumed that protease inhibitors such as ritonavir and saquinavir, as well as CYP3A4 inhibitors such as erythromycin and Itraconazole, increase the activity of Tadalafil Eli Lilly. The simultaneous administration of antacid (magnesium hydroxide/aluminium hydroxide) and Tadalafil 5mg India reduced the rate of absorption of the latter without changing the AUC. Cheap Generic Tadalafil enhances the hypotensive effect of nitrates. This is due to the additive effect of nitrates and Tadalafil Tablets India on the metabolism of nitric oxide and cGMP.
