التداخل بين ليفوسيتريزين وبنتوكسيفيلين

There was a small decrease (~16%) in the clearance of cetirizine caused by a 400 mg dose of theophylline.

It is possible that higher theophylline doses could have a greater effect.

Antipyrine, Azithromycin, Cimetidine, Erythromycin, Ketoconazole, Theophylline, and Pseudoephedrine Pharmacokinetic interaction studies performed with racemic cetirizine demonstrated that cetirizine did not interact with antipyrine, pseudoephedrine, erythromycin, azithromycin, ketoconazole, and cimetidine.
