Autor: Norman A. García, Susana Criado, Daniel O. Mártire, Cecilia Challier

Publikováno v: Journal of Photochemistry and Photobiology A: Chemistry. 332:399-405

The imidazoline-based ophthalmic drugs oxymetazoline and xylometazoline are widely used as ocular decongestants in pharmaceutical preparations. In this paper, the degradation of these drugs and the model compound 2-methyl-2-imidazoline, was studied i
