[Experimental studies on the influence of selected preparations on secretion of tear fluid. I. Schirmer test I and lysozyme test].

In the paper the influence of ambroxol, betanechol and mesna on the production of tear fluid by the lacrimal gland in rabbits was studied and compared with the effectiveness of bromhexine hydrochloride. Tear secretion was stimulated by the Schirmer I and lysozyme tests. The obtained results indicate that all four examined drugs stimulate the production of tear fluid. The greatest stimulation of secretion was observed after mesna and then after betanechol and ambroxol. The least potent drug was bromhexine.
