Effects of topical administration of tafluprost and combination of tafluprost and timolol or tafluprost and betaxolol on Schirmer tear test, intraocular pressure, and pupil size in clinically healthy dogs.

Tafluprost alone or in combination with timolol and betaxolol was able to reduce intraocular pressure. The greatest effect of the drugs occurred 6 and 8 h PI. The present study revealed that the combination of tafluprost/betaxolol is more potent in decreasing IOP than tafluprost alone or a combination of tafluprost/timolol in healthy dogs.
