In Vitro Study of Inflammatory Potential and Toxicity Profile of Latanoprost, Travoprost, and Bimatoprost in Conjunctiva-Derived Epithelial Cells

Abstract

The comparison of latanoprost, travoprost, and bimatoprost, in their commercial formulations, showed that none of them appeared to induce direct stimulation of the inflammatory pathways involving adhesion molecules or class II antigens, although these markers have been found ex vivo in conjunctival specimens from patients treated with prostaglandins. In fact, their toxicity was mild and seemed to be primarily related to the concentration of BAC, their common preservative, which may be the major factor responsible for long-term ocular surface reactions in patients receiving topical prostaglandins, but most likely is not a factor in early and transient conjunctival hyperemia.
