Efficacy and tolerability of benzalkonium chloride-free travoprost in glaucoma patients switched from benzalkonium chloride-preserved latanoprost or bimatoprost

摘要

IntroductionThe preservative benzalkonium chloride (BAK) is used to preserve several topical, intraocular pressure (IOP)-lowering glaucoma medications but can cause tolerability concerns that may lead to decreased adherence to treatment and ultimately diminish the effectiveness of IOP control. The study aimed to determine the efficacy and tolerability of BAK-free travoprost preserved with polyquaternium-1 in glaucoma patients switched from BAK-preserved latanoprost or bimatoprost.
