Preservative-free Tafluprost/Timolol Fixed Combination: Morning vs Evening Dosing

The ideal dosing for preservative-free tafluprost/timolol fixed combination remains to be elucidated. The present study compared the 24-hour intraocular pressure efficacy obtained with tafluprost/timolol given once in the evening with placebo once in the morning, versus that with the same fixed combination administered once in the morning with placebo given once in the evening in consecutive patients with open-angle glaucoma insufficiently controlled with branded, or generic latanoprost monotherapy.
