Pharmacodynamics of Tafluprost 0.0015% Eye Drops: a Comparison Between the Preserved and Unpreserved Formulation
Pharmacodynamics of Tafluprost 0.0015% Eye Drops: a Comparison Between the Preserved and Unpreserved Formulation in Patients With Open-angle Glaucoma or Ocular Hypertension
The objective of this study is to investigate the pharmacodynamics (as expressed in intraocular pressure [IOP]) of two formulations of tafluprost 0.0015% eyedrops (preserved and unpreserved) in patients with open-angle glaucoma or ocular hypertension.
The primary aim of this study is to show that IOP reduction between the two formulations is equivalent at the end of the 4 week treatment period.

Overall and Time-wise Comparisons of IOP at Week 1

The overall and time-wise, i.e. at 8:00, 12:00, 16:00 and 20:00, comparisons of IOP at week 1 (diurnal IOP and IOP value at given timepoint at 1 week minus corresponding value at baseline: unpreserved-preserved) were done using the RM ANCOVA model.
