Observational study results in glaucoma patients undergoing a regimen replacement to fixed combination travoprost 0.004%/timolol 0.5% in Germany.

With the launch of the fixed combination of travoprost 0.004%/timolol 0.5% (trav/tim) in Germany in May 2006, a noninterventional observational study designed as an open-label, multicenter, 6-week trial was initiated in order to evaluate the efficacy and tolerability of this new drug combination in glaucoma patients. Participants were grouped into categories according to previous drug regimens: those on timolol monotherapy; those on prostaglandin analog (PGA) monotherapy; those on concomitant therapy with a PGA and timolol; and those on fixed combinations. Trav/tim was well accepted by the patients, with 87.9% judging the tolerability of the therapy as good, very good, or excellent. Analysis of intraocular pressure (IOP) measurements showed statistically significant IOP decreases in all four categories examined in our study after regimen substitution with fixed-combination trav/tim. Fixed-combination prostaglandin analog/beta-blocker formulations are an attractive therapeutic option due to their strong IOP-lowering efficacy with once-daily dosing. In this study, glaucoma patients who underwent a regimen modification to fixed-combination trav/tim showed further reductions in IOP, irrespective of which selected monoor multiple therapies had been used previously.
