[Combination therapy in the medical treatment of glaucoma].

Abstract

A combination of antiglaucoma medications is indicated if monotherapy is not sufficient to achieve the predefined target pressure and/or in case of a progression of glaucomatous damage or conversion from ocular hypertension to glaucomatous optic neuropathy. Most recently many fixed combinations with two active compounds have become available for the medical treatment of glaucoma. Compared to non-fixed combinations, these drugs offer a much easier use for the patients. Fixed combinations have to be applied less frequently which may improve adherence. Furthermore, they most likely contain a lower amount of toxic preservatives compared to non-fixed combinations. And finally, fixed combinations may eliminate the risk of a "washout" of the first medication by using the second product of a non-fixed combination too soon after the first drop has been installed. This review aims to examine the most important aspects of IOP-lowering fixed and non-fixed combinations in glaucoma management with a clear focus on the results obtained with fixed combinations. In Germany, fixed combinations with the compositions dorzolamide/timolol (FCDT), brinzolamide/timolol (FCBRINT), latanoprost/timolol (FCLT), travoprost/timolol (FCTT), bimatoprost/timolol (FCBIMT), brimonidine/timolol (FCBT), pilocarpine/timolol (FCPT) and metipranolol/timolol (FCMT) are approved for the medical management of glaucoma and ocular hypertension. The results of clinical studies comparing fixed combinations with their active ingredients and with the corresponding non-fixed combinations will be discussed. Furthermore - if available - the results of direct comparisons of the efficacy and safety of different IOP-lowering fixed combinations are summarised.
