The efficacy and safety of unfixed and fixed combinations of latanoprost and other antiglaucoma medications.
Adjunctive therapy for the management of glaucoma is commonly used. Unfixed combinations of the prostaglandin analog latanoprost and other glaucoma medications have been demonstrated to effectively lower intraocular pressure (IOP). The range of reported additional reductions in IOP compared to a monotherapy baseline are as follows: latanoprost-timolol (13-37%), latanoprost-pilocarpine 2% (7-14%), latanoprost and carbonic anhydrase inhibitors (15-24.1%), and latanoprost and dipivefrin (15-28%). There is a fixed combination of latanoprost (0.005%) and timolol (0.5%) that has been investigated in Phase III trials in Europe and the United States. In these trials, it was noted that the efficacy of the fixed combination was superior to either of the monotherapy components. After 12 months of follow-up of patients on fixed combination, there was no evidence of long-term drift. The new formulation appears to be safe and does not demonstrate any more side effects than either of the components. The convenience of a fixed combination may enhance patient compliance. Unfixed combination therapy with latanoprost and other antiglaucoma medications and the fixed combination formulation of latanoprost and timolol provide an effective and safe option for lowering IOP in glaucoma patients.
