Efficacy and safety of bimatoprost/timolol fixed combination in the treatment of glaucoma or ocular hypertension.

When a single medication does not adequately control intraocular pressure, additional intraocular hypotensive agents are often added to the therapeutic regime. However, regimen complexity has been associated with reduced patient compliance. Treatment with a fixed combination may, therefore, increase compliance as a result of simplifying the dosage regimen. Bimatoprost/timolol fixed combination (BTFC) combines two clinically effective agents that decrease elevated intraocular pressure by independent mechanisms. In two clinical studies, BTFC was more effective than its individual components. Furthermore, in a non-inferiority study BTFC has been shown to be as effective as the association of its individual components. BTFC was clinically effective and generally well tolerated, with no unexpected adverse reactions reported for the BTFC compared with those reported for bimatoprost or timolol monotherapies.
