PURPOSE: To evaluate the clinical effectiveness of bimatoprost (Lumigan®, Allergan, Inc.) when used as a replacement for latanoprost (Xalatan®, Pharmacia) in the treatment of glaucoma and ocular hypertension. METHODS: This was a community-based, two-month, open-label, multicenter, trial. Patients with glaucoma or ocular hypertension who needed additional IOP lowering or who were intolerant of other glaucoma medications were placed on bimatoprost therapy (alone or in combination with other drugs at the physician's discretion). RESULTS: This first report of the data from this study focuses on those patients for whom the physician chose to replace latanoprost therapy with bimatoprost therapy (n = 1283). After two months of bimatoprost therapy, the mean decrease in IOP was 3.4 mmHg, and many more patients had achieved low target pressures. The percentage of patients achieving a target pressure of ≤ 18 mmHg doubled from 33-66% (p < 0.001). The percentage of patients achieving target pressures of ≤ 15 and ≤ 14 mmHg was approximately three to four times greater at the end of the study than at the beginning; increasing from 11-36% and from 6-26%, respectively (p < 0.001). A subgroup analysis showed comparable improvements in IOP control regardless of the previous treatment regimen or whether bimatoprost was used alone or in combination with other medications. The most commonly reported adverse event was conjunctival hyperemia (3.7%; 47/1283). CONCLUSIONS: Bimatoprost therapy is well-tolerated and helps many more patients reach low target pressures when used as a replacement for latanoprost in a variety of treatment regimens.
