[Efficacy and tolerability of 2 presentations of eyedrops combining carteolol 2% and pilocarpine 2% in primary open-angle glaucoma and simple ocular hypertension]. / Efficacité et tolérance de 2 présentations de collyre associant le cartéolol 2% et la pilocarpine 2% dans le glaucome primitif à angle ouvert et l'hypertension oculaire simple.

PURPOSE: The aim of the study was to compare 2 combinations of eye drops containing 2% carteolol and 2% pilocarpine: LCM 1010: ready to use eye drops CBS 341A: eye drops to be reconstituted (freeze-dried powder + solvent). METHODS: Ninety-seven patients with primary open angle glaucoma or simple ocular hypertension were included in a randomized, double-blind multicentric study comparing 2 parallel groups of treatment. Intra-ocular pressure was greater than 21 mmHg with beta-blocker alone. One instillation of 2% carteolol-2% pilocarpine combination was given twice a day for one month. Before and after this treatment, intra-ocular pressure was measured at 9 am (12 hours after evening instillation) and at 11 am (2 hours after morning instillation). RESULTS: Both treatments reduced intra-ocular pressure by a comparable amount and there was no significant difference between groups at either measure: at 9 am: 2.11 +/- 2.39 mmHg (mean +/- SD) for LCM 1010 1.79 +/- 1.73 mmHg for CBS 341 A p = 0.25 at 11 am: 3.75 +/- 3.83 mmHg for LCM 1010 3.40 +/- 1.69 mmHg for CBS 341 A p = 0.42. Both eye drops were generally well tolerated. CONCLUSION: Efficacy and safety of ready to use eye drops 2% carteolol-2% pilocarpine combination proved to be comparable to that of eye drops to be reconstituted in the treatment of ocular hypertension poorly controlled by beta-blocker eye drops alone.
