Abstract:

PURPOSE: To evaluate the intraocular pressure (IOP) lowering efficacy of Garcinia kola 0.5% aqueous solution eye drops in patients with newly diagnosed primary open-angle glaucoma or ocular hypertension (POAG/OH).

MATERIALS AND METHODS: A randomized, double-masked, multicenter, active-controlled prospective study. Patients who met the inclusion criteria were randomly assigned in equal numbers to receive Timolol 0.5% eye drops as a control medication (A = Group 1 eyes) or Garcinia kola 0.5% eye drops as the study medication (B = Group 2 eyes). All drops were instilled at 6 am and 6 pm daily. Goldman applanation tonometry was performed at 9 am, 12 pm and 3 pm at baseline, week-6, week-12 and week-24 visits. Voluntary and actively elicited reports of adverse events were documented. The mean change in IOP over 24 weeks was the primary outcome measure. Both groups were compared for statistically significant differences at all visits. A P<0.05 was considered statistically significant.

RESULTS: A total of 178 patients were randomly assigned to G. kola and Timolol groups. At baseline there were no differences in mean IOP between groups, based on age, sex, or diagnosis. At the end of the study period (24(th) week), the mean (+/- SD) reduction in IOP was 12.93 +/- 2.3 mmHg (47.8% +/- 0.8% reduction) in G. Kola group and 13.09 +/- 2.8 mm Hg (48.2% +/- 1.03% reduction) in the Timolol group (P>0.05). Adverse events were mild in nature with no statistically significant differences between groups (P>0.05).

CONCLUSIONS: Garcinia kola ophthalmic solution significantly reduces IOP as compared to baseline. The IOP lowering effect of both treatments was equivalent.
