Background: Present study was undertaken to analyse and compare the efficacy and safety of 1%Brinzolamide
and 0.5% Timolol fixed-dose combination with its free equivalent combination in glaucoma patients at Tertiary
Care Hospital.
Method: It was a Prospective, Observational study. Patient were randomised into two group. Group-I
patients received 1%Brinzolamide/0.5%Timolol fixed-dose combination and group-II patients received free
equivalent combination of 1%Brinzolamide +0.5% Timolol. Patients were assessed for general and ocular
examination on the day of enrolment and followed-up on 2, 4, 6, 8, and 12 weeks. For safety assessment
adverse event related to drug were asked at each follow-up. Descriptive statistics were used to describe the
variables mean±SD (standard deviation).p<0.05 was considered significant.
Result: Significant reduction (p<0.001) in IOP from baseline 25.75±3.14mmHg to 17.6±1.58mmHg and from
baseline 25.47±3.05 to 17.9±1.08mmHg at 12th week visit was observed with 1%Brinzolamide/0.5%TimololFDC and free equivalent combination of 1%Brinzolamide+0.5%Timolol respectively. On comparison between
the groups, the mean reduction was not statistically significant (p>0.05). 8(40%) patients in
1%Brinzolamide/0.5%Timolol-FDC group and 13(65%) patients in 1%Brinzolamide+0.5%Timolol group
reported ocular discomfort (Ocular Burning, Stinging, Ocular irritation, Ocular itching)
Conclusions: Both fixed and free equivalent combination of 1%brinzolamide and 0.5% timolol are equivalent
in reducing the intraocular pressure in glaucoma patients with lesser incidence of adverse events seen with
1%brinzolamide/0.5%timolol-FDC.FDCof 1%Brinzolamde/0.5%Timolol can be a better alternative to its free equivalent combination of 1%Brinzolamide+0.5% Timolol.
