Abstract Objective:To provide an interim report of the safety and efficacy of a fixed combination ophthalmic solution containing 2% of carteolol hydrochloride and 0.005% of latanoprost(Mikeluna®, hereinafter referred to as“this drug”)in the long-term use under actual use conditions.

Subjects and methods:This specified drug use survey was conducted in patients with glaucoma and ocular hypertension to whom this drug was administered for the first time at 80 facilities nationwide from April 1, 2017. Data were collected from 325 patients until September 27, 2019, and 295 cases were included in the safety analysis and 275 cases in the efficacy analysis. In the safety analysis, adverse drug reactions and patient background factors were evaluated. In the efficacy analysis, the time course of the mean intraocular pressure(IOP), the time course of the mean IOP in subgroup analysis based on IOP before administration(defined as baseline)and diagnosis, the adjusted mean IOP reduction from baseline, the number and percentage of eyes that achieved the target of IOP reduction from baseline, and the time course of mean IOP based on the reason for using this drug were evaluated.

Results:In the safety analysis, 34 adverse drug reactions were reported, including corneal disorders(8 cases), abnormalities in visual field tests(4 cases), blepharitis(3 cases), and visual field defects, blurred vision, and conjunctival hyperemia(2 cases each). Three of 4 cases with visual field abnormalities and all cases with visual field defects were also attributed to exacerbation of the underlying diseases. In the efficacy analysis, the IOP reduction from baseline at 12 months after starting administration was 1.9±2.9 mmHg(mean±standard deviation).

Conclusion:In terms of safety, there were no serious unexpected adverse drug reactions and new concerns and it was not necessary to revise precautions in the package insert. As for efficacy, the mean IOP was lower than baseline during the 12 months after starting administration.
