Abstract

Objective: To study drug use pattern in patients of primary open angle glaucoma (POAG) and to analyze the cost of different anti-glaucoma medications.

Materials and methods: This prospective study was carried in the glaucoma clinic of a tertiary care teaching hospital over a period of 9 months. The data collected for patients with POAG included the patient's demographic details and the drugs prescribed. Data were analyzed for drug use pattern and cost drugs used.

Results: In a total 180 prescriptions (297 drugs) analyzed, most drugs (83.83%) were prescribed by topical route as eye drops. β blockers (93.88%) were found to be the most frequently prescribed for POAG. Timolol (82.22%) was the most frequently prescribed drug and timolol with acetazolamide (17.22%) was the most commonly prescribed drug combination. Fixed dose combinations constituted 26.66% of prescriptions. β blockers were found to be cheaper than other anti-glaucoma drugs while prostaglandins analogs were the costliest. Instructions about the route, frequency and duration of treatment were present in all prescriptions. However, instructions regarding instillation of eye drops were missing in all prescriptions.

Keywords: cost analysis; drug use study; primary open angle glaucoma; β-blockers.
