Comparative cost evaluation of brand name and generic ophthalmology medications in Ontario.
Abstract |
Medication cost for the same indication can vary considerably and can affect patient compliance. In this comparative cost analysis of commonly prescribed ophthalmology medications, the differences in cost between generic and brand name medications as well as different medications within an individual drug class were evaluated. Eye preparations from the Ontario Drug Benefit Formulary were identified, and further agents commonly prescribed by ophthalmologists were included. The standardized prescription drug cost, which includes the cost of the medication, mark-up, and dispensing cost, was provided by Ontario Shoppers Drug Mart stores in July 2016 for 103 common medications using typical dosages and durations. Based on medication class, the highest and lowest cost medications were antiallergy agents ( Zaditor [ ketotifen], Vasocon [ naphazoline]), antibiotic ophthalmic solutions (Vigamox [ moxifloxacin], generic ciprofloxacin), oral antibiotics ( Cipro [ ciprofloxacin], generic cephalexin), antibiotic ophthalmic ointments (generic erythromycin, Tobrex [ tobramycin]), antiviral treatment ( Valtrex [oral valacyclovir], Viroptic [topical trifluridine]), blepharitis treatment ( Zithromax [oral azithromycin], generic oral tetracycline), beta- adrenergic inhibitors ( Timoptic [topical timolol], generic topical timolol), topical prostaglandin analogues ( Xalatan [ latanoprost], generic travoprost), oral carbonic anhydrase inhibitors ( methazolamide, acetazolamide), topical carbonic anhydrase solutions ( Trusopt preservative-free [ dorzolamide], Azopt [ brinzolamide]), topical alpha-adrenergic agonists ( Alphagan [ brimonidine], generic brimonidine), topical muscarinic agonists (Isopto carpine [ pilocarpine], Diocarpine [ pilocarpine]), topical combination glaucoma agents ( Cosopt [ dorzolamide- timolol], generic dorzolamide- timolol), topical lubricants ( Lacri-lube, Isopto tears), topical nonsteroidal anti-inflammatory drugs (Acuvail [ ketorolac], Ilevro [ nepafenac]), and steroids (Durezol [ difluprednate], Pred mild [ prednisolone]). Substantial cost differences exist between ophthalmology medications of the same class. We encourage ophthalmologists to be aware of the associated costs of the medications they prescribe and to use this information in their decision making.
