A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Cosopt PF is a preservative-free eye solution used to reduce pressure in the eye for people with open-angle glaucoma or ocular hypertension. It combines two active ingredients, Dorzolamide and Timolol, which work together to decrease the production of fluid in the eye, thereby lowering intraocular pressure.
Before you buy Cosopt PF, consult with a healthcare provider to understand the proper usage, potential side effects, and whether it's the most appropriate treatment for your specific condition. To get the best Cosopt PF cost, you can buy them from a Canada or a Canadian Pharmacy.
Open-Angle Glaucoma is a common type of glaucoma where eye drainage canals clog over time, leading to pressure increase and possible vision loss due to optic nerve damage. Ocular Hypertension is a condition with higher-than-normal eye pressure but without signs of glaucoma. This could heighten the likelihood of developing glaucoma.
