What is a Generic Drug?

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.

    Combigan (Brimonidine/Timolol)

    Combigan is a combination of 2 drugs used to treat high-pressure symptoms of the eye, namely glaucoma (open-angle type) and some other eye diseases like ocular hypertension. Lowering the pressure in the eye helps prevent blindness in these conditions. Combigan eye drops are used when single-ingredient drugs are unable to treat glaucoma.

    The 2 drugs in Cambigan are brimonidine and timolol. Brimonidine is an alpha agonist. It acts by decreasing the amount of fluid formed in the eye along with improving the fluid drainage from within the eye. Timolol belongs to the group of beta blockers. It decreases the amount of fluid formed within the eye. The effect of both drugs results in lowering the intra ocular pressure and giving relief to the patient.

    Combigan eye drops are not recommended for children under 2 years of age due to increased risk of side effects.

    You can buy Combigan eye drops for glaucoma treatment from Canada Pharmacy and have it delivered to you.
