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.

Description

Tegretol XR (extended release) is an epilepsy treatment medication used to prevent seizures and to reduce the severity of ones that do occur. Carbamazepine is an anticonvulsant drug and works by limiting the spread of signal in the brain that overwhelm the neural network and cause seizure activity, and it also makes nerve activity in the brain occur more normally. In rarer instances Tegretol may be used as a nerve pain relief medication. You can buy Tegretol XR with a prescription here at Canpharm.
