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.

    Zarontin 250 mg

    Zarontin (Ethosuximide)

    Zarontin is used in the treatment of a specific type of seizure. This particular seizure is known as absence or petit mal seizure. Zarontin basically functions by keeping in check the electrical impulses of the brain which are present and at work during a seizure. Also, the electrical waves that define the brain activity during a seizure are not normal; thus, this medicine plays a key role in controlling these impulses when an individual is experiencing a seizure.

    Moreover, you have a choice of taking Zarontin on its own or in combination with other medicines. However, it is better that your doctor recommends the way you take this medicine. Zarontin 250 mg is available online at Canada Pharmacy at reasonable rates. You can also purchase ethosuximide 250 mg here.
