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.

    Gastrogard is a horse ulcer treatment medication that works by reducing the amount of acid present in the horse's stomach to maintain higher PH levels that allow ulcers to heal. It is used to treat horse gastric ulcers as well as preventing them for animals prone to getting them. Omeprazole is part of the proton pump inhibitor class of antacid medications, and it effectively reduces the horse's stomach acidity. Gastrogard is among the most common EGUS treatment medications for horses.

    You can buy Gastrogard with a veterinarian's prescription, and your best Gastrogard price on it will be when you order pet medication online from Canada Pharmacy.
