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.

  • Product Details


    Lonsurf is a prescription cancer treatment medication that is used specifically for metastatic stomach, colon, or rectal cancer. It is commonly prescribed for patients who are unable to take other chemotherapy medications, and it is formulated differently with two medicines that work to stop cancer cells from being able to make copies of themselves and resulting in slowed tumor growth. Lonsurf is often part of gastric cancer treatment or colorectal cancer treatment, and you can buy Lonsurf online with a prescription at most pharmacies.
