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.
Olsalazine is used to treat a certain type of bowel disease called ulcerative colitis. It does not cure ulcerative colitis, but it may decrease symptoms such as stomach pain, diarrhea, and rectal bleeding caused by irritation/swelling of the colon/rectum. After an attack is treated, olsalazine is used to increase the amount of time between attacks.
Olsalazine is a salicylate anti-inflammatory drug. It is believed to work by blocking the production of certain natural substances (e.g., prostaglandins) that may cause pain and swelling.
