DRUG CLASS AND MECHANISM:
- Interferon beta-1b is a protein produced by recombinant DNA technology using E. coli bacteria into which the human interferon beta genes have been introduced. It is used for treating multiple sclerosis (MS). Interferon beta has antiviral properties and plays a role in regulating the immune response. The exact mechanism by which interferon beta-1b works in the body to treat MS is not known. Interferon beta-1b does not cure MS. Rather, it helps to decrease the number of flare-ups and slows the occurrence of some of the physical disability that commonly occurs in the disease.
- Interferon beta-1b was approved by the FDA in July, 1993.
