| Rebif ® is a drug used in the treatment of multiple
sclerosis. It is from a class of drugs known as interferons Interferon
beta-1a is a recombinant DNA produced synthetic of naturally occurring
proteins.
Interferons are cytokines. Three major classes of interferon have
been identified - interferon alpha, interferon beta and interferon gamma.
Interferon alpha and beta form the Type I class of interferons and Interferon
gamma is a Type II interferon.
Interferons are species specific. The effects and results of interferon
therapy and animal experimentation is difficult to apply across the
human-animal species barriers since the effects they have within any
given species are different.
The specific interferon-induced proteins and mechanisms by which
interferon beta-1a exerts its effects in multiple sclerosis (MS) have
not been fully defined.
Rebif ® is administered by subcutaneous injection (injection
under the skin) three times weekly.
