What is Betaseron (Interferon beta-1b)?

Betaseron is the trade name of a prescription drug containing interferon beta-1b as the active ingredient. It is used in the treatment of multiple sclerosis (MS) in patients who have experienced their first episode of clinical exacerbation and show signs that indicate they have multiple sclerosis. It slows the progression of multiple sclerosis; hence, reducing the frequency of clinical exacerbation. Interferon beta-1b belongs to a class of interferons called cytokines. It should be noted that Betaseron does not cure multiple sclerosis; however, it slows down its progression and reduces the frequency of relapsing. It is manufactured by Bayer pharmaceutics.

Active ingredients

Interferon beta-1b is the active component of Betaseron, a protein molecule containing anti-inflammatory effects. The actual mechanism on how it works is unknown, but it is believed to works by reducing the number of inflammatory cells that cross the blood brain barrier and stimulates secretion of nerve growth factor which promotes the growth nerve cells. 

Conditions treated

It is used in the management/prevention of relapsing of multiple sclerosis in patients who have experienced clinical exacerbation or have an MRI indicating the presence of multiple sclerosis.
