Beta-interferon (Betaseron) is a bioengineered (E coli produced )
human protein given as an injection every other day to MS patients.
In a controlled trial using relapsing remitting MS patients it
demonstrated a statistically significant reduction of the frequency
and severity of exacerbations. This amounted to about a 30% reduction
in frequency. A controlled study of chronic progressive MS patients
has not been performed. A controlled study of new MS patients has
also not been performed. You can obtain information about the drug
from Berlex Pharmaceutical Company.
