Peginterferon beta-1a injection is used to treat the relapsing forms of multiple sclerosis (MS). Peginterferon beta-1a will not cure MS, but it may slow some of the disabling effects and decrease the number of relapses of the disease. Peginterferons are natural substances that are produced in the body to help fight infections. Peginterferon beta-1a is a synthetic (man-made) version of these substances.

Perflutren is used to allow certain segments of the heart to be seen more clearly on an echocardiogram.
