Biological and biosimilar medicines

Biological medicines, or biologics, are a newer type of treatment for some long-term medical conditions, including rheumatoid arthritis and psoriasis.

They're made from proteins and other substances produced by the body.

Biosimilar medicines are biological medicines that are very similar to another already approved biological medicine.

They're not generics because the two medicines aren't identical. But biosimilars will have been approved and licensed in the same way as biologics.

Biosimilar medicines have the potential to save considerable money for the NHS and are an innovative new treatment option for patients.
