Asparaginase is an enzyme that is used as a medication and in food manufacturing.[1][2] As a medication, L-asparaginase is used to treat acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), and non-Hodgkin's lymphoma.[1] It is given by injection into a vein, muscle, or under the skin.[1] A pegylated version is also available.[3] In food manufacturing it is used to decrease acrylamide.[2]

Common side effects when used by injection include allergic reactions, pancreatitis, blood clotting problems, high blood sugar, kidney problems, and liver dysfunction.[1] Use in pregnancy may harm the baby.[4] As a food it is generally recognized as safe.[2] Asparaginase works by breaking down the amino acid known as asparagine without which the cancer cells cannot make protein.[1]

Asparaginase was approved for medical use in the United States in 1978.[3] It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[5] The wholesale cost in the developing world is about US$42.00 per 10,000 IU vial.[6] This amount in the United Kingdom costs the NHS 613.00 pounds.[7] It is often made from Escherichia coli or Erwinia chrysanthemi.[3][8]
