Adjuvant

Referring to a management strategy used in addition to the primary therapy.
Immunology A substance that enhances or diversifies the immune response; a nonspecific immune enhancer—e.g., Freund’s adjuvant, BCG vaccine—consisting of particulate-rich oily substances which promotes protein aggregation; adjuvant mixed with an antigen acts as a tissue depot, slowly releasing antigen and activating the immune system.
Pharmacology A drug that modulates the actions of other drugs which, when added to a medication, enhances its pharmacologic effect. See Interference.
