Biologic Response-Modifying and Antirheumatic Drugs Flashcards
Aldesleukin (IL-2)
Functional Classification
Antineoplastic-miscellaneous
Aldesleukin (IL-2)
Mechanism of Action
Enhancement of lymphocyte mitogenesis and stimulation of IL-2-dependent cell lines; enhancement of lymphocyte cytotoxicity; induction of killer cell activity; induction of inteferon-gamma production; results in activation of cellular immunity, production of cytokines, and inhibition of tumor growth

Interferon alfa-2b
Functional Classification
Antineoplastic-miscellaneous
Interferon alfa-2b
Chemical Classification
Protein product
Interferon alfa-2b
Mechanism of Action
Antiviral action inhibits viral replication by reprogramming virus; antitumor action suppresses cell proliferation; immunomodulating action phagocytizes target cells; may also inhibit virus replication in virus-infested cells
