Week 3 Immunity Drugs Flashcards
Immune stimulants do what?
energize and assist immune system to fight specific pathogens or cancer cells
Immune suppressants do what?
Block and drepress immune system to prevent transplant rejection or severe tissue damage or autoimmune disease
Immune suppressant classes
- T/B cell suppressors
- Monoclonal antibodies
Immunes suppressant prototypes
Cyclosporine and bevacizumab
Immune stimulant classes
- interferon
- colony-stimulating factors
Immune stimulant prototypes
- interferon alpha 2b
- fligrastim
Interferon prototype drug
Interferon alpha 2b
Colony stimulating factor prototype drug
fligrastin
T/B cell suppressants prototype drug
cyclosporin
Monoclonal antibodies prototype drug
Bevacizumab
Therapeutic action of Interferons
- Inhibits the growth of the tumor cells and enhances immune response
- inhibits tumor growth and replication
- enhances inflammatory reaction
Therapeutic action of colony-stimulating factor
- increase production of neutrophils in bone marrow
- increase WBC production
Therapeutic action of T/ B cell suppressants
- block antibody production by B cells
- inhibit suppressor and helper T cells
- reversibly inhibits immunocompetent lymphocytes, t helper cells, suppressor cells, and lymphokine production
Therapeutic action of Monoclonal antibodies
- inhibits vascular endothelial growth factor leading to decreased angiogenesis and cell proliferation
- work against malignant or viral cell sites
- specific key to specific receptor types
Indication for Monoclonal antibodies
- metastic colorectal cancer, non-squamous cell, non small cell lung cancer, glioblastoma, renal cell carcinoma, cervical cancer, ovarian cancer, COVID 19
Indication for T/B cell suppressant
- prophylaxis for solid organ rejection
- treatment for chronic rejection
- treatment for RA and psoriasis
Indication for colony-stimulating factor
- reduce infections in pts w/ bone marrow suppression
- neutrophil recovery w/ myelosuppressive chemotherapy, leukemia, bone marrow transplants
Indication for Interferons
- hairy cell leukemia, chronic hep B/C, malignant melanomia,
Pharmacokinetics for interferons
- IM, IV, SubQ
- rapid onset, peak 3-8hr
- broken down in kidney
Pharmacokinetics for Colony- stimulating factor
- IV, SubQ
- Varying peak, onset and duration
- metabolism and excreted unknown
Pharmacokinetics for T/B cell suppressants
- varies by med; GI or IV
- metabolized by liver and excreted by stool or urine
Pharmacokinetics for monoclonal antibodies
- given IM, IV, SubQ
- GI rapidly breaks down protein
- processed like naturally occurring antibodies
Adverse Effects in Monoclonal Antibodies
- thrombotic events, GI perforation
- third spacing of fluids and shock!
- flu-like symptoms
Adverse Effects of T/B cell suppressants
-increased risk of infection
- increased risk of development of neoplasms
- possible pulmonary edema
