Pharmocology Flashcards
(32 cards)
What is cyclosporine’s toxicity?
Renal toxicity, hirsutism, gingival hyperplasia
What is cyclosporine?
Calcineurin inhibitor. For immunosuppression
How do corticosteroids work?
Bind to glucocorticoid receptor. Inhibition of HAT, directly or by his tone deacetylase-2 (HDAC2). Preventing transcription. Also an indirect inhibitor of GATA-3
What is sirolimus?
mTOR. Inhibitor. Binds FKBP12 preventing cell cycle-driven clonal expansion. Immunosuppression
What does mycophenolate do?
Inhibits inosine phosphate, inhibiting DNA synthesis. Immunosuppression through cell cycle inhibition
How does Azathioprine work
Immunosuppression cell cycle inhibitor. Extensive metabolic conversion. Incorporation of fraudulent nucleotide in DNA. And blockage of co stimulation of T cells
Which immunosuppressants are contraindicated in pregnancy?
Cell cycle inhibitors: methotrexate, cyclophosphamide, Azathioprine, mycophenolate mofetil
Induction of suppression best by?
Basiliximab or T cell depletion by thyroglobulin
Immunosuppressants increase risk across the board for?
Infection and tumors
Adalimumab
TNF-Alpha inhibitor, soluble cytokine receptor
Certolizumab
TNF-Alpha inhibitor, soluble cytokine receptor
Etanercept
TNF-Alpha inhibitor
Golimumab
TNF-Alpha inhibitor
Infliximab
TNF-Alpha inhibitor
Omalizumab
IgE antibody
Roflumilast
PDE4 inhibitor
Zileuton
Leukotriene synthesis inhibitor
Montelukast
Leukotriene receptor blockers
Amphotericin B
Antifungal that punches holes in cell membranes. Renal toxicity. Given IV. Could cause anemia, abnormal liver function and seizures. Poor solubility
Flucytosine
Antifungal. Prevents cell replication by nucleic acid inhibition 5-FU. Conversion by intestinal micro flora.
Caspofungin
Anti fungal. Echocandins. Inhibitor of beta-1-3 glucan. Used against aspergillosis and candida infections
Griseofulvin
Anti fungal. Works through inhibition of the mitotic spindle. CYP3A4 inducer.
Terbinafine
Antifungal. Block synthesis of ergosterol. Blocks squalene to squalene epoxide. Some lymphopenia and neutropenia
Azole group
Antifungal. Blocks ergosterol synthesis. Prevent conversion of lanosterol to ergosterol. Inhibition of p450
