Immunomodulator Flashcards
Prednisone
MOA:
-↓ # of circulating lymphocytes
- Inhibit PMN migration and chemotaxis
- Inhibit phospholipase A2
Indications:
- Any immune mediated chronic disease
- Cerebral edema
- Surfactant production prior to delivery

Toxcitiy
- N/V/D
- neutropenia
- infections
- T and B cell suppression
Rho Immune Globulin (RhoGam)
human anti-Rh Ig
