Pharmacology of Corticosteroids and Anti-allergic Agents

This advanced module is designed for diploma and degree students in pharmacology, immunology, and clinical medicine in Zambia. It explores two powerful classes of immunomodulators. First, it covers corticosteroids (e.g., prednisolone, dexamethasone), detailing their broad anti-inflammatory and immunosuppressive mechanisms via phospholipase A2 inhibition and cytokine suppression, along with their extensive clinical uses and serious long-term adverse effects. Second, it examines anti-allergic agents, including histamine pharmacology, generations of H1-receptor antagonists (from sedating diphenhydramine to non-sedating loratadine), mast cell stabilizers (cromolyn), and antileukotriene drugs (montelukast). For Zambian healthcare students, mastering these drugs is crucial for managing a wide range of conditions from asthma and severe allergies to autoimmune diseases and inflammatory disorders, which are prevalent in patient populations and require careful therapeutic navigation.
