Lecture 15 Part II - Anti-inflammatory drugs Flashcards
Physiological effects of glucocorticoids?
regulation of carb, protein and fat metabolism, fluid balance, preservation of systems & homeostasis
Pharmacokinetics of GCs?
incr. lung deposition and pulmonary retention, high receptor binding-affinity, rapid clearance
Drug mechanism?
intracellular receptor, binds HDAC, alters gene expression, decreasing inflammatory gene transcription
GC principle effects?
suppress immune cells, inhibit synthesis, release and expression of cytokines, chemokines, adhesion molecules and lipid midiators involved in inflammatory response, also upregulates b-adrenergic receptors on smooth muscle
Oral GC?
Prednisone
Cushing syndrome?
hypercortisolism casuing buffalo lump and moon face; obese centre w thin legs and arms
Side effects of GC?
hyperglycemia (diabetes), blood pressure, osteoporosis, euphoria, cataracts
Leukotrine recpetor antagonists prevent?
aspirin and exercise induced asthma, decrease early and late responses to allergen - also used combined w b-adrenergic agonist for bronchodilation
