3
Q
SE: extracellular volume expansion prior diuresis, used carful in heart failure, dehydration, hyperkalemia, hypernatremia, hyponatremia
A
mannitol
4
Q
activate water reabsorption from collecting duct by activating V2 receptors
increases cAMP causing insertion of AQ2 ch on luminal surface
treats: neurogenic DI
A
ADH agonists: ADH & desmopressin
5
Q
inhabit action of ADH & block insertion of water channels on luminal surface
treats: SIADH (abnorm ADH secretion) causes water retention, hyponatremia
A
ADH antagonists: Demeclocycline, Lithium, Conivaptan
