Pharmacology
Furosemide is a loop diuretic that primarily inhibits sodium and chloride reabsorption in the proximal and distal tubules and the loop of Henle, producing high-degree diuresis independent of carbonic anhydrase inhibition or aldosterone.
Prednisone is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties that suppresses inflammatory processes (edema, capillary dilatation, leukocyte migration), modifies immune responses, and produces metabolic effects including promotion of gluconeogenesis, protein catabolism, and altered calcium and electrolyte balance.
