高血壓 (diuretics) 利尿劑 (loop diuretics)
Edema: Management of edema associated with heart failure, cirrhosis of the liver (ie, ascites), or renal disease (including nephrotic syndrome); acute pulmonary edema

Inhibits reabsorption of sodium and chloride in the ascending loop of Henle and proximal and distal renal tubules, interfering with the chloride-binding cotransport system, thus causing increased excretion of water, sodium, chloride, magnesium, and calcium

1. Anuria
2. History of hypersensitivity to furosemide

Use with caution due to the potential reduction in placental blood flow.

The manufacturer recommends that caution be used if administered to a breastfeeding woman.

Edema:
1. Naive to loop diuretics: Initial 20-40 mg once then titrate as needed to an effective dose
2. Refractory edema or acute decompensation in patients taking oral loop diuretics: Initial 1 to 2.5 times the total daily oral maintenance dose once (eg, a patient taking oral furosemide 40 mg twice daily at home [80 mg/day] can be given 80 mg to 200 mg IV as an initial bolus); then titrate as needed to an effective dose

1. eGFR >30 mL/minute/1.73 m2: No dosage adjustment necessary
2. eGFR ≤30 mL/minute/1.73 m2: Higher doses may be required to achieve desired diuretic response due to decreased secretion into the tubular fluid. However, single doses >160 to 200 mg IV (or oral equivalent) are unlikely to result in additional diuretic effect
