Addison's disease. Mode of Action: Furosemide inhibits reabsorption of Na and chloride mainly in the medullary portion of the ascending Loop of Henle. Excretion of potassium and ammonia is also increased while uric acid excretion is reduced. It increases plasma-renin levels and secondary hyperaldosteronism may result. Furosemide reduces BP in hypertensives as well as in normotensives. It also reduces pulmonary oedema before diuresis has set in. Precaution: Prostatic hyperplasia. Hepatic or renal impairment, gout, DM, impaired micturition. Infusion rate should not exceed 4 mg/min to reduce the risk of ototoxicity. Monitor fluid and electrolyte balance and renal function. May lower serum levels of calcium and magnesium, thus serum levels should be monitored. Pregnancy and lactation. Lactation: Drug excreted into breast milk; use with caution; may inhibit lactation Side Effect: >10% Hyperuricemia (40%), Hypokalemia (14-60%) Frequency Not Defined Hyponatraemia, hypochloraemic alkalosis, headache, drowsiness, muscle cramps, hypotension, dry mouth, thirst, weakness, lethargy, restlessness, oliguria, GI disturbances, hypovolaemia, dehydration, hyperuricaemia, acute generalised exanthematous pustulosis, drug rash w/ eosinophilia and systemic symptoms, reversible or irreversible hearing impairment, deafness, tinnitus, severe anaphylactic or anaphylactoid reactions (e.g. w/ shock), Stevens-Johnson syndrome, toxic epidermal necrolysis; increased liver enzyme, cholesterol and triglyceride serum levels. Potentially Fatal: Serious cardiac arrhythmias. Pregnancy Category Note: Pregnancy category: C; treatment during pregnancy necessitates monitoring of fetal growth because of risk for higher fetal birth weights Lactation: Drug excreted into breast milk; use with caution; may inhibit lactation Interaction: Analgesics reduce natriuretic action of furosemide. Antagonises hypoglycaemic agents and drugs used for gout. Hyperglycaemia with antihypertensive agent diazoxide. Antagonises muscle relaxants. Increased risk of ototoxicity when used with aminoglycosides especially in renal impairment. May enhance nephrotoxicity of cephalosporins. Effects of antihypertensives enhanced. Action antagonised by corticosteroids. Phenytoin and indometacin may reduce effects of furosemide. Potentially Fatal: May provoke severe hypotensive response with ACE inhibitors. NSAIDs inhibit diuretic and antihypertensive effects. Increased incidence of premature beats with cardiac glycosides.
