Furosemide has a rapid onset of action, and it is this characteristic that makes it the drug of choice for managing the emergent patient with respiratory distress associated with cardiogenic or pulmonary edema. Drug formularies and other references cite dosages for furosemide - administered by the intravenous (IV) and intramuscular (IM) routes - for treating patients with acute cardiogenic or pulmonary edema. Although there are references for administering this drug subcutaneously (SC), it is not generally listed as a suggested route of administration for patients with acute, severe pulmonary edema.
This week's Evidence Based Update reveals the findings of a study that compared the diuretic effects of furosemide - when administered subcutaneously - to other routes of administration including a constant rate infusion, as well as the intravenous, intramuscular, and oral routes.
