Lasix

Generic Name: Furosemide
Class: Loop Diuretics
VA Class: CV702
CAS Number: 54-31-9

• 
  

  Furosemide is a potent diuretic that given in excessive amounts may induce a profound diuresis with water and electrolyte depletion.^{133 e} Careful medical supervision is required; dosage selection and titration should be adjusted to the individual patient’s needs.^{133 e} (See Dosage and Administration.)

  
  

Introduction

A sulfonamide, loop-type diuretic and antihypertensive agent.^{133 e}

Uses for Lasix

Edema

Management of edema associated with CHF, hepatic cirrhosis, and renal disease (e.g., nephrotic syndrome).^{133 e}

Considered a diuretic of choice for most patients with CHF.¹³¹

IV management of acute pulmonary edema (in combination with oxygen and a cardiac glycoside).¹⁵⁰

Hypertension

Management of hypertension (alone or in combination with other classes of antihypertensive agents).^{100 101 109 124 127 133 144}

One of several preferred initial therapies in hypertensive patients with CHF or renal disease.^{100 101 109 124 127 144}

Can be used as monotherapy for initial management of uncomplicated hypertension; however, thiazide diuretics are preferred by JNC 7.^{100 101 124 127 142 143 144}

Lasix Dosage and Administration

General

Edema

• 
  

  Careful etiologic diagnosis should precede the use of any diuretic.^e

  
  


• 
  

  Hospitalization of the patient during initiation of therapy is advisable, especially for patients with hepatic cirrhosis and ascites or chronic renal failure.^{133 e}

  
  


• 
  

  Most experts state that all patients with symptomatic CHF who have evidence for, or a prior history of, fluid retention generally should receive diuretic therapy in conjunction with moderate sodium restriction (≤3 g of sodium daily), an ACE inhibitor, and usually a β-blocker, with or without a cardiac glycoside.¹³¹

  
  


• 
  

  In prolonged diuretic therapy, intermittent use of the drug (e.g., on 2–4 consecutive days each week) may be advisable.^e

  
  

Hypertension

• 
  

  Monitor BP carefully, especially during initial therapy.¹³³

  
  


• 
  

  If added to regimen of a patient receiving another antihypertensive agent, reduce dosage of preexisting therapy by at least 50% initially to avoid severe hypotension; additional dosage adjustment may be required.¹³³

  
  

Administration

Administer orally, IV, or IM.^{133 150}

Oral Administration

Administer orally once (preferably in the morning)^e or twice daily .¹³³

For ease of administration and maximum dosage flexibility in children, consider use of oral solution preparation.¹⁵¹

IV Administration

For solution and drug compatibility information, see Compatibility under Stability.

IV administration may be used in emergency clinical circumstances when a rapid onset of diuresis is desired, or in patients unable to take oral medication or those with impaired GI absorption; replace with oral therapy as soon as possible.^{133 150 e}

Consider the potential risks, when using large parenteral doses; monitor patient closely.^{105 107}

Dilution

For IV infusion, dilute in 5% dextrose, 0.9% sodium chloride, or lactated Ringer’s injection and adjust pH to >5.5.^{150 e}

Whenever possible, use vials instead of ampuls to prepare large doses to prevent large quantities of glass particles from entering the solutions.^e If ampuls must be used, consider filtering through a sterile membrane filter before use to remove any particles that may be present.^e

Rate of Administration

For direct IV injection, administer slowly over a period of 1–2 minutes.^{150 e}

If high-dose parenteral furosemide therapy is necessary, the manufacturer recommends that the drug be administered as a controlled infusion at a rate not exceeding 4 mg/minute in adults.^{150 e}

Dosage

Individualize dosage according to patient’s requirements and response; titrate dosage to gain maximum therapeutic effect while using the lowest possible effective dosage.^e (See Boxed Warning.)

Sensitivity Reactions

Anaphylaxis

Anaphylaxis (e.g., urticaria, angioedema, hypotension) within 5 minutes after IV administration reported.¹⁰²

Systemic Lupus Erythematosus

Possible exacerbation or activation of systemic lupus erythematosus.^{133 150}

Sulfonamide Sensitivity

Patients sensitive to sulfonamides may show allergic reactions to furosemide.^e

Photosensitivity

Photosensitivity may occur.¹³³

Major Toxicities

Ototoxicity

Risk of tinnitus, reversible or permanent hearing impairment increased following IV or IM administration, especially at high dosages,^{133 e} after too-rapid administration,¹³³ in patients with severely impaired renal function, and/or in patients receiving other ototoxic drugs (e.g., aminoglycosides).^{133 e} (See Specific Drugs under Interactions.)

If high-dose IV therapy is indicated, administer by slow IV infusion (e.g., at a rate not exceeding 4 mg/minute in adults).^{133 150}

General Precautions

Fluid, Electrolyte, and Cardiovascular Effects

Excessive diuresis may cause dehydration and blood volume reduction with circulatory collapse and possibly vascular thrombosis and embolism, particularly in elderly patients.¹³³ (See Boxed Warning.)

Risk of orthostatic hypotension, especially with brisk diuresis.^{133 150 151} May be aggravated by concomitant use with alcohol, barbiturates, or narcotics.^{133 151 e}

Risk of hypokalemia, especially with brisk diuresis, inadequate oral electrolyte intake, when cirrhosis is present, or during concomitant use of corticosteroids or ACTH.^{133 150} Concomitant therapy with digitalis may exaggerate metabolic effects of hypokalemia, especially myocardial effects.^{133 150}

Observe carefully for manifestations of fluid and electrolyte depletion (e.g., dryness of mouth, thirst, weakness, lethargy, drowsiness, restlessness, muscle pains or cramps, muscular fatigue, hypotension, oliguria, tachycardia, arrhythmia, nausea, vomiting).¹³³

Endocrine Effects

Possible increased blood glucose and alterations in glucose tolerance tests (with abnormalities of the fasting and 2-hour postprandial sugar); precipitation of diabetes mellitus rarely reported.^{133 150} Monitor urine and blood glucose concentrations periodically in patients with diabetes and those suspected of latent diabetes.^e

Possible hyperuricemia and precipitation of gout;^{133 150} use with caution in patients with a history of gout or elevated serum uric acid concentrations.^e

Patient Monitoring

Monitor regularly for the possible occurrence of blood dyscrasias, liver or kidney damage, or other idiosyncratic reactions.^{133 150}

Serum electrolytes (particularly potassium), CO₂, creatinine and BUN should be determined frequently during the first few months of therapy and periodically thereafter.^{133 150}

Elective Surgery

Discontinue therapy 1 week (oral furosemide) or 2 days (parenteral furosemide) before elective surgery.^e

Specific Populations

Pregnancy

Category C.¹³³

Lactation

Distributed into milk.¹³³ Use with caution.¹³³

Pediatric Use

Risk of persistent patent ductus arteriosus (PDA) may be increased in premature neonates with respiratory distress syndrome (RDS) who receive furosemide during the first weeks of life.^{103 e}

Do not exceed dosage of 1 mg/kg per 24 hours in premature neonates with <31 weeks’ postconception age (gestational age at birth plus postnatal age); risk of potentially toxic furosemide plasma concentrations with higher dosages.¹⁵⁰

Renal calcification reported in severely premature infants treated with IV furosemide for edema due to PDA and hyaline membrane disease; concomitant chlorothiazide therapy may decrease hypercalciuria and dissolve some calculi.¹⁵⁰

Hearing loss reported in neonates; possibly secondary to renal immaturity.^{103 125 126 150}

Oral solutions contain sorbitol; high dosages may cause diarrhea in children.^e

Lasix Pharmacokinetics

Absorption

Bioavailability

Mean oral bioavailability of furosemide from commercially available tablets and oral solution is 64% and 60%, respectively.¹³³

Commercially available tablets and oral solution are bioequivalent.¹³³

Onset

Following oral administration, onset of diuresis occurs within 30 minutes to 1 hour; maximal effect after 1–2 hours.^{133 e}

Following IV administration, diuresis occurs within 5 minutes and peaks within 20–60 minutes.^{150 e}

Onset of diuresis after IM administration occurs somewhat later than after IV administration.¹⁵⁰

Maximum hypotensive effect may not be apparent until after several days of therapy.^e

Duration

Diuretic effect persists 6–8 hours following oral administration and approximately 2 hours following IV administration.^{133 150 e}

Food

Food does not appear to affect diuretic effect.^e

Special Populations

In patients with severely impaired renal function, the diuretic response may be prolonged.^e

Distribution

Extent

Crosses the placenta and is distributed into milk.^e

Plasma Protein Binding

Approximately 95% bound to plasma proteins (mainly albumin) in both normal and azotemic patients.^{133 e}

Elimination

Metabolism

Metabolized in the liver to the defurfurylated derivative, 4-chloro-5-sulfamoylanthranilic acid.^e

Elimination Route

Rapidly excreted in urine by glomerular filtration and by secretion from the proximal tubule.^e

Approximately 50% of an oral dose and 80% of an IV or IM dose are excreted in urine within 24 hours; 69–97% of these amounts is excreted in the first 4 hours.^{150 e} The remainder of the drug is eliminated by nonrenal mechanisms including degradation in the liver and excretion of unchanged drug in the feces.^e

Half-life

Biphasic;^e terminal half-life is approximately 2 hours.¹³³

Special Populations

Hepatic or renal impairment prolongs the elimination half-life of the drug.^e

In patients with marked renal impairment without liver disease, nonrenal clearance is increased to the extent that up to 98% of the drug is cleared within 24 hours.^e

Not removed by hemodialysis.¹³³
