Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
BEKYREE (balcinrenone) is a selective mineralocorticoid receptor antagonist that binds to the mineralocorticoid receptor, inhibiting aldosterone-mediated sodium reabsorption and reducing inflammation and fibrosis in the kidney and heart.
Ethacrynic acid inhibits the Na-K-Cl cotransporter (NKCC2) in the thick ascending limb of the loop of Henle, reducing reabsorption of sodium, chloride, and potassium, leading to diuresis.

None.
WARNING: EDECRIN is a potent diuretic which, if given in excessive amounts, can lead to profound diuresis with water and electrolyte depletion. Therefore, careful medical supervision is required, and dose and dose schedule must be adjusted to the individual patient's needs.
Hyperkalemia: Monitor serum potassium regularly; avoid use with strong CYP3A4 inhibitors or potassium supplements.,Acute kidney injury: May occur; assess renal function before initiation.,Adrenal insufficiency: Not studied in patients with adrenal disorders.,Pregnancy: Limited data; avoid use unless benefit outweighs risk.
Ototoxicity: Risk of hearing loss, especially with rapid IV administration or in patients with renal impairment; avoid concurrent use with other ototoxic drugs.,Volume and electrolyte depletion: Profound diuresis leading to dehydration, hypokalemia, hyponatremia, hypochloremia, and metabolic alkalosis.,Hypersensitivity reactions: Rash, eosinophilia, and anaphylaxis.,Gastrointestinal disturbances: Nausea, vomiting, diarrhea, and gastrointestinal bleeding (rare).,Hyperuricemia may precipitate gout.,Use with caution in patients with hepatic cirrhosis due to risk of hepatic encephalopathy.
Concomitant use with strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin),Serum potassium >5.0 m Eq/L at initiation,e GFR <15 m L/min/1.73 m² (not studied),Hypersensitivity to balcinrenone or any excipient
Anuria,Hypersensitivity to ethacrynic acid or any component of the formulation,Severe electrolyte depletion (e.g., hypokalemia, hyponatremia) until corrected,Concurrent use with other ototoxic agents (relative contraindication)
No known food interactions. Avoid grapefruit juice if patient is on concurrent CYP3A4 substrates (though bevacizumab is not metabolized by CYP enzymes). Maintain adequate hydration to reduce risk of constipation, a common side effect.
Avoid excessive intake of high-sodium foods as they can counteract the diuretic effect. Grapefruit juice may increase the risk of ototoxicity; consumption should be limited. Alcohol can exacerbate hypotension and dehydration. Ensure adequate potassium intake through diet (e.g., bananas, oranges) unless directed otherwise by a healthcare provider.
First trimester: Avoid use due to potential teratogenicity (limited human data, animal studies show risk). Second/Third trimester: Use only if benefit outweighs risk; monitor for fetal growth restriction and oligohydramnios.
EDECRIN (ethacrynic acid) is classified as FDA Pregnancy Category B. Limited human data; animal studies have not demonstrated teratogenic effects. However, diuretic use during pregnancy may reduce placental perfusion. Fetal risks include electrolyte disturbances, volume depletion, and possible growth restriction. Use only if clearly needed.
No human data on excretion in breast milk. M/P ratio unknown. Avoid breastfeeding due to potential for adverse effects in nursing infant.
It is not known if ethacrynic acid is excreted in human milk. Due to potential adverse effects in the nursing infant, such as electrolyte imbalance, caution is advised. The manufacturer recommends discontinuing nursing or the drug, taking into account the importance of the drug to the mother. M/P ratio is unknown.
No specific dose adjustments recommended based on pharmacokinetic changes. However, monitor therapeutic effect and adjust dose as needed based on clinical response and tolerability.
Pregnancy may alter pharmacokinetics; however, no specific dose adjustments have been established. Use lowest effective dose and shortest duration. Monitor for hypovolemia and electrolyte imbalances, which may be more pronounced in pregnancy.
BEKYREE (bevacizumab-awwb) is a biosimilar to bevacizumab. Monitor for hypertension, proteinuria, and bleeding. Discontinue 28 days prior to elective surgery. Avoid use in patients with recent hemoptysis or serious hemorrhage. Infusion reactions may occur; premedicate with antihistamines and acetaminophen as per protocol.
EDECRIN (ethacrynic acid) is a potent loop diuretic that, unlike furosemide, is not a sulfonamide and can be used in patients with sulfonamide allergy. It can cause ototoxicity that is often irreversible, especially when given rapidly IV or with other ototoxic drugs like aminoglycosides. Monitor for hypokalemia, hypomagnesemia, and volume depletion. Use with caution in patients with hepatic cirrhosis due to risk of electrolyte-induced encephalopathy.
Tell your doctor if you have a history of bleeding problems, blood clots, or recent surgery.,Avoid taking aspirin or NSAIDs unless prescribed by your doctor, as they increase bleeding risk.,Report any unusual bleeding, coughing up blood, or black/tarry stools immediately.,Women of childbearing age must use effective contraception during therapy and for 6 months after last dose.,Do not breastfeed during treatment and for 6 months after the last dose.,Monitor for signs of hypertension (severe headache, blurred vision) and proteinuria (foamy urine).
Take this medication exactly as prescribed, usually once or twice daily.,Avoid alcohol and limit salt intake to reduce fluid retention.,Weigh yourself daily and report rapid weight gain or loss to your doctor.,Stand up slowly from sitting or lying down to prevent dizziness from low blood pressure.,Notify your doctor immediately if you experience hearing loss, ringing in the ears, or dizziness.,This drug may increase blood sugar; monitor if you have diabetes.,Avoid taking with other ototoxic medications like certain antibiotics without doctor approval.
