BEKYREE vs BUMEX
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.
Bumetanide inhibits the Na-K-2Cl symporter (NKCC2) in the thick ascending limb of the loop of Henle, reducing reabsorption of sodium, chloride, and potassium, leading to increased diuresis.

1 mg/kg intravenously every 4 weeks; maximum dose 100 mg.
0.5-2 mg orally once daily; if inadequate response, may increase to 2-4 mg once daily or twice daily. Maximum 10 mg/day. IV: 0.5-1 mg IV over 1-2 minutes; may repeat every 2-3 hours up to 10 mg/day.
Terminal elimination half-life: 12 hours (range 10-14 h); prolonged in renal impairment (up to 30 h in Cr Cl <30 m L/min)
Terminal elimination half-life: 1.5–2 hours in normal renal function; prolonged to 2.5–4 hours in severe renal impairment (Cr Cl <20 m L/min).
Primarily metabolized by CYP3A4; minor contributions from CYP2C8 and CYP2C9.
Primarily metabolized by the liver via cytochrome P450 enzymes, including CYP2C9 and CYP3A4.
Renal: 70% (unchanged drug), Biliary/fecal: 30% (metabolites and unchanged drug)
Renal: 80% as unchanged drug; biliary/fecal: 15% as metabolites; total renal elimination accounts for ~85% of clearance.
95% bound to albumin and alpha-1-acid glycoprotein
Bumetanide is 94–96% bound to plasma proteins (primarily albumin).
0.8-1.2 L/kg (indicates extensive tissue distribution)
0.15–0.22 L/kg; indicates primarily extracellular distribution.
Oral: 60% (range 50-70%; first-pass metabolism reduces bioavailability)
Oral bioavailability: 80–100% (mean ~95%).
No dose adjustment required for mild to moderate renal impairment (e GFR ≥30 m L/min/1.73 m²). Not recommended for severe renal impairment (e GFR <30 m L/min/1.73 m²) due to lack of data.
e GFR <20 m L/min/1.73 m²: Avoid loop diuretics; consider alternative. No adjustment for mild to moderate renal impairment, but monitor response. In severe renal failure, may require higher doses due to reduced tubular secretion.
Child-Pugh A: no adjustment; Child-Pugh B: 0.5 mg/kg intravenously every 4 weeks; Child-Pugh C: not recommended.
Child-Pugh Class B or C: Reduce initial dose by 50% due to impaired metabolism and increased risk of volume depletion. Titrate cautiously.
Safety and efficacy not established in pediatric patients under 18 years.
Infants/Children: Oral: 0.015-0.1 mg/kg/dose once daily; maximum 10 mg/day. IV/IM: 0.015-0.1 mg/kg/dose every 12-24 hours; maximum 0.5 mg/kg/dose. Neonates: 0.01-0.05 mg/kg/dose every 24-48 hours.
No specific dose adjustment required; consider age-related renal function and comorbidities.
Start at 0.5 mg orally once daily; increase cautiously due to enhanced pharmacodynamic effects and higher risk of electrolyte disturbances, volume depletion, and ototoxicity. Monitor renal function and electrolytes closely.
None.
Bumetanide is a potent diuretic; if given in excessive amounts, can lead to profound diuresis with water and electrolyte depletion. Therefore, careful medical supervision is required, and dose and dosage schedule must be adjusted to 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.
Electrolyte depletion (hypokalemia, hyponatremia, hypochloremia),Dehydration and hypovolemia,Ototoxicity (especially with rapid injection or in renal impairment),Excessive diuresis causing hypotension and thromboembolic events,May increase serum uric acid levels and precipitate gout,Risk of hypokalemia in patients with cirrhosis and ascites
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,Hepatic coma or severe electrolyte depletion until condition is corrected,Hypersensitivity to bumetanide or sulfonamides (cross-sensitivity possible)
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 salt intake; no specific food interactions reported. Avoid licorice as it may worsen hypokalemia. Grapefruit juice may increase bumetanide levels; use caution.
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.
Bumetanide (BUMEX) is a loop diuretic classified as FDA Pregnancy Category C. Animal studies have shown embryocidal effects and delayed ossification at high doses. Human data are limited; no well-controlled studies exist. First trimester: theoretical risk based on animal data; avoid unless essential. Second/third trimesters: may cause maternal hypovolemia, decreased placental perfusion, and fetal oliguria; use only if clearly needed and monitor amniotic fluid volume. Neonatal risks include electrolyte imbalances and ototoxicity if used close to delivery.
No human data on excretion in breast milk. M/P ratio unknown. Avoid breastfeeding due to potential for adverse effects in nursing infant.
Bumetanide is excreted into human milk in low concentrations. The milk-to-plasma (M/P) ratio is approximately 0.05-0.10. Based on limited data, amounts ingested by breastfed infants are unlikely to cause adverse effects. However, due to potential risk of hypersensitivity, electrolyte disturbances, or diuresis in the infant, caution is advised, especially in premature or renal-impaired infants. Alternative diuretics with more safety data may be preferred.
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 bumetanide pharmacokinetics due to increased plasma volume, renal blood flow, and glomerular filtration rate. Higher doses may be required to achieve the same diuretic effect. However, no standard dose adjustment guidelines exist; use the lowest effective dose and titrate based on clinical response, monitoring for electrolyte disturbances and volume depletion. In severe preeclampsia or renal impairment, dose may need reduction. Close therapeutic drug monitoring is not routinely available; clinical monitoring of diuresis and electrolytes guides dosing.
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.
Bumetanide is a loop diuretic approximately 40 times more potent than furosemide; onset of diuresis within 30-60 minutes after oral administration. Monitor for ototoxicity, especially with rapid IV administration or concurrent use of other ototoxic drugs. Hypokalemia is a common adverse effect; consider potassium supplementation or concurrent use of potassium-sparing diuretics. Contraindicated in anuria, hepatic coma, and severe electrolyte depletion. May cause hyperuricemia and precipitate gout attacks.
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).
