BEKYREE vs DEMADEX
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.
Inhibits the Na-K-2Cl symporter in the thick ascending limb of the loop of Henle, reducing reabsorption of sodium, chloride, and potassium, leading to increased urine output.

Edema associated with heart failure, hepatic cirrhosis, and renal disease,Hypertension (off-label)
1 mg/kg intravenously every 4 weeks; maximum dose 100 mg.
Oral: 5-10 mg once daily; may increase to 20 mg once daily if needed. IV: 5-10 mg once daily; may increase to 20 mg once daily if needed. Maximum dose: 40 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)
The terminal elimination half-life is approximately 4 hours (range 2-8 hours) in patients with normal renal function. In renal impairment (creatinine clearance <30 m L/min), half-life is prolonged to 10-12 hours due to reduced renal clearance. In hepatic cirrhosis, half-life may be extended to 8-9 hours due to decreased metabolism.
Primarily metabolized by CYP3A4; minor contributions from CYP2C8 and CYP2C9.
Primarily hepatic via CYP450 enzymes, with minimal renal clearance.
Renal: 70% (unchanged drug), Biliary/fecal: 30% (metabolites and unchanged drug)
Approximately 50% of the absorbed dose is excreted unchanged in the urine via glomerular filtration and active tubular secretion. The remainder undergoes hepatic metabolism to glucuronide conjugates and minor oxidative metabolites, with biliary excretion of metabolites (about 30-40% of the dose) eliminated in feces. Renal clearance is the primary route for the parent drug.
95% bound to albumin and alpha-1-acid glycoprotein
Torsemide (DEMADEX) is extensively bound to plasma proteins, primarily albumin, with a protein binding of >99%.
0.8-1.2 L/kg (indicates extensive tissue distribution)
The apparent volume of distribution (Vd) is approximately 0.16 L/kg (range 0.12–0.20 L/kg), indicating distribution primarily within extracellular fluid. Vd is increased in conditions with expanded extracellular volume (e.g., heart failure, cirrhosis, nephrotic syndrome).
Oral: 60% (range 50-70%; first-pass metabolism reduces bioavailability)
Oral bioavailability is approximately 80–90%, with minimal first-pass metabolism. Absorption is rapid and not significantly affected by food.
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.
GFR <20 m L/min/1.73 m²: Use with caution; may require dose reduction or discontinuation due to accumulation. GFR 20-50: No adjustment needed. GFR >50: No adjustment.
Child-Pugh A: no adjustment; Child-Pugh B: 0.5 mg/kg intravenously every 4 weeks; Child-Pugh C: not recommended.
Child-Pugh A: No adjustment. Child-Pugh B: Reduce dose by 50% or extend interval. Child-Pugh C: Avoid use or reduce dose by 75%.
Safety and efficacy not established in pediatric patients under 18 years.
Neonates and infants: 0.1-0.2 mg/kg/dose IV/IM once daily. Children: Oral: 0.5-1 mg/kg once daily; IV/IM: 0.1-0.2 mg/kg/dose once daily. Maximum: 5 mg/day.
No specific dose adjustment required; consider age-related renal function and comorbidities.
Start at lower end of dose range (2.5-5 mg orally once daily); titrate slowly due to increased sensitivity and renal impairment risk.
None.
None.
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.
Hypotension and volume depletion,Electrolyte imbalances (hypokalemia, hyponatremia, hypochloremia),Ototoxicity (especially with rapid IV administration or high doses),Hyperuricemia,Sulfonamide allergy cross-reactivity
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,Severe electrolyte depletion,Hypersensitivity to sulfonamides or bumetanide (Demadex is a sulfonamide derivative)
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 licorice intake (glycyrrhizin) as it can exacerbate hypokalemia. Limit sodium-rich foods (processed foods, canned soups) to enhance diuretic effect and control edema. Increase potassium-rich foods (bananas, oranges, potatoes) unless on a potassium-sparing medication. Avoid grapefruit juice as it may affect metabolism.
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.
DEMADEX (torsemide) is a loop diuretic. Human data are limited. In animal studies, high doses caused fetal resorptions and maternal toxicity. First trimester: insufficient human data; avoid unless benefit outweighs risk. Second/third trimester: risk of fetal oligohydramnios, renal impairment, and hypovolemia; 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.
Torsemide is excreted in breast milk in small amounts; M/P ratio not reported. Due to potential for diuresis, electrolyte imbalance, and allergic reactions in the infant, caution is recommended. Alternative diuretics with more safety data are 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.
Dosing may need adjustment due to increased plasma volume and GFR in pregnancy. Start at lowest effective dose. Monitor diuretic response and electrolyte balance; dose titration may be required. Postpartum, drug elimination may return to prepregnancy kinetics.
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.
DEMADEX (torsemide) is a loop diuretic with high bioavailability (80-100%) and a longer half-life (3-4 hours) than furosemide, allowing once-daily dosing. It is primarily metabolized by CYP2C9, so caution is needed with CYP2C9 inhibitors like amiodarone. Monitor for ototoxicity at high doses or rapid infusion. Hypokalemia risk persists; consider potassium supplementation or aldosterone antagonist. Use cautiously in sulfonamide allergy due to potential cross-sensitivity.
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 DEMADEX exactly as prescribed, usually once daily in the morning to avoid nighttime urination.,Weigh yourself daily and report sudden weight gain or loss of more than 2-3 pounds in a day.,Avoid alcohol and beverages containing caffeine as they may increase dehydration.,Do not take DEMADEX with licorice (which can worsen hypokalemia) or with high-sodium antacids.,Report signs of hearing loss, ringing in the ears, dizziness, or muscle cramps immediately.,Stand up slowly to prevent dizziness from low blood pressure.,Monitor for signs of dehydration: dry mouth, thirst, infrequent urination.
