NICOLAR vs BEKYREE
Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Niacin (nicotinic acid) reduces hepatic production of VLDL and LDL by inhibiting diacylglycerol acyltransferase-2 (DGAT2) and decreasing free fatty acid mobilization from adipose tissue via activation of GPR109A (HM74A) receptor, leading to reduced triglyceride and LDL cholesterol synthesis. It also raises HDL cholesterol by decreasing hepatic clearance of apo A-I.
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.

NICOLAR (niacin extended-release) is typically initiated at 500 mg orally once daily at bedtime, after a low-fat snack. The dose is increased by 500 mg every 4 weeks as tolerated, up to a maximum of 2000 mg once daily.
1 mg/kg intravenously every 4 weeks; maximum dose 100 mg.
Terminal elimination half-life is 14-24 hours in adults with normal renal function; clinically, this supports twice-daily dosing. In moderate renal impairment (Cr Cl 30-59 m L/min), half-life extends to 24-36 hours, requiring dose adjustment.
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)
Extensively metabolized in the liver via two pathways: conjugation with glycine (major) to form nicotinuric acid, and N-methylation to N-methylnicotinamide. Also undergoes oxidation to nicotinamide N-oxide. CYP2E1 may be involved in some metabolic steps.
Primarily metabolized by CYP3A4; minor contributions from CYP2C8 and CYP2C9.
Primarily renal (60-70% as unchanged drug and metabolites), with 10-20% biliary/fecal. Hepatic metabolism to inactive metabolites accounts for ~30% of elimination.
Renal: 70% (unchanged drug), Biliary/fecal: 30% (metabolites and unchanged drug)
Approximately 90% bound to human serum albumin, primarily to albumin and to a lesser extent to alpha-1-acid glycoprotein.
95% bound to albumin and alpha-1-acid glycoprotein
Volume of distribution is 1.5-2.5 L/kg, indicating extensive tissue distribution and high extravascular penetration, particularly into the respiratory tract.
0.8-1.2 L/kg (indicates extensive tissue distribution)
Oral: 30-60% due to first-pass metabolism. Inhaled: 10-20% reaching systemic circulation (majority acts locally with high lung deposition).
Oral: 60% (range 50-70%; first-pass metabolism reduces bioavailability)
For patients with GFR <30 m L/min, reduce maximum dose to 1000 mg once daily due to increased risk of toxicity. For GFR 30-60 m L/min, no dose adjustment is required but monitor closely. No specific guidelines for dialysis.
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.
Contraindicated in patients with Child-Pugh class B or C cirrhosis. For Child-Pugh class A (mild impairment), initiate at 500 mg once daily and titrate cautiously, with maximum dose not exceeding 1000 mg once daily. Monitor liver function tests frequently.
Child-Pugh A: no adjustment; Child-Pugh B: 0.5 mg/kg intravenously every 4 weeks; Child-Pugh C: not recommended.
Not approved for use in pediatric patients below 16 years of age for dyslipidemia. Safety and efficacy have not been established.
Safety and efficacy not established in pediatric patients under 18 years.
No specific dose adjustment is recommended solely based on age. However, elderly patients may have reduced renal function and increased risk of adverse effects (e.g., flushing, hyperglycemia). Initiate at the lowest starting dose (500 mg once daily) and titrate slowly. Monitor renal function and metabolic parameters closely.
No specific dose adjustment required; consider age-related renal function and comorbidities.
Severe hepatotoxicity, including fulminant hepatic necrosis, has occurred with sustained-release formulations. Do not substitute for equivalent doses of immediate-release niacin.
None.
Hepatotoxicity: Monitor liver function tests; discontinue if persistent elevations or signs of hepatic injury.,Hyperuricemia and gout: May increase uric acid levels; use with caution in patients predisposed to gout.,Peptic ulcer: Niacin may reactivate or exacerbate peptic ulcer disease.,Facial flushing (prostaglandin-mediated): To reduce, take with aspirin 30 minutes prior, or use extended-release formulations.,Increased bleeding risk when used with anticoagulants.,Monitor glucose levels in diabetic patients; niacin may impair glucose tolerance.
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.

Avoid high-fat meals with the dose, as they may increase the risk of flushing. Alcohol and hot beverages should be avoided close to dosing, as they can exacerbate flushing. Grapefruit juice has no significant interaction. Maintain a consistent diet to avoid fluctuations in blood glucose.
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.
NICOLAR (niacin) is classified as FDA Pregnancy Category C. Adverse effects have been observed in animal reproduction studies, but no adequate human studies exist. First trimester: potential risk based on animal data; use only if benefit outweighs risk. Second and third trimesters: no known specific risks but limited data; avoid high doses due to possible maternal hepatotoxicity and hyperglycemia.
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.
Niacin is excreted into breast milk; M/P ratio not reported. Concentrations are low but caution is advised due to potential for high doses to cause adverse effects in the infant. Monitor infant for flushing, GI upset, or hepatotoxicity.
No human data on excretion in breast milk. M/P ratio unknown. Avoid breastfeeding due to potential for adverse effects in nursing infant.
No specific dose adjustments are recommended for pregnancy; however, due to increased plasma volume and clearance, therapeutic efficacy may require monitoring. Use the lowest effective dose and monitor clinical response. Avoid extended-release formulations due to higher hepatotoxicity risk.
No specific dose adjustments recommended based on pharmacokinetic changes. However, monitor therapeutic effect and adjust dose as needed based on clinical response and tolerability.
NICOLAR is a brand name for niacin (nicotinic acid) extended-release. Doses should be taken at bedtime with a low-fat snack to reduce flushing.
