FDA-approved for treatment of infections caused by methicillin-resistant Staphylococcus aureus (MRSA) when other agents are not suitable,Off-label: used for severe staphylococcal and enterococcal infections
FDA-approved: Treatment of metabolic acidosis (e.g., renal tubular acidosis, diabetic ketoacidosis adjunct, cardiac arrest-associated acidosis),Off-label: Alkalinization of urine to prevent uric acid nephropathy, treatment of certain drug intoxications (e.g., tricyclic antidepressants, salicylates), management of acidosis in cardiopulmonary bypass or hemodialysis
5-10 mg/kg intravenously every 8 hours. Maximum total daily dose: 30 mg/kg.
IV: 1 m Eq/kg/dose initial, then 0.5 m Eq/kg/dose every 10 minutes as needed; max 8 m Eq/kg/day. Also given as IV infusion: 50-150 m Eq in 1 L D5W at 1-1.5 L/hour for metabolic acidosis. Oral: 325-2000 mg 1-4 times daily.
3.5-4.5 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment, requiring dose adjustment.
5–7 minutes (bicarbonate in plasma); short due to rapid equilibration with CO2 and renal excretion. Continuous infusion required for sustained effect.
Primarily hepatic metabolism via glucuronidation and biliary excretion; minor renal excretion.
Sodium bicarbonate is not metabolized; it dissociates into sodium and bicarbonate ions in body fluids. Bicarbonate is primarily eliminated via the kidneys (renal excretion) and lungs (conversion to CO2).
Primarily renal (unchanged drug 70-80%); biliary/fecal (15-20%); minor metabolic clearance.
Renal: >99% as bicarbonate and carbon dioxide. Minimal biliary/fecal elimination.
25-30%, primarily to albumin.
<1% (essentially negligible; not significantly protein bound).
0.25-0.35 L/kg, indicating distribution primarily into extracellular fluid.
0.4–0.5 L/kg (distributes into extracellular fluid; minimal intracellular penetration).
Oral: 30-40% (variable due to first-pass metabolism); IM: 80-90%; IV: 100%.
Intravenous: 100%; Oral: ~100% (completely absorbed; but effect on systemic p H is limited due to rapid renal elimination and buffering).
GFR 30-89 m L/min: Administer 5-10 mg/kg IV every 12 hours. GFR 15-29 m L/min: Administer 5-10 mg/kg IV every 24 hours. GFR <15 m L/min: Administer 5-10 mg/kg IV every 48 hours or consider alternative therapy.
No specific dose adjustment for GFR; however, sodium bicarbonate can cause fluid overload and metabolic alkalosis in renal impairment. Use with caution in patients with GFR <30 m L/min; monitor serum sodium and bicarbonate levels closely.
Child-Pugh Class A: No adjustment. Child-Pugh Class B: Reduce dose by 25%. Child-Pugh Class C: Use with caution; consider 50% dose reduction.
No specific dose adjustment based on Child-Pugh score. Use with caution in severe hepatic impairment due to risk of fluid overload and alkalosis.
Infants and children: 10 mg/kg IV every 8 hours. Maximum daily dose: 30 mg/kg. Neonates: 10 mg/kg IV every 12 hours.
IV: 1 m Eq/kg/dose slow IV push (not to exceed 10 m Eq/min) for acute acidosis; may repeat in 10-15 minutes. Oral: 1-5 m Eq/kg/day in divided doses; typical starting dose 1-2 m Eq/kg/day.
Initiate at 5 mg/kg IV every 12 hours, with subsequent dosing based on renal function and clinical response. Monitor for neurotoxicity and nephrotoxicity.
Use lowest effective dose; monitor for fluid overload, electrolyte imbalances, and metabolic alkalosis. Initiate at 25-50% of adult dose and titrate slowly due to decreased renal function and comorbidities.
None
No FDA boxed warning exists for sodium bicarbonate.
Hypersensitivity reactions including anaphylaxis,Hepatotoxicity,Bone marrow suppression (leukopenia, thrombocytopenia),Potential for drug interactions with agents metabolized by CYP450 isoenzymes
Risk of hypernatremia, hyperosmolality, and fluid overload, especially in patients with renal impairment or heart failure.,Paradoxical intracellular acidosis may occur due to rapid CO2 generation.,Extravasation can cause tissue necrosis (administer via central line if concentrated solutions).,Avoid excessive doses; monitor serum electrolytes, p H, and calcium levels.
Hypersensitivity to novobiocin or any component,Severe hepatic impairment,Breastfeeding (due to potential for kernicterus in neonates)
Absolute: Metabolic alkalosis, hypocalcemia (may precipitate tetany), concurrent conditions with alkalosis risk (e.g., vomiting, nasogastric suction).,Relative: Renal failure (risk of sodium and bicarbonate overload), congestive heart failure, hypertension, or other sodium-retaining states.
Avoid grapefruit and grapefruit juice as they may increase ALBAMYCIN levels and risk of toxicity. No other significant food interactions known.
Avoid high-sodium foods during therapy to prevent fluid overload. No specific food interactions are known.
Albamycin is teratogenic in animal studies; human data limited. Risk group: D. First trimester: Associated with teratogenic effects (e.g., cardiac defects) in animals; avoid unless life-threatening. Second trimester: Potential for fetal nephrotoxicity and ototoxicity. Third trimester: Risk of neonatal skeletal abnormalities and hearing loss; avoid near term. Fetal risk outweighs potential benefit.
Sodium bicarbonate is not known to be teratogenic in humans. In animal studies, no teratogenic effects were observed at doses equivalent to human therapeutic doses. However, during pregnancy, especially in the first trimester, use only if clearly needed and potential benefit justifies risk to the fetus. Administration during labor may lead to metabolic alkalosis and hypernatremia in the neonate.
Excreted in human milk; M/P ratio not reported. Potential adverse effects in nursing infants (gastrointestinal disturbance, hypersensitivity). Use with caution; consider alternative therapy. American Academy of Pediatrics suggests use with caution.
Sodium bicarbonate is excreted into breast milk in concentrations similar to plasma. The M/P ratio is approximately 1.0. It is considered compatible with breastfeeding; however, excessive doses could potentially cause metabolic alkalosis in the infant. Use caution with high doses or prolonged therapy.
Increased renal clearance during pregnancy may reduce serum concentrations; therapeutic drug monitoring recommended. For obesity, adjust dose based on actual body weight due to increased volume of distribution. Dose reduction may be needed in renal impairment common in preeclampsia. No standard adjustment guidelines; individualize based on clinical response and serum levels.
No specific dose adjustment is required for pregnancy based on pharmacokinetic changes. However, close monitoring of electrolytes and acid-base status is recommended due to altered physiological states (e.g., increased plasma volume, renal function changes). Individualize dosing based on patient's acid-base and electrolyte status.
ALBAMYCIN is a novel antibiotic with potent activity against Gram-negative bacteria, but it requires therapeutic drug monitoring due to a narrow therapeutic index. It is primarily renally excreted; adjust dose in renal impairment (Cr Cl <30 m L/min). Monitor for ototoxicity and nephrotoxicity, especially in elderly and those on concurrent loop diuretics. Intravenous infusion must be administered over at least 60 minutes to reduce infusion-related reactions.
Sodium bicarbonate in plastic container is used for metabolic acidosis treatment. Avoid rapid administration in neonates due to risk of hypernatremia and intraventricular hemorrhage. Monitor serum sodium, bicarbonate, and p H during infusion. Do not administer with calcium-containing solutions to prevent precipitation. Plastic containers may leach DEHP; use with caution in pediatric patients.

No interactions on record
"Mycophenolic acid, a prodrug of mycophenolate mofetil, undergoes enterohepatic recirculation and is absorbed in the stomach and proximal small intestine. Sodium bicarbonate, by raising gastric pH, can reduce the dissolution and absorption of mycophenolic acid, leading to decreased systemic exposure and potentially reduced immunosuppressive efficacy. This interaction may increase the risk of transplant rejection when used concurrently."
"Sodium bicarbonate, an alkalizing agent, can increase the gastric pH, which may reduce the dissolution and absorption of topically administered clobetasol propionate if swallowed inadvertently. However, this interaction is not clinically significant for topical application, as systemic absorption of clobetasol is minimal. The theoretical decrease in bioavailability is unlikely to affect efficacy or safety."
"Perphenazine, a phenothiazine antipsychotic, can reduce the absorption of sodium bicarbonate by delaying gastric emptying and increasing gastrointestinal transit time. This results in decreased systemic availability of bicarbonate, potentially attenuating its alkalinizing effect and compromising its efficacy in conditions requiring urinary alkalinization or systemic acidosis correction."
