Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Sodium bicarbonate dissociates to provide bicarbonate ion, which neutralizes hydrogen ions and increases blood p H. It also acts as a buffer in acid-base disorders.
Epaned contains enalapril maleate, an angiotensin-converting enzyme (ACE) inhibitor. Enalapril is a prodrug that is hydrolyzed to enalaprilat, which inhibits ACE, thereby reducing angiotensin II formation, decreasing vasoconstriction, aldosterone secretion, and sodium reabsorption.
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
Treatment of hypertension,Heart failure (adjunctive therapy with diuretics and digitalis),Asymptomatic left ventricular dysfunction (to reduce the risk of developing overt heart failure)
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.
0.2 mg/kg intravenously over 5 minutes every 2 hours; typical adult dose 10-20 mg IV.
5–7 minutes (bicarbonate in plasma); short due to rapid equilibration with CO2 and renal excretion. Continuous infusion required for sustained effect.
Terminal elimination half-life is 4-6 hours in adults with normal renal function; prolonged to 10-12 hours in moderate renal impairment (Cr Cl 30-50 m L/min) and 15-20 hours in severe impairment (Cr Cl <30 m L/min).
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).
Enalapril is extensively metabolized in the liver by ester hydrolysis to its active form, enalaprilat. No significant CYP450 metabolism.
Renal: >99% as bicarbonate and carbon dioxide. Minimal biliary/fecal elimination.
Renal excretion of unchanged drug accounts for approximately 30-40% of elimination; biliary/fecal excretion accounts for 50-60% as metabolites and unchanged drug.
<1% (essentially negligible; not significantly protein bound).
Approximately 85-90% bound to serum albumin.
0.4–0.5 L/kg (distributes into extracellular fluid; minimal intracellular penetration).
0.5-0.7 L/kg, indicating distribution primarily into extracellular fluid.
Intravenous: 100%; Oral: ~100% (completely absorbed; but effect on systemic p H is limited due to rapid renal elimination and buffering).
Oral: 70-80% due to first-pass metabolism; Intravenous: 100%.
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.
No adjustment required for renal impairment; drug is hepatically cleared.
No specific dose adjustment based on Child-Pugh score. Use with caution in severe hepatic impairment due to risk of fluid overload and alkalosis.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: use with caution, consider dose reduction by 75%.
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.
0.2 mg/kg intravenously over 5 minutes every 2 hours; maximum single dose 20 mg.
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.
Start at lower end of dosing range (0.1 mg/kg) due to potential for decreased hepatic function and increased sensitivity; monitor for QT prolongation.
No FDA boxed warning exists for sodium bicarbonate.
FDA Warning: When pregnancy is detected, discontinue Epaned as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus.
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.

Avoid high-sodium foods during therapy to prevent fluid overload. No specific food interactions are known.
No specific food interactions. Grapefruit juice does not affect palonosetron metabolism. Avoid alcohol consumption on chemotherapy days as it may worsen nausea or sedation.
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.
Pregnancy category C. No adequate studies in pregnant women. In animal studies, no evidence of teratogenicity at clinically relevant doses. Risk of fetal harm cannot be ruled out. Use only if potential benefit justifies risk.
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.
Not known if excreted in human milk. Caution advised. M/P ratio unknown.
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.
No established dose adjustments for pregnancy. Pharmacokinetic changes in pregnancy are not well characterized; use lowest effective dose.
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.
EPANED (palonosetron) is a 5-HT3 receptor antagonist used for prevention of chemotherapy-induced nausea and vomiting (CINV). It has a longer half-life (~40 hours) than other agents in its class, allowing for single-dose protection. It is not effective for breakthrough nausea. Use caution in patients with electrolyte abnormalities or those taking other QT-prolonging drugs, as palonosetron does not significantly prolong QT interval at standard doses. Administer 30 minutes before chemotherapy. For dexamethasone-sparing regimens, consider single-dose palonosetron with dexamethasone.

"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."
