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.
Uricosuric agent; inhibits renal tubular reabsorption of uric acid, increasing uric acid excretion and lowering serum urate levels.
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 chronic gout,Prophylaxis of acute gouty attacks during initiation of allopurinol or uricosuric therapy,Off-label: Prevention of calcium oxalate calculi in hyperuricosuric patients
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.
200-400 mg orally twice daily
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 approximately 4–6 hours for the parent drug; active sulfide metabolite has a half-life of 12–16 hours. Clinically, twice-daily dosing maintains therapeutic levels.
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 hepatic oxidation and glucuronidation; minor CYP450 involvement.
Renal: >99% as bicarbonate and carbon dioxide. Minimal biliary/fecal elimination.
Renal excretion: approximately 50% of the dose as unchanged drug and its active sulfide metabolite via glomerular filtration and tubular secretion; biliary/fecal: ~30%, primarily as metabolites.
<1% (essentially negligible; not significantly protein bound).
99% bound, primarily to albumin.
0.4–0.5 L/kg (distributes into extracellular fluid; minimal intracellular penetration).
0.15–0.3 L/kg, indicating limited extravascular distribution; primarily remains in plasma and extracellular fluid.
Intravenous: 100%; Oral: ~100% (completely absorbed; but effect on systemic p H is limited due to rapid renal elimination and buffering).
Oral: Approximately 90% absorbed, but extensive first-pass metabolism reduces systemic bioavailability of parent drug to 30–40%; active sulfide metabolite contributes to efficacy.
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.
Contraindicated if Cr Cl <30 m L/min. For Cr Cl 30-50 m L/min, reduce dose by 50%. For Cr Cl >50 m L/min, no adjustment.
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: avoid use.
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.
Not recommended for use in pediatric patients due to lack of safety and efficacy data.
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 low end of dosing range (200 mg twice daily); monitor renal function. Caution due to increased sensitivity and renal impairment.
No FDA boxed warning exists for sodium bicarbonate.
None.
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.
Acute gouty attacks may occur during initiation; prophylactic colchicine or NSAIDs recommended,Monitor renal function; dose adjustment in renal impairment,Avoid in patients with high urinary uric acid output to prevent uric acid stones,May potentiate warfarin; monitor INR,Cross-allergenicity with sulfonamides possible
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.
Severe renal impairment (Cr Cl <50 m L/min),History of hypersensitivity to sulfinpyrazone or sulfonamides,Active peptic ulcer disease,Blood dyscrasias,Uric acid nephropathy or stone formation
Avoid high-sodium foods during therapy to prevent fluid overload. No specific food interactions are known.
Avoid alcohol as it increases uric acid levels and may decrease drug efficacy. Maintain adequate hydration; avoid excessive intake of high-purine foods (e.g., organ meats, sardines, anchovies) to help control gout.
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.
Anturane (sulfinpyrazone) is a uricosuric agent. There are no adequate and well-controlled studies in pregnant women. In animal studies, no teratogenic effects were observed at doses up to 10 times the human dose. However, due to its potential to inhibit platelet aggregation, use during pregnancy, especially near term, may increase the risk of maternal and fetal hemorrhage. First trimester: No specific fetal risks identified, but caution advised. Second trimester: Risks unclear; avoid unless necessary. Third trimester: Potential for premature closure of ductus arteriosus (unlikely as it is not an NSAID) and bleeding risk; avoid near term.
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.
Sulfinpyrazone is excreted into human milk in small amounts. The milk-to-plasma (M/P) ratio is not well established but is likely low (<0.2). Due to potential adverse effects in the nursing infant (e.g., bleeding risk, interference with platelet function), caution is recommended. The benefits of breastfeeding should be weighed against the potential risks, and alternative therapies considered.
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.
Pregnancy can alter pharmacokinetics of drugs due to increased plasma volume, renal blood flow, and hepatic metabolism. For sulfinpyrazone, no specific dose adjustment guidelines are established for pregnancy. Given its uricosuric action, the increased glomerular filtration rate during pregnancy may enhance clearance, potentially requiring higher doses to maintain therapeutic effect. However, due to potential risks, use should be avoided if possible. If used, monitor serum uric acid levels and adjust dose accordingly, starting with the 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.
Anturane (sulfinpyrazone) is a uricosuric agent used for chronic gout. It is contraindicated in patients with peptic ulcer disease due to GI irritation. Monitor renal function and uric acid levels. Avoid use in patients with a history of uric acid stones; maintain high fluid intake to prevent stone formation. Not effective in acute gout attacks. Discontinue at least 48 hours before surgery to avoid bleeding risk due to antiplatelet effects.

"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."
