Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Sodium succinate is a salt of succinic acid, which serves as an intermediate in the tricarboxylic acid (TCA) cycle. It acts as a metabolic supplement, enhancing cellular respiration and energy production by providing substrate for the TCA cycle. It also exhibits antioxidant properties by scavenging free radicals.
Calcium gluceptate is a calcium salt that dissociates to provide calcium ions, which are essential for various physiological processes including nerve conduction, muscle contraction, blood coagulation, and cardiac function. It acts as a calcium replenisher.
Adjunctive therapy in the treatment of acute myocardial infarction and ischemic heart disease,Off-label: Use in chronic fatigue syndrome, as a hepatoprotective agent, and in various forms of metabolic acidosis
Treatment of hypocalcemia,Calcium supplementation in patients requiring parenteral calcium,Treatment of hypermagnesemia,Cardiac resuscitation (as an adjunct),Treatment of calcium channel blocker overdose
No established standard dosing for sodium succinate as a therapeutic agent; it is used as a pharmaceutical excipient or buffering agent in intravenous formulations. For buffering purposes, typical concentrations range from 0.5% to 2% in injection solutions, administered intravenously at rates adjusted per clinical need.
IV: 2-4 mg/kg elemental calcium (5-10 m L of 0.45 m Eq/m L solution) administered slowly over 10-20 minutes. May repeat if needed. Maximum dose: 20 m L per infusion.
5-10 minutes; rapid elimination limits systemic effects.
Terminal elimination half-life: 2-4 hours (normal renal function); prolonged to 12-24 hours in renal impairment.
Sodium succinate is metabolized via the tricarboxylic acid (TCA) cycle to carbon dioxide and water, with energy release. No specific cytochrome P450 enzymes are involved.
Calcium gluceptate is not metabolized; it dissociates into calcium ions and gluceptate. Calcium ions are excreted primarily in feces and urine, with renal handling involving reabsorption and secretion.
Renal excretion of unchanged drug; less than 5% biliary/fecal.
Renal: >90% excreted unchanged in urine. Biliary/fecal: <5%.
Not significantly protein bound (<5%).
~45% bound to albumin.
0.3-0.5 L/kg; limited to extracellular fluid.
0.15-0.25 L/kg; represents distribution mainly in extracellular fluid.
Not applicable; administered intravenously; no oral bioavailability due to rapid metabolism.
IV: 100%; IM: not well characterized; oral: negligible (absorbed poorly, systemic bioavailability <1% as calcium gluceptate dissociates in GI tract).
No renal dose adjustment data available; sodium succinate is not renally excreted in significant amounts and is unlikely to accumulate in renal impairment, but caution with sodium load in severe renal dysfunction.
GFR >50: No adjustment. GFR 30-50: Reduce dose by 25%. GFR <30: Reduce dose by 50% and monitor serum calcium closely. Dialysis: Dose after hemodialysis.
No hepatic dose adjustment data available; no expected impact of hepatic impairment on sodium succinate disposition.
No dose adjustment required for hepatic impairment. However, monitor ionized calcium in severe hepatic failure due to altered binding proteins.
No established pediatric dosing; use as excipient follows adult concentration guidelines with weight-based fluid calculations.
Neonates and infants: 100-200 mg elemental calcium/kg/day IV divided every 6 hours. Children: 200-500 mg elemental calcium/kg/day IV divided every 6 hours. Maximum: 1 g elemental calcium per dose.
No specific geriatric dose adjustment; consider sodium load and renal function in elderly patients with comorbidities.
Use lower initial doses (e.g., 1-2 mg/kg elemental calcium) due to reduced renal function and increased risk of hypercalcemia. Monitor serum calcium and phosphate levels.
None.
No FDA black box warning.
Use with caution in patients with renal impairment due to sodium content; monitor serum sodium levels. May cause transient hypotension or hypertension. Avoid rapid intravenous administration to prevent adverse cardiac events.
Risk of hypercalcemia, especially in patients with renal impairment,Avoid rapid intravenous administration to prevent cardiac arrest,Use with caution in patients with sarcoidosis or digitalis toxicity,Monitor serum calcium levels during therapy,Extravasation may cause tissue necrosis
Hypersensitivity to sodium succinate; severe hypernatremia; edema with sodium retention; severe hypertension; and in patients with metabolic alkalosis.
Hypercalcemia,Hypersensitivity to calcium gluceptate or any component,Ventricular fibrillation,Patients with known calcium-containing calculi
No known food interactions.
Avoid high-calcium foods (dairy, fortified cereals) during acute therapy to prevent hypercalcemia. Limit vitamin D-rich foods (fatty fish, fortified milk). Do not take oral calcium within 1 hour of iron or thyroid medications. Avoid excessive caffeine and alcohol.
No human or animal data available; sodium succinate is a Krebs cycle intermediate with essential metabolic roles; theoretical fetal risk is low, but administration during pregnancy should be cautious and only if clearly needed.
Calcium gluceptate is a calcium salt used for calcium supplementation. No specific teratogenic effects are reported; calcium is essential for fetal development. First trimester: No increased risk of major malformations. Second and third trimesters: Adequate intake supports fetal skeletal mineralization; excess may cause hypercalcemia in the infant. No known teratogenicity.
No data on excretion in human milk; M/P ratio unknown; sodium succinate is endogenous and likely present in milk at low concentrations; caution advised.
Calcium gluceptate is considered safe during breastfeeding. Calcium is naturally present in breast milk; supplementation does not significantly alter milk calcium levels. M/P ratio not established, but endogenous calcium transport suggests minimal risk. Use with caution in mothers with hypercalcemia.
No pharmacokinetic data in pregnancy; dose adjustments not established; use standard dosing based on clinical indication.
No specific dose adjustment required in pregnancy; maintain recommended daily intake (1000-1300 mg elemental calcium). Pharmacokinetic changes in pregnancy (increased absorption, renal clearance) may slightly alter requirements, but standard doses are safe. Intravenous use should be adjusted based on serum calcium monitoring.
Sodium succinate is used as a component of succinylated gelatin solutions for volume expansion. Monitor for hypernatremia and metabolic alkalosis due to succinate metabolism. Avoid in patients with severe renal impairment.
Calcium gluceptate is used for acute hypocalcemia, hyperkalemia cardiotoxicity, and hypermagnesemia. Administer IV slowly (0.5-1 m L/min) to avoid arrhythmias; monitor ECG during infusion. Do not mix with bicarbonate, phosphate, or sulfate-containing solutions. Extravasation causes tissue necrosis; use central line for peripheral therapy. Correct hypomagnesemia before calcium therapy to prevent refractory hypocalcemia.
