Calcium gluconate provides calcium ions, which are essential for normal cardiac function, nerve transmission, and muscle contraction. In hyperkalemia, calcium antagonizes the cardiotoxic effects of potassium by stabilizing the cardiac cell membrane.
Aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, causing misreading of m RNA and inhibiting bacterial protein synthesis.
Emergency treatment of hypocalcemia,Treatment of hypermagnesemia,Treatment of calcium channel blocker overdose,Treatment of hyperkalemia (as a cardioprotective agent),Off-label: Treatment of hydrofluoric acid burns,Off-label: Treatment of black widow spider envenomation
Treatment of serious gram-negative bacterial infections (e.g., Pseudomonas aeruginosa, Escherichia coli, Klebsiella species),Used in combination for severe infections such as sepsis, pneumonia, complicated urinary tract infections, and intra-abdominal infections
1-2 g calcium gluconate (9.3-18.6 m Eq calcium) intravenously over 10-20 minutes, may repeat if needed. For continuous infusion: 0.5-2 mg/kg/hour calcium gluconate. Max rate: 1-2 m L/minute of 10% solution.
15 mg/kg/day IV divided every 8-12 hours or 15-20 mg/kg IV once daily; typical adult dose: 500-1000 mg IV every 8-12 hours.
Terminal elimination half-life is 6-8 hours in patients with normal renal function; prolonged in renal impairment (up to 24-48 hours).
The terminal elimination half-life is approximately 2-3 hours in adults with normal renal function. In neonates, it may be prolonged to 4-8 hours. In patients with impaired renal function, half-life can extend to 30-80 hours or more, necessitating dose adjustment based on creatinine clearance.
Not metabolized; calcium is excreted primarily in urine and feces.
Amikacin is minimally metabolized; primarily eliminated unchanged by glomerular filtration.
Primarily renal; ~80% of administered calcium is excreted in urine via glomerular filtration with tubular reabsorption; fecal excretion accounts for ~15-20% as unabsorbed or secreted calcium; negligible biliary excretion.
Amikacin is eliminated primarily by glomerular filtration. Approximately 94-98% of an administered dose is excreted unchanged in the urine within 24 hours in patients with normal renal function. Less than 1% is excreted in bile or feces.
Approximately 45-50% bound to albumin; also binds to globulins and other proteins.
Amikacin has low protein binding, ranging from 0-11%. It binds primarily to albumin, but due to low binding, protein binding alterations do not significantly impact pharmacokinetics.
0.15-0.25 L/kg; reflects distribution primarily in extracellular fluid; increases in conditions with increased capillary permeability.
The volume of distribution is approximately 0.25-0.4 L/kg in adults. It reflects distribution primarily into extracellular fluid. The Vd is increased in conditions such as edema, ascites, and sepsis, and is decreased in dehydration. In neonates, the Vd is larger (0.5-0.6 L/kg) due to higher extracellular fluid volume.
Intravenous: 100% (complete systemic availability); not administered orally for systemic effect due to poor bioavailability; calcium gluconate oral absorption is ~30% but not relevant for this formulation.
Intramuscular: Nearly complete, with bioavailability >90%. Oral: Not bioavailable due to negligible gastrointestinal absorption (<1%). Intravenous: 100%.
No specific dose reduction required; monitor serum calcium and phosphate levels. In severe renal impairment (Cr Cl <30 m L/min), use with caution due to risk of calcium loading and soft tissue calcification.
Cr Cl 30-60 m L/min: administer every 12-24 hours; Cr Cl 15-29 m L/min: administer every 24-48 hours; Cr Cl <15 m L/min: administer every 48-72 hours. Use therapeutic drug monitoring.
No dose adjustment required for hepatic impairment. Calcium gluconate is not hepatically metabolized.
No dosage adjustment required for hepatic impairment.
Neonates and infants: 200-500 mg/kg/day intravenously as a continuous infusion or in divided doses. Children: 500-1000 mg/kg/day intravenously; maximum single dose 1 g. Administer slowly (not exceeding 0.5-1 m L/min of 10% solution).
Neonates: 15-20 mg/kg IV every 24 hours; Infants and children: 15-20 mg/kg IV every 8-24 hours depending on age and renal function. Not to exceed 1.5 g/day.

Reduce initial dose based on renal function; monitor serum creatinine and drug levels; typical starting dose: 7.5 mg/kg IV every 24 hours adjusted for Cr Cl.
No FDA boxed warning.
Aminoglycosides, including amikacin, are associated with nephrotoxicity and ototoxicity (both auditory and vestibular), which can occur even at therapeutic doses. Risk is increased with prolonged use, higher doses, renal impairment, and concurrent use of other nephrotoxic or ototoxic drugs. Monitoring of renal function and serum drug levels is essential.
Risk of cardiac arrest or arrhythmia if administered too rapidly intravenously,Extravasation may cause tissue necrosis or sloughing,Use with caution in patients with renal impairment due to risk of hypercalcemia,May cause hypercalcemia; monitor calcium levels,Avoid in patients with digitalis toxicity due to risk of fatal arrhythmias
Neurotoxicity (including ototoxicity and nephrotoxicity) may occur. Risk of neuromuscular blockade, especially in patients with neuromuscular disorders or receiving anesthetics. Monitor renal function, audiometric tests, and serum drug concentrations. Use with caution in elderly, dehydrated, or renally impaired patients. Avoid concomitant use of other nephrotoxic or ototoxic agents.
Hypercalcemia,Severe hypercalciuria,Patients receiving digitalis (toxicity risk),Known hypersensitivity to calcium gluconate or any component of the formulation
Hypersensitivity to amikacin or any aminoglycoside; history of aminoglycoside-associated ototoxicity or nephrotoxicity; myasthenia gravis (risk of neuromuscular blockade).
No significant food interactions, but avoid excessive dietary calcium intake (e.g., dairy, fortified foods) during therapy to prevent hypercalcemia. Caffeine and alcohol may affect calcium levels; limit intake.
No significant food interactions. Maintain adequate hydration unless contraindicated. No specific dietary restrictions.
Calcium gluconate is a physiologic ion. No teratogenic effects are reported at therapeutic doses. Maternal calcium requirements increase during pregnancy, but exogenous calcium administration at standard doses is not associated with fetal malformations. However, maternal hypercalcemia (e.g., from excessive dosing) can lead to fetal hypoparathyroidism, hypotonia, and polyhydramnios, particularly in the third trimester.
Amikacin is an aminoglycoside antibiotic. There are no adequate and well-controlled studies in pregnant women. Aminoglycosides can cause fetal harm when administered to a pregnant woman. There is a potential for fetal ototoxicity and nephrotoxicity. First trimester: Risks unknown but avoid if possible. Second/Third trimester: Use only if clearly needed and if benefit outweighs risk; associated with irreversible bilateral congenital deafness when administered during pregnancy.
Calcium is a normal constituent of breast milk. Exogenous calcium gluconate administration increases maternal serum calcium transiently, but the effect on milk calcium concentration is minimal. The milk-to-plasma (M/P) ratio for calcium is approximately 0.1–0.3, indicating limited transfer. Use in breastfeeding mothers is considered compatible with breastfeeding when doses are within standard therapeutic ranges.
Amikacin is excreted in human milk in low concentrations. The M/P ratio is approximately 0.15-0.5. Based on limited data, the dose to the infant is estimated to be <1% of maternal dose. Use with caution in nursing mothers; monitor infant for diarrhea, candidiasis, and potential allergic reactions. Consider the benefits of breast-feeding and the importance of amikacin to the mother.
No dose adjustment required for standard calcium replacement or acute hypocalcemia treatment during pregnancy. However, due to increased calcium demand and altered renal handling (increased glomerular filtration rate), monitoring of serum calcium is recommended to avoid both hypo- and hypercalcemia. For IV administration in preeclampsia/eclampsia (as adjunct to magnesium sulfate), use standard non-pregnant dosing.
Pregnancy may alter pharmacokinetics due to increased volume of distribution and renal blood flow. However, specific dosing adjustments for amikacin in pregnancy are not well established. Monitor serum drug concentrations (peak and trough) to guide dosing, especially in patients with renal impairment or prolonged therapy. Use standard dosing with careful monitoring.
Calcium gluconate in sodium chloride (0.9% Na Cl) is used for intravenous calcium replacement. It provides 0.465 m Eq of calcium per m L (9.3 mg elemental calcium per m L). Infiltration causes severe tissue necrosis; use a central line if peripheral access is poor. Do not mix with bicarbonate, phosphate, or sulfate containing solutions (precipitates). Monitor ECG during infusion for bradycardia or arrhythmias. In cardiac arrest due to hyperkalemia or calcium channel blocker overdose, give 1 g IV push over 2-5 minutes with ECG monitoring. Extravasation: treat with hyaluronidase injection and warm compresses.
Avoid concomitant use with other nephrotoxic or ototoxic drugs (e.g., loop diuretics, vancomycin). Monitor peak (25-35 mcg/m L) and trough (<8 mcg/m L) serum levels to guide dosing and reduce toxicity risk. Extended-interval (once-daily) dosing is preferred in many patients; adjust for renal function using ideal body weight. In obese patients, dose based on adjusted body weight. Rapid infusion can cause neuromuscular blockade; use with caution in myasthenia gravis or concurrent neuromuscular blocking agents.

"Calcium gluconate provides exogenous calcium, which can counteract the calcium channel blocking effect of nimodipine. This reduces nimodipine's ability to inhibit calcium influx into vascular smooth muscle cells, potentially decreasing its antihypertensive and vasodilatory efficacy. Clinically, coadministration may lead to reduced nimodipine effectiveness in preventing cerebral vasospasm after subarachnoid hemorrhage."
"Sodium glycerophosphate, an organic phosphate source, can chelate calcium ions in the gastrointestinal tract, forming insoluble calcium phosphate complexes. This reduces the absorption of orally administered calcium gluconate, leading to lower serum calcium concentrations. Clinically, this may result in diminished efficacy of calcium supplementation, potentially exacerbating hypocalcemia in susceptible patients."
"Calcium gluconate chelates deferiprone in the gastrointestinal tract, forming a non-absorbable complex that reduces deferiprone's bioavailability. This results in decreased serum concentrations and diminished therapeutic efficacy of deferiprone, potentially leading to inadequate chelation of iron in patients with iron overload. Clinically, patients may experience suboptimal reduction of serum ferritin and increased risk of iron-related organ damage."
"Amikacin, an aminoglycoside antibiotic, may competitively inhibit the renal tubular secretion and potentially reduce the clearance of masoprocol, a dicarboxylic acid derivative used as a chemotherapeutic agent. This interaction could lead to increased systemic exposure to masoprocol, elevating the risk of dose-dependent toxicities such as severe enteritis, myelosuppression, and hepatotoxicity. Given the narrow therapeutic index of masoprocol, even modest elevations in serum levels may result in clinically significant adverse outcomes."
"Amikacin, an aminoglycoside antibiotic, may competitively inhibit the tubular secretion of mycophenolic acid (MPA) in the renal proximal tubules, leading to reduced renal clearance of MPA. This interaction can result in elevated serum levels of MPA, increasing the risk of dose-related toxicities such as bone marrow suppression (leukopenia, thrombocytopenia), gastrointestinal disturbances, and increased susceptibility to infections. Patients receiving this combination should be closely monitored for signs of MPA toxicity, especially those with pre-existing renal impairment."
"Coadministration of Metocurine, a nondepolarizing neuromuscular blocking agent, with Amikacin, an aminoglycoside antibiotic, may result in enhanced and prolonged neuromuscular blockade. Aminoglycosides can impair acetylcholine release from presynaptic nerve terminals and reduce postsynaptic sensitivity, synergistically augmenting the effects of nondepolarizing agents. This interaction can lead to excessive muscle relaxation, including respiratory muscle paralysis, increasing the risk of apnea and postoperative respiratory depression."
