Treatment of hypocalcemia,Calcium supplementation in patients requiring parenteral calcium,Treatment of hypermagnesemia,Cardiac resuscitation (as an adjunct),Treatment of calcium channel blocker overdose
Oral: 20 m Eq (2 tablets) 2-4 times daily with meals; maximum 100 m Eq/day.
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.
Terminal elimination half-life is approximately 3-5 hours in healthy adults, reflecting rapid equilibration with the total body potassium pool. Clinically, the half-life is not directly applicable due to extensive intracellular distribution; steady-state is achieved within 24-48 hours.
Terminal elimination half-life: 2-4 hours (normal renal function); prolonged to 12-24 hours in renal impairment.
Potassium is primarily excreted unchanged by the kidneys; metabolism is not significant.
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.
Primarily renal elimination (>90% as unchanged drug); minor biliary/fecal excretion (<5%). Excretion is via glomerular filtration and tubular reabsorption; potassium excretion is influenced by aldosterone and acid-base status.
Renal: >90% excreted unchanged in urine. Biliary/fecal: <5%.
Potassium is not significantly protein-bound; <5% bound to plasma proteins.
~45% bound to albumin.
Approximately 0.5 L/kg, representing distribution primarily into intracellular fluid (98% of total body potassium is intracellular). Clinical meaning: Low Vd indicates limited distribution to extracellular space; high intracellular uptake requires careful dosing to avoid hyperkalemia.
0.15-0.25 L/kg; represents distribution mainly in extracellular fluid.
Oral: >90% absorbed via passive diffusion along the gastrointestinal tract. Intravenous: 100% bioavailability.
IV: 100%; IM: not well characterized; oral: negligible (absorbed poorly, systemic bioavailability <1% as calcium gluceptate dissociates in GI tract).
GFR 30-50 m L/min: reduce dose by 25%; GFR 10-29 m L/min: reduce dose by 50%; GFR <10 m L/min: avoid use.
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.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 25%; Child-Pugh C: avoid use.
No dose adjustment required for hepatic impairment. However, monitor ionized calcium in severe hepatic failure due to altered binding proteins.
Oral: 1-3 m Eq/kg/day in divided doses, maximum 3 m Eq/kg/day; not recommended for children <1 year.
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.
Start at lowest dose (10 m Eq twice daily); monitor renal function and potassium levels; avoid doses exceeding 40 m Eq/day.
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.
Warning: Potassium chloride can cause hyperkalemia and cardiac arrest if given too rapidly or in excessive doses. Avoid in patients with severe renal impairment, adrenal insufficiency, or concurrent use of potassium-sparing diuretics.
No FDA black box warning.
Monitor serum potassium levels and renal function; avoid high doses or rapid infusion; use with caution in patients with cardiac disease or receiving digitalis; gastrointestinal irritation may occur with oral preparations.
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
Severe renal impairment (e.g., anuria, oliguria), untreated Addison's disease, hyperkalemia from any cause, acute dehydration, heat cramps, concurrent use of potassium-sparing diuretics (e.g., amiloride, spironolactone), hypersensitivity to potassium chloride.
Hypercalcemia,Hypersensitivity to calcium gluceptate or any component,Ventricular fibrillation,Patients with known calcium-containing calculi
Avoid salt substitutes and low-sodium products that contain potassium chloride. No specific food restrictions beyond ensuring adequate water intake with each dose to prevent esophageal or gastric irritation.
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.
Potassium chloride (the active ingredient in Kaon CL-10) is not associated with teratogenic risk in any trimester. No fetal malformations or developmental toxicity have been reported. Hypokalemia itself may pose maternal and fetal risks, but the drug does not have intrinsic teratogenic potential.
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.
Potassium chloride is a normal constituent of breast milk. M/P ratio not applicable as potassium is present endogenously. Supplementation to correct maternal hypokalemia is considered safe during breastfeeding, as potassium levels in milk are tightly regulated and maternal supplementation does not significantly alter infant potassium levels.
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 dose adjustment required for pregnancy. Maternal potassium requirements may increase slightly due to increased plasma volume and renal blood flow, but hypokalemia should be corrected per standard guidelines. Monitor serum potassium to avoid hyperkalemia.
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.
Kaon CL-10 is a solid oral dosage form of potassium chloride (KCl) 10 m Eq. Do not split or crush tablets; they must be swallowed whole with a full glass of water to reduce GI irritation. Monitor serum potassium, renal function, and ECG. Use with caution in patients with impaired renal function or those on ACE inhibitors, ARBs, or potassium-sparing diuretics. Rapid IV correction is reserved for severe hypokalemia with ECG changes.
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.
