Treatment of hypokalemia,Prevention of hypokalemia in patients receiving diuretics or other drugs that deplete potassium
Treatment of hypokalemia,Prevention of hypokalemia in patients receiving digitalis and diuretics,Off-label: prevention of hypokalemia in patients on potassium-wasting diuretics
Oral: 20 m Eq (2 tablets) 2-4 times daily with meals; maximum 100 m Eq/day.
Oral: 20 m Eq (one tablet) two to four times daily with meals and a full glass of water; maximum 100 m Eq/day. Slow-release tablet should not be crushed or chewed. Intravenous: not applicable for KAON CL (oral formulation).
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 half-life is approximately 0.5–1.5 hours in healthy individuals; prolonged in renal impairment (up to 6–12 hours in end-stage renal disease).
Potassium is primarily excreted unchanged by the kidneys; metabolism is not significant.
Not significantly metabolized; primarily excreted unchanged by the kidneys, with minor fecal elimination.
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.
Primarily renal: >90% excreted unchanged in urine; minimal biliary/fecal elimination (<5%).
Potassium is not significantly protein-bound; <5% bound to plasma proteins.
Minimal protein binding (<1%); not significantly bound to plasma proteins.
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.
Approximately 0.5–0.8 L/kg; distributes mainly in extracellular fluid, with minimal intracellular penetration.
Oral: >90% absorbed via passive diffusion along the gastrointestinal tract. Intravenous: 100% bioavailability.
Oral bioavailability is ~90-100% due to complete absorption of potassium chloride; food may slightly reduce absorption but overall high.
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 m L/min: no adjustment; GFR 10-50 m L/min: use with caution, reduce dose and monitor serum potassium; GFR < 10 m L/min: contraindicated due to risk of hyperkalemia.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 25%; Child-Pugh C: avoid use.
No specific adjustment for Child-Pugh class A or B; use with caution in severe hepatic impairment (Child-Pugh C) due to increased risk of hyperkalemia from potential electrolyte disturbances.
Oral: 1-3 m Eq/kg/day in divided doses, maximum 3 m Eq/kg/day; not recommended for children <1 year.
Dose determined by physician based on serum potassium levels and underlying condition; typical oral dose: 1-3 m Eq/kg/day in divided doses, not to exceed 1 m Eq/kg per single dose or maximum 4 m Eq/kg/day. Extended-release tablets not recommended for children < 12 years unless specifically directed.
Start at lowest dose (10 m Eq twice daily); monitor renal function and potassium levels; avoid doses exceeding 40 m Eq/day.
Elderly patients often have reduced renal function and may require lower starting doses (e.g., 20 m Eq twice daily) with close monitoring of serum potassium and renal function. Avoid if e GFR < 30 m L/min/1.73 m².
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.
Potassium chloride can cause hyperkalemia and cardiac arrest if administered too rapidly or in excessive doses. Avoid use in patients with severe renal impairment or conditions that predispose to hyperkalemia.
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.
Hyperkalemia risk, especially in renal impairment,Avoid solid oral forms in patients with esophageal stricture or delayed GI transit,May exacerbate metabolic alkalosis,Monitor serum potassium levels regularly
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.
Hyperkalemia,Severe renal impairment (oliguria, anuria, or azotemia),Concurrent use of potassium-sparing diuretics or ACE inhibitors (with caution),Untreated Addison's disease,Acute dehydration or heat cramps
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 excessive intake of potassium-rich foods (e.g., bananas, oranges, spinach, potatoes) and salt substitutes containing potassium, as they may increase risk of hyperkalemia. Taking with food reduces gastrointestinal irritation.
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.
Potassium chloride is not associated with teratogenicity. No increased risk of major birth defects in any trimester.
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.
Potassium is a normal component of breast milk. Exogenous potassium does not significantly alter milk levels. M/P ratio not established; considered compatible with breastfeeding.
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 dose adjustment required for potassium chloride in pregnancy; pharmacokinetics are substantially unchanged.
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.
KAON CL is a potassium chloride supplement. Monitor serum potassium levels frequently, especially in patients with renal impairment or those on ACE inhibitors/ARBs, NSAIDs, or potassium-sparing diuretics to avoid hyperkalemia. Administer with food to minimize gastrointestinal irritation. Do not crush or chew extended-release formulations; swallow whole. Hypomagnesemia can cause refractory hypokalemia; check magnesium levels if potassium repletion fails.
