FDA: Potassium replacement in hypokalemia; caloric provision; fluid and electrolyte replenishment.,Off-label: Prevention of hypokalemia in patients receiving diuretics; management of metabolic alkalosis.
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
Intravenous infusion. The rate and volume depend on the patient's fluid and electrolyte needs. Typical adult dose: 1000 m L to 2000 m L per 24 hours, providing 30-60 m Eq potassium, 154 m Eq sodium, 100 g dextrose, and 154 m Eq chloride daily. Infusion rate not to exceed 10 m Eq/hour of potassium; maximum 20 m Eq/hour with continuous cardiac monitoring.
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.
Potassium: ~12 h (non-steady-state); chloride: ~8-12 h; glucose: 1.5-2.5 h. Half-life prolonged with renal impairment or hyperkalemic states.
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.
Potassium is primarily excreted unchanged by the kidneys; minor gastrointestinal loss. Dextrose is metabolized via glycolysis to pyruvate, then enters the TCA cycle. Sodium chloride dissociates into ions and is renally regulated.
Amikacin is minimally metabolized; primarily eliminated unchanged by glomerular filtration.
Renal: >90% as potassium, chloride, and glucose; lesser extent fecal/ biliary. Potassium and chloride are actively reabsorbed; glucose is completely reabsorbed (up to ~180 mg/d L) from glomerular filtrate.
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.
Potassium: negligible (<2%); chloride: minimal; glucose: negligible (<10% in normoglycemic states). No specific binding 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.
Potassium: ~0.5 L/kg (total body water); glucose: ~0.2 L/kg (extracellular fluid); chloride: ~0.3 L/kg. Vd increased in hypokalemic states.
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.
IV: 100% for all components. Oral not applicable; parenteral route only.
Intramuscular: Nearly complete, with bioavailability >90%. Oral: Not bioavailable due to negligible gastrointestinal absorption (<1%). Intravenous: 100%.
Contraindicated in severe renal impairment (GFR <30 m L/min). For moderate impairment (GFR 30-50 m L/min), reduce potassium content; avoid use or use with extreme caution. Monitor serum potassium and renal function closely.
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 specific dose adjustment for hepatic impairment. Use with caution in severe hepatic disease due to potential fluid and electrolyte abnormalities. Monitor electrolytes and glucose.
No dosage adjustment required for hepatic impairment.
Weight-based dosing: 0.15% potassium chloride in 10% dextrose and 0.9% sodium chloride. Typical rate: 2-4 m L/kg/hour, providing potassium at 0.03-0.06 m Eq/kg/hour, dextrose at 0.2-0.4 g/kg/hour, and sodium at 0.18-0.36 m Eq/kg/hour. Adjust based on serum electrolytes and glucose; do not exceed maximum potassium infusion rate of 0.5 m Eq/kg/hour.
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.
Use with caution due to age-related decline in renal function. Initiate at low end of dosing range; monitor renal function, serum potassium, and fluid status to avoid hyperkalemia, fluid overload, and glucose intolerance. Adjust rate based on comorbidities and concurrent medications.
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.
Concentrated potassium solutions (not this product) require dilution and careful administration to avoid fatal hyperkalemia and cardiac arrest. This specific formulation is premixed and risk is lower but still monitor serum potassium.
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.
Monitor serum potassium, glucose, and electrolytes; risk of hyperkalemia in renal impairment; risk of hyperglycemia in diabetes mellitus; fluid overload in heart failure or renal failure; do not administer if solution is cloudy or contains particulates.
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.
Absolute: Hyperkalemia; hyperglycemia; hypernatremia; severe renal impairment with oliguria; anuria; patients with increased potassium sensitivity (e.g., Addison's disease). Relative: cardiac disease; concurrent use of potassium-sparing diuretics.
Hypersensitivity to amikacin or any aminoglycoside; history of aminoglycoside-associated ototoxicity or nephrotoxicity; myasthenia gravis (risk of neuromuscular blockade).
No specific food interactions. Patients should avoid excessive potassium-rich foods (e.g., bananas, oranges, potatoes) if hyperkalemia risk, but this is typically managed by monitoring and dose adjustments. No restrictions on alcohol or grapefruit.
No significant food interactions. Maintain adequate hydration unless contraindicated. No specific dietary restrictions.
Potassium chloride (KCl) is an essential electrolyte; no teratogenic risk is anticipated when administered at therapeutic doses. Dextrose at 10% and sodium chloride at 0.9% are also considered low risk. However, maternal electrolyte imbalances (e.g., hyperkalemia, hypoglycemia) may indirectly affect fetal development. No specific trimester-associated risks have been identified.
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.
Potassium chloride and sodium chloride are normal constituents of breast milk. Dextrose is metabolized to glucose, which is regulated endogenously. Exogenous administration does not significantly increase milk levels. The M/P ratio is not applicable as these are endogenous substances. This solution is considered compatible with breastfeeding.
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.
Pregnancy increases plasma volume and GFR, potentially altering electrolyte requirements. However, KCl 0.15% in D10% and Na Cl 0.9% provides fixed concentrations; dose adjustments are based on maternal electrolyte status and fluid needs, not gestational age. Monitor electrolytes and adjust infusion rate accordingly; no blanket dose alteration is recommended.
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.
This IV solution is used for maintenance or replacement of fluid, electrolytes, and calories. Monitor serum potassium and glucose levels, especially in patients with renal impairment or diabetes. Infuse via central line if concentration exceeds peripheral vein tolerance; peripheral administration may cause phlebitis. Rapid infusion can cause hyperkalemia and cardiac arrhythmias. Use with caution in patients with heart failure or hypervolemia.
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.

"Atracurium besylate, a nondepolarizing neuromuscular blocking agent, may enhance the ulcerogenic potential of oral potassium chloride by reducing gastrointestinal motility and increasing local contact time of the potassium chloride tablet with the gastric and intestinal mucosa. This prolonged exposure can heighten the risk of gastrointestinal erosion, bleeding, or perforation, particularly in patients with pre-existing lesions or receiving high-dose potassium supplementation. Clinically, this interaction necessitates close monitoring for signs of gastrointestinal injury when these agents are coadministered."
"Methscopolamine bromide, an anticholinergic agent, reduces gastrointestinal motility and delays gastric emptying, which can prolong the contact time of orally administered Potassium chloride (KCl) tablets or capsules with the gastric mucosa. This increased exposure to high concentrations of potassium in the gastrointestinal tract potentiates the local ulcerogenic effect of KCl, leading to a higher risk of esophageal, gastric, or intestinal erosions, ulcers, hemorrhage, perforation, or stricture formation. Clinically, this interaction may present with dysphagia, epigastric pain, hematemesis, melena, or signs of acute abdomen."
"Fesoterodine, an anticholinergic agent used for overactive bladder, can reduce gastric motility and prolong gastrointestinal transit time. This effect may increase the local contact time of potassium chloride tablets with the gastrointestinal mucosa, potentiating the ulcerogenic risk of potassium chloride, which can cause esophageal or intestinal ulceration, stenosis, or perforation. The interaction is clinically significant in patients with pre-existing gastrointestinal motility disorders or those taking high-dose potassium supplements."
"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."
