Dextrose is a monosaccharide that provides a source of calories and may restore blood glucose levels. Sodium chloride and potassium chloride are electrolytes that maintain fluid and electrolyte balance.
Aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, causing misreading of m RNA and inhibiting bacterial protein synthesis.
FDA: Fluid and electrolyte replenishment, caloric supply in parenteral nutrition,Off-label: Prevention and treatment of dehydration, maintenance of fluid and electrolyte balance
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. Typical adult dose is 500-1000 m L as a continuous infusion at a rate dependent on fluid and electrolyte needs, usually 80-200 m L/hour.
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.
Dextrose: minutes (rapid cellular uptake). Sodium and chloride: half-life not applicable (regulated by renal function). Potassium: ~2-3 hours in normal renal function, prolonged in renal impairment. Clinical context: half-life of components reflects their distribution and elimination kinetics; potassium's half-life is most clinically relevant.
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.
Dextrose is metabolized via glycolysis and the Krebs cycle. Electrolytes are not metabolized but are excreted or reabsorbed by the kidneys.
Amikacin is minimally metabolized; primarily eliminated unchanged by glomerular filtration.
Dextrose is metabolized to CO2 and water; excretion is primarily renal (as water and electrolytes). Sodium and chloride are excreted renally (95%), with minimal fecal (<5%). Potassium is excreted renally (90%) and fecally (10%). The combination is fully eliminated via renal excretion of ions and water.
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.
Dextrose: negligible (<1%). Sodium, chloride: not protein-bound. Potassium: negligible (<1%)
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.
Dextrose: ~0.2 L/kg (related to extracellular fluid). Sodium and chloride: ~0.2 L/kg (extracellular). Potassium: ~0.4 L/kg (total body water, 98% intracellular). Clinical meaning: reflects distribution primarily into extracellular fluid for sodium/chloride/glucose; potassium distributes into total body water with high intracellular uptake.
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% (only route). Oral: not administered orally; enteral absorption of components would be complete but route not used for this combination.
Intramuscular: Nearly complete, with bioavailability >90%. Oral: Not bioavailable due to negligible gastrointestinal absorption (<1%). Intravenous: 100%.
Dose adjustments are primarily based on fluid and electrolyte status. In severe renal impairment (e GFR <30 m L/min/1.73 m²), use with caution due to risk of potassium accumulation; monitor serum potassium and consider reducing infusion rate or volume.
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 adjustments required for Child-Pugh class A, B, or C; however, monitor electrolytes in severe hepatic impairment due to risk of fluid and electrolyte imbalance.
No dosage adjustment required for hepatic impairment.
Weight-based dosing: 5-10 m L/kg/dose as a continuous infusion or as needed for maintenance, with rate adjusted to avoid fluid overload. Maximum infusion rate: 5-10 m L/kg/hour depending on age and clinical status.
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 decreased renal function and higher risk of fluid overload. Start at lower infusion rates (e.g., 50-100 m L/hour) and monitor serum electrolytes, renal function, and fluid status closely.
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.
Not for use in patients with anuria, hyperkalemia, hypernatremia, or conditions where administration of these electrolytes is contraindicated. Do not administer unless solution is clear and container is undamaged.
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 hyperglycemia and hyperosmolality in patients with glucose intolerance,Risk of fluid and/or solute overload with pulmonary edema or congestive heart failure,Monitor serum electrolytes, blood glucose, and fluid balance,Use with caution in patients with renal impairment, cardiac disease, or hyperkalemia
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.
Hyperkalemia,Hypernatremia,Anuria,Severe renal impairment,Acute myocardial infarction or pulmonary edema,Allergy to any component
Hypersensitivity to amikacin or any aminoglycoside; history of aminoglycoside-associated ototoxicity or nephrotoxicity; myasthenia gravis (risk of neuromuscular blockade).
Avoid high-potassium foods such as bananas, oranges, tomatoes, potatoes, and spinach during treatment to prevent hyperkalemia. Monitor dietary sodium intake. Dextrose may increase blood glucose; diabetic patients should follow their usual carbohydrate control measures.
No significant food interactions. Maintain adequate hydration unless contraindicated. No specific dietary restrictions.
Dextrose, sodium chloride, and potassium chloride are physiological components; no teratogenic risk has been associated with their use at standard replacement doses. No fetal harm is expected during any trimester when used as clinically indicated.
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.
Dextrose, sodium chloride, and potassium chloride are endogenous substances normally present in breast milk. Administration of this solution does not significantly alter milk composition; M/P ratio not applicable. 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 may increase fluid requirements and alter electrolyte needs. Dose adjustments may be necessary based on maternal weight, gestational age, and clinical status (e.g., hyperemesis, preeclampsia). Monitor serum electrolytes and glucose to guide 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.
Use with caution in patients with renal impairment due to potassium accumulation. Monitor serum potassium and glucose levels during prolonged administration. Avoid in patients with hyperkalemia, hypernatremia, or fluid overload. Do not administer simultaneously with blood products due to risk of hemolysis. Check for compatibility with concomitant IV medications; potassium may cause precipitation with certain drugs.
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."
