Dextrose is a monosaccharide that provides caloric support, replenishes glycogen stores, and prevents ketosis by supplying glucose for cellular energy metabolism. Sodium chloride maintains osmotic balance and replaces extracellular fluid and electrolytes.
Aminoglycoside antibiotic that irreversibly binds to the 30S ribosomal subunit, causing misreading of m RNA and inhibiting bacterial protein synthesis.
Fluid and electrolyte replacement,Treatment of dehydration,Intravenous infusion to provide calories and maintain blood glucose levels,Diluent for compatible medications
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; rate and volume determined by patient fluid and electrolyte needs, typically 1-2 L/day in adults.
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.
Exogenous dextrose has a plasma half-life of approximately 15–20 minutes under normal metabolic conditions; in hyperglycemia or insulin resistance, half-life is prolonged.
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 to produce carbon dioxide, water, and energy. Sodium and chloride ions are excreted primarily by the kidneys.
Amikacin is minimally metabolized; primarily eliminated unchanged by glomerular filtration.
Exogenous dextrose is fully metabolized to carbon dioxide and water; no significant renal or biliary excretion of intact dextrose. Sodium and chloride are primarily excreted renally (greater than 90% of filtered load reabsorbed; excess excreted in urine).
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 (<5%) protein binding. Sodium and chloride: not protein bound.
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: distributes into total body water, approximately 0.55–0.6 L/kg (in adults); sodium distributes primarily in extracellular fluid (0.2 L/kg).
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% bioavailable. Not administered via oral, intramuscular, or subcutaneous routes for caloric or fluid replacement (oral dextrose has high first-pass metabolism).
Intramuscular: Nearly complete, with bioavailability >90%. Oral: Not bioavailable due to negligible gastrointestinal absorption (<1%). Intravenous: 100%.
No specific dose adjustment required; monitor fluid and electrolyte balance in renal impairment. In severe renal failure (GFR <15 m L/min), reduce volume to avoid fluid overload.
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 required; monitor glucose and electrolytes in severe hepatic impairment due to risk of glucose intolerance.
No dosage adjustment required for hepatic impairment.
Intravenous infusion; dose based on weight and clinical condition. Typical maintenance: 4-8 mg/kg/min dextrose for neonates, 100-150 m L/kg/day for infants, adjusting for fluid and electrolyte needs.
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; reduced renal function may require lower infusion rates and smaller volumes to avoid fluid overload. Monitor serum glucose and electrolytes 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.
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 hyperglycemia, especially in patients with diabetes mellitus,Monitor serum electrolytes and fluid balance to avoid hypernatremia or fluid overload,Contraindicated in patients with hypertonic dehydration, hypernatremia, or hyperglycemia with ketosis,Use with caution in patients with congestive heart failure, renal failure, or liver cirrhosis,Large volumes may cause electrolyte disturbances or osmotic diuresis
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.
Hypertonic dehydration,Hypernatremia,Severe hyperglycemia with ketosis,Known hypersensitivity to dextrose or sodium chloride,Intracranial or intraspinal hemorrhage (if administered via cerebrospinal fluid routes)
Hypersensitivity to amikacin or any aminoglycoside; history of aminoglycoside-associated ototoxicity or nephrotoxicity; myasthenia gravis (risk of neuromuscular blockade).
No specific food interactions. However, concurrent administration of high-sugar or high-sodium foods may exacerbate hyperglycemia or hypernatremia. Monitor dietary intake of carbohydrates and sodium.
No significant food interactions. Maintain adequate hydration unless contraindicated. No specific dietary restrictions.
Dextrose 5% in 0.2% sodium chloride is a maintenance fluid; no teratogenic risk identified at standard doses. Maternal hyperglycemia from excessive dextrose may cause fetal hyperinsulinism and neonatal hypoglycemia, particularly in third trimester. Hypoosmolar states from improper administration could impair placental perfusion.
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 and sodium chloride are normal components of breast milk; no adverse effects expected at standard infusion rates. M/P ratio not applicable as endogenous substances.
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.
Dose adjustments not typically required. Monitor glucose closely and reduce infusion rate or switch to lower dextrose concentration if hyperglycemia develops. Increased plasma volume in pregnancy may necessitate higher total fluid volumes to maintain euvolemia, but sodium content should be considered to avoid edema.
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.
Monitor serum glucose and electrolytes during prolonged infusion. Administer via large peripheral or central vein to prevent phlebitis. Use with caution in patients with renal impairment, heart failure, or hyperglycemia. Do not administer if solution is discolored or contains particulates. Incompatible with blood products via same line.
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.

"Lithium cation may increase the excretion rate of Sodium chloride which could result in a lower serum level and potentially a reduction in efficacy."
"The risk or severity of adverse effects can be increased when Sodium chloride is combined with Tolvaptan."
"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."
