Intravenous infusion; dose and rate depend on patient's fluid and electrolyte status; typical maintenance: 0.9% Na Cl at 1-2 m L/kg/h.
15 mg/kg/day IV divided every 8-12 hours (usual adult dose: 15 mg/kg/day).
Terminal half-life is approximately 24-48 hours in healthy individuals, primarily reflecting renal sodium handling and total body sodium pool; significantly prolonged in renal impairment.
Terminal elimination half-life: 2–3 hours in patients with normal renal function; may be prolonged to 30–60 hours in anuria.
Sodium chloride is not metabolized; it is eliminated primarily by the kidneys.
Primarily excreted unchanged by glomerular filtration. Minimal hepatic metabolism.
Renal: >95% unchanged via glomerular filtration and tubular reabsorption. Fecal/biliary: negligible.
Renal excretion of unchanged drug via glomerular filtration; >90% eliminated unchanged in urine within 24 hours. Biliary/fecal excretion <1%.
None (0%). Sodium is a free ion and does not bind to plasma proteins.
Low protein binding; 0–11% bound, primarily to albumin.
Approximately 0.6-0.7 L/kg, representing total body water distribution; clinical meaning: reflects extracellular fluid volume expansion.
Vd: 0.25–0.4 L/kg; approximates extracellular fluid volume. Increased in edema, ascites; decreased in dehydration.
Oral: 100% (complete absorption); IV: 100%.
Intravenous: 100% bioavailable. Not administered orally (negligible absorption).
No specific dose adjustment; monitor serum sodium and fluid balance in impaired renal function (e GFR <30 m L/min/1.73 m²).
For GFR 30-59 m L/min: extend interval to every 12-24 hours; GFR 15-29 m L/min: every 24-48 hours; GFR <15 m L/min (not on dialysis): every 48-96 hours or consider dosing based on serum levels.
No adjustment required; use cautiously in cirrhosis with ascites.
No specific Child-Pugh based modifications; monitor renal function and drug levels.
Intravenous infusion; maintenance: 0.9% Na Cl at 100 m L/kg for first 10 kg, 50 m L/kg for next 10 kg, 20 m L/kg for each kg over 20 kg per 24 h.
Neonates: 15-20 mg/kg/day IV divided every 12 hours; Infants and Children: 15-22.5 mg/kg/day IV divided every 8-12 hours.
Use with caution due to increased risk of fluid overload; lower initial infusion rates recommended.
Adjust dose based on renal function; monitor serum creatinine and trough levels; usual starting dose: 15 mg/kg/day with extended intervals per renal function.
None.
Aminoglycosides can cause nephrotoxicity and ototoxicity. Neurotoxicity (including vestibular and auditory) may occur even at normal doses. Risk is greater in patients with renal impairment, pre-existing hearing loss, or prolonged use. Monitor renal function and eighth cranial nerve function.
Use with caution in patients with heart failure, renal impairment, edema, or hypertension.,Monitor serum electrolytes, fluid balance, and renal function during prolonged therapy.,Administration of large volumes may cause fluid overload, hypernatremia, or hypochloremia.,Avoid in patients with hypervolemic states or conditions causing sodium retention.
Monitor renal function and audiometric tests,Adjust dose based on renal function,Risk of neuromuscular blockade, especially in patients with neuromuscular disorders,Avoid concurrent use of other nephrotoxic or ototoxic drugs,Use caution in neonates, elderly, and patients with dehydration
Hypernatremia,Fluid overload,Severe renal impairment with oliguria or anuria,Hypersensitivity to sodium chloride
Hypersensitivity to amikacin or other aminoglycosides,Myasthenia gravis (relative due to risk of neuromuscular blockade)
No specific food interactions. However, patients should avoid excessive dietary sodium intake while receiving this medication to prevent hypernatremia. Monitor for changes in taste or nausea.
No clinically significant food interactions. Maintain adequate hydration. Avoid excessive alcohol consumption.
Sodium chloride administered intravenously at physiologic concentrations does not cross the placenta in significant amounts to cause fetal harm. No teratogenic effects are reported in any trimester. Hypertonic solutions may cause maternal electrolyte disturbances with potential secondary fetal effects if used inappropriately.
Aminoglycosides like amikacin cross the placenta. First trimester: No evidence of major malformations, but risk cannot be excluded. Second and third trimesters: Potential for fetal ototoxicity (eighth cranial nerve damage) and nephrotoxicity, especially with high doses or prolonged use. Avoid unless compelling indication.
Sodium chloride is a normal constituent of breast milk. Intravenous administration at usual doses does not significantly alter milk sodium concentration. M/P ratio is not applicable as sodium is endogenously regulated.
Minimal excretion into breast milk (M/P ratio unknown but expected low). No reports of adverse effects in nursing infants from maternal amikacin use. Caution with infant renal impairment or premature infants due to potential accumulation. Use only if necessary.
No dose adjustment required for normal physiologic use. In conditions with altered sodium handling (e.g., preeclampsia, hyperemesis gravidarum), individualize based on serum sodium and volume status. Pregnancy-induced plasma volume expansion does not necessitate dose changes for isotonic sodium chloride.
Increased renal clearance in pregnancy may lower serum levels; consider higher doses based on therapeutic drug monitoring. Adjust for renal impairment if present. Standard initial dosing: 15 mg/kg/day IV/IM divided q8-12h, with level-guided adjustments.
Monitor serum sodium and chloride levels closely in patients with heart failure, renal impairment, or liver cirrhosis to avoid hypernatremia or fluid overload. Use 0.9% sodium chloride (normal saline) as a first-line crystalloid for resuscitation; avoid 0.45% saline in patients at risk for increased intracranial pressure. The addition of dextrose may be indicated for hypoglycemia or to avoid hemolysis in hypotonic solutions.
Amikacin is an aminoglycoside antibiotic with concentration-dependent bactericidal activity. Monitor peak (20-30 mcg/m L) and trough (<10 mcg/m L) serum levels to optimize efficacy and minimize toxicity. Adjust dose based on renal function (Cr Cl). Ototoxicity (vestibular and cochlear) and nephrotoxicity are dose-limiting; audiometry and renal function tests are mandatory. Extended-interval dosing (15-20 mg/kg once daily) is preferred for most indications. Avoid concurrent use with other nephrotoxic drugs (e.g., vancomycin, loop diuretics).
