Inulin is a polysaccharide that is not absorbed from the gastrointestinal tract and is used as a diagnostic agent to measure glomerular filtration rate (GFR) by renal clearance. Sodium chloride provides electrolyte supplementation.
Aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of m RNA and inhibition of protein synthesis.
Measurement of glomerular filtration rate (GFR),Diagnostic aid in renal function testing

Inulin: 5 g IV bolus followed by continuous infusion at 1.5 m L/min of a 10 g/L solution for GFR measurement. Sodium chloride: 0.9% solution as diluent.
15 mg/kg/day IV divided every 8-12 hours (usual adult dose: 15 mg/kg/day).
Normal renal function: 1.5 hours (range 1–2 h); decreases to 0.5 h with severe renal impairment; used to measure glomerular filtration rate (GFR)
Terminal elimination half-life: 2–3 hours in patients with normal renal function; may be prolonged to 30–60 hours in anuria.
Inulin is not metabolized; it is excreted unchanged by the kidneys. Sodium chloride is absorbed and distributed; no metabolism.
Primarily excreted unchanged by glomerular filtration. Minimal hepatic metabolism.
Renal: 100% as unchanged drug via glomerular filtration without tubular reabsorption or secretion; biliary/fecal: negligible (<1%)
Renal excretion of unchanged drug via glomerular filtration; >90% eliminated unchanged in urine within 24 hours. Biliary/fecal excretion <1%.
Approximately 0% (negligible); does not bind to plasma proteins
Low protein binding; 0–11% bound, primarily to albumin.
0.15–0.25 L/kg (approx. 15–25% of body weight; confined to extracellular fluid); reflects distribution limited to extracellular space
Vd: 0.25–0.4 L/kg; approximates extracellular fluid volume. Increased in edema, ascites; decreased in dehydration.
Intravenous: 100%; oral: <1% (not absorbed; used for oral GFR measurement but bioavailability is negligible)
Intravenous: 100% bioavailable. Not administered orally (negligible absorption).
Inulin excretion is renal; no dose adjustment as used for GFR measurement. In renal failure, monitor for hypernatremia from Na Cl content.
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 specific adjustment required; inulin is not hepatically metabolized.
No specific Child-Pugh based modifications; monitor renal function and drug levels.
Inulin: 0.5 m L/kg IV bolus of 10% solution followed by infusion at 0.15 m L/kg/min. Sodium chloride: as per isotonic requirement.
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 standard dosing; consider reduced GFR in elderly; monitor volume and electrolyte status.
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.
No FDA black box warning.
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 known anuria or severe renal impairment due to risk of accumulation. Monitor fluid and electrolyte balance.
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
Known hypersensitivity to inulin; anuria; severe renal impairment.
Hypersensitivity to amikacin or other aminoglycosides,Myasthenia gravis (relative due to risk of neuromuscular blockade)
No specific food interactions. Maintain adequate hydration as directed. Avoid excessive salt intake if sodium chloride load is a concern.
No clinically significant food interactions. Maintain adequate hydration. Avoid excessive alcohol consumption.
Inulin is not absorbed systemically; sodium chloride is physiologic. No known teratogenic risk in any trimester.
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.
Inulin is not absorbed systemically; sodium chloride is normal plasma constituent. M/P ratio not applicable. Considered safe during breastfeeding.
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 needed; pharmacokinetics of inulin and sodium chloride are not altered in pregnancy.
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.
Inulin is an inert polysaccharide used in glomerular filtration rate (GFR) measurement. Administer as a continuous IV infusion to maintain steady-state plasma levels. Avoid extravasation; inulin is non-irritating but high volumes may cause discomfort. Monitor for fluid overload in patients with compromised cardiac function due to sodium chloride content. Use isotonic (0.9%) or half-isotonic solution depending on hydration status.
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).
You will receive a solution containing inulin and salt through a vein to test your kidney function.,Report any pain, redness, or swelling at the IV site.,You may experience a metallic taste or warmth during infusion; these are temporary.,Stay well hydrated before and after the test unless advised otherwise.
Take exactly as prescribed; do not skip doses or stop early.,Drink plenty of fluids to stay hydrated.,Report hearing changes (ringing in ears, dizziness) immediately.,Report decreased urine output or swelling in legs.,Avoid taking other medications without consulting your doctor, especially pain relievers like ibuprofen.,This medication is given intravenously; you may feel warmth or tingling during infusion.
