40 mg intravenously over 2-15 minutes once daily for up to 10 days.
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.
Approximately 1 hour (range 0.5–2 hours) in healthy adults; prolonged in hepatic impairment (up to 3–6 hours) and CYP2C19 poor metabolizers.
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.
Hepatic metabolism via CYP2C19 (major) and CYP3A4 (minor); metabolites include inactive desmethylpantoprazole and sulfone conjugates.
Amikacin is minimally metabolized; primarily eliminated unchanged by glomerular filtration.
Renal: approximately 80% as metabolites and unchanged drug; fecal: approximately 20% as metabolites.
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.
Approximately 98% bound to albumin.
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.
Approximately 0.15–0.26 L/kg, indicating limited extravascular distribution.
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% (administered as infusion over 15 minutes); oral bioavailability is approximately 77% but this monograph pertains to IV formulation.
Intramuscular: Nearly complete, with bioavailability >90%. Oral: Not bioavailable due to negligible gastrointestinal absorption (<1%). Intravenous: 100%.
No dose adjustment required for renal impairment, including hemodialysis.
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.
In Child-Pugh Class A: no adjustment. In Child-Pugh Class B and C: maximum daily dose of 20 mg intravenously.
No dosage adjustment required for hepatic impairment.
For children ≥5 years: 15 kg to <40 kg: 20 mg once daily; ≥40 kg: 40 mg once daily. For children <5 years: safety and efficacy not established.
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.
No specific dose adjustment, but monitor for potential increased risk of adverse effects such as Clostridioides difficile infection and osteoporosis-related fractures.
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.
None reported.
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.
Prolonged use may increase risk of Clostridium difficile-associated diarrhea,Increased risk of osteoporosis-related fractures with long-term high-dose use,Hypomagnesemia reported with long-term use,Acute interstitial nephritis,May mask symptoms of gastric malignancy,Coadministration with methotrexate may increase methotrexate toxicity,Possible reduced absorption of vitamin B12 with long-term use
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.
Known hypersensitivity to pantoprazole or other proton pump inhibitors,Coadministration with rilpivirine,Coadministration with atazanavir (due to reduced absorption)
Hypersensitivity to amikacin or any aminoglycoside; history of aminoglycoside-associated ototoxicity or nephrotoxicity; myasthenia gravis (risk of neuromuscular blockade).
No significant food interactions with IV pantoprazole. However, if transitioning to oral therapy, advise taking oral pantoprazole at least 30 minutes before meals for maximal effect. Avoid alcohol as it can exacerbate gastric irritation and delay healing.
No significant food interactions. Maintain adequate hydration unless contraindicated. No specific dietary restrictions.
FDA Pregnancy Category B. No evidence of teratogenicity in animal studies. First trimester: limited human data, no increased risk of major malformations. Second/third trimester: no known fetal risks. Risk of maternal hypomagnesemia with prolonged use may affect fetal bone development.
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.
Unknown if excreted in human milk; M/P ratio not available. Caution advised; consider risk of infant acid suppression. Preferred alternatives may include PPIs with more lactation data.
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.
No dose adjustment required. Pharmacokinetics of pantoprazole unchanged in pregnancy; standard dose (40 mg IV daily) 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.
Pantoprazole sodium in 0.9% sodium chloride is a proton pump inhibitor (PPI) for IV administration. Administer via IV infusion over 15-30 minutes; do not mix with other medications or IV solutions. Compatible with Y-site administration with selected drugs (e.g., cefepime, levofloxacin) per compatibility charts. Monitor for injection-site reactions, thrombophlebitis, and rare but serious side effects like acute interstitial nephritis, Clostridioides difficile infection, and hypomagnesemia with prolonged use. For stress ulcer prophylaxis in critically ill patients, IV pantoprazole is preferred over oral due to absorption concerns. Contraindicated in patients with known hypersensitivity to PPIs or substituted benzimidazoles. Dose adjustment not required in renal impairment but caution in hepatic impairment (max dose 40 mg/day in severe disease). Do not use for immediate symptom relief in acute dyspepsia as onset of action is delayed.
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.

"Pantoprazole, a proton pump inhibitor, inhibits CYP1A2 and CYP2D6 isoenzymes, which are involved in the metabolism of ropinirole. This can lead to decreased clearance of ropinirole, resulting in elevated plasma concentrations and increased risk of dose-related adverse effects such as hypotension, somnolence, and dyskinesias. Clinically, patients may experience exacerbated side effects of ropinirole, particularly at higher doses or in those with renal impairment."
"The combination of afatinib, a tyrosine kinase inhibitor, with pantoprazole, a proton pump inhibitor (PPI), can lead to reduced absorption of afatinib due to elevated gastric pH. Afatinib exhibits pH-dependent solubility, and higher gastric pH decreases its dissolution and bioavailability, potentially reducing its therapeutic efficacy. This interaction may result in suboptimal plasma concentrations of afatinib, increasing the risk of treatment failure in patients with non-small cell lung cancer."
"Pantoprazole, a proton pump inhibitor, may reduce the gastric pH-dependent absorption of isavuconazonium, an azole antifungal prodrug that requires hydrolysis in an acidic environment for conversion to its active moiety, isavuconazole. Additionally, pantoprazole is an inhibitor of CYP2C19, a hepatic enzyme involved in the metabolism of isavuconazole, potentially increasing isavuconazole plasma concentrations. This dual mechanism can lead to reduced antifungal efficacy due to decreased absorption and increased risk of toxicity from elevated isavuconazole levels, including hepatotoxicity and QTc prolongation."
"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."
