Anticoagulation in patients with heparin-induced thrombocytopenia (HIT) or heparin-induced thrombocytopenia and thrombosis (HITTS),Anticoagulation in patients with or at risk of HIT undergoing percutaneous coronary intervention (PCI)
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
Initial dose: 2 mcg/kg/min IV continuous infusion; maintenance: titrate to a PTT 1.5-3 times baseline, not to exceed 10 mcg/kg/min.
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.
Terminal elimination half-life: 39–51 minutes (mean ~45 min) following intravenous infusion. In hepatic impairment, half-life is prolonged up to 3-fold. Short half-life allows rapid offset of anticoagulation if needed.
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.
Primarily hepatic via CYP3A4/5; metabolites (unchanged, hydroxylated, and carboxylated) are excreted mainly in bile.
Amikacin is minimally metabolized; primarily eliminated unchanged by glomerular filtration.
Primarily hepatic (biliary/fecal); approximately 65% excreted in feces and 22% in urine (unchanged drug minimal). Renal elimination accounts for 16% as unchanged drug. Dosage adjustment required for hepatic impairment; not significantly affected by renal impairment.
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.
54% bound to human serum albumin and alpha-1-acid glycoprotein.
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.
Volume of distribution: 0.2–0.4 L/kg (approx. 174 m L/kg). Indicates distribution primarily in extracellular fluid.
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 an IV infusion only; not available for other routes).
Intramuscular: Nearly complete, with bioavailability >90%. Oral: Not bioavailable due to negligible gastrointestinal absorption (<1%). Intravenous: 100%.
No dose adjustment required for renal impairment; caution in dialysis patients as drug is removed by 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.
For Child-Pugh class A, B, or C: initial dose 0.5 mcg/kg/min IV continuous infusion with frequent a PTT monitoring.
No dosage adjustment required for hepatic impairment.
Safety and effectiveness not established; limited data: initial dose 0.75 mcg/kg/min IV; titrate to a PTT 1.5-3 times baseline, max 2 mcg/kg/min.
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; increased risk of bleeding due to age-related changes; monitor a PTT closely and use lower initial doses if frail.
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.
WARNING: Risk of bleeding. Argatroban can cause major bleeding, including intracranial hemorrhage, especially in patients with hepatic impairment or other risk factors for bleeding. Monitor for signs of bleeding and adjust dose accordingly.
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.
Bleeding risk: Increased risk of hemorrhage, especially in patients with hepatic dysfunction, severe hypertension, or concomitant antithrombotic therapy,Hepatic impairment: Dose reduction required; may lead to prolonged anticoagulation,Renal impairment: Caution in severe renal impairment; no dose adjustment recommended but monitoring advised,Pregnancy: Limited data, use only if clearly needed,Lactation: Not recommended,Pediatric use: Safety and efficacy not established,Elderly: Increased sensitivity; monitor closely
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.
Active major bleeding,Hypersensitivity to argatroban or any component,Severe hepatic impairment (Child-Pugh class C) unless used in HIT with life-threatening thrombosis
Hypersensitivity to amikacin or any aminoglycoside; history of aminoglycoside-associated ototoxicity or nephrotoxicity; myasthenia gravis (risk of neuromuscular blockade).
No specific food interactions. Maintain consistent intake of vitamin K-rich foods if on warfarin transition.
No significant food interactions. Maintain adequate hydration unless contraindicated. No specific dietary restrictions.
Pregnancy Category B. Animal studies show no evidence of fetal harm; no adequate human studies. Use only if clearly needed. First trimester: no known risk. Second trimester: no known risk. Third trimester: increased risk of maternal hemorrhage; fetal risk minimal.
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.
No data on excretion in human milk; present in rat milk. M/P ratio unknown. Caution advised; discontinue breastfeeding or drug based on importance.
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 specific pregnancy dose adjustments; use with caution due to altered hemodynamics and renal function. Titrate a PTT carefully.
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.
Argatroban is a direct thrombin inhibitor used for heparin-induced thrombocytopenia (HIT). Monitor a PTT closely, targeting 1.5-3 times baseline. Dose adjustment required in hepatic impairment. Do not use intramuscularly due to bleeding risk. Antidote not available; half-life ~50 minutes.
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.

"Deferasirox, an oral iron chelator, reduces the serum concentration of argatroban, a direct thrombin inhibitor, likely through induction of hepatic metabolism. This interaction may lead to subtherapeutic anticoagulation, increasing the risk of thrombotic events such as deep vein thrombosis or pulmonary embolism. Clinicians should monitor anticoagulant effect closely and adjust argatroban dose accordingly."
"Hydroxyprogesterone caproate, a progestogen used to reduce preterm birth risk, may induce hepatic CYP450 enzymes, potentially increasing the clearance of argatroban, a direct thrombin inhibitor. This interaction could reduce argatroban's anticoagulant effect, increasing the risk of thromboembolic events in patients requiring anticoagulation. Clinical outcomes may include subtherapeutic anticoagulation and failure to prevent or treat thrombosis."
"Gestodene, a progestin component of combined oral contraceptives, induces hepatic CYP450 enzymes, including CYP3A4 and CYP2C9, which are responsible for the metabolism of argatroban, a direct thrombin inhibitor. This induction accelerates argatroban clearance, reducing its plasma concentration and anticoagulant effect, potentially leading to subtherapeutic anticoagulation and increased risk of thromboembolic events. Clinically, this interaction may result in decreased efficacy of argatroban during concurrent use with gestodene-containing contraceptives."
"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."
