400 mg intravenously once daily. Infuse over 60 minutes.
Intravenous infusion; dosing based on patient's fluid and electrolyte needs. Typical adult dose: 500-1000 m L per hour as needed for volume replacement; adjust rate based on clinical response and serum electrolyte monitoring.
Terminal elimination half-life of moxifloxacin is approximately 11-15 hours in patients with normal renal function; allows once-daily dosing.
Not applicable as a fixed half-life; components distribute and equilibrate rapidly. For administered volume, intravascular half-life is 20-30 minutes due to redistribution to interstitial space. Electrolyte half-lives: sodium ~8-12 hours, chloride ~8-12 hours, potassium ~12-24 hours, calcium ~24-48 hours, magnesium ~24-48 hours.
Hepatic via glucuronide and sulfate conjugation; CYP450 system not significantly involved.
Acetate is metabolized via acetyl-Co A in the tricarboxylic acid cycle, yielding bicarbonate; primary sites include liver and skeletal muscle.
Renal (approximately 45-60% as unchanged drug and metabolites); biliary/fecal (approximately 20-25% as unchanged drug and metabolites); total urinary and fecal recovery >95%.
Acetated Ringer's solution components are excreted primarily renally: water (100% via kidneys), sodium (90-95% renal, 5-10% sweat/feces), chloride (90-95% renal), acetate (metabolized to bicarbonate, then CO2 excreted via lungs; <5% renal), potassium (80-90% renal, 10-20% feces), calcium (98% renal reabsorption, <2% fecal), magnesium (70% renal, 30% fecal).
Approximately 40-50% bound to serum proteins, primarily albumin.
Calcium: ~40% bound to albumin; magnesium: ~30% bound to albumin; other components (sodium, potassium, chloride, acetate) have negligible protein binding (<5%).
Volume of distribution is approximately 2.8 L/kg; indicates extensive tissue penetration, including into lungs, sinuses, skin, and soft tissues.
Not a single value for all components. Water distributes into total body water (0.6 L/kg), sodium and chloride primarily into extracellular fluid (0.2 L/kg), potassium into intracellular fluid (0.4 L/kg), calcium and magnesium into bone and cells (Vd ~0.5-0.8 L/kg).
Intravenous: 100% (complete immediate bioavailability).
Intravenous: 100% (only route administered). Oral: not applicable; not administered orally.
For GFR <30 m L/min, reduce dose to 400 mg intravenously every 48 hours.
No specific GFR-based dose adjustment required; however, use with caution in renal impairment due to risk of fluid overload and electrolyte imbalances. Monitor serum potassium and renal function.
No dosage adjustment required for mild to moderate hepatic impairment (Child-Pugh A or B). Not studied in severe hepatic impairment (Child-Pugh C).
No specific Child-Pugh dose adjustment; use with caution in severe hepatic impairment due to potential altered lactate metabolism. Monitor electrolytes and acid-base status.
Safety and efficacy not established in pediatric patients under 18 years.
Weight-based dosing: 20-30 m L/kg as a bolus over 30-60 minutes for volume expansion; maintenance: adjust based on fluid deficit and ongoing losses. Maximum rate and volume vary by clinical condition.
No routine dosage adjustment required based on age alone; monitor renal function and adjust as per renal impairment guidelines.
Consider reduced initial volume and slower infusion rate due to decreased cardiovascular reserve and higher risk of fluid overload. Monitor closely for signs of heart failure and electrolyte disturbances.
Fluoroquinolones, including moxifloxacin, have been associated with an increased risk of tendinitis and tendon rupture in all ages. This risk is further increased in patients older than 60 years, those taking corticosteroids, and those with kidney, heart, or lung transplants. Fluoroquinolones may exacerbate muscle weakness in persons with myasthenia gravis. Avoid use in patients with known history of myasthenia gravis.
Not available; no FDA boxed warning.
May prolong QT interval; avoid in patients with known QTc prolongation, uncorrected hypokalemia, or receiving class IA or III antiarrhythmics. Use with caution in patients with CNS disorders (e.g., epilepsy). Discontinue if signs of tendon pain, inflammation, or rupture occur. May cause peripheral neuropathy. Use with caution in patients with renal impairment. Avoid in patients with known hypersensitivity to fluoroquinolones.
Monitor serum electrolytes and acid-base status; avoid in patients with severe renal impairment or alkalosis; caution in heart failure, pulmonary edema, and conditions causing sodium retention.
Hypersensitivity to moxifloxacin or any fluoroquinolone; history of tendinopathy with fluoroquinolones; patients with myasthenia gravis; pregnancy (category C); nursing mothers; children <18 years; patients with known QTc prolongation or uncorrected electrolyte disturbances.
Hypernatremia, hyperkalemia, hypercalcemia, metabolic alkalosis, severe renal failure with oliguria/anuria, and known hypersensitivity to any component.
No specific food interactions. However, avoid alcohol as it may increase risk of dizziness and gastrointestinal side effects. Keep well hydrated.
No specific food interactions. However, dietary intake of sodium and potassium should be considered in patients with electrolyte imbalances or renal impairment.
Fluoroquinolones, including moxifloxacin, are associated with an increased risk of arthropathy in juvenile animals. In humans, data from pregnant women exposed to fluoroquinolones are limited. First trimester exposure is not associated with major malformations; however, second and third trimester exposure may be linked to fetal bone and cartilage damage. Use during pregnancy should be reserved for infections where no alternatives exist.
No fetal risks identified; acetated Ringer's solution is isotonic and used for fluid and electrolyte replenishment. No teratogenic effects reported in any trimester.
Moxifloxacin is excreted into human milk at very low concentrations. The M/P ratio is approximately 0.68. The estimated infant dose is less than 1% of the maternal dose. Caution is advised due to potential for infant joint damage, but no adverse effects reported. Consider interruption of breastfeeding during therapy and for 48 hours after last dose.
Considered safe during breastfeeding; components (sodium, chloride, potassium, calcium, acetate) are normal physiological constituents. M/P ratio not applicable.
Pregnancy-induced physiological changes (increased volume of distribution, enhanced renal clearance) may lower moxifloxacin plasma concentrations. However, no specific dose adjustments are recommended due to lack of dedicated pharmacokinetic studies in pregnancy. Standard adult dosing (400 mg IV once daily) is used, with caution and consideration of increased clearance potential.
No dose adjustments required due to pregnancy; pharmacokinetics of electrolytes and water unchanged; adjust dosing based on clinical status and losses.
AVELOX (moxifloxacin) in sodium chloride 0.8% is a fluoroquinolone antibiotic for intravenous use. Avoid rapid infusion; administer over 60 minutes to reduce risk of infusion-related reactions. Monitor for QT prolongation, especially in patients with electrolyte disturbances or on antiarrhythmics. Avoid in patients with known aortic aneurysm or history of tendinopathy. Use caution in elderly and those with renal impairment. Not recommended for patients with myasthenia gravis due to risk of exacerbation.
Acetated Ringer's is an isotonic crystalloid containing acetate as a bicarbonate precursor; it does not require hepatic metabolism for alkalinization, unlike lactate, making it preferable in patients with hepatic impairment or lactic acidosis. Monitor serum electrolytes and acid-base status during infusion, especially in renal impairment. Do not administer through same IV line with blood products due to risk of hemolysis from calcium content. Avoid use in metabolic alkalosis.
