🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLevofloxacin is rapidly and almost completely absorbed after oral administration, with bioavailability approaching 99%. Ornidazole is also well absorbed orally, with peak plasma concentrations reached within 2-3 hours. Food may slightly delay absorption but does not significantly reduce the extent.
DistributionLevofloxacin distributes widely into body tissues and fluids, including lung, prostate, and skin. It penetrates well into inflammatory fluids. Ornidazole also distributes widely, including into the central nervous system and liver. Both agents cross the placenta and are excreted in breast milk.
Protein BindingLevofloxacin is approximately 24-38% bound to plasma proteins. Ornidazole is about 13% bound to plasma proteins.
MetabolismLevofloxacin undergoes limited metabolism in the liver, with less than 5% metabolized. Ornidazole is metabolized in the liver primarily by conjugation and oxidation.
Half-LifeThe elimination half-life of levofloxacin is approximately 6-8 hours in adults with normal renal function. The elimination half-life of ornidazole is approximately 12-14 hours.
ExcretionLevofloxacin is primarily excreted unchanged in the urine (about 70-87% of an oral dose). Ornidazole is excreted mainly in the urine as metabolites and in feces.
BioavailabilityLevofloxacin oral bioavailability is approximately 99%. Ornidazole oral bioavailability is high, approximately 90%.
Onset of ActionThe onset of antimicrobial action begins within 1-2 hours after oral administration, but clinical improvement may take 24-48 hours.
Peak Plasma TimeLevofloxacin peak plasma concentration occurs 1-2 hours after oral dosing. Ornidazole peak plasma concentration occurs 2-3 hours after oral dosing.
Duration of ActionThe antimicrobial effect persists for at least 24 hours for levofloxacin and up to 24-36 hours for ornidazole, allowing for once or twice daily dosing.

How It Works

This medicine combines two antimicrobial agents with distinct mechanisms. Levofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, repair, and recombination. This leads to inhibition of bacterial cell division and ultimately cell death. Ornidazole is a nitroimidazole that enters susceptible anaerobic bacteria and protozoa, where its nitro group is reduced to reactive intermediates that damage DNA, causing strand breakage and cell death. The combination provides broad coverage against aerobic gram-negative and gram-positive bacteria (from levofloxacin) and anaerobic bacteria and protozoa (from ornidazole).

Mechanism Steps

1
Levofloxacin entry and target binding: Levofloxacin enters bacterial cells and binds to DNA gyrase and topoisomerase IV, blocking their activity.
2
Inhibition of DNA replication: This prevents the supercoiling and relaxation of DNA needed for replication, leading to bacterial cell death.
3
Ornidazole activation: Ornidazole diffuses into anaerobic organisms and protozoa, where its nitro group is reduced by ferredoxin-like proteins.
4
DNA damage by reactive intermediates: The reduced intermediates bind to DNA, causing strand breaks and inhibiting nucleic acid synthesis.
5
Cell death: The combined damage from both agents leads to death of susceptible microorganisms.

💡 How to Take levoquin oz tablet

Strength: Each tablet contains levofloxacin 250 mg and ornidazole 500 mg.

1Take the tablet orally with a full glass of water.
2Take with food to reduce stomach upset.
3Swallow the tablet whole; do not crush or chew.
4Take at the same time each day to maintain consistent levels.
5Avoid taking antacids, iron, or zinc supplements within 2 hours before or 6 hours after this medicine.
6Complete the full course as prescribed, even if you feel better.

Dosage Information

Adult DosageThe usual adult dose of this medicine is one tablet taken orally once or twice daily, depending on the severity and type of infection. The duration of treatment is typically 5 to 10 days but may vary based on the infection and clinical response. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not self-adjust the dose.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may require dose adjustment based on renal function. Levofloxacin is primarily excreted by the kidneys, and renal function declines with age. Monitor closely for side effects such as tendon rupture and CNS effects.
Renal ImpairmentIn patients with renal impairment (creatinine clearance <50 mL/min), the dose of levofloxacin should be adjusted. Ornidazole does not require dose adjustment in renal impairment. Consult your doctor for specific dosing.
Hepatic ImpairmentNo specific dose adjustment is established for hepatic impairment. Use with caution and monitor liver function.
Maximum Daily DoseThe maximum recommended daily dose is levofloxacin 750 mg and ornidazole 1500 mg, but the exact maximum for this combination depends on the indication and clinical judgment. Do not exceed the prescribed dose.
