🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is rapidly and almost completely absorbed from the gastrointestinal tract after oral administration. Food may slightly delay absorption but does not significantly reduce the extent of absorption.
DistributionThis medicine distributes widely into body tissues and fluids, including lung, kidney, prostate, and bile. It also penetrates into cerebrospinal fluid to some extent, especially when meninges are inflamed.
Protein BindingApproximately 20-30% bound to plasma proteins.
MetabolismThis medicine is minimally metabolized in the liver. Only a small fraction is metabolized to N-desmethyl ofloxacin and ofloxacin N-oxide.
Half-LifeThe elimination half-life is approximately 4 to 5 hours in patients with normal renal function, but it is prolonged in renal impairment.
ExcretionThis medicine is primarily excreted unchanged in the urine by glomerular filtration and tubular secretion. About 70-80% of an oral dose is recovered in urine within 24 hours.
BioavailabilityThe oral bioavailability is approximately 95-100%.
Onset of ActionThe onset of antibacterial action is rapid, typically within 1-2 hours after oral administration.
Peak Plasma TimePeak plasma concentrations are achieved within 1 to 2 hours after oral administration.
Duration of ActionThe antibacterial effect lasts for approximately 12 to 24 hours, depending on the dose and susceptibility of the organism.

How It Works

This medicine exerts its antibacterial effect by inhibiting two key enzymes in bacteria: DNA gyrase (topoisomerase II) and topoisomerase IV. These enzymes are responsible for supercoiling and uncoiling of bacterial DNA during replication, transcription, and repair. By binding to these enzymes, this medicine blocks the re-ligation step of the DNA strand, leading to double-stranded DNA breaks and ultimately bacterial cell death. This action is bactericidal and concentration-dependent.

Mechanism Steps

1
Entry into bacterial cell: This medicine penetrates the bacterial cell wall and cytoplasmic membrane through porin channels.
2
Binding to DNA gyrase: It binds to the DNA gyrase enzyme, stabilizing the enzyme-DNA complex and preventing DNA supercoiling.
3
Inhibition of topoisomerase IV: It also inhibits topoisomerase IV, which is involved in separating interlinked DNA strands during replication.
4
DNA damage and cell death: The inhibition leads to double-stranded DNA breaks, blocking replication and transcription, resulting in bacterial cell death.

Dosage Information

Adult DosageThe usual adult dose of this medicine for most infections is 200 mg to 400 mg taken orally every 12 hours, or 400 mg once daily, depending on the type and severity of infection. For uncomplicated urinary tract infections, 200 mg every 12 hours for 3 to 7 days is common. For respiratory tract infections, 400 mg every 12 hours for 7 to 14 days may be used. For typhoid fever, 400 mg every 12 hours for 7 to 14 days. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician. This medicine is generally not recommended for children under 18 years of age due to risk of cartilage damage.
Elderly DosageElderly patients may have reduced renal function and are at higher risk of tendon rupture and CNS effects. Dose should be adjusted based on renal function. Use with caution.
Renal ImpairmentIn patients with renal impairment (creatinine clearance <50 mL/min), dose adjustment is required. For creatinine clearance 20-50 mL/min, the usual dose is 200 mg every 24 hours. For creatinine clearance <20 mL/min, 200 mg every 48 hours or as directed by a clinician. Dose must be individualized by a qualified clinician.
Hepatic ImpairmentNo specific dose adjustment is generally required for hepatic impairment, as this medicine is minimally metabolized in the liver. However, use with caution in severe hepatic disease.
Maximum Daily DoseThe maximum recommended daily dose is 800 mg per day in divided doses for adults with normal renal function.
