🔬 Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionOfloxacin is well absorbed after oral administration, with bioavailability >90%. Food may delay but does not significantly reduce absorption.

DistributionWidely distributed into body tissues and fluids, including lung, skin, bone, prostate, and cerebrospinal fluid (with inflamed meninges). Volume of distribution is approximately 1.5-2.5 L/kg.

Protein Binding20-25%

MetabolismMinimally metabolized in the liver; approximately 5-10% is metabolized to desmethyl ofloxacin and ofloxacin N-oxide.

Half-Life6-8 hours (prolonged in renal impairment)

ExcretionPrimarily excreted unchanged in urine (70-80%) via glomerular filtration and tubular secretion. A small amount is excreted in feces.

Bioavailability>90%

Onset of Action1-2 hours after oral administration

Peak Plasma Time1-2 hours

Duration of Action12-24 hours

How It Works

Ofloxacin is a fluoroquinolone antibiotic that inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, enzymes required for DNA replication, transcription, repair, and recombination. By binding to these enzymes, it prevents the supercoiling and uncoiling of bacterial DNA, leading to inhibition of DNA synthesis and ultimately bacterial cell death. This mechanism is bactericidal and concentration-dependent.

Mechanism Steps

1Ofloxacin enters bacterial cells via porin channels

2Binds to DNA gyrase and topoisomerase IV

3Inhibits DNA supercoiling and replication

💡 How to Take ofast 200mg tablet

1Take ofloxacin exactly as prescribed by your doctor.

2Swallow the tablet whole with a full glass of water. Do not crush or chew.

3Take at evenly spaced intervals (e.g., every 12 hours) to maintain a constant level in your blood.

4If you miss a dose, take it as soon as you remember, but skip if it's almost time for the next dose.

Dosage Information

Adult Dosage	200-400 mg orally every 12 hours for 7-14 days depending on infection. For uncomplicated UTI: 200 mg every 12 hours for 3 days. For gonorrhea: 400 mg single dose.
Pediatric Dosage	Not recommended for children <18 years due to risk of arthropathy. In exceptional cases, dose based on body weight: 7.5-15 mg/kg/day divided every 12 hours (max 400 mg/day).
Elderly Dosage	No specific adjustment except based on renal function. Start at lower end of dosing range.
Renal Impairment	CrCl 20-50 mL/min: 200-400 mg every 24 hours. CrCl <20 mL/min: 200 mg every 24 hours. Hemodialysis: 200 mg every 24 hours.

Pregnancy

Category C

🚫 Contraindications

Hypersensitivity to ofloxacin or any fluoroquinolone. History of tendon disorders related to fluoroquinolone use. Avoid in children and adolescents (<18 years) due to risk of arthropathy. Use in pregnancy (category C) and lactation only if benefit outweighs risk. Caution in patients with epilepsy, QT prolongation, or renal impairment.

🚫 Contraindicated Diseases

Tendon disorders
Epilepsy
QT prolongation
Myasthenia gravis

⚠️ Warnings & Precautions

Fluoroquinolones, including ofloxacin, have been associated with disabling and potentially irreversible serious adverse reactions involving tendons, muscles, joints, nerves, and the central nervous system. Discontinue immediately if signs of tendon pain, swelling, or rupture occur. Avoid in patients with a history of tendon disorders. Use with caution in patients with renal impairment (adjust dose), epilepsy, or other CNS disorders. May exacerbate myasthenia gravis. Monitor for signs of peripheral neuropathy. Avoid excessive sunlight/UV exposure due to photosensitivity. QT prolongation risk; avoid in patients with known QT prolongation, electrolyte imbalances, or concurrent use of QT-prolonging drugs. Clostridioides difficile-associated diarrhea has been reported. Use with caution in patients with aortic aneurysm or history of aortic dissection.

⚠️ FDA Warning

FDA warns about increased risk of tendinitis and tendon rupture, peripheral neuropathy, CNS effects, and exacerbation of myasthenia gravis. Avoid use in uncomplicated infections when other options are available.

📊 Monitoring Parameters

Renal function (especially in elderly and those with renal impairment), liver function, blood glucose (in diabetic patients), ECG (if QT prolongation risk), signs of tendonitis or neuropathy, and signs of hypersensitivity.

🤱 Lactation Safety

Ofloxacin is excreted in breast milk. Use with caution in nursing mothers; consider discontinuing br

Additional Safety Advice

Alcohol

Avoid alcohol as it may increase dizziness and drowsiness.

Pregnancy

Use only if clearly needed; risk to fetus cannot be ruled out.

Driving

May cause dizziness or drowsiness; avoid driving if affected.

Liver

Use with caution in severe liver disease.

Kidney

Dose adjustment required in renal impairment.

Diet & Lifestyle

Avoid dairy products, antacids, and iron/zinc supplements around the time of dosing.

💊 Overdose Management

In case of overdose, symptomatic and supportive care is recommended. No specific antidote. Monitor ECG for QT prolongation. Hemodialysis removes only a small amount of ofloxacin (10-20%).

⏰ Missed Dose

Take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and resume the regular schedule. Do not double the dose.

🛑 Myths vs. Facts

Myth: Ofloxacin is safe to take with any food.
