Oflagard Ol Uses, Dosage, Side Effects, Food Interaction and all others data.

Ofloxacin is a synthetic 4-fluoroquinolone antibacterial agent with bactericidal activity against a wide range of Gram-negative and Gram-positive organisms. Ofloxacin is thought to exert bactericidal effect by inhibiting DNA gyrase, an essential enzyme that is a critical catalyst in the duplication, transcription and repair of bacterial DNA.

Ofloxacin is a quinolone/fluoroquinolone antibiotic. Ofloxacin is bactericidal and its mode of action depends on blocking of bacterial DNA replication by binding itself to an enzyme called DNA gyrase, which allows the untwisting required to replicate one DNA double helix into two. Notably the drug has 100 times higher affinity for bacterial DNA gyrase than for mammalian. Ofloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria.

Ornidazole is a 5-nitroimidazole derivative active against protozoa and anaerobic bacteria. It is converted to reduction products that interact with DNA to cause destruction of helical DNA structure and strand leading to a protein synthesis inhibition and cell death in susceptible organisms.

How Oflagard Ol works

Ofloxacin acts on DNA gyrase and toposiomerase IV, enzymes which, like human topoisomerase, prevents the excessive supercoiling of DNA during replication or transcription. By inhibiting their function, the drug thereby inhibits normal cell division.

Dosage

Oflagard Ol dosage

Ofloxacin Eye: Instill 1 drop in the affected eye(s) every 2 to 4 hours for the first two days and then 4 times daily. The length of treatment should not exceed ten days.

Up to 400 mg may be given as a single dose, preferably in the morning, larger doses should be given as two divided doses. Ofloxacin tablets should be swallowed with liquid; they should not be taken within two hours of intake of magnesium/aluminium containing antacids or iron preparations since reduction of absorption of ofloxacin can occur.

  • Uncomplicated urethral and cervical gonorrhoea: A single dose of 400 mg.
  • Non-gonococcal urethral and cervicitis: 400 mg daily in single or divided doses.
  • Complicated Urinary Tract Infection: 200/400 mg/day for 7 days.

Children: Ofloxacin is usually not indicated for use in children or growing adolescents.

Elderly: No adjustment of dosage is required in the elderly.

Side Effects

Ofloxacin Eye: Transient ocular irritation, burning, stinging, redness, itching or photophobia have been reported.

Ofloxacin Ear: Mild irritation or mild discomfort in the ear may occur. Symptoms of an allergic reaction include rash, itching, swelling or trouble breathing.

Ofloxacin tablet or injection is generally well tolerated and clinical side-effects of ofloxacin has been quite low. Among the adverse effects gastrointestinal and central nervous systems' reactions are common. Nausea, rash, vomiting, abdominal pain, diarrhoea and gastrointestinal distress are the gastrointestinal adverse effects. Common central nervous system reactions are headache, dizziness and insomnia.

Side effects of Ornidazole have been mainly limited to the gastrointestinal tract (nausea, vomiting, epigastric pain) and central nervous system (dizziness, headache, lassitude). Unlike other nitroimidazoles, Ornidazole does not interact with alcohol, although this requires further study.

Leukopenia has been described occasionally during therapy. Adverse central nervous system (CNS) effects of Ornidazole have mainly included headache, dizziness, lassitude or somnolence, fatigue and weakness. Adverse CNS effects of Ornidazole may be less than that happens with metronidazole. Seizures have not been reported with Ornidazole in studies available to date.

Toxicity

LD50=5450 mg/kg (orally in mice)

Precaution

Patients being treated with Ofloxacin should not expose themselves unnecessarily to strong sunlight and should avoid UV rays. Caution is recommended if the drug is to be used in psychotic patients or in-patients with a history of psychiatric disease.

Prolonged use of eye drops & ear drops may result in overgrowth of non-susceptible organisms and secondary infection respectively.

In patient with ataxia, vertigo, and mental confusion, Ornidazole should be prescribed with caution. During prolonged treatment with Ornidazole, blood dyscrasia namely mild leukopenia have been reported rarely. In case leukopenia occurs, the decision to discontinue the therapy should depend upon the gravity of infection.

Interaction

Antacids containing magnesium, aluminium or calcium may decrease absorption of ofloxacin. Iron or Zinc may decrease oral absorption of ofloxacin.

Like other imidazoles, Ornidazole has a mild potential to cause disulfiramlike reactions. Concomitant administration of oral anticoagulants may increase the risk of haemorrhage due to diminished hepatic metabolism. Ornidazole has been reported to decrease the clearance of 5-fluorouracil.

Elimination Route

Bioavailability of ofloxacin in the tablet formulation is approximately 98%

Half Life

9 hours

Elimination Route

Ofloxacin is mainly eliminated by renal excretion, where between 65% and 80% of an administered oral dose of ofloxacin is excreted unchanged via urine within 48 hours of dosing. About 4-8% of an ofloxacin dose is excreted in the feces and the drug is minimally subject to biliary excretion.

Pregnancy & Breastfeeding use

Use in pregnancy: There are no adequate and well-controlled studies in pregnant women. This drug should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Use in lactation: It is not known whether Ofloxacin is excreted in human milk. Cautions should be taken when Ofloxacin eye & ear drops is administered during lactation.

Adequate clinical trials have not been conducted. Ornidazole should be prescribed only if the potential benefit justifies the potential risk to fetus/neonate.

Contraindication

It is contraindicated in patients who are hypersensitive to Ofloxacin or any other component of Ofloxacin (Eye/Ear Drops).

Ofloxacin tablet injection should not be used in-patients with known hypersensitivity to 4-fluoroquinolone antibacterials. It is contraindicated in-patients with a history of epilepsy or with a lowered seizure threshold. Ofloxacin is usually contraindicated in children or growing adolescents and in pregnant or breast feeding women.

Previous hypersensitivity to Ornidazole and to other nitroimidazoles. Ornidazole is contraindicated in central nervous system disorders, particularly in epilepsy or in peripheral neuropathy.
