Optra

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

Optra is a synthetic 4-fluoroquinolone antibacterial agent with bactericidal activity against a wide range of Gram-negative and Gram-positive organisms. Optra 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.

Optra is a quinolone/fluoroquinolone antibiotic. Optra 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. Optra is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria.

How Optra works

Optra 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

Optra dosage

Optra 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.

Optra Ear: Instill 1-2 drops in the affected ear(s) twice daily or as needed.

Optra Intravenous (Adult):

  • Skin and soft tissue infections: 400 mg bid infused over at least 1 hr.
  • Complicated urinary tract infections: 200 mg daily by infusion over at least 30 min. Max: 400 mg bid infused over at least 1 hr.
  • Lower respiratory tract infections, Septicaemia: 200 mg bid by infusion over at least 30 min. Max: 400 mg bid infused over at least 1 hr.

Up to 400 mg may be given as a single dose, preferably in the morning, larger doses should be given as two divided doses. Optra 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.

  • Enteric fever: For adults 200 mg, every 12 hours, for 5 days. For children 15 mg/kg/day in 2 divided doses for 3 days.
  • Shigellosis: 400 mg single dose.
  • Multi-drug-resistant tuberculosis: 400 mg twice daily along with conventional anti-tuberculosis drugs.
  • Lower respiratory tract infection: 400 mg daily, increasing, if necessary, to 400 mg twice daily.
  • Uncomplicated Urinary Tract Infections: A single dose of 200/400 mg.
  • 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: Optra is usually not indicated for use in children or growing adolescents.

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

May be taken with or without food. Avoid antacids or supplements containing Fe or Zn within 2 hr before or after ofloxacin. Ensure adequate hydration.

Toxicity

LD50=5450 mg/kg (orally in mice)

Precaution

Patients being treated with Optra 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.

Interaction

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

Food Interaction

  • Limit caffeine intake.
  • Take with or without food. The absorption is unaffected by food.

Optra multivitamins interaction

[Moderate] ADJUST DOSING INTERVAL: Oral preparations that contain magnesium, aluminum, or calcium may significantly decrease the gastrointestinal absorption of quinolone antibiotics.

Absorption may also be reduced by sucralfate, which contains aluminum, as well as other polyvalent cations such as iron and zinc.

The mechanism is chelation of quinolones by polyvalent cations, forming a complex that is poorly absorbed from the gastrointestinal tract.

The bioavailability of ciprofloxacin has been reported to decrease by as much as 90% when administered with antacids containing aluminum or magnesium hydroxide.

When coadministration cannot be avoided, quinolone antibiotics should be dosed either 2 to 4 hours before or 4 to 6 hours after polyvalent cation-containing products to minimize the potential for interaction.

When coadministered with Suprep Bowel Prep (magnesium

Please consult individual product labeling for specific recommendations.

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.
