Op Lox
Op Lox Uses, Dosage, Side Effects, Food Interaction and all others data.
Op Lox is a synthetic 4-fluoroquinolone antibacterial agent with bactericidal activity against a wide range of Gram-negative and Gram-positive organisms. Op Lox 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.
Op Lox is a quinolone/fluoroquinolone antibiotic. Op Lox 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. Op Lox is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria.

How Op Lox works
Op Lox 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
Op Lox dosage
Op Lox 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.
Op Lox Ear: Instill 1-2 drops in the affected ear(s) twice daily or as needed.

Op Lox 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.

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.
Op Lox 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.
