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

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

Ofspan Dt 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.
