Orsanac

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

A synthetic fluoroquinolone (fluoroquinolones) with broad-spectrum antibacterial activity against most gram-negative and gram-positive bacteria. Orsanac inhibits bacterial DNA gyrase.

Orsanac is a quinolone/fluoroquinolone antibiotic. Orsanac 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.

Uses

Orsanac is a broad-spectrum fluoroquinolone antibiotic with variable activity against gram-positive and gram-negative bacteria. Typically reserved for the treatment of UTIs due to accumulation in the urine.

For the treatment of urinary tract infection

Orsanac is also used to associated treatment for these conditions: Cystitis, Gonococcal cervicitis, Infectious diarrhea, Pyelitis, Pyelonephritis, Spontaneous Bacterial Peritonitis (SBP), Traveler's Diarrhea, Urethritis gonococcal

How Orsanac works

The bactericidal action of Orsanac results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination. Orsanac is a broad-spectrum antibiotic agent that is shown to be effective against various Gram-positive and Gram-negative bacterial species. The fluorine atom at the 6 position increases potency against gram-negative organisms, and the piperazine moiety at the 7 position is responsible for anti-pseudomonal activity

Food Interaction

  • Drink plenty of fluids.
  • Limit caffeine intake.
  • Take on an empty stomach.

[Moderate] ADJUST DOSING INTERVAL: Concurrent ingestion of meals, dairy products (milk, yogurt) or calcium-fortified foods (i.e., cereal, orange juice) may decrease the absorption of oral norfloxacin.

The mechanism is chelation of calcium and the quinolone, resulting in decreased bioavailability.

In the case of orange juice, inhibition of intestinal transport mechanisms (P-glycoprotein or organic anion-transporting polypeptides) by flavones may also be involved.



MANAGEMENT: Oral norfloxacin should be taken at least one hour before or two hours after a meal, milk, or other dairy products or calcium-fortified foods.

Orsanac 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

Half Life

3-4 hours

Elimination Route

Orsanac is eliminated through metabolism, biliary excretion, and renal excretion. It is expected to undergo both glomerular filtration and tubular secretion during renal excretion, as shown by its high renal clearance rate of approximately 275 mL/min.
