Gaticas
Gaticas Uses, Dosage, Side Effects, Food Interaction and all others data.
Gaticas is a fluoroquinolone antibacterial which acts by inhibiting DNA synthesis in susceptible organisms via inhibition of both DNA gyrase (essential for bacterial reproduction) and topoisomerase IV (essential during bacterial cell division).
Gaticas is a synthetic broad-spectrum 8-methoxyfluoroquinolone antibacterial agent for oral or intravenous administration. 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. Gaticas is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria. It should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria.

- Acute, uncomplicated rectal infections in women due to Neisseria gonorrhoeae.
Gaticas is also used to associated treatment for these conditions: Bacterial Conjunctivitis, Ocular Infections, Irritations and Inflammations
How Gaticas works
The bactericidal action of Gaticas results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination.

Gaticas can be administered without regard to food.
Side Effects
Gaticas is generally well tolerated. The most common side effects that can occur while taking this drug are usually mild and include nausea, vomiting, stomach pain, diarrhea, dizziness,and headache .
Precaution
Gaticas should be administered with caution in the presence of renal insufficiency.
Food Interaction
- Drink plenty of fluids.
- Take with or without food. The absorption is unaffected by food.
[Minor] Concurrent ingestion of calcium-fortified foods (i.e., cereal, orange juice) may alter the bioavailability of gatifloxacin.
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.
Data have been conflicting: One study has reported no effect with milk coadministration.
Another study reported a modest decrease in gatifloxacin bioavailability (13.5% decrease in Cmax,12% decrease in AUC, 15% increase in total clearance) when taken with 12 ounces of calcium-fortified orange juice instead of water, which could be clinically significant if the infecting organisms have borderline susceptibilities.
The manufacturer states that gatifloxacin may be taken without regard to food, milk, or calcium.
Clinicians should be aware of the possibility of an interaction if subtherapeutic effects are observed.
Gaticas 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
Pregnancy: Gaticas should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus.
Lactation: It is not known whether Gaticas is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when gatifloxacin is administered to a nursing woman.
Contraindication
Gaticas is contraindicated in patients with a history of hypersensitivity of Gaticas, quinolone antimicrobial agents, or any other components of this product.
