Trovan
Trovan Uses, Dosage, Side Effects, Food Interaction and all others data.
Trovan is a broad spectrum antibiotic that has been commonly marketed under the brand name Trovan by Pfizer. It exerts its antibacterial activity by inhibiting the uncoiling of supercoiled DNA in various bacteria by blocking the activity of DNA gyrase and topoisomerase IV. It was shown to be more effective against Gram-positive bacteria than Gram-negative bacteria when compared to previous fluoroquinolones. Due to its hepatotoxic potential, trovafloxacin was withdrawn from the market.
Trovan is a broad spectrum antibiotic that inhibits DNA supercoiling in various bacteria by blocking the activity of DNA gyrase and topoisomerase IV. It is not used widely due to the risk of hepatotoxicity. It tends to have better gram-positive bacterial coverage and less gram-negative coverage than the previous fluoroquinolones. Mechanism of action of fluoroquinolones including trovafloxacin is different from that of penicillins, cephalosporins, aminoglycosides, macrolides, and tetracyclines. Therefore fluoroquinolones may be active against pathogens that are resistant to these antibiotics. There is no cross-resistance between trovafloxacin and the mentioned classes of antibiotics. The overall results obtained from in vitro synergy studies, testing combinations of trovafloxacin with beta-lactams and aminoglycosides, indicate that synergy is strain specific and not commonly encountered. This agrees with results obtained previously with other fluoroquinolones. Resistance to trovafloxacin in vitro develops slowly via multiple-step mutation in a manner similar to other fluoroquinolones. Resistance to trovafloxacin in vitro occurs at a general frequency of between 1x10-7 to 10-10. Although cross-resistance has been observed between trovafloxacin and some other fluoroquinolones, some microorganisms resistant to other fluoroquinolones may be susceptible to trovafloxacin.

Uses
Trovan is an antibiotic used to treat gonorrhea and chlamydia.
For treatment of infections caused by susceptible strains of the designated microorganisms in uncomplicated urethral gonorrhea in males and endocervical and rectal gonorrhea in females caused by Neisseria gonorrhoeae as well as non gonoccocal urethritis and cervicitis due to Chlamydia trachomatis.
Trovan is also used to associated treatment for these conditions: Community Acquired Pneumonia (CAP), Complicated Intra-Abdominal Infections, Complicated Skin and Skin Structure Infection, Nosocomial Pneumonia, Pelvic Infections
How Trovan works
Trovan is a fluoronaphthyridone related to the fluoroquinolones with in vitro activity against a wide range of gram-negative and gram-positive aerobic and anaerobic microorganisms. The bactericidal action of trovafloxacin results from inhibition of DNA gyrase and topoisomerase IV. DNA gyrase is an essential enzyme that is involved in the replication, transcription, and repair of bacterial DNA. Topoisomerase IV is an enzyme known to play a key role in the partitioning of the chromosomal DNA during bacterial cell division.
Toxicity
Symptoms of overdose include convulsions, decreased activity, diarrhea, sleepiness, tremors, and/or vomiting.
Food Interaction
- Avoid multivalent ions.
- Take separate from antacids. Take at least 2 hours before or after antacids.
- Take with or without food. Taking trovafloxacin with food may reduce the risk of dizziness.
Trovan 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.
Trovan Disease Interaction
Major: CNS disorders, myasthenia gravis, peripheral neuropathy, tendonitis, liver disease
Elimination Route
Well-absorbed from the gastrointestinal tract after oral administration and does not depend on concomitant food intake. The absolute bioavailability is approximately 88%.
Half Life
Following oral administration, half-life ranged from 9.1 hours to 12.2 hours over the dosage range of 100 to 200 mg tablets. Following intravenous infusion, half-life ranged from 9.4 to 12.7 hours over a dosage range of 100 to 300 mg.
Elimination Route
Approximately 50% of an oral dose is excreted unchanged (43% in the feces and 6% in the urine).
