Lomefloxacin - Yellow River Pharm
Lomefloxacin - Yellow River Pharm Uses, Dosage, Side Effects, Food Interaction and all others data.
Lomefloxacin - Yellow River Pharm, a difluorinated quinolone derivative, is a bacterial gyrase inhibitor, effective against gram positive and gram negative bacteria. The acute toxicity of Lomefloxacin - Yellow River Pharm following systemic and topical ophthalmic application is low. Lomefloxacin - Yellow River Pharm interferes with bacterial DNA related processes like initiation, elongation, and termination phases of replication, transcription, DNA repairing, recombination, transposition, supercoiling and relaxation of DNA. The target molecule for quinolones is the A-subunit of bacterial enzyme gyrase (topoisomerase II). The forming of a stable complex between the quinolone and the whole gyrase teramer A2B2 leads to impaired enzyme functions, resulting in a rapid killing of sensitive bacteria.
Cross-resistance has only been reported with other quinolones, but not with any other group of antibiotics. No clinical studies are available about the efficacy in cases of infections with chlamydia.
Lomefloxacin - Yellow River Pharm is a fluoroquinolone antibiotic used to treat chronic bronchitis, as well as complicated and uncomplicated urinary tract infections. It is also used as a prophylactic or preventative treatment to prevent urinary tract infections in patients undergoing transrectal or transurethral surgical procedures. Flouroquinolones such as lomefloxacin possess excellent activity against gram-negative aerobic bacteria such as E.coli and Neisseria gonorrhoea as well as gram-positive bacteria including S. pneumoniae and Staphylococcus aureus. They also posses effective activity against shigella, salmonella, campylobacter, gonococcal organisms, and multi drug resistant pseudomonas and enterobacter.

How Lomefloxacin - Yellow River Pharm works
Lomefloxacin - Yellow River Pharm is a bactericidal fluoroquinolone agent with activity against a wide range of gram-negative and gram-positive organisms. The bactericidal action of lomefloxacin results from interference with the activity of the bacterial enzymes DNA gyrase and topoisomerase IV, which are needed for the transcription and replication of bacterial DNA. DNA gyrase appears to be the primary quinolone target for gram-negative bacteria. Topoisomerase IV appears to be the preferential target in gram-positive organisms. Interference with these two topoisomerases results in strand breakage of the bacterial chromosome, supercoiling, and resealing. As a result DNA replication and transcription is inhibited.

Side Effects
Common side effects are Nausea, headache, photosensitivity, dizziness, diarrhea, dry mouth, fatigue, convulsions, CNS stimulation which may lead to tremors, restlessness, light headedness, confusion hallucinations and pseudomembranous colitis.
Slight and transient burning immediately after instillation of the eye drops has been reported in 4.7% of users. Although phototoxicity has not been reported after ophthalmic use, photosensitization is possible. Since the following allergic reactions have been reported after systemic use of Lomefloxacin - Yellow River Pharm, they can not be excluded after topical ophthalmic use: allergic reactions, asthma, dyspnoea, urticaria, erythema, pruritus, and hypersensitization.
Toxicity
Adverse reactions include peripheral neuropathy, nervousness, agitation, anxiety, and phototoxic events (rash, itching, burning) due to sunlight exposure.
Precaution
Alterations of the dosage regimen is recommended for patients with impairment of renal function (CrCl <40 ml/min/1.73 m2). Avoid exposure to excessive sunlight or artificial UV light. Phototoxicity reaction may occur if undue exposure occurs. Safety and efficacy of Lomefloxacin - Yellow River Pharm has not been established in children, pregnant and lactating women.
Some isolated cases of phototoxicity have been reported after systemic but not after topical ophthalmic use of Lomefloxacin - Yellow River Pharm. Nevertheless, during treatment with Lomefloxacin - Yellow River Pharm intensive exposure to sunlight or UV-radiation should be avoided
Interaction
Lomefloxacin - Yellow River Pharm does not alter theophylline clearance and concentration. No change of caffeine is reported. Sucralfate and antacid containing magnesium and aluminium interfere with its bioavailability. Enhances effects of warfarin. Probenecid slows renal elimination of Lomefloxacin - Yellow River Pharm.
In order to avoid reduction of efficacy, no ophthalmic preparations containing heavy metals, such as zinc, should be used during 15 minutes preceding and following application of Lomefloxacin - Yellow River Pharm. Bacteriostatic ophthalmic antibiotics should not be used concomitantly with Lomefloxacin - Yellow River Pharm eye drops.
Food Interaction
- Avoid multivalent ions. Separate the administration polyvalent ions, including magnesium and aluminum-containing antacids, from lomefloxacin by at least 4 hours before and 2 hours after lomefloxacin dosing.
- Take with or without food. The rate and extent of absorption may be reduced when lomefloxacin is taken with food.
Lomefloxacin - Yellow River Pharm 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 Category C. Reproductive function studies have been performed in rats at doses up to 8 times the recommended human dose based on mg/m² (34 times the recommended human dose based on mg/kg), and no impaired fertility or harm to the fetus was reported due to lomefloxacin. Increased incidence of fetal loss in monkeys has been observed at approximately 3 to 6 times the recommended human dose based on mg/m² (6 to 12 times the recommended human dose based on mg/kg). No teratogenicity has been observed in rats and monkeys at up to 16 times the recommended human dose exposure. In the rabbit, maternal toxicity and associated fetotoxicity, decreased placental weight, and variations of the coccygeal vertebrae occurred at doses 2 times the recommended human exposure based on mg/m². There are, however, no adequate and well-controlled studies in pregnant women. Lomefloxacin - Yellow River Pharm should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Nursing mothers: It is not known whether lomefloxacin is excreted in human milk. However, it is known that other drugs of this class are excreted in human milk and that lomefloxacin is excreted in the milk of lactating rats. Because of the potential for serious adverse reactions from lomefloxacin in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Contraindication
Lomefloxacin - Yellow River Pharm is contraindicated in patients with a history of hypersensitivity to Lomefloxacin - Yellow River Pharm or to other quinolones. Lomefloxacin - Yellow River Pharm like other drugs in its class, cause arthropathy in juvenile animals. Therefore, its use in children, growing adolescents, and pregnant women is not recommended.
Special Warning
Pediatric use: The safety and effectiveness of lomefloxacin in pediatric patients and adolescents less than 18 years of age have not been established. Lomefloxacin - Yellow River Pharm causes arthropathy in juvenile animals of several species.
Geriatric use: Of the total number of subjects in clinical studies of lomefloxacin, 25% were ≥65 years and 9% were ≥ 75 years. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
