What is Levofloxacine EG?
Levofloxacine EG injection is used to treat bacterial infections in many different parts of the body. It is also used to prevent an anthrax infection after a person has been exposed to anthrax. Levofloxacine EG is also used to treat and prevent plague (including pneumonic and septicemic plague).
Levofloxacine EG belongs to the class of medicines known as quinolone antibiotics. It works by killing bacteria or preventing their growth. However, Levofloxacine EG will not work for colds, flu, or other virus infections.
Levofloxacine EG is to be given only by or under the direct supervision of your doctor.
Levofloxacine EG indications
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Levofloxacine EG Tablets, USP and other antibacterial drugs, Levofloxacine EG Tablets, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
Levofloxacine EG Tablets, USP is indicated for the treatment of adults (≥18 years of age) with mild, moderate, and severe infections caused by susceptible isolates of the designated microorganisms in the conditions listed in this section.
Culture and susceptibility testing

Levofloxacine EG description
Each tablet contains Levofloxacin 250 mg as active ingredient corresponding to Levofloxacine EG hemihydrate 256.23 mg.
Levofloxacine EG also contains the following inactive ingredients: Sodium chloride; sodium hydroxide; hydrochloric acid (qs: pH 4.8) and water for injection for a volume of 100 mL (Na+ concentration: 154 mmol/L).
Levofloxacine EG is a synthetic broad-spectrum antibacterial agent for oral and IV administration. Chemically, Levofloxacine EG, a chiral fluorinated carboxyquinolone, is the pure (-)-(S)-enantiomer of the racemic drug substance ofloxacin. Levofloxacine EG is (-)-(S)-9-fluoro-2,3-dihydro-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-7H-pyrido[1,2,3-de]-1,4 benzoxazine-6-carboxylic acid hemihydrate.
Its empirical formula is C18H20FN3O4·½H2O and its molecular weight is 370.38.
Levofloxacine EG is a light yellowish-white to yellow-white crystal or crystalline powder. The molecule exists as a zwitterion at the pH conditions in the small intestine. The data demonstrate that from pH 0.6-5.8, the solubility of Levofloxacine EG is essentially constant (approximately 100 mg/mL). Levofloxacine EG is considered soluble to freely soluble in this pH range, as defined by USP nomenclature. Above pH 5.8, the solubility increases rapidly to its maximum at pH 6.7 (272 mg/mL) and is considered freely soluble in this range. Above pH 6.7, the solubility decreases and reaches a minimum value (about 50 mg/mL) at a pH of approximately 6.9. Levofloxacine EG has the potential to form stable coordination compounds with many metal ions. This in vitro chelation potential has the following formation order: A1+3 > Cu+2 > Zn+2 > Mg+2 > Ca+2.
Levofloxacine EG dosage
Dosage in Adult Patients with Normal Renal Function
The usual dose of Levofloxacine EG
Oral Solution is 250 mg, 500 mg, or 750 mg administered orally every 24 hours, as indicated by infection and described in Table 1.
These recommendations apply to patients with creatinine clearance ≥ 50 mL/min. For patients with creatinine clearance <50 mL/min, adjustments to the dosing regimen are required.
Dosage in Pediatric Patients
The dosage in pediatric patients ≥ 6 months of age is described below in Table 2.
Dosage Adjustment in Adults with Renal Impairment
Administer Levofloxacine EG with caution in the presence of renal insufficiency. Careful clinical observation and appropriate laboratory studies should be performed prior to and during therapy since elimination of Levofloxacine EG may be reduced.
No adjustment is necessary for patients with a creatinine clearance ≥ 50 mL/min.
In patients with impaired renal function (creatinine clearance <50 mL/min), adjustment of the dosage regimen is necessary to avoid the accumulation of Levofloxacine EG due to decreased clearance.
Table 3 shows how to adjust dose based on creatinine clearance.
Drug Interaction With Chelation Agents: Antacids, Sucralfate, Metal Cations, Multivitamins
Levofloxacine EG
Oral Solution

What other drugs will affect Levofloxacine EG?
To avoid incomplete absorption of oral Levofloxacine EG, antacids containing magnesium hydroxide and/or aluminium hydroxide should not be used concomitantly. The administration of these drugs are recommended at least 2 hrs before or 2 hrs after Levofloxacine EG administration.
The studies showed that there are no significant interactions between Levofloxacine EG with theophylline, warfarin, cyclosporin, digoxin, probenecid and cimetidine. However, concomitant administration of other quinolones with the drugs previously mentioned may change the pharmacokinetic and pharmacodynamic properties significantly. Therefore, the drugs listed as follows must be considered if Levofloxacine EG is co-administered:
Theophylline: Theophylline levels should be closely monitored and appropriate dosage adjustments made.
Warfarin: Prothrombin time or other suitable anticoagulation test should be monitored.
Cyclosporin: No significant clinical changes, hence no dosage adjustment of cyclosporin or Levofloxacine EG is required.
Digoxin: No significant clinical changes, hence no dosage adjustment of digoxin or Levofloxacine EG is required.
The concomitant administration of NSAID with a quinolone, including Levofloxacine EG, may increase the risk of CNS stimulation and convulsive seizures.
Disturbances of blood glucose, including hyperglycemia and hypoglycemia, have been reported in patients receiving quinolones concomitantly with oral antidiabetic drugs. Therefore, careful monitoring of blood glucose is recommended when these agents are co-administered.

Hypotension has been associated with rapid or bolus intravenous infusion of Levofloxacine EG. Levofloxacine EG should be infused slowly over 60 to 90 minutes, depending on dosage.
Crystalluria and cylindruria have been reported with quinolones, including Levofloxacine EG. Therefore, adequate hydration of patients receiving Levofloxacine EG should be maintained to prevent the formation of a highly concentrated urine.
Clinical Trial Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The data described below reflect exposure to Levofloxacine EG in 7537 patients in 29 pooled Phase 3 clinical trials. The population studied had a mean age of 50 years (approximately 74% of the population was < 65 years of age), 50% were male, 71% were Caucasian, 19% were Black. Patients were treated with Levofloxacine EG for a wide variety of infectious diseases. Patients received Levofloxacine EG doses of 750 mg once daily, 250 mg once daily, or 500 mg once or twice daily. Treatment duration was usually 3 to 14 days, and the mean number of days on therapy was 10 days.
The overall incidence, type and distribution of adverse reactions was similar in patients receiving Levofloxacine EG doses of 750 mg once daily, 250 mg once daily, and 500 mg once or twice daily. Discontinuation of Levofloxacine EG due to adverse drug reactions occurred in 4.3% of patients overall, 3.8% of patients treated with the 250 mg and 500 mg doses and 5.4% of patients treated with the 750 mg dose. The most common adverse drug reactions leading to discontinuation with the 250 and 500 mg doses were gastrointestinal (1.4%), primarily nausea (0.6%); vomiting (0.4%); dizziness (0.3%); and headache (0.2%). The most common adverse drug reactions leading to discontinuation with the 750 mg dose were gastrointestinal (1.2%), primarily nausea (0.6%), vomiting (0.5%); dizziness (0.3%); and headache (0.3%).
Adverse reactions occurring in ≥1% of Levofloxacine EG-treated patients and less common adverse reactions, occurring in 0.1 to <1% of Levofloxacine EG-treated patients, are shown in Table 6 and Table 7, respectively. The most common adverse drug reactions (≥3%) are nausea, headache, diarrhea, insomnia, constipation, and dizziness.
In clinical trials using multiple-dose therapy, ophthalmologic abnormalities, including cataracts and multiple punctate lenticular opacities, have been noted in patients undergoing treatment with quinolones, including Levofloxacine EG. The relationship of the drugs to these events is not presently established.
Postmarketing Experience
Table 8 lists adverse reactions that have been identified during post-approval use of Levofloxacine EG. Because these reactions are reported voluntarily from a population of uncertain size, reliably estimating their frequency or establishing a causal relationship to drug exposure is not always possible.
Levofloxacine EG contraindications

What is the most important information I should know about Levofloxacine EG?
Patients hypersensitive to Levofloxacine EG or any other quinolones or any excipients of Levofloxacine EG. Patients with epilepsy and those with history of tendon disorder related to fluoroquinolone administration.
Use in pregnancy: Levofloxacine EG caused no impairment of fertility or reproductive performance in rats at oral doses as high as 360 mg/kg/day. It was not teratogenic in rats at oral doses as high as 810 mg/kg/day or at IV dose up to 160 mg/kg/day. No teratogenicity was observed when rabbits were dosed orally as high as 50 mg/kg/day.
In the absence of human data and due to the experimental risk of damage by fluoroquinolones to the weight-bearing cartilage of the growing organism, Levofloxacine EG must not be used in pregnant women or women suspected of being pregnant.
Use in lactation: In the absence of human data and due to the experimental risk of damage by fluoroquinolones to the weight-bearing cartilage of the growing organism, Levofloxacine EG must not be used in breastfeeding women.
Use in children: Safety and effectiveness in pediatric patients and adolescents <16 years have not been established. Quinolones, including Levofloxacine EG, cause arthropathy and osteochondrosis in juvenile animals of several species.
Use in
Elderly: The pharmacokinetic properties of Levofloxacine EG in younger adults and elderly do not differ significantly when creatinine clearance is taken into consideration. However, since Levofloxacine EG is known to be substantially excreted by the kidney, the risk of toxic reactions to Levofloxacine EG may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection and it may be useful to monitor renal function.
