Levofloxacin 1.5.% FFP description

Each tablet contains Levofloxacin 250 mg as active ingredient corresponding to Levofloxacin 1.5.% FFP hemihydrate 256.23 mg.

Levofloxacin 1.5.% FFP 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).

Levofloxacin 1.5.% FFP is a synthetic broad-spectrum antibacterial agent for oral and IV administration. Chemically, Levofloxacin 1.5.% FFP, a chiral fluorinated carboxyquinolone, is the pure (-)-(S)-enantiomer of the racemic drug substance ofloxacin. Levofloxacin 1.5.% FFP 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.

Levofloxacin 1.5.% FFP 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 Levofloxacin 1.5.% FFP is essentially constant (approximately 100 mg/mL). Levofloxacin 1.5.% FFP 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. Levofloxacin 1.5.% FFP 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.

Levofloxacin 1.5.% FFP dosage

Dosage in Adult Patients with Normal Renal Function

The usual dose of Levofloxacin 1.5.% FFP Tablets, USP 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 Levofloxacin 1.5.% FFP Tablets, USP 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 Levofloxacin 1.5.% FFP 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 Levofloxacin 1.5.% FFP 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

Levofloxacin 1.5.% FFP Tablets

Levofloxacin 1.5.% FFP Tablets, USP should be administered at least two hours before or two hours after antacids containing magnesium, aluminum, as well as sucralfate, metal cations such as iron, and multivitamin preparations with zinc or didanosine chewable/buffered tablets or the pediatric powder for oral solution.

Administration Instructions

Food and Levofloxacin 1.5.% FFP Tablets, USP

Levofloxacin 1.5.% FFP Tablets, USP can be administered without regard to food.

Hydration for Patients Receiving Levofloxacin 1.5.% FFP Tablets, USP

Adequate hydration of patients receiving oral Levofloxacin 1.5.% FFP Tablets, USP should be maintained to prevent the formation of highly concentrated urine. Crystalluria and cylindruria have been reported with quinolones.

Levofloxacin 1.5.% FFP interactions

See also:
What other drugs will affect Levofloxacin 1.5.% FFP?

There are no data concerning an interaction of quinolones IV with oral antacids, sucralfate, multivitamins, didanosine or metal cations. However, no quinolone should be co-administered with any solution containing multivalent cations eg, magnesium, through the same IV line.

Theophylline: No significant effect of Levofloxacin 1.5.% FFP on the plasma concentrations, AUC and other disposition parameters for theophylline was detected in a clinical study involving 14 healthy volunteers. Similarly, no apparent effect of theophylline on Levofloxacin 1.5.% FFP absorption and disposition was observed. However, concomitant administration of other quinolones with theophylline has resulted in prolonged elimination half-life, elevated serum theophylline levels and a subsequent increase in the risk of theophylline-related adverse reactions in the patient population. Therefore, theophylline levels should be closely monitored and appropriate dosage adjustments made when Levofloxacin 1.5.% FFP is co-administered. Adverse reactions, including seizures, may occur with or without an elevation in serum theophylline levels.

Warfarin: No significant effect of Levofloxacin 1.5.% FFP on the C_max, AUC and other disposition parameters for R- and S-warfarin was detected in a clinical study involving healthy volunteers. Similarly, no apparent effect of warfarin on Levofloxacin 1.5.% FFP absorption and disposition was observed. There have been reports during the postmarketing experience in patients that Levofloxacin 1.5.% FFP enhances the effects of warfarin. Elevations of the prothrombin time in the setting of concurrent warfarin and Levofloxacin 1.5.% FFP use have been associated with episodes of bleeding. Prothrombin time, INR or other suitable anticoagulation tests should be closely monitored if Levofloxacin 1.5.% FFP is administered concomitantly with warfarin. Patients should also be monitored for evidence of bleeding.

Cyclosporine: No significant effect of Levofloxacin 1.5.% FFP on the C_max, AUC and other disposition parameters for cyclosporine was detected in a clinical study involving healthy volunteers. However, elevated serum levels of cyclosporine have been reported in the patient population when co-administered with some other quinolones. Levofloxacin 1.5.% FFP C_max and k_e were slightly lower while T_max and t_½ were slightly longer in the presence of cyclosporine than those observed in other studies without concomitant medication. The differences, however, are not considered to be clinically significant. Therefore, no dosage adjustment is required for Levofloxacin 1.5.% FFP or cyclosporine when administered concomitantly.

Digoxin: No significant effect of Levofloxacin 1.5.% FFP on the C_max, AUC and other disposition parameters for digoxin was detected in a clinical study involving healthy volunteers. Levofloxacin 1.5.% FFP absorption and disposition kinetics were similar in the presence or absence of digoxin. Therefore, no dosage adjustment for Levofloxacin 1.5.% FFP or digoxin is required when administered concomitantly.

Probenecid and Cimetidine: No significant effect of probenecid or cimetidine on the rate and extent of Levofloxacin 1.5.% FFP absorption were observed in a clinical study involving healthy volunteers. The AUC and t_1/2 of Levofloxacin 1.5.% FFP were 27-38% and 30% higher, respectively, while CL/F and CL_R were 21-35% lower during concomitant treatment with probenecid or cimetidine compared to Levofloxacin 1.5.% FFP alone. Although these differences were statistically significant, the changes were not high enough to warrant dosage adjustment for Levofloxacin 1.5.% FFP when probenecid or cimetidine is co-administered.

Nonsteroidal Anti-Inflammatory Drugs: The concomitant administration of a nonsteroidal anti-inflammatory drug with a quinolone, including Levofloxacin 1.5.% FFP, may increase the risk of CNS stimulation and convulsive seizures.

Antidiabetic Agents: Disturbances of blood glucose, including hyperglycemia and hypoglycemia, have been reported in patients treated concomitantly with quinolones and an antidiabetic agent. 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 Levofloxacin 1.5.% FFP. Levofloxacin 1.5.% FFP should be infused slowly over 60 to 90 minutes, depending on dosage.

Crystalluria and cylindruria have been reported with quinolones, including Levofloxacin 1.5.% FFP. Therefore, adequate hydration of patients receiving Levofloxacin 1.5.% FFP 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 Levofloxacin 1.5.% FFP 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 Levofloxacin 1.5.% FFP for a wide variety of infectious diseases. Patients received Levofloxacin 1.5.% FFP 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 Levofloxacin 1.5.% FFP doses of 750 mg once daily, 250 mg once daily, and 500 mg once or twice daily. Discontinuation of Levofloxacin 1.5.% FFP 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 Levofloxacin 1.5.% FFP-treated patients and less common adverse reactions, occurring in 0.1 to <1% of Levofloxacin 1.5.% FFP-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 Levofloxacin 1.5.% FFP. 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 Levofloxacin 1.5.% FFP. 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.

Levofloxacin 1.5.% FFP contraindications

See also:
What is the most important information I should know about Levofloxacin 1.5.% FFP?

Patients hypersensitive to Levofloxacin 1.5.% FFP or any other quinolones or any excipients of Levofloxacin 1.5.% FFP. Patients with epilepsy and those with history of tendon disorder related to fluoroquinolone administration.

Use in pregnancy: Levofloxacin 1.5.% FFP 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, Levofloxacin 1.5.% FFP 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, Levofloxacin 1.5.% FFP 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 Levofloxacin 1.5.% FFP, cause arthropathy and osteochondrosis in juvenile animals of several species.

Use in

Elderly: The pharmacokinetic properties of Levofloxacin 1.5.% FFP in younger adults and elderly do not differ significantly when creatinine clearance is taken into consideration. However, since Levofloxacin 1.5.% FFP is known to be substantially excreted by the kidney, the risk of toxic reactions to Levofloxacin 1.5.% FFP 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.
