How Levofloxacina Mylan works

Levofloxacina Mylan, like other fluoroquinolone antibiotics, exerts its antimicrobial activity via the inhibition of two key bacterial enzymes: DNA gyrase and topoisomerase IV. Both targets are type II topoisomerases, but have unique functions within the bacterial cell. DNA gyrase is an enzyme found only in bacteria that introduces negative supercoils into DNA during replication - this helps to relieve torsional strain caused by the introduction of positive supercoils during replication, and these negative supercoils are essential for chromosome condensation and the promotion of transcription initiation. It is comprised of four subunits (two A subunits and two B subunits) of which the A subunits appear to be the target of fluoroquinolone antibiotics. Bacterial topoisomerase IV, in addition to contributing to the relaxation of positive supercoils, is essential at the terminal stages of DNA replication and functions to “unlink” newly replicated chromosomes to allow for the completion of cell division.

Inhibition of these enzymes by levofloxacin likely occurs via complexation with the topoisomerase enzymes. The end result is a blockade of DNA replication, thus inhibiting cell division and resulting in cell death.

Administration of Levofloxacina Mylan (solution for infusion) should be continued for a minimum of 48 to 72 hours after the patient has become febrile or evidence of bacterial eradication has been obtained. Levofloxacina Mylan solution for infusion is only intended for slow intravenous infusion; it is administered once or twice daily. The infusion time must be at least 30 minutes for 250 mg or 60 minutes for 500 mg Levofloxacina Mylan solution for infusion. It is possible to switch from an initial intravenous application to the oral route at the same dosage after a few days.

Side Effects

The most frequently reported adverse events were headache and a taste disturbance following instillation. Other adverse events included decreased/blurred vision, diarrhea, dyspepsia, fever, infection, instillation site irritation/discomfort, ocular infection, nausea, ocular pain/discomfort, and throat irritation.

Toxicity

The LD₅₀ following oral administration in mice and rats is 1803 mg/kg and 1478 mg/kg, respectively.

Levofloxacina Mylan exhibits low potential for acute toxicity - following a single high dose of levofloxacin in several different test animals (e.g. mice, rats, monkeys) observed symptoms included ataxia, ptosis, decreased motor activity, dyspnea, tremors, and convulsions. Treatment of acute overdosage should involve stomach emptying (e.g. with activated charcoal) and general supportive measures. Consider monitoring of the patient's ECG to ensure QTc values remain within range. Levofloxacina Mylan is not efficiently removed by dialysis (peritoneal or hemodialysis) and is therefore of little benefit in cases of overdose.

Precaution

The following measures should be taken during administration of Levofloxacina Mylan: While taking Levofloxacina Mylan adequate amount of water should be drunk to avoid risk of crystalluria. Dose adjustment should be exercised during Levofloxacina Mylan ingestion in presence of renal insufficiency & hepatic insufficiency.

While taking Levofloxacina Mylan adequate amount of water should be drunk to avoid risk of crystalluria. Dose adjustment should be exercised during Levofloxacina Mylan ingestion in presence of renal insufficiency & hepatic insufficiency.

Infusion of fluid should be immediately discontinued if rigor arises for any reason during the process. Do not use if the solution is cloudy, contains particles or after expiry date.

If an allergic reaction to levofloxacin occurs, discontinue the drug. Serious acute hypersensitivity reactions may require immediate emergency treatment. Oxygen and airway management should be administered as clinically indicated.

Prolonged use may result in overgrowth of non-susceptible organisms, including fungi. If superinfection occurs, discontinue use and institute alternative therapy. Patients should be advised not to wear contact lenses if they have signs and symptoms of corneal ulcer. Avoid contaminating the applicator tip with material from the eye, fingers or other source.

Interaction

Specific drug interaction studies have not been conducted with this drug. However, the systemic administration of some quinolones has been shown to elevate plasma concentrations of theophylline, interfere with the metabolism of caffeine, and enhance the effects of the oral anticoagulant warfarin and its derivatives, and has been associated with transient elevations in serum creatinine in patients receiving systemic cyclosporine concomitantly.

Food Interaction

• Take with or without food. Food slightly alters kinetics but not to any clinically significant extent.

[Moderate] ADJUST DOSING INTERVAL: Food may reduce the oral absorption and bioavailability of levofloxacin.

According to the drug product labeling, administration of levofloxacin 500 mg with food prolonged the time to peak concentration by 1 hour and decreased the Cmax decreased by 25% following administration of the oral solution and by 14% following administration of the oral tablet.

MANAGEMENT: To ensure maximal and consistent oral absorption, levofloxacin oral solution should be taken at least one hour before or two hours after meals.

For administration of the oral solution with continuous enteral nutrition, some experts recommend that the tube feeding should be interrupted for one hour before and two hours after the dose of levofloxacin.

The oral tablets may be taken without regard to food.

Levofloxacina Mylan 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

Volume of Distribution

Levofloxacina Mylan is widely distributed in the body, with an average volume of distribution following oral administration between 1.09-1.26 L/kg (~89-112 L). Concentrations in many tissues and fluids may exceed those observed in plasma. Levofloxacina Mylan is known to penetrate well into skin tissue, fluids (e.g. blisters), lung tissue, and prostatic tissue, amongst others.

Elimination Route

Absorption of levofloxacin following oral administration is rapid and essentially complete, with an oral bioavailability of approximately 99%. Due to its nearly complete absorption, the intravenous and oral formulations of levofloxacin may be interchangeable. The T_max is generally attained 1-2 hours following administration and the C_max is proportional to the given dose - an intravenous dose of 500mg infused over 60 minutes resulted in a C_max of 6.2 ± 1.0 µg/mL whereas a 750mg dose infused over 90 minutes resulted in a C_max of 11.5 ± 4.0 µg/mL. Oral administration with food prolongs the T_max by approximately 1 hour and slightly decreases the C_max, but these changes are not likely to be clinically significant.

Systemic absorption following oral inhalation is approximately 50% lower than that observed following oral administration.

Half Life

The average terminal elimination half-life of levofloxacin is 6-8 hours.

Clearance

The average apparent total body clearance of levofloxacin ranges from 8.64-13.56 L/h, and its renal clearance ranges from 5.76-8.52 L/h. The relative similarity of these ranges indicates a small degree of non-renal clearance.

Elimination Route

The majority of administered levofloxacin is excreted unchanged in the urine. Following the administration of a single oral dose of levofloxacin, approximately 87% was eliminated unchanged in the urine within 48 hours and less than 4% was eliminated in the feces within 72 hours.

Pregnancy & Breastfeeding use

Levofloxacina Mylan is not recommended for use during pregnancy or nursing, as the effects on the unborn child or nursing infant are unknown.

Contraindication

Levofloxacina Mylan is contraindicated in patients with a history of hypersensitivity to Levofloxacina Mylan, quinolone antimicrobial agents, or any other components of this product.
