Drug Interactions

Increased concentration of ciclosporin or tacrolimus. Reduced absorption with didanosine, ferrous sulfate or dietary supplements containing zinc, calcium, magnesium or iron. May increase plasma levels of theophylline. Increased risk of tendon rupture with corticosteroids. Reduced absorption with sucralfate and antacids containing magnesium and aluminium; administer at least 2 hr before or 2 hr after antacids. Increased half-life and decreased clearance of procainamide. Altered glucose levels with antidiabetic agents (e.g. insulin, glyburide). Potentially Fatal: Increased risks of ventricular arrhythmias with QT prolonging drugs e.g. class IA (quinidine, procainamide) or class III (amiodarone, sotalol) antiarrhythmics, fluoxetine, imipramine. Increased risk of CNS stimulation and seizures with NSAIDs. Increased prothrombin time with warfarin.

Contraindications

Hypersensitivity to levofloxacin or other quinolones. Child <18 yr.

Mechanism of Action

Levofloxacin exerts antibacterial action by inhibiting bacterial topoisomerase IV and DNA gyrase, the enzymes required for DNA replication, transcription repair and recombination. It has in vitro activity against a wide range of gram-negative and gram-positive microorganisms. Absorption: Rapid and complete absorption from the GIT (oral); peak plasma concentrations within 1-2 hr. Distribution: Widely distributed in bronchial mucosa, lungs; CSF (relatively poor). Protein-binding: 30-40%. Metabolism: Limited. Excretion: Mainly via urine (largely as unchanged drug); 6-8 hr (elimination half-life).

Special Precautions

Known or suspected CNS disorders (e.g. severe cerebral arteriosclerosis, epilepsy) or other risk factors that predispose to seizures. Avoid unnecessary exposure to sunlight or artificial UV light. History of prolonged QT interval, uncorrected electrolyte disturbances. DM (carefully monitor blood glucose levels). Periodically monitor renal, hepatic and haematopoietic functions during treatment. Pregnancy and lactation. Elderly. May impair ability to drive or operate machinery.
