How it works

This product’s leaflet is published as a scanned document. This section quotes the US prescribing label for the same active substance (levofloxacin). It describes the substance, not this Bulgarian product — its uses and doses can differ.

Levofloxacin is a member of the fluoroquinolone class of antibacterial agents [ see Microbiology (12.4)].

Half-life6–8 h
Mostly cleared after≈ 35 hfive half-lives — our arithmetic
How the body breaks it down

Due to the limited extent of levofloxacin metabolism, the pharmacokinetics of levofloxacin are not expected to be affected by hepatic impairment [see Use in Specific Populations ( 8.7 )].

How it leaves the body

Levofloxacin undergoes limited metabolism in humans and is primarily excreted as unchanged drug in the urine.

With food

Oral administration of a 500 mg dose of levofloxacinwith food prolongs the time to peak concentration by approximately 1 hour and decreases the peak concentration by approximately 14% following tablet and approximately 25% following oral solution administration.
