Levofloxacin (as hemihydrate).
Each mL contains Levofloxacin hemihydrate equivalent to Levofloxacin 5 mg.
Pharmacology: Pharmacodynamics: Levofloxacin is a Fluoroquinolone anti-infective agent which experts a broad spectrum potent anti-bacterial activity against organisms causing ophthalmological infections, including gram-positive bacteria, gram negative bacteria and anaerobic bacteria. Levofloxacin inhibits DNA synthesis in susceptible organisms via inhibition of type II topoisomerase (DNA gyrase) and topoisomerase IV.
Susceptible strains: Levofloxacin has been shown to be active against gram-positive and gram-negative bacteria such as: Gram-positive bacteria: Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus sp., Streptococcus group G, Streptococcus pneumoniae, α-hemolytic streptococci (viridans group), and Corynebacterium spp.
Gram-negative bacteria: Serratia marcescens, Haemophilus influenzae or parainfluenzae, Pseudomonas aeruginosa, Acinetobacter lwoffii, Moraxella sp., Klebsiella sp., Enterobacter sp., and Proteus sp.
Pharmacokinetics: After ocular instillation, Levofloxacin is well maintained in the tear-film.
Levofloxacin as the hemihydrates in eye drops is used for the treatment of bacterial blepharitis, dacryocystitis, hordeolum, conjunctivitis, tarsadenitis, keratitis (including corneal ulcer) caused by susceptible strains and aseptic treatment during a perioperative period for ocular surgery.
Adult: Instill 1 to 2 drops a time 3 times daily. The dosage may be adjusted according to the patient's symptoms.
Pediatric: Children ≥ 6 years of age and Adolescents: Refer to adult dosing.
Renal impairment: There are no dosage adjustments. However, dosage adjustment unlikely due to low systemic absorption.
Hepatic impairment: There are no dosage adjustments. However, dosage adjustment unlikely due to low systemic absorption.
Overdose and Treatment: After a local overdose with Levofloxacin eye drops, the eyes can be flushed with clean water at room temperature. Moreover, the total amount of levofloxacin in a bottle of eye drops is too small to induce toxic effects after an accidental oral intake.
This drug is contraindicated in patients who are hypersensitive to Levofloxacin, the ingredient of this product or any quinolone antibiotics.
(According to Notification of the Ministry of Public Health): 1. Do not use this product if the patient is hypersensitive to Levofloxacin or other quinolones.
2. If any symptoms such as eyelid redness/swelling, rash, muscle pain, tendinopathy are observed administration should be discontinued and consult the doctor immediately.
3. Levofloxacin may cause hepatotoxicity or renal toxicity.
Route of administration: Ophthalmic use only. Not for injection or subconjunctival injection or introduction directly into the anterior chamber.
Prolonged use of levofloxacin may result in overgrowth of non-susceptible organisms, including fungi. If superinfection occurs, Levofloxacin should be discontinued and other appropriate therapy instituted.
Pregnancy category: C.
The safety of this product during pregnancy has not been established. Should be used in pregnant women if the expected therapeutic benefits are judged to outweigh the possible risks associated with treatment.
Levofloxacin may be distributed into milk. Caution is advised if ophthalmic levofloxacin is administered in nursing women.

Specific drug interaction studies have not been conducted to date. However, since some systemic absorption may occur following topical application of Levofloxacin to the eye, the possibility of drug interactions such as those reported with systemic administration of some quinolone anti-infectives (eg. interactions with theophylline, caffeine, oral anticoagulants, cyclosporine) should be considered.
Store below 30°C. Protect from light.
