Moxifloxacin is a fluoroquinolone antibiotic. Oral formulations of medicines containing moxifloxacin are authorised at the level of the Member States in the European Union (EU) under several trade names for the treatment of acute exacerbation of chronic bronchitis, community-acquired pneumonia, acute bacterial sinusitis and, in some Member States, for mild to moderate pelvic inflammatory disease.
The EMEA's Committee for Medicinal Products for Human Use (CHMP) has reviewed all available information on the safety of moxifloxacin-containing medicines for oral use, following concerns over their liver safety when used for acute bacterial sinusitis, acute exacerbation of chronic bronchitis and community-acquired pneumonia.
At its July 2008 meeting, the CHMP concluded that the benefits of oral moxifloxacin medicines continue to outweigh its risks. However, due to safety concerns, mainly related to an increased risk of adverse hepatic reactions, the CHMP recommended restricting their use in these indications. For acute bacterial sinusitis and acute exacerbations of chronic bronchitis, they should only be prescribed when other antibiotics cannot be used or have failed. For community acquired pneumonia, they should only be given when treatment with other antibiotics cannot be used.
The CHMP also recommended that the warnings of oral moxifloxacin-containing medicines should be strengthened concerning the risk of diarrhoea, heart failure in women and older patients, severe skin reactions and fatal liver injury.
Doctors are advised to prescribe oral moxifloxacin-containing medicines according to the updated product information and to consider the official guidance on the appropriate use of the antibiotics and the local prevalence of resistance. Patients should speak to their doctor or pharmacist if they have any questions.
The CHMP opinion will now be forwarded to the European Commission for the adoption of a decision applicable to all oral moxifloxacin-contain medicines authorised in the EU.
