Grepafloxacin hydrochloride (trade name Raxar, Glaxo Wellcome) was an oral broad-spectrum fluoroquinolone antibacterial agent used to treat bacterial infections. Grepafloxacin was withdrawn world wide from markets in 1999,[1][2] owing to its side effect of lengthening the QT interval on the electrocardiogram, leading to cardiac events and sudden death.[3]

Clinical uses[edit]

Grepafloxacin was used for treating exacerbations of chronic bronchitis caused by susceptible bacteria (e.g. Haemophilus influenzae, Streptococcus pneumoniae, Moraxella catarrhalis),[4][5][6] community-acquired pneumonia (including those, in addition to the above germs, caused by Mycoplasma pneumoniae)[7][8] gonorrhea and non-gonococcal urethritis and cervicitis (for example caused by Chlamydia trachomatis or Ureaplasma urealyticum).[9][10]
