ofloxacin and Long QT Syndrome

ofloxacin has been researched along with Long QT Syndrome in 12 studies

Ofloxacin: A synthetic fluoroquinolone antibacterial agent that inhibits the supercoiling activity of bacterial DNA GYRASE, halting DNA REPLICATION.
9-fluoro-3-methyl-10-(4-methylpiperazin-1-yl)-7-oxo-2,3-dihydro-7H-[1,4]oxazino[2,3,4-ij]quinoline-6-carboxylic acid : An oxazinoquinoline that is 2,3-dihydro-7H-[1,4]oxazino[2,3,4-ij]quinolin-7-one substituted by methyl, carboxy, fluoro, and 4-methylpiperazin-1-yl groups at positions 3, 6, 9, and 10, respectively.
ofloxacin : A racemate comprising equimolar amounts of levofloxacin and dextrofloxacin. It is a synthetic fluoroquinolone antibacterial agent which inhibits the supercoiling activity of bacterial DNA gyrase, halting DNA replication.

Long QT Syndrome: A condition that is characterized by episodes of fainting (SYNCOPE) and varying degree of ventricular arrhythmia as indicated by the prolonged QT interval. The inherited forms are caused by mutation of genes encoding cardiac ion channel proteins. The two major forms are ROMANO-WARD SYNDROME and JERVELL-LANGE NIELSEN SYNDROME.
