Gemifloxacin (GFX)

Gemifloxacin mesylate is an oral broad-spectrum quinolone antibacterial agent used in the treatment of acute bacterial exacerbation of chronic bronchitis and mild-to-moderate pneumonia. Fluoroquinolones are generally well tolerated with most side effects being mild and serious adverse effects being rarely. Some of the serious adverse effects which occur more commonly with fluoroquinolones than with other antibiotic drug classes include CNS and tendon toxicity. The serious events may occur with therapeutic or with acute overdose. At therapeutic doses they include: central nervous system toxicity, cardiovascular toxicity, tendon / articular toxicity, and rarely hepatic toxicity. Events that may occur in acute overdose are rare and include: renal failure and seizure. Children and the elderly are at greater risk. Tendon damage may manifest during, as well as up to a year after fluoroquinolone therapy.
