Tosufloxacin is a fluoroquinolone antibiotic used primarily for the treatment of bacterial infections, including respiratory tract, urinary tract, and skin infections. While it has been approved and used in Japan and several Asian countries, it is not approved in Europe or the United States due to safety concerns related to toxicity.
Pharmacokinetics
Pharmacokinetic parameters reported in healthy adult subjects after oral administration of a single 150 mg dose of tosufloxacin.
