Balofloxacin (INN) is a fluoroquinolone antibiotic. It is sold under the brand name Q-Roxin in Korea, and under various names in India.[1] It is not approved by the FDA for use in the United States.
Balofloxacin is a fluoroquinolone that has a broad spectrum in vitro activity against a wide range of Gram-positive and Gram-negative bacteria, with enhanced activity against Gram positive bacteria, including MRSA and Streptococcus pneumoniae.[2] It functions by inhibiting the action of DNA-gyrase, preventing bacterial cells from reproducing or repairing themselves, resulting in cellular death.[3]
Vomiting, headache, dizziness, stomach pain, nausea, diarrhea and decreased liver function are the most common side effects. In rare cases, Balofloxacin can lead to or worsen tendinitis, and muscular damage.
