(verify) pharmacodynamics 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. it functions by inhibiting the action of dna-gyrase, preventing bacterial cells from reproducing or repairing themselves, resulting in cellular death. side effects 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.
