What is the dosing for moxifloxacin as described?

• A. 400 mg IV daily
• B. 400 mg PO twice daily
• C. 400 mg PO daily
• D. 200 mg PO daily

Answer: (A)

Moxifloxacin is a fluoroquinolone with a long half-life and good tissue penetration, which supports once-daily dosing to maintain effective levels. In this protocol, the regimen uses 400 mg given by IV once daily, providing rapid and reliable concentrations when immediate effect is needed or when the patient cannot take medications by mouth. The 400 mg IV daily dose is the standard described, aligning with the drug’s established efficacy at that level. The other options—lower doses or different frequencies or routes—do not match the described regimen, which specifically calls for 400 mg IV daily.
