Answer

Fluoroquinolones

Fluoroquinolones inhibit bacterial DNA synthesis and, consequently, growth by inhibiting DNA gyrase and topoisomerases, which are required for replication, transcription, and translation of genetic material. The use of fluoroquinolones is not recommended in patients with myasthenia gravis.

Second-generation fluoroquinolones, such as gatifloxacin and moxifloxacin, have excellent cerebrospinal fluid (CSF) penetration, and animal models suggest that they are effective in penicillin- and ceftriaxone-resistant pneumococcal meningitis. (Clinical trial data are available only for trovafloxacin, which has been removed from the market.)

Ciprofloxacin (Cipro, Cipro XR)

Quinolones have broad activity against gram-positive and gram-negative aerobic organisms. Ciprofloxacin has no activity against anaerobes. Ciprofloxacin has an off-label indication for prophylaxis against Neisseria meningitidis meningitis after close contact with an infected person.

Moxifloxacin (Avelox)

Quinolones have broad activity against gram-positive and gram-negative aerobic organisms. Infectious Diseases Society of America guidelines recommend moxifloxacin plus vancomycin as an alternative to third-generation cephalosporins in meningitis caused by penicillin- and ceftriaxone-resistant S pneumoniae strains.
