Oral Antibiotics

Oral antibiotics are used to treat severe infection or cellulitis. Fluoroquinolones are the drugs of choice by virtue of their coverage of Pseudomonas species.

Ciprofloxacin (Cipro)

Ciprofloxacin is a fluoroquinolone that inhibits bacterial DNA synthesis (and thus growth) by inhibiting DNA gyrase and topoisomerases, which are required for replication, transcription, and translation of genetic material. It has activity against pseudomonads, streptococci, MRSA, S epidermidis, and most gram-negative organisms but not against anaerobes.
