Topical antibacterials are being reviewed with special emphasis on their spectrum of activity, resistance patterns, contact sensitivity potential and clinical uses. Factors which help the physician to choose a particular antibacterial for the specific indication in order to have the maximum efficacy and minimum adverse effects are discussed.
