Patients who have moderate clinical impairment or comorbid illnesses are best treated with parenteral agents and, unless a particular agent is strongly suspected, broad coverage should be afforded. Regimens for this use include a macrolide plus a second- or third-generation cephalosporin, (as single agents) ampicillin and sulbactam (Unasyn), piperacillin and tazobactam (Zosyn), or ticarcillin and clavulanate (Timentin).
