<prompt> True about clavulanic acid is?b lactamase inhibitorsExtended spectrum penicillinGram negative bacteriaPlasmid inhibitors  <response>: ANSWER: A b lactamase inhibitorsREF: Katzung 9th ed p. 1064Beta-Lactamase Inhibitors Clavulanic Acid, Sulbactam, Tazobactam? These substances resemble -lactam molecules but themselves have very weak antibacterial action. They are potent inhibitors of many but not all bacterial lactamases and can protect hydrolyzable penicillins from inactivation by these enzymes.? The indications for penicillin- -lactamase inhibitor combinations are empirical therapy for infections caused by a wide range of potential pathogens in both immunocompromised and immunocompetent patients and treatment of mixed aerobic and anaerobic infections, such as intraabdominal infections.? Clavulanic acid or clavulanate, usually combined Kith amoxicillin Augmentin or ticarcillin? Sulbactam, usually combined with ampicdlin? Tazobactam, usually combined with piperacillin
