Answer

Penicillins, Extended-Spectrum

Extended-spectrum, or fourth-generation, penicillins are semisynthetic modifications of natural penicillin that have an extended spectrum of activity, particularly against gram-negative bacteria such as Pseudomonas, Enterobacter, Proteus, and Klebsiella species.

Piperacillin and tazobactam (Zosyn)

Piperacillin-tazobactam is a semisynthetic penicillin with an increased spectrum against gram-negative bacilli. The addition of tazobactam inhibits beta-lactamases produced by bacteria. It is a broad-spectrum drug for gram-positive, gram-negative, and anaerobic bacteria; it covers most gram-positive organisms except MRSA.
