Question
How tazobactam is superior than sulbactam? Please send with some clinical trials and examples.
Answer
Structurally, tazobactam is a sulbactam derivative that has demonstrated highly potent activity against staphylococcal penicillinase, extended-spectrum betalactamases and type II, III, IV and V -betalactamases of the Richmond & Sykes classification.
In general, sulbactam, clavulanate, and tazobactam are all potent inhibitors of staphylococcal penicillinase; chromosomal beta-lactamases produced by Bacteroides species, Proteus vulgaris, Haemophilus influenzae, Neisseria gonorrhoeae; and type IV enzymes of Klebsiella species. Although sulbactam possesses activity against TEM-1 and TEM-2 beta-lactamases, it does not have reliable activity against SHV-1 beta-lactamases. Clavulanate and tazobactam are potent inhibitors of both TEM and SHV-1 beta-lactamases. P. aeruginosa and some Enterobacteriaceae produce an inducible, extremely potent, broad-spectrum enzyme (type I beta-lactamase). Tazobactam is the only currently available. beta-lactamase inhibitor with activity against type I beta-lactamases; however, some enzymes are not inhibited by tazobactam.
