Are cephalosporins resistant to penicillinase?

25 Penicillinase-resistant penicillins and first-generation cephalosporins are first-line choices for the treatment of skin and soft tissue infections, with macrolide antibiotics, amoxicillin-clavulanate, cefpodoxime and cefdinir as second-line agents.

Which penicillin is resistant to penicillinase?

How do penicillinase-resistant penicillins work?

The penicillinase-resistant penicillins resist the hydrolysis of the beta-lactam ring by the bacterial enzymes. They are active against most organisms that are susceptible to the natural penicillins (although less active than penicillin G) and have extended coverage against resistant forms.

What drug from penicillins is not destroyed by penicillinase?
