Are cephalosporins penicillinase resistant?
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.

Penicillinase-resistant penicillins (also referred to as second-generation penicillins) are antibiotics that are resistant to the bacterial enzyme beta-lactamase and are used to treat staphylococcal and streptococcal bacterial infections.
Is vancomycin resistant to penicillinase?
Vancomycin Resistance Specifically, vancomycin is used for resistant bacteria where other options such as beta-lactams are not effective. One such type of resistant bacteria where vancomycin is used are those that are resistant to methicillin, a type of penicillin.
What are extended-spectrum cephalosporins?
