Yes they are

1. Elaboration of a beta-lactamase by the organism induces enzymatic beta lactam hydrolysis.

2. Mutation of PBP (penicillin binding protein) prevents binding.

3. Mutation of porin proteins prevents access of the beta lactam into the cell wall.

it's amoxicillin 875mg and clauvulanic acid 125mg, aka Augmentin. the clauvulanic acid binds up bacterial penicillin binding proteins and allows the amoxicillin to work in most penicillin-resistant bacteria.
