Beta lactam antibiotics

1. Cephalosporins – Ceftriaxone (3rd generation cephalosporin)
2. Penicillins – Piperacillin, Amoxycillin 
3. Monobactam – Aztreonam
4. Carbapenems – Meropenem

Beta Lactamase Inhibitor –

• These drugs inhibit the action of beta-lactamase enzymes, which are produced by certain bacteria to inactivate beta-lactam antibiotics (like penicillins and cephalosporins). 

• By inhibiting these enzymes, beta-lactamase inhibitors help restore the effectiveness of beta-lactam antibiotics against resistant bacteria.

• Examples- Clavulanic acid, Sulbactam, Tazobactam.
