Ampicillin belongs to a group of beta-lactam antibiotics. It is classified as critically important human medicine by WHO. Ampicillin is one of the synthetic derivatives of penicillin. It was generated by adding an amino group side chain on penicillin. Ampicillin inhibits the synthesis of the bacterial cell wall by stopping the peptidoglycan cross-linking. It is effective against both gram-positive and gram-negative bacteria.
