    Nafcillin is a beta-lactamase-resistant drug of the penicillin class.
    Mechanism of Actionβ-lactams interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to β-lactams is commonly due to cells containing plasmid encoded β-lactamases.
    SpectrumNafcillin is targets primarily gram-positive bacteria including Staphylococcus and Streptococcus species.
