Penicillin G works by interfering with the cell wall synthesis, resulting in cell wall exposure. This causes bacteria death. Penicillins are only bactericidal and do not work against viral infections. Penicillin G is mainly effective against Gram-negative organisms such as Neisseria gonorrhoeae and Neisseria meningitidi.
