How does ampicillin work?.
Ampicillin belongs to the pencillin group of drugs and is effective against gram-positive as well as some gram-negative bacteria. It differs from pencillin with the presence of an amino group, which makes it effective against the gram-negative bacteria as well. Ampicillin inhibits the action of the enzyme transpeptidase, which is necessary to create bacterial cell walls. The bacteria are killed because of no formation of the cell wall.
Ampicillin’s mode of action is very similar to Penicillin and it works by stopping the bacteria from growing. This is achieved by impairing the bacteria’s ability to form bonds and thereby pulling down their cell walls. The holes that appear in the cell walls allow the body’s immune system to take over and fight off the bacteria. Ampicillin has received FDA approval for its action of mechanism.
