Mechanism of Action Amoxicillin is similar to penicillin in its bactericidal action against susceptible bacteria during the stage of active multiplication. It acts through the inhibition of cell wall biosynthesis that leads to the death of the bacteria.
Why is it important to understand the mechanisms of these medications?
Knowledge of a drug’s mechanism of action enables better dosing through monitoring of the drug’s effects on the target pathway in the patient. For example, the proper statin dosage for a given patient is often determined on the basis of the observed reduction in blood cholesterol levels.
