There is a tactic in working of amoxicillin to kill bacteria from our body and prevent the entering of further in the form of antigens. Let’s have a look at the stages of its functioning:

  • The first step is penetration in which amoxicillin penetrates the bacterial cell wall to enter the body of bacteria.
  • Next is inhibition in which amoxicillin inhibits all the processes and functioning in the bacterial cell. For this process, one enzyme is involved called transpeptidase. That creates cross-linking between the molecules of peptidoglycan.
  • Then comes the phase of weakening, in which amoxicillin prevents the formation of the new cell wall in bacteria, and makes the previous one weaker and permeable.
  • Next starts the process of returning, In this phase cell wall of bacteria couldn’t withstand further pressure from outside and ruptures. Due to this all the content present in the cell leaks which leads to the death of the bacterial cell.
  • The last phase of amoxicillin action is elimination, in this phase as bacteria is died immune system of the human body removes it from the body.

In this way, bacteria get died and our body starts to recover from that infection because no other bacteria act to spoil it further.
