How does antibiotics work?

You must have already felt that sore throat that does not go away, with fever and malaise, which increases. Suddenly, you can't swallow anything right, it hurts a lot and the solution… is the doctor! Soon, he examines and gives the sentence: – We will have to use an antibiotic. Then you think: – What is this medicine? How will he cure me?

The word “antibiotic” comes from the Greek and means “against a living being”, in this case, against bacteria and other microorganisms. This medicine can be produced from plants, fungi and even disease-causing bacteria. In the laboratory, they go through chemical processes that turn the potential to cause disease into that of fighting the microorganisms that are causing the infection.

To work, the antibiotic enters the bloodstream. Yes, it is the blood that transports the medicine to the affected area so that it starts to fight or neutralize the action of the micro-organism that caused the disease. The antibiotic destroys the structure of the bacteria, preventing them from multiplying. Like? A large part of this drug works by destroying the plasma membrane of bacteria and without this protection they cannot resist.

But it is good to be careful: antibiotics are a type of medication that cannot be used without the doctor being sure that the problem really requires his recommendation. This is for two reasons: antibiotics are strong medicines that fight infection-causing microorganisms, but they can also destroy microorganisms that are allies of our health, such as some bacteria that help our health. digestion; another reason is that the continued use of this drug can make disease-causing microorganisms resistant to it, and then the antibiotic no longer works.
