Drugs

Muhtasari

When you take medicine for a sore throat or a chest infection, you are putting a drug into your body to change what is happening inside it. Some of the most important medicines ever discovered are antibiotics, which kill the bacteria that cause infections, but their power is under threat.

In this lesson you will learn what a drug is, how antibiotics treat bacterial infections, why they do nothing against viruses, and how antibiotic resistance develops. You will also see why doctors now urge us to use antibiotics only when they are truly needed.
