Drug resistance in hospitals and clinics is a big challenge. It makes some treatments not work as well, and in some cases, they might even fail completely. Let's look at some important reasons why this happens:
Genetic Changes: Bacteria and cancer cells can change their genes. This can affect how drugs work on them. For example, changes in a specific gene can make certain medications useless against infections.
Drug Pumps: Some cells have special pumps that push drugs out of the cell. This happens faster than the drugs can do their job. A well-known example is a pump called P-glycoprotein, which helps cancer cells get rid of chemotherapy drugs.
Target Changes: Some germs can change their drug targets, which makes it harder for the drugs to attach and work. A common example is MRSA, a type of bacteria that changes parts of its structure to avoid the effects of penicillin.
Changed Metabolism: Some cancer cells can change how they use energy. This helps them survive when drugs are trying to kill them. For example, they might produce more enzymes that break down and neutralize chemotherapy drugs.
Knowing about these reasons is very important. It can help doctors come up with better ways to deal with drug resistance and improve treatment success for patients.
