4.3.1.8 Antibiotics and painkillers Students should be able to explain the use of antibiotics and other medicines in treating disease. Antibiotics, such as penicillin, are medicines that help to cure bacterial disease by killing infective bacteria inside the body. It is important that specific bacteria should be treated by specific antibiotics. The use of antibiotics has greatly reduced deaths from infectious bacterial diseases. However, the emergence of strains resistant to antibiotics is of great concern. Antibiotics cannot kill viral pathogens. Painkillers and other medicines are used to treat the symptoms of disease but do not kill pathogens. It is difficult to develop drugs that kill viruses without also damaging the body’s tissues. 1 Describe the action of antibiotics. Explain how antibiotics and painkillers are used to treat disease. Examine data, ie on how the use of antibiotics has reduced infectious diseases and summarise the information. Describe the problems of antibiotic resistance and how it can be reduced. Calculate how many bacteria there will be in 10 hours if they double in number every 30 minutes. Describe what would happen to the population of bacteria if antibiotics were taken. Demonstrate how antibiotic resistant strains can survive antibiotics by using balloons of one colour to represent normal bacteria, and a balloon of a different colour to represent the resistant strain. Demonstrate the action of antibiotics (a pin) on the normal balloons. Demonstrate a virus using a ball that cannot be popped with the pin. Demonstrate painkillers using a marker pen – bacteria can be affected by it, but cannot be destroyed by them. Students can investigate how not completing the course of antibiotics can allow reinfection to occur. Add a set number of drops of vinegar (the antibiotics course) into a test tube of water and phenolphthalein
