block nerve impulses communicating to the brain + pain
bring down an elevated temperature
No effect on viruses
Don't cure faster - have to wait for immune system to overcome pathogen
e.g. paracetamol, aspirin, calpol
Antibiotics:
Work inside body + destroy pathogens
First became available in 1940s
damage bacterial cells without harming other cells
Some kill a wide range of bacteria
can't kill viruses
strains of bacteria that are becoming antibiotic resistant to antibiotics are evolving
have to finish the course of antibiotics to kill all the bacteria
e.g. penicillin
Can Antibiotics kill viral pathogens?
They have no effect on viral diseases as they reproduce inside the cells of your body. It's extremely difficult to develop drugs that will kill the virus without damaging the cells/ tissues of body aswell
Explain how strains of antibiotic resistant bacteria are evolving?
