Summary

  • Paracetamol is used to relieve minor aches and pains such as a headache.

  • The body treats paracetamol as a chemical it needs to get rid of.

  • Most medicines are fat-soluble - which favours their absorption from the gastrointestinal tract. The body must make it more water-soluble to promote excretion in urine. This is where metabolism comes in.

  • A pharmacologist needs to understand how paracetamol is metabolised to advise on proper prescribing.
