Aspirin, like ibuprofen, is an NSAID.
Whilst categorised as a painkiller, it is not usually used to relieve pain.
Codeine is a type of painkiller that works more effectively when combined with paracetamol in a single pill advises the NHS.
This pill, known as co-codamol, can be purchased over the counter in pharmacies and, like aspirin, is not recommended for long term use.
