An analgesic (colloquially known as painkillers) is any member of the diverse group of drugs used to relieve pain and to achieve analgesia.

This derives from Greek an-, "without", and -algia, "pain".

Analgesic drugs act in various ways on the peripheral and central nervous system; they include paracetamol (acetaminophen), the nonsteroidal anti-inflammatory drugs (NSAIDs) such as the salicylates, narcotic drugs such as morphine, synthetic drugs with narcotic properties such as tramadol, and various others.
