FeaturePain relief: from coal tar to paracetamol
Analgesics, ie pain-relieving drugs, fall into two categories: those that also reduce body temperature in fevers (antipyretics), and those that act mainly on the brain - typically morphine and diamorphine/heroin. Here we consider members of the first group, particularly those once designated 'coal tar analgesics'. Paracetamol, our most popular over-the-counter pain killer, is one of these.
