The publishing division of the Royal Pharmaceutical Society, the Pharmaceutical Press, has published a new version of their renown Martindale, which they name ‘the Complete Drug Reference’. The content of the printed version is also available on-line, but for a separate fee through ‘MedicinesComplete’ (www.medicinescomplete.com). The first printed version of the book appeared in 1833. Despite the rapidly changing world of pharmaceuticals, Martindale continues to be internationally recognized as the reference for pharmacists in most areas of practice and research. In this version (37th edition) major changes are again made to ensure that the resource continues to meet needs of practitioners, researchers and academics.
