The aim of Martindale is to provide healthcare professionals with unbiased evaluated information on drugs and medicines used throughout the world. It therefore has to develop as the body of knowledge on existing drugs grows, new drugs emerge, new preparations are launched, and old preparations are abandoned, reformulated, or redefined. It also has to reflect the changing needs of those practising pharmacy and medicine.

Our aim is to evaluate the literature, covering important studies, guidelines, and useful reviews and place them in context. Multicentre studies, meta-analyses, and systematic reviews play an important role in the study of drug treatment, and their findings and conclusions are considered in many of our chapters. However, there is also a place for the anecdotal report and the small study, and information from such sources is included where appropriate. Acknowledgement is also given to information referenced from a number of authoritative sources including the British National Formulary, the British National Formulary for Children, the British Pharmacopoeia, the European Pharmacopoeia, the United States National Formulary, and the United States Pharmacopeia.

Inclusion in Martindale of a substance or a preparation is not to be considered as a recommendation for use, nor does it confer any status on the substance or preparation. While considerable efforts have been made to check the material in Martindale, the publisher cannot accept any responsibility for errors and omissions. Also the reader is assumed to possess the necessary knowledge to interpret the information that Martindale provides.

Martindale contains information on drugs in clinical use worldwide, as well as selected investigational and veterinary drugs, herbal and complementary medicines, pharmaceutical excipients, vitamins and nutritional agents, vaccines, radiopharmaceuticals, contrast media and diagnostic agents, medicinal gases, drugs of abuse and recreational drugs, toxic substances, disinfectants, and pesticides.

The information on drugs and other substances is arranged into monographs that summarise the nomenclature, properties, and actions. Sections of text summarise the relevant information, notably for licensed uses, followed, if appropriate, by referenced abstracts or reviews that expand upon the details given in the text or add additional information.

Preparations summaries of more than 149,000 proprietary products from 36 countries are included. Information is provided on proprietory name, manufacturer or distrubutor, country of origin, active ingredients, and a summary of the indications as given by the manufacturer. Cross-references link each ingredient to an appropriate drug monograph where possible. Links are also provided to contact details for manufacturers.

In addition, more than 660 disease treatment reviews offer overviews of the diseases and drugs used in their treatment, along with key references. Cross-references are provided between disease reviews and relevant drug monographs.
