Appendix hThe World Health Organization model list of essential drugs

We reprint the current list (by permission). Whilst the WHO programme (revised 1999) was instituted particularly to help less developed countries, the list has interest and lessons for all societies facing, as they now are, the problems of delivering economically affordable health care to all. We commend a study of the list to our readers (see also p. 18).

The list of essential drugs may be considered against the background of the available marketed medicines worldwide. Any national or local group of health workers wishing to produce a formulary to provide for the needs of their own community would be well advised to study the current version in addition to other sources.

A major standard reference work (Martindale 1996 The extra pharmacopoeia. 31st edn., Pharmaceutical Press, London), describes 62500 preparations or groups of preparations from 17 different countries.

Explanatory notes

We print the list in full.

Drugs marked* represent an example of a therapeutic group, i.e. various other drugs could serve as an alternative say, on cost grounds.

Complementary drugs are for use where, for any reason, drugs in the main list are unavailable, or there are exceptional medical circumstances, e.g. bacterial resistance, rare disorders.

Spelling of drug names. The World Health Organization devises recommended International Nonproprietary Names (rINN). These are becoming universal; most do not give rise to any confusion, but occasionally we insert an alternative name or spelling.

Not every entry in the list is discussed in this book. Conversely, the book may give drug treatments for specific conditions that differ from those listed here.

Blood Pressure Health

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
