The setting of global standards isrequested in Article 2 of the WHO Constitution, which cites as one of the Organization s functions that it should develop, establish and promote inter-national standards with respect to food, biological, pharmaceutical and similarproducts.

6 Every government allocates a substantial proportion of its total healthbudget to medicines. This proportion tends to be greatest in developing countries, where it may exceed 40%.Without assurance that these medicines are relevant to priority health needsand that they meet acceptable standards of Quality , safety and efficacy, any healthservice is evidently compromised. In developing countries considerable admin-istrative and technical effort is directed to ensuring that patients receive effectivemedicines of good Quality . It is crucial to the objective of health for all that a reli-able system of medicines control be brought within the reach of every supply of essential medicines of good Quality was identified as one ofthe prerequisites for the delivery of health care at the International Conferenceon Primary Health Care in Alma-Ata in 1978.

7 Similarly, the Conference ofExperts on the Rational Use of Drugs, held in Nairobi in 1985, and WHO sRevised Drug Strategy, adopted by the World Health Assembly in May 1986,identified the effective functioning of national drug regulation and controlsystems as the only means to assure safety and Quality of medicines. Yet theWorld Health Assembly continues to express great concern about the Quality ,safety and efficacy of medicines, particularly those products or active pharma-ceutical substances imported into, or produced in, developing countries. Inrecent years counterfeit products have infiltrated certain markets in disquietingproportions.

8 Since the founding of WHO, the World Health Assembly hasadopted many resolutions requesting the Organization to develop internationalstandards, recommendations and instruments to assure the Quality of medicines,whether produced and traded nationally or response to these resolutions, the WHO Expert Committee on Specifications for pharmaceutical Preparations, which was originally created toprepare The International Pharmacopoeia, has made numerous recommenda-tions relevant to Quality assurance and control. Most of these recommendations,QAPIN 12/16/06 12:17 PM Page 1even though they were made several years ago, are still valid. Thus far, however,most have been available only as separate sets of recommendations containedin annexes to various WHO Technical Reports.

9 The recommendations are essen-tial to all concerned with the Quality assurance of medicines, but separate publications over a period of years has made it difficult to recognize them ascomplementary parts of a comprehensive system of Quality provide easy access to this information, the appropriate annexes andupdates are reproduced in the volumes of this publication. They are supple-mented with other material relevant to the Quality assurance of pharmaceuti-cals, some already issued in the form of WHO documents. The information ispresented in logical sequence as a series of administrative instruments and tech-nical elements of an overall Quality assurance system.

10 Readers should bear inmind that, in certain previously published texts, reference is made to WHOguidelines and other documents that have since been updated. Some of theseupdated texts are themselves included in the 1 of Quality assurance of pharmaceuticals : a compendium of guide-lines and related materialswas published by WHO in 1997. Material relating tonational drug regulations, product assessment and registration, The InternationalPharmacopoeiaand related activities, Quality control laboratories, internationaltrade in pharmaceuticals and their distribution, counterfeit products, basic testsfor pharmaceutical products and training of technical personnel is collected andreproduced in Volume 1.
