These should result in smoothening conflicts of interests which are so numerous in the field of drugs, The participation of clinicians to accept and impl~ment the Essential Drugs Concept and Polic,y is still far frc~ reality more needs to be done to inform and convert prescribers on the still widespread misconceptions related to Essential Drugs. Now, there is even more reason to limit the use of inessential drugs and for goverr~aents to reappraise their National Health and Drug Policies and reformulate their political will. With only ii years ahead it seems improbable that the availability of essential drugs in the year 2000 will be reality for all of us, unless the econcmic situation changes for the bettezment of developing countries. A delicate balance ought to be struck between satisfying economic needs for drug * develolxnent and real health needs. It is clear that adequate drug use in developing countries is hampered by poverty, while both in developed countries and the upper segment in developing countries an overuse is likely to continue. PL 02 picture, surveys showed that in more than I00 developing countries a large part of the population do not get access to drugs.

While it was anticipated in the 70-s that the proportion of drug cons~nption of developing countries would increase in relation to the industrialized countries, the WHO Report on the "World Drug Situation" (1988) reveals a proportional decline of pharmaceutical consumption in the third world fram 24 % in 1976 to 2 1 % in 1985, while its population have increased from a proportion of 73 to 75 % of the whole world. In developing countries drug expenditure is in the range of a few dollars per capita with a very skewed distribution, and here the problem is one of nonaffordance for sizable percentages of populations. In the wealthy countries the increased demand for drugs and escalating drug prices will result in higher drug expenditure which is nowadays illustrated by the Japanese situation with an annual per capita drug censtmlotion of over $ 200. Rich as well as poor countries however, will face their own problems as regards to drug use an ~he ~ a r 2000. Inplementing an Essential Drugs Policy however may mean two possibilities for affluent countries this would mean depriving one from a wider choice of drugs, hut for many developing countries the availability of essential drugs would mean an even larger budget for drug procur~nent. Since its first conception of the WHO mediated Essential 9 Drugs Policy,which is a c(mponent of a National Drug Policy, in 1977, it became evident that a limited n%~aber of drugs (the real number is not important, hut the principle is) is satisfactory to cope with 90% of real health needs. But apart from the last mentioned, even affluent countries have difficulties in coping with the global trend of increased drug consunption. Unfortunately this has not always been able to attain in many countries where sources of funds are restricted and priority has been given to othe~ pressing country problems. Darmansj ah Drugs are an essential part of health service and therefore they should be available and accessible sufficiently in terms of variety, quantity, as well as quality, where they are needed.

Director, Osaka Bioscience Institute, 6-2-4 Furuedai, Suita Osaka 565, JapanĮSS~I~TIAL DRUGS FOR ALL IN THE YEAR 2000 REALITY OR FICTION ? I. Finally I would like to propose the working hypothesis that prostaglandins PGD2 and E2 induce sleep and wakefulness, respectively, and that the balance of these two substances in t.heir respective center is, at least in part, responsible for the sleep-wake cycle. In this presentation, I wish to briefly review current knowledge about the sleep-regulating activity of prostaglandins and to discuss (i) Prostaglandins and their receptors in the brain (2) Sleep-inducing effect of PGD2 (3) Awaking effect of PGE2 (4) Other sleep-regulating substances and their relation to PGD2 and PGE2 (5) Tentative conclusions and hypothesis. During the last several decades, an intensive search for endogenous sleep-regulating substances has been carried out in a number of laboratories throughout the world. Hayaishi Although we spend almost one third of our lifetime sleeping in bed or somewhere else, the molecular m e c h a n i s m of sleep-wake regulation has thus far been very little understood.
