SPECIAL COMMUNICATION Access to Essential Drugs in Poor Countries A Lost Battle? Bernard Pe´coul, MD, MPH Pierre Chirac, PharmD Patrice Trouiller, PharmD Jacques Pinel, PharmD T HE EFFECTIVENESS OF DRUGS DE- pends on a long chain of fac- tors: research and develop- ment (R&D) of an appropriate pharmaceutical agent, production, qual- ity control, distribution, inventory con- trol, reliable information for health care professionals and the general public, di- agnosis, prescription, financial accessi- bility, drug dispensing, observance, and pharmacovigilance. At each level, those involved may have conflicting interests, and poor populations are the first to suf- fer the effects of frail links in this long chain. Today, entire populations lack ac- cess to essential quality drugs, and the situation appears to be deteriorating, fur- ther marginalizing much of the world’s population. Essential drugs are the foundation for nearly every public health program aimed at reducing morbidity and mortality in the developing world, and pharmaceu- tical expenditure can account for a high proportion of the total health expendi- ture of a country. Important health pro- grams that rely on essential drugs in- clude child survival programs, antenatal care, treatment of enteric and respira- tory pathogens, and control of tubercu- losis and malaria. Other major public health issues exist for which there is no effective pharmaceutical treatment. This article focuses on 4 main issues associated with the inaccessibility of drugs for populations in greatest need: (1) poor-quality and counterfeit drugs; (2) lack of availability of essential drugs due to fluctuating production or prohibi- tive cost; (3) need to develop field-based drug research to determine optimum utilization and remotivate R&D pro- grams for new drugs for the developing world; and (4) potential consequences of the recent World Trade Organization (WTO) agreements on the availability of old and new drugs. For all these issues, practical recommendations to improve the situation are proposed. The lack of access to essential drugs or vaccines because of economic rea- sons raises new human rights issues in a world that remains divided among wealthy countries, developing coun- tries, and the rest of the world. Yet, financial access to drugs does not nec- essarily mean correct use. Continuous training for health care professionals, dissemination of reliable pharmacologi- cal data, and improvement of the man- agement of drugs are fundamental steps in improving the quality of care in the developing world. THE PROBLEMS Examples of problems related to devel- opment and access to drugs and the mag- nitude of the public health problems con- cerned are given in TABLE 1. Counterfeit and Substandard Products Drug products must be produced ac- cording to good manufacturing prac- tices. 1 Unfortunately, many developing countries do not have the technical, fi- nancial, or human resources required for the application of such standards, and some developed countries may be less strict when the product being manufac- tured is destined for exportation. To- day, the quality of drugs and, therefore, their effectiveness and safety are less and Author Affiliations: Fondation Me´decins Sans Fron- tie`res, Paris, France.

Drugs offer a simple, cost-effective solution to many health problems, pro- vided they are available, affordable, and properly used. However, effective treatment is lacking in poor countries for many diseases, including African trypanosomiasis, Shigella dysentery, leishmaniasis, tuberculosis, and bac- terial meningitis. Treatment may be precluded because no effective drug ex- ists, it is too expensive, or it has been withdrawn from the market. More- over, research and development in tropical diseases have come to a near standstill. This article focuses on the problems of access to quality drugs for the treatment of diseases that predominantly affect the developing world: (1) poor-quality and counterfeit drugs; (2) lack of availability of essential drugs due to fluctuating production or prohibitive cost; (3) need to develop field-based drug research to determine optimum utilization and remotivate research and development for new drugs for the developing world; and (4) potential consequences of recent World Trade Organization agreements on the availability of old and new drugs. These problems are not independent and unrelated but are a result of the fundamental nature of the pharmaceu- tical market and the way it is regulated.

All rights reserved. less certain, especially for the poorest populations, who are attracted by lower- priced drugs sold outside pharmacies. Recent years have seen an increase in the prevalence of counterfeit and sub- standard drugs on the market. Counter- feit drugs are those that mimic authen- tic drugs; substandard drugs are those produced with little or no attention to good manufacturing practices. For example, during the meningitis epi- demic in Niger in 1995 (41 000 cases re- ported), Niger authorities organized an ex- tensive vaccination campaign. In March 1995, Niger received a donation of 88 000 Pasteur Me´rieux and SmithKline Beecham vaccines from neighboring Nigeria. A Me´decins Sans Frontie`res (MSF) team working with local health authorities no- ticed that the vaccines from Nigeria had an unusual appearance (eg, difficult re- constitution, black filaments in the solu- tion). Inquiries were made and Pasteur Me´rieux laboratories confirmed that the batch numbers and expiration dates did not correspond to their records. The drugs supplied had been substituted with coun- terfeit drugs. Tests carried out found no traces of active product, confirming they were false. Bottles and labels were cop- ied to perfection. 2,3 Pasteur Me´rieux sub- sequently filed a counterfeit suit. Some of the false vaccines (approximately 28 000) were located by batch number and de- stroyed. According to estimates, approxi- mately 60 000 persons were inoculated with false vaccines of a total 5 million vac- cinated during the campaign. Such a pro- duction would have necessitated an in- dustrial-scale manufacturing facility, and it is probable that the 88 000 vaccines identified as false did not account for the entire fraudulent production. Me´decins Sans Frontie`res teams have encountered similar field examples that lead to the following conclusions: orga- nized illegal circuits seem inclined to manufacture copies with the appearance of known trademark drugs (counterfeit) than comparatively less-expensive ge- neric products, whereas nonorganized il- legal circuits (small production) increas- ingly manufacture drugs that are substandard or inadequate, including ge- neric drugs. Poor quality may be accidental, with no intention to deceive, but oversights in manufacturing or neglected controls can have tragic consequences. Such was the case in recent decades with acetami- nophen syrups that contained, by mis- take, a lethal ingredient. 4,5 Fluctuating Production of Essential Drugs Drugs necessary for the treatment of cer- tain tropical diseases have begun to dis- appear from the market because they are commercially unprofitable. Many of these drugs were discovered in the 1950s and 1960s or earlier and are seldom or never used in wealthy countries. An example is seen in the effort to treat epidemic bacterial meningitis, caused by Neisseria meningitidis, which is rampant in sub-Saharan Africa. Efficacy of treat- ment with chloramphenicol in oily sus- pension (1 intramuscular injection re- peated after 48 hours) for bacterial meningitis is comparable with the tra- ditional treatment with ampicillin (in- travenous injections 4 times daily for 10 days). 6 The lower cost of chlorampheni- col in oily suspension—only one tenth the cost of ampicillin—and its simple ad- ministration make it particularly suit- able to the precarious conditions in de- veloping countries. 6 This is particularly important during epidemics. In Nigeria in 1996, for example, more than 100 000 cases of N meningitidis infections were re- ported. 7 However, production and avail- ability of chloramphenicol in oily sus- pension are no longer guaranteed. Roussel-Uclaf stopped its production in 1995 and transferred its technology to another laboratory, which began pro- duction last year. In the meantime, tem- porary solutions have ensured that a cer- tain (but far from sufficient) amount of chloramphenicol is made available. The circumstances described herein also apply to other serious illnesses, such as leishmaniasis and its treatment with meglumine antimoniate and African try- panosomiasis and melarsoprol (Table 1). The trypanocidal activity of eflorni- thine hydrochloride was discovered in 1985. 8 It is the only treatment proven ef- fective in cases in which African trypano- somiasis shows resistance to melarso- prol, and such resistance is becoming more frequent (20% in Omungo, Uganda). 9 This drug was sold at an ex- tremely high price and is now no longer manufactured. Only through a joint ef- fort of the World Health Organization (WHO), nongovernmental organiza- tions involved in fieldwork, coopera- tive bodies, and pharmaceutical compa- nies could this drug become available and affordable again. Prohibitive Costs The prohibitive cost of antiretroviral drugs for treatment of people with ac- quired immunoeficiency syndrome is well known. 10 There are many other ex- amples of drugs that are simply not af- fordable, most of which have been re- cently marketed and therefore are still patent-protected. Shigella dysenteriae type 1 dysentery is extremely contagious and, without ef- fective treatment, is lethal in 5% to 15% of cases. 11 Since 1979, this disease has been the cause of large epidemics in Af- rica (for example, in Malawi in 1992 and 1993 12 and in Burundi in 1994 11,13,14 ). Shigella dysenteriae type 1 bacteria quickly became resistant to traditional treat- ments. The only effective antibiotic drugs today are fluoroquinolones (eg, cipro- floxacin and norfloxacin). However, treat- ment with these new drugs is 10 times more expensive than the traditional treat- ment using nalidixic acid (approxi- mately $20 vs $2). 15 A special agreement was reached between Bayer Laboratories and MSF in 1997 to make available treat- ments with ciprofloxacin for 50 000 people for a unit price of $2 per treat- ment. This example shows that it is pos- sible to find a short-term ad hoc solution with the pharmaceutical industry, yet no midterm solution is anticipated. A recent study of bacterial meningitis causedby Streptococcus pneumoniaeinchil- dren aged 2 months to 3 years demon- strated that use of ceftriaxone sodium could reduce mortality from 66% to 32% compared with treatment with chloram- phenicol in oily suspension. 16 Both anti- biotics have a sustained action and require very simple protocols (daily intramuscu- ACCESS TO ESSENTIAL DRUGS IN POOR COUNTRIES ©1999 American Medical Association.

However, ceftriaxone treatment is 10 times more expensive than chloram- phenicol treatment. 16 Streptococcus pneu- moniae infection is also one of the main causes of severe acute respiratory tract infections—the primary cause of child mortality in Africa. 17 Therefore, ceftriax- one is vital but financially inaccessible to those populations that need it most. Prohibitive pricing also extends to pre- vention when new vaccines are not avail- able for the population most at risk. For example, hepatitis B virus and anti- Haemophilus vaccines are not accessible because of their steep price. Vaccines for hepatitis B, a disease predominantly found in eastern Asia and sub-Saharan Africa, 18 are approximately 10 times more expensive than other vaccines included in the Expanded Programme on Immu- nization promoted by UNICEF. 19 Essential Drugs Not Adapted to Field Conditions Tuberculosis caused the deaths of 3 mil- lion people in 1997, but the current treat- ment regimen, known as directly observed therapy—short course (DOTS), is imprac- tical and compliance is poor: only 23% of the world’s population has access to the WHO tuberculosis control strategy. 20 Research to simplify or shorten the DOTS regimen is needed to make the treatment more widely available. Furthermore, the emergence of strains resistant to com- monly used antibiotics has potentially dev- astating worldwide consequences. Cur- rent second-line treatments are too expensive, too complex, and too long, and therefore not realistic for field con- ditions. Priority should be given to sim- pler treatment guidelines that combine several antibiotics, which may not achieve the same level of efficacy of more com- plex protocols but are at least more prac- tical for the field. Today, those with mul- tidrug-resistant tuberculosis in countries with limited financial resources are not receiving treatment, which from a medi- cal and humanitarian perspective is com- pletely unacceptable. Access to drugs for poor populations would be greatly improved by research into new forms of existing drugs (eg, sus- tained action or rectal formulation) and the development of simpler treatment guidelines (eg, “one-shot” or short treat- ments). This type of research cannot be developed unless technical and finan- cial resources are made available and, more importantly, unless new efficacy criteria are applied to the treatment be- ing studied. Insufficient R&D for New Drugs Increasing drug resistance, adverse effects, and the lack of feasibility of cur- rent protocols point to the need for greater R&D into new drugs for dis- eases found in the developing world. From 1910 to 1970, the pharmaceuti- cal industry’s contribution was crucial to the fight against endemic tropical diseases: trypanocides and antiamebic agents in the 1930s (Bayer, Rhoˆne- Poulenc), chloroquine during World War II (Specia, Winthrop), and in the 1960s, the discovery of leading anthel- mintics (Janssen). Since then, pharma- ceutical companies have adopted a completely different strategy. 21 Among the 1223 new chemical enti- ties commercialized from 1975 to 1997, 379 (30.9%) are considered therapeu- tic innovations, but only 13 (1%) are spe- cifically for tropical diseases (TABLE 2). Two of these 13 drugs are actually up- dated versions of previous products (new formulations of pentamidine and am- photericin B), 2 are the result of mili- tary research (halofantrine hydrochlo- ride and mefloquine), 5 come from veterinary research (albendazole, benz- nidazole, ivermectin, oxamniquine, and praziquantel), and only 4 (0.3%) may be considered direct results of R&D activi- ties of the pharmaceutical industry (ar- temether, atovaquone, eflornithine, and nifurtimox). 22 Thus, it appears that pharmaceutical R&D is abandoning tropical diseases. There are 4 main reasons for this shift: 1. Costs and Risks of R&D Rela- tive to the Low Purchasing Power of Developing Countries. A typical R&D program (from initial results to registra- tion) would cost approximately $160 million and take between 8 and 12 years to complete. 23 Moreover, a successful out- come is not guaranteed (as was the case with oltipraz, an antibilharzial agent abandoned during clinical trials). 2. A Shift to More Profitable Pro- duction. To cope with large investments and reduce duplicate spending, pharma- ceutical companies started an unprec- edented cycle of industrial consolidation and mergers at the end of the 1980s (eg, Glaxo and Wellcome, Sandoz and Ciba- Geigy, Roche and Synthex). This consoli- dation focused on the most profitable seg- ments of the market (infectious diseases, cardiovascular conditions, cancer, derma- tology, and neurology), leaving tropical medicine largely out of the equation. 3. Competition and Counterfeit- ing of Drugs. Some drugs patented in the developed world are being copied in developing countries, where patent rights of pharmaceutical products are not pro- tected. Such production competes, some- times fiercely, with the innovating labo- ratory. For example, Bayer Laboratories, the patent holder of praziquantel, was outpriced by Shin Poong, a Korean labo- ratory that had developed a less- expensive manufacturing process. 24 In addition to copies of drugs resulting from a different notion of intellectual prop- erty rights, there are cases of pure and simple piracy (appropriation of the name and appearance of a trademark drug) that are frequent in countries where infor- mal markets play a significant role. 25 4. Cost of Adhering to Quality Stan- dards. There has been a general trend toward heavier regulations with which companies must comply to obtain ap- proval before marketing a drug prod- uct, which raise the costs of clinical de- velopment. The necessity of minimizing therapeutic risks leads to reinforcement of various quality standards (good clini- cal, laboratory, and manufacturing practices). 26 In practice, when clinical de- velopment incidentally identifies a prom- ising product (eg, eflornithine for Afri- can trypanosomiasis) or a new indication (eg, atovaquone for malaria, ivermectin for onchocerciasis, and albendazole for lymphatic filariasis) for the treatment of tropical diseases, the manufacturer of- ten decides not to market the drug, ACCESS TO ESSENTIAL DRUGS IN POOR COUNTRIES 364 JAMA, January 27, 1999—Vol 281, No. 4 ©1999 American Medical Association. All rights reserved. knowing it would be too expensive. The company generally decides to either make exceptional arrangements (eg, dona- tions in the cases of albendazole, atova- quone, and ivermectin) or takes nega- tive action (eg, discontinued production of eflornithine). GLOBALIZATION AND DRUGS: QUESTIONS AND CONCERNS A discussion of the current landscape in the area of drug availability would not be complete without a consideration of the increasing globalization of the phar- maceutical industry and the potential im- plications of recent and upcoming world trade agreements. Drugs: Another Industrial Product? The General Agreement on Tariffs and Trade (GATT) was signed on April 15, 1994, and was replaced by the WTO agreement, signed in 1997. 27 This agree- ment ratifies the worldwide imple- mentation of a free-trade economy. Its enforcement with regard to the pharma- ceutical sector raises certain concerns. Two types of provision seem particu- larly important for pharmaceutical com- panies in developing countries: that which puts an end to protectionist mea- sures and that which defines as manda- tory the protection of patents on drugs and their respective manufacturing pro- cesses, such as the Trade Related Aspects of Intellectual Property Rights Agree- ment (TRIPS). This is important because many developing countries do not fully acknowledge patent protection rights for pharmaceuticals. Newly Invigorated Research? Directors of pharmaceutical companies in the developed world have stated repeat- edly that the reason for not conducting research on tropical diseases is the lack of protection for innovations in some developing countries, which would also explain their limited investments in the countries concerned. 28 The moment the enforcement of patent protection becomes effective (in developing countries, no later than January 1, 2006) tropical disease research should logically start again, funded by Western companies or by manufacturers in developing countries. However, it is unlikely that Western manufacturers will devote much of their effort to nonsolvent populations, with or without patents. Manufacturing compa- nies in developing countries may actu- ally be motivated to invest more in research for new drugs, but such invest- ments will essentially respond to the need to shift their innovation capacity away from finding ways to copy the patented drugs of developed countries and to- ward discovering new drugs. 29 All things considered, tropical research may not have a more promising future, even if pat- ents are widely enforced.

JAMA, January 27, 1999—Vol 281, No. 4 365 Increasingly Prohibitive Prices? A study sponsored by US pharmaceuti- cal companies shows that granting drug patents does not tend to increase the price of drugs on the market. 30 This study, however, does not examine the prices of new innovative drugs and declares that, logically, the price of these new drugs should be higher. Naturally, when the manufacturing company is assured that its product cannot be copied, it holds a stronger position to negotiate prices with public health authorities. Moreover, the liberalization of international pharma- ceutical trade entails the development of parallel imports between countries where the same drug is sold at different prices. Pharmaceutical companies, which are consequently less inclined to grant sig- nificantly lower prices to less developed countries, may instead set unique world- wide prices or delay marketing their drugs in developing countries. 28 In either case, access to drugs is jeopardized. RECOMMENDATIONS WHO’s Revised Drug Strategy and the essential drugs concept are still key strat- egies to help improve access to essen- tial drugs and worldwide health. The es- sential drugs concept is evidence based, is simple, promotes equity, and is rooted in firm public health principles. WHO’s assistance to countries and advocacy work to promote the essential drugs con- cept and support countries in the for- mulation and implementation of na- tional drug policies has resulted in change for the better. This strategy is a proven success but it needs to be continued and strengthened, and new ways of imple- mentation have to be explored, given the changing context. In this spirit, the fol- lowing recommendations are made with respect to the 4 main issues that have been developed in this article. Procurement of Quality Drugs To improve the quality of existing drugs and their procurement, it is important to develop a permanent “Observatory of Drug Quality,” established by WHO in collaboration with organizations in- volved in the provision of essential drugs (eg, UNICEF, World Bank, the Euro- pean Union, and nongovernmental or- ganizations), that would oversee the implementation of adequate and effec- tive control procedures. The practical knowledge acquired by international or- ganizations to ensure the quality of ge- neric drugs must be shared with health authorities in developing countries. In- vitations to bid, required by big spon- sors such as the World Bank, European Union, and the US Agency for Interna- tional Development, must combine qual- ity criteria and lower costs. Further- more, procurement of drugs should be centralized at a national level to rein- force the responsibility of governments to make procurement, quality control, stock management, and distribution of essential drugs a priority. Increased Availability To provide better access to effective treat- ments for people in greatest need, sev- eral initiatives must be launched now, even if their results will not be realized immediately. In the short-term, practi- cal solutions involving the various part- ners must be found to maintain the pro- duction of essential drugs. By establishing public health priorities, new high- priced drugs must be made available to the poor through solutions similar to those implemented for Expanded Pro- gramme on Immunization vaccines, for which the supply is guaranteed by UNICEF. These drugs could be made available by creating centralized pur- chase funds whereby manufacturers would be guaranteed large sales vol- umes (financed by existing public and private funds). The funds would also set forth, by consensus, compliance with drug indications. Finally, operational re- search in the field must be promoted and developed in close collaboration with health care professionals in developing countries. Such research should pro- duce simple, efficient, and low-cost pro- tocols without losing sight of the risk- benefit factor for the poorest countries. Restart of R&D In an attempt to offset this costly struc- tural evolution in the pharmaceutical in- dustry, several public and private initia- tives have attempted to introduce public health criteria in R&D strategies. The 1975 Special Programme for Research and Training in Tropical Diseases (spon- sored by the United Nations Develop- ment Programme, World Bank, and WHO) has had outstanding results in strategic research (eg, entomology and pathogenesis) and has bolstered re- search potential (eg, epidemiology and training). However, strategies for prod- uct R&D that were actually launched in 1994 have yet to produce any convinc- ing results. 31 Nevertheless, this pro- gram has succeeded in raising aware- ness and has promoted reflection on potentially effective tools, even if most projects focus exclusively on malaria (eg, Multilateral Initiative on Malaria). The US Orphan Drug Act implemented in 1983 also has produced significant re- sults for rare diseases (157 new drugs were commercialized and 837 new in- dications were developed from 1983 to 1997), but no real impact has been seen with respect to tropical diseases. 32 We can therefore conclude that while such ini- tiatives may occasionally boost the de- velopment of new drugs (eg, deriva- tives of artemisinine and pyronaridin), they are unable to significantly redirect R&D toward tropical diseases. In the midterm, a legal and fiscal framework must be developed to spur R&D on tropi- cal diseases or related areas, similar to those developed in the United States for orphan drugs used in rare diseases. Humanizing the WTO Agreements On the whole, it is regretful that WTO agreements contain no specific provi- sions that would guarantee both fund- ing for ambitious tropical pharmaceuti- cal research and realistic pricing of potential drugs. However, some devel- oped countries were able to protect vul- nerable economic and business sectors (eg, textiles, agriculture, and culture). One can understand why wealthy coun- tries demand that developing countries comply with regulations on unfair com- petition. It is obvious that to meet press- ing public health needs, we need new es- sential drugs. To develop them, we need ACCESS TO ESSENTIAL DRUGS IN POOR COUNTRIES 366 JAMA, January 27, 1999—Vol 281, No. 4 ©1999 American Medical Association. All rights reserved. innovative research and industry. To fund new research, industry needs commer- cially viable results. It is therefore vi- tally important that the pharmaceutical industry collaborates with organiza- tions like WHO, UNICEF, and the World Bank to identify the challenges and get a clearer view of what they can achieve together in developing sustainable mar- kets for new tropical pharmaceuticals. It must be remembered that those de- veloping countries that are the main sources of cheap copies of patented drugs 31 are nevertheless relatively poor. Enforcing the WTO regulations will re- move a source of affordable copies of in- novative quality drugs on which the poor- est countries depend. Developing countries, particularly the less ad- vanced, should be encouraged to take ad- vantage of the limited alternatives of- fered by the WTO agreements. Specifically, they should be able to ob- tain compulsory licenses whereby na- tional authorities allow local manufactur- ers to circumvent patent rights (with certain conditions and in return for the payment of royalties to the inventor, as stipulated in article 31 of the WTO agree- ments). 33 Judiciously enforced, such an al- ternative seems to be the only recourse to balance the interests of the developing and developed world. WHO is in a unique position to argue the case for health at an international level. Health-related nongovernmental and consumer organizations certainly have a supportive role to play, but WHO is the only intergovernmental organiza- tion with a formal international man- date to protect and advance health in- ternationally. While WHO’s authority in this area has suffered in the last de- cades, part of WHO’s strategy should now be to clearly and unambiguously put health first and provide leadership in pro- moting access to essential drugs. CONCLUSIONS Access to essential drugs is a basic human right often denied to people in poor countries. However, it would serve no purpose to demand new pub- lic health or human rights in a manner that would suggest that such rights will soon become a reality. The current situ- ation points to the opposite. For a great proportion of the world, health condi- tions are worsening, and without fun- damental change in the pharmaceutical market, perspectives for improvement are not encouraging.
