One of the latest threats facing the global pharmaceutical industry and healthcare is the presence of spurious/substandard drugs in the market. The World Health Organization (WHO) estimates that counterfeit drugs account for approximately 5-8% of the total worldwide trade in pharmaceuticals. [1] According to the WHO, 'a counterfeit drug is one which is deliberately and fraudulently mislabeled with respect to identity, composition, and/or source.' This definition of counterfeit includes not only completely fake drugs but also those that have been tampered with, adulterated, diluted, repackaged, or relabeled so as to misrepresent the dosage, origin, or expiration date, as well as those substandard drugs that are cheaply produced in order to make unlawful profits. The Center for Medicine in the Public Interest (USA) estimates that sales in counterfeit pharmaceuticals will reach US $75 billion in 2010.

Reports show that substandard drugs are available in the market worldwide. These reports are not only from the poor or developing countries but also from the developed world. However, this problem is much more severe in developing countries than in countries such as the US, UK, Canada, and other industrialized countries. In 2000, the health ministry in Russia reported that 56 drugs were counterfeit. The following year, approximately 3.6% of all pharmaceuticals in Russia were found to be fake. [2] The United States Food and Drug Administration (US FDA) reported that in spite of stringent controls, the number of cases of counterfeit drugs had increased in 2001 compared to the number of cases five years earlier. [3]

There have always been doubts regarding the quality of the drugs available in the developing countries. [4] Reports of treatment failure and drug resistance are frequent, [5],[6],[7] and this is probably because of the use of substandard/counterfeit drugs in African and Asian countries. The other possible reasons could be the drugs' chemical instability, inappropriate storage and transport, and poor quality control during manufacturing. The quality of some pharmaceutical products that are exported to the least developed countries do not even meet basic quality standards. In a random quality testing in Nigeria, 48% of the samples of different categories of drug products were found to be outside the British Pharmacopoeia (BP) limits for drug assay. Out of these, some drug products were even lacking in the active ingredient. Almost 40% of these drug products were manufactured in India. [8] In the recent past, the WHO has withdrawn the AIDS drugs manufactured by an Indian pharmaceutical company from the list when they found that the Contract Research Organization (CRO) that carried out the clinical study was not properly regulated as per the WHO standards. [9]

A study carried out in Nigeria, found that only three out of the eight brands of sulfadoxine-pyrimethamine tablets passed all BP quality specifications and were physically and chemically equivalent. [10] There have been several reports of substandard artesunate in South East Asia. From 104 samples of artesunate taken from South East Asian countries, including Myanmar (Burma), Cambodia, Vietnam, Laos, and Thailand, 39 (38%) were counterfeit and 30 (29%) contained no artesunate at all. [11] A recent WHO report provides information regarding the origin of counterfeit drugs in South East Asian countries. According to this study, Cambodia, China, Lao People's Democratic Republic, and Thailand have the largest number of illegal pharmaceutical vendors, unapproved pharmaceuticals, and illegal pharmaceutical manufacturers. [12] Interestingly, China and India are the leaders in counterfeit drug production and most of the bulk active ingredients produced by China and India are used in the manufacture of counterfeit pharmaceuticals worldwide. [1]

In 1999, the WHO published extensive guidelines to combat counterfeit drugs. [13] Recently WHO has suggested a rapid alert system for the relevant authorities in Asian countries to combat the global threat posed by counterfeit pharmaceuticals. [14] In 2004, a workshop was organized by the International Conference of Drug Regulatory Authorities (ICDRA) in conjunction with the Spanish Medicines Agency, with its main focus on combating counterfeit pharmaceuticals. Approximately 100 participants from several national drug regulatory authorities, nongovernmental organizations, international organizations, industry associations, and media personnel participated and expressed their opinions on national and international perspectives. [15] The need of the hour is to ensure the quality of the products being manufactured for consumption within the country or for export to other countries. WHO is planning to launch a task force to fight counterfeit drugs, vaccines, and other medical products. This task force will focus on increasing the awareness regarding counterfeit drugs and motivating consumers to report suspected counterfeit products. The International Medical Products Anti-Counterfeiting Task Force is looking to stop the trade in fake drugs, which kills thousands of people every year. [16]

Official government agencies, international bodies, and academia in Asian and African countries have always been aware of the availability of counterfeit pharmaceuticals. However, the data on counterfeit pharmaceuticals in India is only made available through the official government source. India has approximately 20,000 small manufacturing units that produce and supply pharmaceuticals at low cost. A survey conducted in the states of Maharashtra and Uttar Pradesh by a government agency revealed some interesting facts: (1) according to about 70% of patients, pharmacists/chemists suggest substitute pharmaceuticals in case a prescribed pharmaceutical is not available; (2) around 78% of patients opined that chemists/pharmacists do not inform patients about such substitutions; (3) 43% of doctors accept that there are incidents of spurious/substandard drugs being sold in the market; (4) generic drugs from different manufacturers are available with differences of as much as 500% in prices; (5) inadequate quality checking by the respective drug authorities, poor drug awareness, and low literacy rates are the reasons being attributed for the flourishing market in spurious/ substandard drugs. [17]

One of the landmarks in the fight against counterfeit/substandard drugs in India was the Mashelkar Committee Report in 2003. This is a comprehensive report that made proposals to upgrade the Indian drug regulatory standards and guidelines to international standards and to tackle the problem of counterfeit/substandard drugs. On the basis of the cases analyzed by various state government regulatory authorities, 0.5% drugs have been reported to be spurious and, according to initial reports, approximately 10% are of substandard quality. According to a WHO report, India leads the Asian countries by producing 35% of Asia's counterfeit/substandard drugs. [18] Whatever be the actual figure, it is a fact that in India there is a large amount of such drugs present in the market. The main reasons which have been put forward for this are inadequacies in drug testing, severe shortage of regulatory inspectors, corruption, and lack of law enforcement.

The Mashelkar Committee has made two important recommendations: (1) strict vigilance must be maintained, with regular surprise checks at pharmacies and for the cause checks (suspicious checks) and (2) provision of quality testing facilities for pharmaceuticals. [17] Regular drug sample testing exercises also helps in identifying the incidence of counterfeits.

One of the major recommendations is with regard to the need for improving the drug testing facilities at the state and federal level. Adequate infrastructure is required to test pharmaceuticals. Only 15 Indian states have functional drug testing laboratories, out of which only seven are adequately equipped and staffed. At least 11 states have no drug testing facility. [19] Academic institutions (both pharmacy and medical colleges) with advanced well-equipped testing laboratories offer a ray of hope in India. There are 132 approved post-graduate education and research institutions in pharmacy. [20] These institutions can be established as quality-testing centers in collaboration with the regulatory agency. Likewise, bioequivalence testing facilities can be initiated in those institutions that have clinical facilities, e.g., the National Bioavailability Center (NBC) at the National Institute for Pharmaceutical Education and Research (NIPER), Chandigarh and the Ph.D Pharmaceutical Medicine program at Jamia Hamdard, New Delhi. The center at NIPER is accredited by WHO and is one of the two centers in the world recognized for conducting bioequivalence studies of fixed-dose combinations of antitubercular drugs, whereas the Pharmaceutical Medicine program at Jamia Hamdard is one of its specialized programs, where most research projects are based on bioavailability, bioequivalence, and drug interaction studies, etc. in healthy volunteers. In November 2006, the Chemical, Fertilizer, and Steel ministry announced the setting up of five more NIPER-like institutes in the metro cities of India.

All these efforts and the availability of sufficient infrastructure can ensure stringent regulation and improved vigilance over the quality of pharmaceuticals. Nigeria is an example of a country that is successfully fighting the problem of counterfeit drugs and looking to eradicate it altogether.
