5 Access to pharmaceuticals in a globalised world Flashcards
Overview Summary
Ensuring equitable access to quality pharmaceuticals remains a key global health challenge, with approximately one-third of the world’s population lacking access to essential medicines, a figure rising to over 50% in Asia and Africa (Leisinger et al, 2012). Access to safe, effective and affordable pharmaceuticals to prevent or treat illness is an essential part of effective healthcare provision (Seiter, 2010). The availability, accessibility, affordability, and appropriate use of medicines are not assured, and there is growing consensus that any effort to address the issue of access to quality pharmaceuticals must be multifactorial and take into consideration key health system building blocks such as adequate financing, a trained workforce, and regulatory capacity (Frost & Reich, 2008).
Overview Aim
The aim of this session is to provide you with an overview of the problem of inequitable access to medicines and its impact on health, with an emphasis on low- and middle-income countries (LMIC).
Overview Learning outcomes
By the end of this session, you should be able to: Explain the significance of pharmaceuticals on health systems in terms of financing, disease burden and rational use; Assess the global inequities in access to pharmaceuticals within and across countries; and Discuss the key challenges in ensuring a ready supply of affordable, quality pharmaceuticals in LMIC.

- Background
Access to healthcare, including pharmaceuticals, is a fundamental human right as clearly stated in the Universal Declarations of Human Rights in 1948. Essential medicines are a fundamental part of a health system and account for a large share of expenditure on health. Approximately US$1.42 trillion was spent on medicines in 2021, an increase from US$887 billion in 2010. This is forecast to increase to US$1.8 trillion by 2026 (Statista, 2022). Spending on pharmaceuticals is the largest item in household health expenditure in most LMIC (Yadav et al, 2012).
- Background
Although pharmaceuticals are key to adequate health care provision, a study in 2014 found that median availability of essential medicines was 62% globally, with substantial variation in availability across national income levels and WHO regions (Bazargani et al, 2014). Patients living in LMIC with a higher burden of infectious diseases are less likely to have access to adequate treatment for many reasons including lack of adequate funding, lack of infrastructure, and lack of trained staff. This results in preventable illness and death (Kruk et al, 2018). A study examining number of deaths in LMIC found that 5 million deaths in just the year 2016 could have been prevented if people had access to quality healthcare, including necessary drugs (Kruk et al, 2018). In 2021, the UNAIDS annual report stated that ‘under-investment in the HIV responses of low- and middle-income countries was a major reason why global targets for 2020 were missed’ (UNAIDS, 2021).
- Background
Pharmaceuticals were identified as a key component of a number of the Millennium Development Goals (MDGs) and most recently the Sustainable Development Goals (SDGs) (WHO, 2018b; UN, 2022). For example, MDG1 on eradication of extreme poverty and hunger is related to access to pharmaceuticals: access to medicines is linked to a healthier workforce, and a healthier workforce is one of the aspects contributing to economic development. MDG8 included a specific target for access to pharmaceuticals, aimed at providing access to affordable, essential drugs in LMIC in order to improve health. However, this target was deprioritised and dropped from the official report, which suggests that in reality meeting this goal was difficult (see Gotham et al, 2016 for a discussion of this). We will find out why this may have been the case as we go through the session.
- Background
Following the MDGs period, the SDGs were developed to address some of the failures of the MDGs. SDG3 targets improved wellbeing of all people, with a specific target on Universal Health Coverage, including access to essential health care services and to safe, effective, quality and affordable essential medicines and vaccines for all (UN, 2022).
- Background
Pharmaceutical policy is complicated as it transcends national boundaries and goes beyond the health sector (Seiter, 2010). It involves international and transnational policy regimes and agreements on trade, intellectual property, regulation, and industrial policy, and it involves bodies such as the World Trade Organization (WTO), the United Nations, and the World Health Organization (WHO). You will see throughout this session how these multilateral and intergovernmental arrangements are translated into national realities and how patients on the ground are affected by this multi-level policymaking.
Activity 1 Do some online research into the elements needed for access to pharmaceuticals to be guaranteed. The relevant WHO webpage is a good place to start: https://www.who.int/our-work/access-to-medicines-and-health-products; In addition to the products themselves, think about system elements required to deliver medicines to those who need them. Make a list of elements;
Summarise and post your findings on the discussion board for feedback from your colleagues and comment on at least one other post.
- The access to pharmaceuticals problem
We can approach the access to pharmaceuticals problem in a systematic manner using a framework adapted from one developed by Frost and Reich (2009). As you’ll see in the figure below, the key aspects of the framework are availability, affordability, accessibility, and acceptability, which we will discuss in more detail in the following sections.
2.1 The access to pharmaceuticals framework
It is important to mention that there are some overarching requirements for pharmaceuticals to be accessible, which are part of the ‘architecture’ of the framework. These include: adequate funding to ensure that medicines can reach the intended recipients; a workforce that is sufficient in number and appropriately distributed and trained, to provide advice and support to consumers; strong information systems and the ability to use this information to inform purchasing decisions and broader pharmaceutical policy; and an effective governance system capable of regulating the introduction of new products, ensuring the safety and appropriate distribution of existing products, appropriate enforcement and providing transparent procurement (Frost & Reich, 2008).
2.1 The access to pharmaceuticals framework
Many actors and organisations are involved in this framework, including pharmaceutical companies, manufacturers, Product Development Partnerships (PDPs), global health initiatives, governments, funding bodies, the World Health Organization, the World Bank, to name but a few. The roles and responsibilities of these actors will be discussed further in the sections below.
- Availability
All pharmaceutical products must go through the long, expensive process of research and development (R&D) and manufacturing. R&D is profitable because companies can charge monopoly prices under the intellectual property rights system. Central to this system is the concept of patents and the Agreement on Trade Related Aspects of Intellectual Property Rights (the TRIPS Agreement). We will discuss these later in this session.
3.1 Research & development
R&D is mostly conducted by and for high-income countries, which, in practice, has the effect that investment is made into diseases that primarily affect populations in high-income countries. This has been highlighted by the issues with production of vaccines for COVID-19, with many researchers suggesting that LMIC should be enabled to make their own vaccines rather than rely on supplies from high-income countries (Maxmen, 2021a). However, pharmaceutical companies are reluctant to do this, stating potential issues with quality and safety. A group of researchers in Africa has started trying to produce existing vaccines, although issues with this include access to technologies and the necessary raw materials (Roelf, 2021).
3.1 Research & development
Africa as a whole imports 70–90% of the drugs needed to treat their population (Chaudhuri and West, 2015), which is much higher than the corresponding data for China (5%) and India (20%), despite having comparable populations. Nkengasong and Tessema (2020) point out that Africa needs to develop effective local pharmaceutical manufacturing to avoid unnecessary deaths. For example, anti-retrovirals were first available in high-income countries in 1996, but these didn’t become available in some African countries until 2002. The ability to make these drugs locally would have saved many lives (Nkengasong & Tessema, 2020).
3.1 Research & development
Moreover, the availability of drugs to address neglected tropical diseases (NTDs), which disproportionately affect LMICs, is a significant problem (Eisenstein, 2021). In 2021, the WHO produced a roadmap assessing challenges in preventing and controlling these diseases (Casulli, 2021). This roadmap pointed to problems in NTD research associated with lack of funding, lack of R&D, and lack of interest and political will. Until these diseases begin to affect people in higher-income countries, sufficient funding is unlikely to be forthcoming.
3.1 Research & development
However, this situation may be changing as a result of several factors: 1. Philanthropic funding from foundations like the Bill & Melinda Gates Foundation (BMGF) and the Wellcome Trust aim to reduce the burden of NTDs through efforts to control, eliminate and eradicate these diseases (BMGF, 2022); 2. Renewed interest by pharmaceutical companies into these diseases, possibly as a result of ‘rewards’ given to companies who participate in this research, e.g., milestone payments or financial prizes and grants based on the impact of the product (Weng et al, 2018); and 3. The creation of new business models and new actors, e.g. PDPs: these are not-for-profit institutions that engage the public and private sectors to conduct R&D into neglected diseases (Hoogstraaten et al, 2020).
3.1 Research & development
A good example of PDPs is the Medicines for Malaria Venture (MMV), a not-for-profit organisation created in 1999 to discover, develop and deliver new antimalarial drugs (Medicines for Malaria Venture, 2022). MMV works with multiple partners around the world including multinational pharmaceutical companies, small pharmaceutical and biotechnology companies, universities, and research centres. Overall, this is an example of how PDPs have changed the R&D landscape.
3.1 Research & development
Once a medicine is developed and registered, it needs to be manufactured on an ongoing basis. There are some important facts to mention here. First, the lack of manufacturing capacity in low-income countries, which account for only 1% of global pharmaceutical expenditure. Second, some middle-income countries have increased their manufacturing capabilities in the past decades and are now increasingly supplying other LMIC. For example, Indian generic companies manufacture more than 80% of all the antiretrovirals bought by donors (Waning et al, 2010)
3.2 Distribution
Once pharmaceutical products are developed, registered and manufactured, the next issues are related to the distribution chain: selection, procurement, distribution and use (Frost & Reich, 2008). At the selection stage, officials at each country’s Ministry of Health need to review the health issues prevalent in their country and identify treatments of choice, considering what individual products and which dosage forms will be available at each level of the healthcare system. During this process, these officials compile a list of Essential Medicines that can satisfy the priority healthcare needs of the majority of the population, with cost of these drugs taken into account. WHO started this concept in 1977, with the Model List of Essential Medicines, which is updated every two years and is used as a template by public health officials (WHO, 2022a).
3.2 Distribution
Once essential medicines are selected, the second stage is the procurement of those medicines (Frost & Reich, 2008). Public procurement usually follows certain steps: first medicine requirements for the entire public health system are quantified; then a procurement method is chosen and normally there is a tendering process to guarantee competition under the logic that the higher the competition, the lower the prices. The respective government ensures quality is assured through the Medicines Regulatory Authority.
3.2 Distribution
The third stage is the process of transporting medicines from the place where they are manufactured or imported to the health facilities (Frost & Reich, 2008). This process is extremely important for certain products like vaccines which must be kept in certain conditions, such as carefully controlled temperatures to guarantee quality. The process involves numerous steps including clearing customs, transportation to warehouses where products will be stored, transportation to government stores where products can be kept closer to the health facilities and final delivery to drug depots and health facilities. This complicated process can be optimised by using computerised Logistic Management Information Systems to ensure efficient distribution. This distribution process can be managed entirely by the government or can be outsourced (see Bekele & Anbessa, 2021 for an interesting overview of this in practice). The final stage, use, relates to diagnosing, prescribing and dispensing medicines to patients.
3.2 Distribution
Challenges to this entire process include the lack of comprehensive procurement policies, fragmented procurement systems, lack of unbiased market information, and poor planning.
3.2 Distribution
Other problems like corruption and lack of transparency may affect all stages, especially when private companies are involved in the distribution process. There is the potential for supplies to be ‘held up’ at ports until a ‘tax’ is paid. For an interesting overview of this issue, see this 2016 report by Transparency International (https://www.transparency.org.uk/publications/corruption-in-the-pharmaceutical-sector). There are also problems specific to distribution like vertical and fragmented supply systems; insufficient funding for storage; distribution and inventory management systems; short shelf life; stock-outs when medicines are not available in health facilities; and problems with transportation like a poor cold chain. A cold chain is necessary when a product requires temperature-controlled storage and shipping, e.g., certain vaccines. If the cold chain is broken, the product may become ineffective (Frost & Reich, 2008).
