In recent years, there has been much work done due to increasing recognition that children need better medicines. The United States of America1,2 and the European Union3 have adopted regulations to encourage research and development of medicines for children; the World Health Organization (WHO) has been promoting “Make medicines child size”; and researchers and academics are starting to respond to the many unanswered questions about medicines for children, through research and international collaboration.

Countries that are working to meet the United Nations Millennium Development Goals related to maternal and child survival, however, need additional support to ensure access to medicines that will help achieve the specified targets. Fragile medicine supply systems, out-of-pocket payments and poor quality products are a particular challenge. These countries need urgent action to improve the quality, availability, supply and price of a small set of vital medicines.

The burden of disease data published by WHO list the major causes of maternal and child mortality.4 Effective medicines exist for the major causes of mortality in children: pneumonia, neonatal infections, malaria, human immunodeficiency virus (HIV), diarrhoea and tuberculosis. However, data from country surveys show that less than 50% of 20 medicines5 needed to treat priority conditions are available in health facilities. If these data are generally applicable to medicines for children, it is hardly surprising that child mortality is a problem. The availability of medicines that are needed for treating the causes of maternal death is less well known but, in general, availability of medicines in resource-limited settings is problematic.6

What are the priority products in addition to contraceptives and vaccines that might make a difference? WHO, the United Nations Children’s Fund and the United Nations Population Fund have identified a list of the top 30 medicines based on burden of disease and evidence of benefit, as recommended in current WHO treatment guidelines. These diseases/conditions and medicines are listed in Table 1. These medicines need to be made available as appropriately packaged, affordable quality products, for use throughout the health system – especially in first-line facilities in the community.

Table 2 is the “wish list” of products that could make a difference, if they were available. For some medicines, what is needed is a commercialized product – perhaps a dispersible tablet – in a pack size that is designed to provide a full treatment course. The evidence for the optimal dosage regimen for some products and indications is new, and therefore regulatory approval may be required to allow supply. And for some products, what is needed is development of packaging that allows delivery of a month's supply on the back of a bicycle – so no more bulky bottles or liquids.

The bigger challenges are the formulations that do not yet exist. For tuberculosis, there is a need for a fixed-dose combination product that contains all of the medicines needed for first-line treatment, in sufficient doses, without an unreasonable pill load and in a palatable form. As well, there are products currently used in facilities, which may need to be repackaged to make them safe in community settings. Injections of a single dose of the antibiotic ceftriaxone may save a child with severe pneumonia or sepsis from dying – IF the injection can be given safely by a health worker. Preparations, such as single-use preloaded syringes would be an advance, if sufficiently stable and the price was affordable to procurement agencies and donors.

But one of the simplest developments is also the one that needs the most significant shift in expectations. Carers, patients and health workers currently expect medicines for children to be syrups. Yet liquid formulations – syrups, suspensions and mixtures – are more expensive than solid formulations, are less stable, harder to ship and transport and may need cold-chain facilities – all of which make them a problem for low-resource settings. Replacing syrups with flexible solid oral dosage forms, which could be given as liquids at the point of administration, would potentially be a huge advance in the provision of medicines for children – IF the end user will accept them. In the rollout of a dispersible antimalarial especially formulated for children there have been barriers to acceptance, simply because end users are not confident to use this dosage form in children.

So what would make a difference? The aim of publishing a priority list is to focus global attention on a package of interventions that can produce results, if implemented consistently. Manufacturers should ensure that the quality products are available for sale and international and national procurement organizations should prioritize these medicines for purchase. Health professionals should know how and when to use them. Community organizations should ensure that they ask for the medicines that work. And by strengthening health-care systems to deliver these medicines consistently, there should be progress – in availability, access and, ultimately, in survival.
