The Ascend West and Central Africa programme, funded by the UK Foreign, Commonwealth and Development Office (FCDO) is supporting integrated preventative chemotherapy for up to five neglected tropical diseases (NTDs), including intestinal worms, lymphatic filariasis, river blindness, trachoma and schistosomiasis. The programme is implemented across 13 countries by a consortium of four leading international development partners: Sightsavers, Liverpool School of Tropical Medicine, Schistosomiasis Control Initiative Foundation and Mott Macdonald. This paper presents messages learnt from country assessments that took place prior to the global outbreak of coronavirus disease 2019 (COVID-19). These messages remain relevant post-COVID-19, with greater priority being given to the challenges for national NTD programmes in continuing to deliver mass drug administration (MDA) during the pandemic. Stakeholder coordination from the earliest stages of the pandemic has occurred at two levels: in the first mile with global partners of the NTD Supply Chain Forum and in the last mile with implementing partners in each country. This has been instrumental to manage delayed MDA, including the impact delays have on the shipment of NTD donated drugs and the distribution of stock held in country. The Ascend West and Central Africa programme is supporting countries with the resumption of MDA through a risk assessment and mitigation action (RAMA) process.

Despite pharmaceutical systems being fundamental to successful antimicrobial stewardship (AMS) programmes they are currently neglected and undervalued. Research and investment into pharmaceutical system optimisation and integration into AMS programmes presents an opportunity for countries, both high-income countries (HICs) and low- and middle-income countries (LMICs), to develop responsible, comparable and global AMS innovations and interventions.

Objectives The COVID-19 pandemic has highlighted both the vulnerabilities and the critical role of global pharmaceutical systems in enabling equitable access to medicines. In this personal view, we position the pharmaceutical system as a missed research and investment opportunity that, if integrated properly, would benefit antimicrobial stewardship (AMS) programmes within a One Health approach. Key findings The pharmaceutical supply management cycle (PSMC) illustrates the continuous interdependence between four key phases: selection, procurement, distribution and use. Furthermore, a PSMC is subject to external forces of market competition, policy and regulation – across human, animal and environmental health. We present examples of overlap in PSMCs across different One Health sectors and discuss the need for integration within human, animal and environmental health contexts. Summary Despite pharmaceutical systems being fundamental to successful AMS programmes, they are currently neglected and undervalued. Research and investment into pharmaceutical system optimisation and integration into AMS programmes present an opportunity for both high-income countries and low- and middle-income countries to develop responsible, comparable and international AMS innovations and interventions.
