It is rare, however, for the patient to take a central role and exert leadership in the design and execution of pharmacovigilance. Patient organizations in the inherited bleeding disorders community are among the most established and empowered, particularly in the rare disorders. In this review, two of the largest bleeding disorders patient organizations, Hemophilia Federation of America (HFA) and National Hemophilia Foundation (NHF), offer insights into the priority actions required of all stakeholders to improve pharmacovigilance.

The pharmaceutical and biomedical companies that develop them must demonstrate that they are effective, and the safety risks are limited or manageable, for regulators to approve them for use and sale. After the product has been approved and people are using it in their daily lives, it is important to continue to collect information about any negative side effects or adverse events; this is called pharmacovigilance. Regulators, like the United States (US) Food and Drug Administration, the companies that sell and distribute the products, and healthcare professionals who prescribe them are all required to participate in collecting, reporting, analyzing, and communicating this information. The people with the most firsthand knowledge of the benefits and harms of the drug or device are the patients who use them.

Those partners have a crucial responsibility to provide clear, easy-to-understand information to patients about any new safety concerns that come to light.

The aim of this study was to describe the pharmacokinetics of valproic acid (VA), lamotrigine (LTG), and levetiracetam (LEV) in a pediatric population using nonlinear mixed-effect modeling, while machine learning (ML) algorithms were applied to identify any relationships among the plasma levels of the three medications and patients’ characteristics, as well as to develop a predictive model for epileptic seizures. Methods: The study included 71 pediatric patients of both genders, aged 2–18 years, on combined antiepileptic therapy. Population pharmacokinetic (PopPK) models were developed separately for VA, LTG, and LEV. Based on the estimated pharmacokinetic parameters and the patients’ characteristics, three ML approaches were applied (principal component analysis, factor analysis of mixed data, and random forest). PopPK models and ML models were developed, allowing for greater insight into the treatment of children on antiepileptic treatment. Results: Results from the PopPK model showed that the kinetics of LEV, LTG, and VA were best described by a one compartment model with first-order absorption and elimination kinetics. Reliance on random forest model is a compelling vision that shows high prediction ability for all cases. The main factor that can affect antiepileptic activity is antiepileptic drug levels, followed by body weight, while gender is irrelevant. According to our study, children’s age is positively associated with LTG levels, negatively with LEV and without the influence of VA.

There are many stakeholders in the field of medicines safety, and by drawing on our different competences, skills and roles in the PV world, UMC strives to always pursue our vision: working together to advance medicines safety. UMC's different business areas focus on various external stakeholders, one of which focuses on the WHO Programme of International Drug Monitoring (WHO PIDM). Since 1968, the programme has provided a forum for WHO Member States to collaborate in pharmacovigilance. This enables programme members to be alerted to patterns of harm emerging across the world, but which might not be evident from their local data alone. There are now over 170 member countries/territories. The programme's operational activities were moved to Uppsala in 1978 under the sponsorship of the Swedish government, which marked the starting point for our organization and its designation as one of WHO's 800 Collaborating centres - the WHO Collaborating Centre for International Drug Monitoring.1 UMC is custodian and manager of VigiBase, WHO's global database of reported potential side effects of medicinal products. This gold mine is used to generate insights for various PV stakeholders. The WHO PIDM members, which are usually the national regulatory authorities, collect reports of adverse events from patients, physicians, the pharmaceutical industry and other stakeholders within their national PV systems. VigiBase accumulates the data from programme members, and currently contains about 33 million case reports. For other external stakeholders, VigiBase data can be made available with limited level of detail via VigiBase Services, open to, for example, academia, the pharmaceutical industry and health care providers.2,3 Besides VigiBase maintenance, our Collaborating Centre also provides programme members with IT solutions for data collection and analysis in their national setting to support their mission for safe products in their markets. There are many IT solutions, but to highlight two: VigiFlow, for example, is a data collection and management system, used by over 100 members as their national safety database. And in VigiLyze, members have a powerful analysis tool free of charge, which can analyse national data as well as data in regional collaborations with instant access to the global data in VigiBase and others' experiences as a reference. Safety signals found by UMC and other programme members are also available in VigiLyze. The Collaborating Centre generates and shares credible and evidence-based information on the safety of medicines and vaccines for further decision-making by regulators and scientific high-level committees. That work relies on the use of sophisticated methods for signal detection, but also on internal and external clinical expertise. Selected signals are also published in scientific journals to reach a broader audience such as the prescribers.

Themes encompassed PV systems, definitions, individual case safety reporting, aggregate reporting, and risk management. Under PV systems, aspects of the quality management system were outlined, that is, the legal basis for PV, a description of the marketing authorisation holder's (MAH's) PV system, archiving of data, contracting of PV tasks, and the duties of the person responsible for the MAH's PV obligations. Definitions of the key terms and major stakeholders were identified. Reporting of individual case safety reports (ICSRs) was explicated by considering the criteria for reporting, categories of reportable information, expedited reporting requirements, reporting timelines, and ICSR reporting format. Aggregate report submission during the development and post-marketing phases was addressed. Risk management encompassed signal detection, re-evaluation of the benefit-risk ratio, the safety decision-making process, risk management planning, risk minimisation and safety communication.</p><p><strong>Conclusion: </strong>The developed checklist can contribute towards assisting SADC NMRAs to formulate national PV guidelines that reflect current international practice, with local context incorporated.</p><p><strong>Plain language summary: </strong><b>Developing a checklist for the evaluation of medicine safety guidelines in Southern Africa</b> <b>Introduction:</b> In Southern African Development Community (SADC) countries, the guidelines for medicine safety [pharmacovigilance (PV)] that marketing authorisation holders (MAHs) and healthcare professionals need to adhere to, are not aligned.
