Due to inadequacy of data on the effectiveness of medicines regulatory systems in Zambia, this study was framed. The aim was to evaluate legislative provisions for medicines regulation under three legal-regulatory-frameworks in place over the period from 1995 to 2015. The study was structured in two distinct phases: the first involved document review of available legislation and secondary data relevant to the subject matter, covering the study period; the second involved a questionnaire survey for health practitioners to gather opinions on the effectiveness of the medicines regulatory systems in Zambia. Assessment of secondary data reported by Ministry of Health, and World Health Organisation on treatment outcomes and medicines regulation was conducted. Although it is not a very comprehensive review of the regulatory systems in one country, this book provides a basis for regulators, public health enthusiasts and social readers to reflect and generate ideas around medicines regulation.
