The samples were collected from various levels of the pharmaceutical supply chain across Zambia.

Data were extracted using a structured Excel database and analysed using Microsoft Excel, and GraphPad Prism Software was used for visualizations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Of the 198 samples, 86 (43.43%) were antiretrovirals, 54 (27.27%) antimalarials and 58 (29.29%) antituberculosis medicines.
