Abstract: Researchers procured a range of antimalarial, antibiotic and antimycobacterial drugs from cities in six countries: Ghana, India, Kenya, Nigeria, Tanzania, and Uganda. Semi-quantitative thin-layer chromato-graphy (TLC) and disintegration tests, Raman spectrometry, and near-infrared (NIR) spectrometry were used to measure the concentration of active ingredients and excipients (spectrometry only) to deter-mine whether the tested samples were of good quality. Overall, 15% of tested samples failed TLC, 13% of tested sam…
Keywords: Raman and near-infrared spectrometry; thin-layer chromatography; counterfeit and substandard drug production; regulation of drug quality.
