Abstract:
The present invention relates to methods of testing medications to evaluate authenticity and identify counterfeits. The testing methods employ a reactive system comprising a solvent and an acid. Optionally, the reactive system can also comprise an organometallic agent. The testing methods can provide rapid results verifying the authenticity of an antimalarial medication. Further the test method can provide clear results that can be implemented and interpreted without special training, anywhere in the world. The test methods can offer quantitative and qualitative results. The test methods are based on reactions that yield different colors where the color can indicate the presence of an active ingredient, and the intensity of the color can indicate the concentration of the active ingredient.
