The battle against adulterated medications has grown to be a high-priority problem involving many players due to the harm to human health. To chemically analyze counterfeit materials and determine their level of patient risk, analytical laboratories participate in new investigations. Several techniques can be used to obtain specific information about the organic and inorganic composition, the presence of active ingredients or impurities, or the crystalline arrangement of the compound in the formulation. With the development of safer, more effective medications over the past few decades, the pharmaceutical industry has gained a major lead. Because of their high price, modern pharmaceuticals are always more susceptible to falsification or imitation. The public’s health is at risk due to inadequate variants of the original product, which frequently lead to treatment failure. Pharmaceutical items, whether chemical or herbal, are increasingly being characterized using infrared spectroscopy to track changes and identify fraudulent modifications. This review presents some of the most relevant papers related to the use of infrared spectroscopy in the analysis of adulterated drugs (chemical and herbal) products, published between 2021 and 2026.
