Fourier Transform Infrared Spectroscopy (FTIR) was employed to analyze the chemical composition of pharmaceutical drugs, their labels, and packaging materials. The study examined three drug samples (Allergin, Bioflex, and Cofex), along with their respective packaging containers and labels, to identify functional groups that contribute to their structural properties and pharmacological behavior. The FTIR spectra of Allergin revealed the presence of hydroxyl (-OH) at 3260 cm?¹, nitrile (-C=N) at 2113 cm?¹, amine (-NH) at 1640 cm?¹, and alkyl (-CH) groups, indicating a complex molecular structure. Bioflex showed characteristic amine (-NH) absorption at 3335 cm?¹ and a sharp nitrile (-C=N) peak at 2110 cm?¹, suggesting a simpler but bioactive composition. Cofex exhibited strong carboxyl (-COOH) stretching at 1760 cm?¹ and nitrile (-C=N) at 2124 cm?¹, indicating possible ester or acid anhydride components. The FTIR analysis of packaging materials identified polyethylene terephthalate (PET), polypropylene (PP), and other polymeric compounds, with strong C=O (1719 cm?¹), C-H (2959 cm?¹), and C-O (1167 cm?¹) stretching bands. These findings highlight the significance of FTIR in quality control, drug formulation validation, and packaging material assessment, ensuring pharmaceutical safety and effectiveness.
