Pharmaceutical companies in Ukraine aspire to develop their innovative medicinal products and successfully introduce them to the global market. However, along with the prospects of increased usage of these pharmaceuticals, there arises a challenge of heightened waste production, making them a part of the over twenty million tons of PPCPs produced annually. Consequently, one of the tasks in producing new pharmaceuticals is the development of methodologies and approaches not only for quality control but also for their determination in the environment matrices. The aim. Develop and validate GC-FID chromatographic method for the simultaneous determination of Enisamium iodide and Tilorone dihydrochloride, evaluate their applicability, and compare their "greenness" with the previously developed HPLC method. Materials and methods. The determination of the Tilorone dihydrochloride and Enisamium iodide was carried out by gas chromatography with a flame ionization detector using the Rxi-5 ms (30 m long, 0.25 mm outer diameter and 0.25 μm liquid stationary phase thickness). Results. Chromatographic GC-FID methods have been developed for the simultaneous determination of Enisamium iodide and Tilorone dihydrochloride. Optimal sample preparation conditions were established, and a validation process was conducted. A comparison with the previously developed HPLC method was made regarding "greenness." Conclusions. The developed GC-FID methodology is accurate and more environmentally friendly compared to the previously established methods. It can be recommended to determine Enisamium iodide and Tilorone dihydrochloride in the environmental matrices. It is considered environmentally friendly based on the overall GREENness (AGREE) scale, scoring 0.73 (>0.70), which demonstrates the environmentally favourable nature of the proposed analytical approach.
