Green Chemistry Approaches in Drug Synthesis: Sustainable Solutions for the Pharmaceutical Industry

The drug industry significantly contributes to global healthcare, but its manufacturing process is typically characterized by high energy consumption and the use of toxic materials, which largely leads to environmental degradation and rapid resource loss. In this regard, green chemistry has emerged as a revolutionary concept aimed at reducing the environmental burden of drug production. By incorporating sustainability principles, green chemistry seeks to develop safer and more efficient processes that minimize or eliminate the production of hazardous byproducts and toxic pollutants. (1) This report offers an overview of the green chemistry methods and key principles employed in pharmaceutical production. Particular emphasis is placed on innovative approaches, such as solvent-free reactions, biocatalysis, microwave-assisted organic synthesis, and the use of renewable feedstocks. These methods not only improve the environmental impact of drug production but also increase reaction efficiency, product yield, and process safety. (2) The latest developments and case studies are presented to illustrate the practical application and value of green chemistry in real pharmaceutical practice. Ultimately, this contribution highlights the necessity to adopt green practices in drug development in alignment with global environmental goals, to ensure long-term public health benefits. This step will catalyze the shift toward more environmentally friendly practices. (3)
