Green chemistry principles in the pharmaceutical industry: a way towards sustainable drug development

Green chemistry has increasingly become an essential paradigm in pharmaceutical research and production, meeting the growing demands of regulations and the environment. Green chemistry, which emphasizes concepts like waste reduction, atom economy, and the use of safer reaction conditions, makes it easier to create effective and sustainable methods for drug discovery and production. Green chemistry offers a variety of environmentally benign approaches for the synthesis of pharmaceutical compounds, aiming to minimize hazardous waste, energy consumption, and the use of toxic reagents during drug development. Such approaches include multicomponent reactions (MCRs), various catalytic strategies (homogeneous, heterogeneous, single-atom catalysis), and solvent-free processes. Green chemistry was applied in the pharmaceutical industry by enabling the manufacture of nanoparticles using environmental friendly techniques, the incorporation of green chemistry principles into pharmaceutical nanotechnology has completely transformed drug delivery systems. In addition to improving the therapeutic efficacy and biocompatibility of nanocarriers, this sustainable technique complies with legal requirements for ecologically conscious production. Similar to this, using biocatalysis in green chemistry frameworks reduces the need for harsh reaction conditions and hazardous chemicals by providing a benign, energy-efficient, and selective reaction environment for the synthesis of complex pharmaceutical intermediates and active ingredients. By promoting the use of renewable, biodegradable raw ingredients and green solvents, green chemistry simultaneously promotes innovation in cosmetic formulations while enhancing product safety and environmental effect. When taken as a whole, these developments highlight how important green chemistry is to change the pharmaceutical and cosmetics sectors toward high-performance, affordable, and sustainable solutions.
