GREEN TOXICOLOGY AND SUSTAINABLE DRUG DEVELOPMENT: REDEFINING SAFETY IN PHARMACOLOGICAL RESEARCH

Abstract

Green toxicology represents an emerging interdisciplinary framework that integrates principles of environmental sustainability, green chemistry, and modern toxicological sciences to redesign drug development with reduced ecological and human health impact. Traditional pharmacological research and industrial drug manufacturing rely heavily on synthetic pathways that generate hazardous waste, employ toxic reagents, and often overlook long-term environmental persistence of pharmaceutical compounds. In contrast, green toxicology emphasizes safer-by-design principles, predictive toxicology, biodegradable drug systems, renewable raw materials, and environmentally benign synthesis strategies. The approach extends beyond conventional safety evaluation by incorporating life-cycle assessment, ecotoxicological modeling, in silico toxicity prediction, and systems-based hazard identification. Recent advances in computational toxicology, artificial intelligence, and omics technologies have significantly enhanced the predictive capacity of green toxicological frameworks, enabling early identification of hazardous molecular features and optimization of safer drug candidates. Furthermore, sustainable drug development integrates green manufacturing practices, solvent-free synthesis, biocatalysis, and nanomaterial-based eco-friendly drug delivery systems. Regulatory agencies and pharmaceutical industries are increasingly adopting sustainability metrics to minimize carbon footprint and chemical waste generation. Despite its promise, challenges remain in standardization, global regulatory harmonization, data availability, and balancing drug efficacy with environmental safety. This article explores the foundational principles, methodological advances, industrial applications, and future perspectives of green toxicology in pharmaceutical sciences. The integration of sustainability with toxicological assessment represents a paradigm shift toward safer, cleaner, and more responsible drug development practices that align with global environmental and public health goals..Green toxicology; Sustainable drug development; Green chemistry; Environmental toxicology; Predictive toxicology; Pharmaceutical sustainability; Ecotoxicology.
