Sustainability is the ability to nurture or support a process for an extended period without compromising the needs of the future generation. Sustainable chemistry is a term that refers to the creation of chemical products and processes that decreases or remove the use and production of hazardous substances. Even though sustainable and green technologies have evolved in other scientific fields, their use in the pharmaceutical industry is still initial stage. Therefore, we need to work in green chemistry to ensure its growth in the pharmaceutical industry. Thus, the current review aimed to highlight the need for green chemistry or sustainable chemistry and its principles and its application in the pharmaceutical industry to practice environment-friendly production of pharmaceutical products and reduce or stop the production of harmful intermediates and products during the synthesis process.
