Minimizing the risk of ethylene glycol and diethylene glycol poisoning in medications: A regulatory and pharmacopoeial response.

Pharmaceutical and personal care products, including syrups and toothpastes, extensively use glycerin, sorbitol, and propylene glycol. However, past incidents of ethylene glycol (EG) and diethylene glycol (DEG) contamination in these products have raised serious health concerns. Recently, several child deaths linked to contaminated cough syrup consumption have heightened concerns regarding the safety of Indian pharmaceuticals. In response, Indian drug regulatory authorities and the Indian Pharmacopoeia have implemented several measures to enhance the quality, safety, and efficacy of pharmaceuticals manufactured in India. These measures encompass risk-based inspections of manufacturing facilities, rigorous quality control checks of medicinal products intended for export, and increased transparency in the supply chain of excipients prone to EG and DEG contamination. Further, the Indian Pharmacopoeia has updated monographs for five high-risk excipients: glycerin, propylene glycol, sorbitol solution (70%, both crystallizing and non-crystallizing), and liquid maltitol. These efforts are consistent with global regulatory standards and aim to ensure the overall quality and safety of pharmaceuticals produced in India.
