India halts cough syrup production linked to Gambia deaths
The WHO said last week that laboratory analysis of four Maiden products – Promethazine Oral Solution, Kofexmalin Baby Cough Syrup, Makoff Baby Cough Syrup and Magrip N Cold Syrup – had “unacceptable” amounts of diethylene glycol and ethylene glycol, which can be toxic and lead to acute kidney injury.
It is one of the worst such incidents involving drugs from India, often dubbed a “pharmacy of the world”.
News website Moneycontrol earlier quoted the Haryana drugs controller as saying in a report that Maiden did not perform quality testing of propylene glycol, diethylene glycol and ethylene glycol, while certain batches of propylene glycol did not have the manufacturing and expiry dates.
Diethylene glycol and ethylene glycol are used in antifreeze and brake fluids and other industrial applications but also as a cheaper alternative in some pharmaceutical products to glycerine, a solvent or thickening agent in many cough syrups.
India’s health ministry said last week that samples of all four Maiden products that had been exported to Gambia had been sent for testing to a federal laboratory and the results would “guide the further course of action as well as bring clarity on the inputs received/to be received from WHO.”
The syrups had been approved for export only to Gambia, India says, although the WHO says they may have gone elsewhere through informal markets.
