17 August 2021, Munich – In 2018, there was a shortage of life-saving blood pressure drugs for several months following a voluntary recall announcement by the FDA for medical products containing valsartan. The Active Pharmaceutical Ingredient (API) was contaminated with N-nitrosodimethylamine (NDMA), which could cause cancer and was detected during laboratory tests.1 As a result, many major pharmaceutical companies recalled batches of their medications containing valsartan from Chinese manufacturer Zhejiang Huahai Pharmaceuticals, the key manufacturer of sartans at the time. Now in August 2021, there are similar incidents like the Spanish Agency for Medicines and Health Products (AEMPS)2,3,4 reported the withdrawal of 120 different batches of medication containing valsartan and irbesartan also caused by NDMA impurities.5
Another incident occurred in May this year, when Teva and Bristol Laboratories voluntarily recalled drugs containing losartan potassium and irbesartan quoting similar NMDA impurities.6 The increasing number of recalls has already affected the raw material market for losartan potassium (figure 1).
Global prices for the substance were fluctuating between 109.5 USD/kg and 121.8 USD/kg in the second half of 2020. During the following 4 months prices further decreased by 24.5% reaching a two-year low of 92.1 USD/kg in April 2021 (the all-time low of 53 USD/kg was reached in June 2017). This was followed by a 12.4 % price increase from April to June 2021.
Global prices for both intermediates (KSM) of losartan potassium, 2-cyano-4-methylbiphenyl and 4-bromomethyl-2-cyanobiphenyl dropped by 44.9% and 48.5% respectively from July 2020 to June 2021. This price decrease was quite stable throughout the year with the exception of a temporary price spike of 36 USD/kg for 4-Bromomethyl-2-cyanobiphenyl in December 2020. (see figure 2)
Taking a closer look into the manufacturing landscape of losartan potassium, manufacturers are located in 5 countries with a large majority in India. But with most of the suppliers for 2-cyano-4-methylbiphenyl and 4-bromomethyl-2-cyanobiphenyl located in China, the entire supply chain for losartan potassium is highly dependent on China as main manufacturing country.
