A new study has raised alarm bells in Washington and the pharmaceutical industry, revealing that the United States’ medicine supply is heavily dependent on China for key drug ingredients — a vulnerability that experts warn could threaten both public health and national security.
The analysis, released by the U.S. Pharmacopeia in its latest Medicine Supply Map report, found that the building blocks used to make many of America’s most vital drugs — known as key starting materials, or KSMs — are overwhelmingly sourced from just a few countries. Most troubling, 41% of these essential materials come solely from China, while another 16% are sourced exclusively from India.
