USP, FDA update quality standards for common drugs

The U.S. Pharmacopeial Convention is working with the FDA and the Consumer Healthcare Products Association to update the quality standards for common medicines. It's part of a USP plan to assess drug data in the USP and National Formulary compendia, with an eye toward updating test procedures to keep pace with technology. On the common-medication list is acetaminophen, among the highest-volume OTC drugs and also used in prescription meds. The FDA has recommended a test for impurities and degradants in products containing the ingredient. USP release
