Executive Summary
IMMEDIATE-RELEASE PHENYLPROPANOLAMINE STATUS AT FDA QUESTIONED by Caprice-Greystoke in an Aug. 1 citizen petition that responds to a May 20 letter from FDA's OTC Monograph Staff Director William Gilbertson, PharmD, to the Nonprescription Drug Manufacturers Association. Gilbertson informed NDMA that FDA currently considers extended-release phenylpropanolamine to have Category I status for efficacy as an OTC weight-control product but that "existing data are inadequate to support immediate-release doses of 25-50 mg PPA" ("The Tan Sheet" May 30, p. 1).
