Executive Summary
PHENOLPHTHALEIN LAXATIVES "MEDICAL VALUE" CONSIDERATION URGED by Warner-Lambert in a report submitted to FDA Aug. 26. Prepared by Felix de la Iglesia, MD, et al., Parke-Davis Pharmaceutical Research, the report recommends that "should regulatory agencies be willing to consider the extent of medical value of phenolphthalein and hence contribut[e] to a balance of the weight of evidence, some specific recommendations could be made to undertake studies over the next two to three years." FDA proposed banning the use of phenolphthalein in OTC laxatives Sept. 2 ("The Tan Sheet" Sept. 1, p. 1).
