That Drug Expiration Date May Be More Myth Than Fact
In his lab, Gerona ran tests on the decades-old drugs, including some now defunct brands such as the diet pills Obocell (once pitched to doctors with a portly figurine called "Mr. Obocell") and Bamadex. Overall, the bottles contained 14 different compounds, including antihistamines, pain relievers and stimulants. All the drugs tested were in their original sealed containers.
The findings surprised both researchers: A dozen of the 14 compounds were still as potent as they were when they were manufactured, some at almost 100 percent of their labeled concentrations.
