Speaking with , Cantrell advised caution.“My study didn’t convey anything about safety, I just looked at potency of active ingredients,” he said.Though an active ingredient may be as strong as the manufacturer originally intended, this does not mean the overall drug — a chemical jamboree, essentially — remains non-toxic, he explained.
From manufacturer to FDA to pharmacist, the underlying principle is maximum safety.
The short, safe answer is a simple “no.” However the truth of the matter is much more intricate, a lot more interesting, and requires a bit of knowledge about the Food and Drug Administration (FDA).
In the late 1970s, the FDA first began requiring expiration dates on both prescription and over-the-counter medications.“To assure that a drug product meets applicable standards of identity, strength, quality, and purity at the time of use, it shall bear an expiration date determined by appropriate stability testing,” reads the agency’s regulation.
In the lab, tablets were dissolved, isotopes diluted, chromatography tests run.
Three times, the science crew tested and retested samples for listed active ingredients. Of the 14 drugs, 12 (or 86 percent) were present in concentrations at least 90 percent of the labeled amounts, which is the generally recognized minimum acceptable potency.
