Gelusil

Gelusil is an over-the counter drug that treats heartburn, acid indigestion and gas distributed by WellSpring Pharmaceutical Corporation. Its main ingredients are aluminum hydroxide, magnesium hydroxide and simethicone.

First used in 1939 as a liquid, it was created by the William R. Warner & Co., Inc., predecessor to Warner-Lambert(now Pfizer). It was trademarked in 1940 as a medicinal preparation for the "Rational Control of Gastrointestinal Hyperacidity."

Today, the drug is sold in the U.S. as chewable pill. The liquid version, still sold by Pfizer Limited India, was found by investigative journalist Jack Anderson after rifling through F.B.I. Director J. Edgar Hoover's trash.
