The full form of Pepsi is not an acronym, but it is named after the digestive enzyme pepsin and kola nuts used in the recipe. Pepsi was originally created and developed in 1893 by Caleb Bradham and introduced as "Brads Drink". It was renamed as Pepsi-Cola in 1898, "Pepsi" because it was advertised to relieve dyspepsia (indigestion) and "Cola" referring to the cola flavor. Some have also suggested that "Pepsi" may have been a reference to the drink aiding digestion like the digestive enzyme pepsin, but pepsin itself was never used as an ingredient to Pepsi-Cola.
