Nizatidine was developed by Eli Lilly, and was first marketed in 1987. It is considered to be equipotent with ranitidine and differs by the substitution of a thiazole ring in place of the furan ring in ranitidine. In September 2000, Eli Lilly announced they would sell the sales and marketing rights for Axid to Reliant Pharmaceuticals. Subsequently, Reliant developed the oral solution of Axid, marketing this in 2004, after gaining approval from the U.S. Food and Drug Administration (FDA). However, a year later, they sold rights of the Axid Oral Solution (including the issued patent protecting the product) to Braintree Laboratories.
