Nexium Enters a Growing GERD Market
Article
Medical Marketing and Media, March 2001
Recently approved Nexium® enters a market that has increased more than 50 percent in the past five years.
Visits to office based physicians for treatment of GERD have increased for the past five years from approximately 7 million annually as of May, 1996, to 11.1 million in the year ending May, 2000, according to RxWatch from Scott-Levin.
Ninety four percent of those who sought treatment for GERD received a prescription during their visits.
Nexium will face competition from four proton pump inhibitors (PPIs) including the drug it is scheduled to replace, Prilosec®, which was introduced in 1989. In May 1995, TAP Pharmaceuticals launched Prevacid®, followed by Eisai/Janssen's Aciphex in September, 1999. Wyeth-Ayerst introduced Protonix in May, 2000.
During the first 6 months on the market, Protonix received 374,000 new prescriptions (NRxs); Aciphex®, 307,000 NRxs; and Prevacid, 301,000. As a better gauge of the market now, the 2 billion NRxs written in October 2000 were shared by Prilosec with 46 percent, Prevacid, 40 percent, Aciphex, 8 percent, and Protonix®, 6 percent.
