Dexlansoprazole in the treatment of esophagitis and gastroesophageal reflux disease.
OBJECTIVE
To describe the pharmacology, pharmacokinetics, and efficacy of dexlansoprazole in the treatment of heartburn associated with nonerosive gastroesophageal reflux disease (GERD) and healing and maintenance of healing of all grades of erosive esophagitis (EE).


METHODS
Literature searches were conducted using MEDLINE Ovid (1950-December 2009, week 4) and EMBASE (1980-2009, week 53) using the term dexlansoprazole. References from articles obtained from the search were evaluated for other relevant citations.


METHODS
All articles published in English evaluating the pharmacology, pharmacokinetics, efficacy, and adverse effect profile of dexlansoprazole were selected for inclusion.


RESULTS
Dexlansoprazole is the newest addition to the proton pump inhibitor (PPI) class and is approved for the treatment of heartburn associated with nonerosive GERD, healing of all grades of EE, as well as maintenance of healing of EE. Dexlansoprazole has a unique dual delayed-release formulation, which releases drug at 2 points in time; the first peak occurs 1-2 hours after administration and the second occurs within 4-5 hours after administration. In Phase 3 trials conducted in adults, researchers found that dexlansoprazole increases rates of healing of EE, as well as the maintenance of healing, compared to lansoprazole. Relief of heartburn symptoms was comparable among the dexlansoprazole and lansoprazole treatment groups. Common adverse effects of dexlansoprazole are similar to those of the other PPIs, including diarrhea, abdominal pain, nausea, upper respiratory infection, vomiting, and flatulence.


CONCLUSIONS
Dexlansoprazole provides another treatment option for the management of EE and symptoms of heartburn. Considering that the cost of dexlansoprazole is not favorable, further studies evaluating potential advantages over other agents are necessary to define the role of dexlansoprazole in the treatment of these conditions.
