Brief Summary
The principal investigator hypothesizes that participants receiving NSAID drugs with dyspeptic symptoms have increased production of gastric levels of free radicals. The primary objective of the study is to determine if Esomeprazole Magnesium increases gastric total antioxidant capacity and decreases gastric free radical production in humans. Participants (age 18 years and older) with no history of upper GI bleeding who are receiving non-steroidal anti-inflammatory drugs and then develop dyspepsia will be recruited from our primary care clinic in Washington, DC. All eligible participants will undergo biopsies of antrum and corpus. The participants will be randomized to receive either Zantac OTC or Nexium for 15 days. On day 15, all participants will undergo repeat upper endoscopy to obtain biopsies of antrum and corpus. Tissue samples will then be extracted to determine total antioxidant capacity and lipid peroxide levels (as an indirect marker of free radical production).

Eligibility Criteria
You may qualify if:
- Participants who are capable of providing informed consent, ages 18 years old and older. Partipants who are taking non-steroidal anti-inflammatory drugs on a daily basis must present with at least a 1 week history of dyspeptic symptoms including epigastric or upper abdominal discomfort or pain.
You may not qualify if:
- Participants presenting with only a complaint of heartburn will be excluded. Participants with alarm symptoms of vomiting, evidence of bleeding, inadvertent weight loss, or dysphagia will be excluded. Participants will be excluded if they have had upper endoscopy within 6 months prior to randomization. At the initial visit, participants will have a Helicobacter pylori IgG serology drawn and all participants with a positive serology will be excluded. Participants with a previous history of myocardial infarction, cerebrovascular infarction, gastric or duodenal ulcer disease, or carcinoma will be excluded. The study will not enroll participants who have received a H, K-ATPase inhibitor within the past 2 weeks. At the initial upper endoscopy, all participants with esophageal ulcer, esophageal cancer, gastric ulcer, gastric cancer, and duodenal ulcer will be excluded.
