Nexium (Esomeprazole Magnesium) - Summary



Nexium (esomeprazole) is the S-isomer of omeprazole, which is a mixture of the S- and R- isomers. It is a proton pump inhibitor.

Healing of Erosive Esophagitis

NEXIUM is indicated for the short-term treatment (4 to 8 weeks) in the healing and symptomatic resolution of diagnostically confirmed erosive esophagitis. For those patients who have not healed after 4 to 8 weeks of treatment, an additional 4 to 8 week course of NEXIUM may be considered.

In infants 1 month to less than 1 year, NEXIUM is indicated for short-term treatment (up to 6 weeks) of erosive esophagitis due to acid-mediated GERD.

Maintenance of Healing of Erosive Esophagitis

NEXIUM is indicated to maintain symptom resolution and healing of erosive esophagitis. Controlled studies do not extend beyond 6 months.

Symptomatic Gastroesophageal Reflux Disease

NEXIUM is indicated for short-term treatment (4 to 8 weeks) of heartburn and other symptoms associated with GERD in adults and children 1 year or older.


H. pylori infection and duodenal ulcer disease (active or history of within the past 5 years) to eradicate H. pylori. Eradication of H. pylori has been shown to reduce the risk of duodenal ulcer recurrence [ see Dosage and Administration (2) and Clinical Studies (14) ].

In patients who fail therapy, susceptibility testing should be done. If resistance to clarithromycin is demonstrated or susceptibility testing is not possible, alternative antimicrobial therapy should be instituted [ see Clinical Pharmacology (12.4) and the prescribing information for clarithromycin ].


NEXIUM is indicated for the long-term treatment of pathological hypersecretory conditions, including Zollinger-Ellison Syndrome.

Published Studies Related to Nexium (Esomeprazole)

Randomised clinical trial: daily pantoprazole magnesium 40 mg vs. esomeprazole 40 mg for gastro-oesophageal reflux disease, assessed by endoscopy and symptoms. [2014]
AIM: To compare the efficacy of pantoprazole-Mg and esomeprazole in GERD... CONCLUSIONS: Pantoprazole-Mg 40 mg was at least as effective as esomeprazole

[Efficacy and safety of esomeprazole, compared with omeprazole, in maintenance therapy for reflux esophagitis -a phase III, multicenter, randomized, double-blind trial-]. [Article in Japanese] [2013]
A multicenter, randomized, double-blind study comparing the efficacy and safety of esomeprazole 20mg/day (E20) and 10mg/day (E10) with omeprazole 10mg/day (O10) for maintenance of remission in patients with healed reflux esophagitis (RE). For RE, at week 24, the estimated Kaplan-Meier recurrence-free rates were 92.0%, 87.5%, and 82.7% in the E20, E10, and O10 groups, respectively...

A combination of esomeprazole and aspirin reduces tissue concentrations of prostaglandin E(2) in patients with Barrett's esophagus. [2012]
CONCLUSIONS: In combination with esomeprazole, short-term administration of

Prospective, randomized, placebo-controlled evaluation of esomeprazole in coronary artery disease patients. EPAC: esomeprazole prevention of atypical chest pains. [2011.06]
BACKGROUND: Coronary artery disease (CAD) patients experience chest pain (CP) from cardiac and non-cardiac etiologies. OBJECTIVE: Proton pump inhibitor (PPI) treatment of CAD patients with atypical CP would result in less CP, as well as fewer emergency room (ER) visits for CP, medical evaluations, and hospitalizations... CONCLUSIONS: Concomitant esomeprazole therapy in CAD patients without active ischemia but with a history of atypical CP reduces number of patients with further CP symptoms and medical office visits for CP. Larger studies are needed to further evaluate PPI treatment on ER CP visits and hospitalizations in this patient population.

Fixed-dose combination of enteric-coated naproxen and immediate-release esomeprazole has comparable efficacy to celecoxib for knee osteoarthritis: two randomized trials. [2011.06]
CONCLUSIONS: Naproxen/esomeprazole magnesium has comparable efficacy to celecoxib for the management of pain associated with osteoarthritis of the knee over 12 weeks.

Clinical Trials Related to Nexium (Esomeprazole)

Nexium Study To Suppress Nausea During Chemotherapy [Terminated]
This study will look at a drug called esomeprazole, the newest PPI, as a way to further reduce the amount of nausea and vomiting seen in breast cancer patients receiving adriamycin or epirubicin chemotherapy. Esomeprazole may help protect the gut lining from the stomach acid and thus lessen the nausea and vomiting. If patients have less stomach sickness, they may be able to enjoy their daily routines much more while they are getting chemotherapy.

Viokase 16, Viokase16 Plus Nexium and Nexium Alone [Terminated]
Our primary hypothesis is that the addition of Nexium to Viokase 16 will decrease the chronic abdominal pain in patients with small duct chronic pancreatitis in a superior fashion compared to Viokase 16 plus placebo or to Nexium alone. A secondary hypothesis would be an increase in quality of life. Our objective is to elucidate the role of Nexium in the control of pancreatic pain, quality of life, and narcotic usage alone or when added to Viokase 16. Our endpoints are the reduction of abdominal pain, decreased pain medication usage, decreased ER visits and decreased hospital admissions for abdominal pain.

The Effect of Nexium and Probiotics on Insulin Secretion and Cardiovascular Risk Factors in Patients With Type 2 Diabetes [Completed]

Plasm Gastrin Concentrations in Response to Nexium Administration in Healthy Volunteers [Completed]
This dose response study is proposed to explore the extent to which Nexium increases endogenous gastrin concentrations and to assess whether Nexium treatment may be useful in the setting of islet cell transplantation for type 1 diabetes to expand islet cells in vivo after transplant.

Study Comparing the Effects of Esomeprazole Adminstered Orally and Intravenously on Basal and Pentrigastrin-stimulated Acid Output in Subjects With Symptoms of Gastroesophageal Reflux Disease (GERD) [Completed]
The purpose of this study is to examine the effects of Nexium at a dose of 40mg administered orally compared to intravenously on the maximum acid output in subjects with symptoms of Gastroesophageal reflux disease (GERD).

Comments:   I had been taking Prevacid for years with success and no adverse drug reactions. I had to switch because my insurance would not pay for the Prevacid any more because there was a Generic form of Prevacid. I tried the generic but it was not effective so I was given the prescription for Nexium. The Nexium was effective but I was highly allergic to it.
