Heartburn is a cardinal symptom
of gastro-esophageal reflux disease (GERD) and is among the most common patient
complaints.
Chronic GERD can cause heart burn, ulcers, scarring, and inflammation in the esophagus. It can also change cells that line the esophagus. This is known as Barrett's esophagus and it increases the risk of developing esophageal cancer.
Proton pump inhibitors are more effective for providing heartburn relief than H2 blockers. They also work better to help heal the esophagus.
To assess symptom control,
esomeprazole 20 mg on demand has been compared with placebo on demand
(maximum of one dose a day) for 6 months in a multi-center, double-blind study
in 342 endoscopy-negative patients with gastro-esophageal reflux disease.
There was complete resolution
of heartburn after 4 weeks of daily esomeprazole therapy. On-demand
therapy with esomeprazole was significantly more effective than placebo in
controlling symptoms.
Occasional heartburn usually is
not a cause for concern, but severe, ongoing acid reflux can be dangerous.
Severe heartburn that occurs at least twice per week may indicate GERD which
needs to be treated.
Esomeprazole is structurally
similar to other PPIs but is the first PPI to include only the active isomer,
which may lead to improved pharmacokinetic and pharmacodynamic characteristics.
Esomeprazole maintains
intragastric pH at a higher level and above 4 for a longer period than other
PPIs. Clinical studies have shown that esomeprazole is at least equivalent in
safety and efficacy to other drugs in the class. Esomeprazole has demonstrated
efficacy in the treatment of erosive esophagitis, the maintenance of healing of
erosive esophagitis, and the treatment of signs and symptoms of GERD.
