Esomeprazole is available in two strengths. Nonprescription (over-the-counter) esomeprazole is widely available as a treatment for frequent heartburn in adults. Heartburn is characterized by a burning pain in the chest that often occurs at night or after eating. Experiencing these symptoms twice a week or more is considered frequent heartburn.
Prescription-strength esomeprazole is used for the treatment of conditions caused by too much stomach acid in the body. This includes gastroesophageal reflux disease (GERD), duodenal and gastric ulcers, and erosive esophagitis, among others.
GERD, or gastroesophageal reflux disease, is a digestive disorder that primarily affects the lower esophageal sphincter (LES), the ring of muscle between the esophagus and stomach. This muscle opens when food enters your stomach and closes to keep it there. Stomach acid flowing the wrong way through this muscle causes a burning sensation in your chest (heartburn) accompanied by other symptoms such as difficulty swallowing, coughing and regurgitation of food or sour liquid. GERD can cause additional complications such as narrowing of the esophagus, ulcers in the lining of the esophagus, inflammation and infection (if contents from your stomach make their way into your lungs).
Duodenal and gastric ulcers are small sores that develop in the stomach or intestines. The most common cause of these sores is a bacterial infection. These forms of ulcers are not caused by stress, spicy foods, or stress. Duodenal and gastric ulcers can cause symptoms such as stomach pain, bloating, heartburn, and nausea.
Erosive esophagitis occurs when the tissue lining the esophagus is damaged. This is usually caused by acid reflux. Erosive esophagitis is a painful condition that can make it hard to swallow. When left untreated, this damage can cause a narrowing of the esophagus and frequent chest pain.
