(ess oh me' pray zol)
Nexium
Pregnancy Category C
Drug classes
Antisecretory agent
Proton pump inhibitor
Therapeutic actions
Gastric acid-pump inhibitor: Suppresses gastric acid secretion by specific inhibition of the hydrogen–potassium
ATPase enzyme system at the secretory surface of the gastric parietal cells; blocks the final step of acid
production; is broken down less in the first pass through the liver than the parent compound omeprazole,
allowing for increased serum levels.
Indications

Erosive esophagitis—short-term (4–8 wk) treatment for healing and symptom relief. Also used for
maintenance therapy following healing of erosive esophagitis

Reduction in occurrence of gastric ulcers associated with continuous NSAID use in patients at risk (> 60
yr, history of gastric ulcers) for developing gastric ulcers

WARNING: Arrange for further evaluation of patient after 4 wk of therapy for gastroesophageal reflux
disorders. Symptomatic improvement does not rule out gastric cancer.
If administering antacids, they may be administered concomitantly with esomeprazole.
Ensure that the patient swallows capsule whole; do not crush, or chew; patients having difficulty
swallowing may open capsule and sprinkle in applesauce or disperse in tap water, orange or apple juice,
or yogurt; do not crush or chew pellets.
Obtain baseline liver function tests and monitor periodically during therapy.
Maintain supportive treatment as appropriate for underlying problem.
Provide additional comfort measures to alleviate discomfort from GI effects and headache.
Establish safety precautions if dizziness or other CNS effects occur (use side rails, accompany patient).
