Nexium is a specific inhibitor of a proton pump (PPIs) of the parietal cells of the mucous layer of stomach. It is a form of Prilosec (Omeprazole). It is accumulated and transformed into an active form in the secretory tubules where it inhibits secretion of hydrochloric acid. Nexium is used to treat gastroesophageal reflux disease (GERD), Zollinger-Ellison syndrome, promote healing of erosive esophagitis, eradication of Helicobacter pylori together with antibiotics, preventive therapy of ulcers after treatment with anti-inflammatory non-steroid medications.
Dosage and directions

Nexium increases blood levels of diazepam (Valium) by decreasing the elimination of diazepam in the liver. Nexium and other PPIs reduce the absorption and concentration in blood of ketoconazole (Nizoral) and increase the absorption and concentration in blood of digoxin (Lanoxin). Co-administration of Nexium with Clarithromycin increaes area under the plasma concentration time curve (AUC) of the first. Nexium may slow down metabolism of such medications: citalopram, diazepam, clomipramine, phenytoin, imipramine. Consequently their dose should be corrected.
