Effect of pantoprazole in older patients with erosive esophagitis

Gastroesophageal reflux disease and the elderly

Gastroesophageal reflux disease is a common disorder in all patients but a particular problem in the elderly, for whom the disease often presents with advanced mucosal damage and other complications. Symptoms are also not as reliable an indication of disease severity in older patients. Likewise, therapy is more difficult because of potential side effects and drug interactions.

Lansoprazole for long-term maintenance therapy of erosive esophagitis: double-blind comparison with ranitidine

In a study evaluating the efficacy and safety of lansoprazole to prevent the relapse of erosive esophagitis (EE), 206 of 241 patients (85%) healed after open-label treatment with lansoprazole 30 mg once daily for 8 weeks and received double-blind maintenance treatment with lansoprazole 15 mg once daily or ranitidine 150 mg twice daily for up to 1 year. At 1 year, 67% of lansoprazole-treated and 13% of ranitidine-treated patients remained healed (P<0.001). Lansoprazole-treated patients experienced significantly greater symptom relief (P<0.001), and, if asymptomatic at entry into the maintenance phase, remained asymptomatic for significantly longer than ranitidine-treated patients (P<0.001). Symptom status correlated with healing (P=0.001), supporting the symptom-directed management of EE. Both treatments were well tolerated and no unexpected events occurred. Daily therapy with lansoprazole to prevent the relapse of EE is effective, well tolerated, and superior to ranitidine in the maintenance of healing and symptom relief.

Medical management of gastroesophageal reflux disease

Antisecretory therapies that raise intragastric pH provide the best healing of the esophageal mucosal damage that occurs in gastroesophageal reflux disease. Continuous maintenance therapy is also effective to reduce the likelihood of recurrence of esophagitis and control symptoms in the long term. Proton pump inhibitor (PPI) therapy is an effective approach for healing esophagitis and controlling symptoms. Endoscopic and surgical treatments may provide an option for patients who are refractory to PPIs in whom reflux has been clearly demonstrated. Long-term antireflux medication is often needed after surgical treatment because of persisting or recurrent pathologic reflux and symptoms. An alternative approach to controlling transient lower esophageal sphincter relaxations, such as the GABA-B agonists, deserves further study.

Pantoprazole: a proton pump inhibitor with oral and intravenous formulations

Proton pump inhibitors (PPI) are a significant part of therapy for most acid-related diseases including gastroesophageal reflux disease, peptic ulcer disease and acute gastrointestinal bleeding. Pantoprazole is one of several available proton pump inhibitor agents and provides dose-dependent control of gastric acid secretion. Pantoprazole has indications in gastroesophageal reflux disease and peptic ulcer disease, along with indications as co-therapy in the eradication of Helicobacter pylori infection and in the control of the acid secretion associated with the Zollinger-Ellison syndrome, as well as in NSAID ulcer prevention. Pantoprazole is available in both oral and intravenous formulations. It is effective across all age groups, although only indicated in adults (and adolescents in Europe). It has been approved for use in over 100 countries and has been used for over 13 years. Pantoprazole has an excellent safety profile and a low potential for drug-drug interactions. While still widely prescribed, pantoprazole and the other branded proton pump inhibitors are under considerable market pressure from the less expensive but similarly effective generic and over-the-counter formulations of omeprazole.
