Implications of Over-the-Counter Proton Pump Inhibitors for Patient Counseling by Pharmacists

Abstract

The article reviews the literature on the role of the pharmacist in patient counseling and discusses how that role may apply to patients with frequent heartburn who are seeking an over-the-counter (OTC) treatment. Searches of the National Library of Medicine PubMed database were conducted using the terms "heartburn," "nonprescription," "therapy," "pharmacist," and "counseling," supplemented by additional searches on counseling for prescription products, and by the author's knowledge of pharmacy practice and the scientific literature. Accurate recognition of the signs of heartburn are an important first step in counseling a patient on the appropriate OTC medication; immediate referral to a health care provider is mandatory if cardiac pain or certain gastrointestinal symptoms are present. When counseling a patient about treatments for heartburn, the pharmacist should practice effective listening in an environment that is conducive to communication by the patient. Proton pump inhibitors are effective for the treatment of heartburn; the histamine2 receptor antagonists and antacids should also be considered for appropriate patients. Adverse events have been noted with proton pump inhibitors; however, overall the benefits significantly outweigh the risks and problems are unlikely to arise during the 2-week duration of OTC treatment of heartburn. Pharmacists can provide valuable services to patients with frequent heartburn, particularly with regard to counseling about the condition and appropriate OTC therapy. The availability of numerous OTC products, including antacids, histamine2 receptor antagonists, and proton pump inhibitors, enables pharmacists to fulfill an important clinical role and improve patient satisfaction.
