Management of intermittent claudication, the most common symptom of peripheral arterial disease (PAD), involves both risk factor modification and symptomatic treatment (WR Hiatt, N Engl J Med 2001; 344:1608; RM Schainfeld, J Am Board Fam Pract 2001; 14:443).

Aggrenox, a fixed-dose oral combination of aspirin and extended-release dipyridamole, is now being advertised for secondary prevention of a transient ischemic attack (TIA) or ischemic stroke.

The use of intracoronary stents in angioplasty procedures has improved both short- and long-term success rates. In recent years, drug-eluting stents (DESs) have largely replaced bare-metal stents (BMSs).

The FDA has approved the proton-pump inhibitor (PPI) dexlansoprazole (Kapidex - Takeda), a delayed release formulation of the R-enantiomer of lansoprazole (Prevacid - Takeda), for treating and maintaining healing of erosive esophagitis and for treatment of heartburn associated with non-erosive gastroesophageal reflux disease (GERD).

Cilostazol, a phosphodiesterase III inhibitor that has been used in Japan since 1988, has been approved by the FDA for treatment on intermittent claudication due to occlusive peripheral arterial disease.

Gastroesophageal reflux disease (GERD) is the most common GI condition encountered in the outpatient setting; it affects about 20% of people in the US.

About 50% of the world’s population is infected with Helicobacter pylori. These gastric bacteria can cause chronic inflammation and have been associated with development of gastritis, peptic ulcer disease, gastric adenocarcinoma, and gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Eradication of H. pylori can promote gastric healing, prevent recurrence of duodenal and gastric ulcers, and reduce the incidence of gastric cancer. Guidelines for treatment of H. pylori infection were updated recently.

The FDA has approved vonoprazan, a potassium-competitive acid blocker, copackaged with amoxicillin (Voquezna Dual Pak – Phathom) and with amoxicillin and clarithromycin (Voquezna Triple Pak) for treatment of Helicobacter pylori infection in adults. Vonoprazan is the first potassium-competitive acid blocker to be approved in the US. It has been available in Japan for treatment of various acid-related disorders since 2014. Vonoprazan is not available alone in the US.

The standard antithrombotic therapy for treatment of patients with acute coronary syndrome (ACS) is dual antiplatelet therapy with aspirin and clopidogrel (Plavix) or another thienopyridine, plus a parenteral anticoagulant while the patient is hospitalized, followed by antiplatelet therapy alone after discharge. The addition of the oral anticoagulant warfarin (Coumadin, and others) to dual antiplatelet therapy is generally not recommended for this indication because of fluctuations in its anticoagulant effect and the risk of bleeding. A recently published trial found that addition of...
