guaifenesin has been researched along with Helicobacter Infections in 52 studies
Guaifenesin: An expectorant that also has some muscle relaxing action. It is used in many cough preparations.
Helicobacter Infections: Infections with organisms of the genus HELICOBACTER, particularly, in humans, HELICOBACTER PYLORI. The clinical manifestations are focused in the stomach, usually the gastric mucosa and antrum, and the upper duodenum. This infection plays a major role in the pathogenesis of type B gastritis and peptic ulcer disease.
