Epidemiology
More than 10,000 cases of potential calcium channel blocker toxicity occurred in the United States in 2010. When death occurs in medicine overdose, heart medications are the cause more than 10% of time. The three most common types of heart medications that result in this outcome are calcium channel blockers along with beta blockers and digoxin. References

Reactive gastropathy, chemical gastropathy also called gastritis of « C type » or "chemical gastritis" is an abnormality in the stomach caused by chemicals, e.g. bile, alcohol, and characteristically has minimal inflammation. Cause
Reactive gastropathy has a large number of causes, including:

Alcohol use disorder. Bile reflux, such as may be seen post-Billroth II. NSAIDs. Diagnosis
The diagnosis is by examination of tissue, e.g. a stomach biopsy. Relation to gastritis
Reactive gastropathy is morphologically distinct entity  that can be separated from gastritis, which by definition has a significant inflammatory component. As a reactive gastropathy may mimic a (true) gastritis symptomatically and visually in an endoscopic examination, it may incorrectly be referred to as a gastritis. Even aware of the underlying etiology of the pathologic process, e.g. NSAID use, the label "chemical gastritis" is applied to a chemical gastropathy. See also
