h2 blocker
Danh từ
Số nhiều: h2 blockers
This term is a technical medical designation used primarily in clinical settings and pharmaceutical contexts. It describes a specific class of drugs, such as famotidine or ranitidine, that target the histamine H2 receptors in the gastric parietal cells to inhibit acid secretion.
In a patient-facing context, a healthcare provider might use the more general term "acid reducer," but "H2 blocker" is the precise terminology used to distinguish these medications from proton pump inhibitors (PPIs), which work through a different biological mechanism.
