Introduction to Antimicrobial Resistance Antimicrobial resistance (AMR) is a global health issue that has been steadily gaining attention. But what exactly is it? In simple terms, antimicrobial resistance occurs when microorganisms such as bacteria, viruses, fungi, and parasites change in ways that render the medications used to cure the infections they cause ineffective. When the…
Introduction H2 receptor antagonists, also known as H2 blockers, are a class of medications that are commonly used to reduce the production of stomach acid. They work by blocking histamine action on H2 receptors found in the gastric parietal cells, thereby inhibiting gastric acid secretion. Examples of H2 receptor antagonists include Cimetidine, Ranitidine, Famotidine, and…
