Proton pump inhibitors (PPIs) are a group of drugs whose main action is a pronounced and long-lasting reduction of stomach acid production. They are among the most widely sold drugs in the world, and are generally considered safe. The following are examples of PPIs: Mechanism of Action PPIs work by irreversibly blocking the hydrogen/potassium pump…
Introduction to Glaucoma Glaucoma is a group of eye conditions that damage the optic nerve, which is vital for good vision. This damage is often caused by abnormally high pressure in your eye and can lead to blindness if not treated early. But what exactly causes this pressure build-up? And how can we prevent it?…
Introduction to Antibiotic Stewardship Antibiotic stewardship is a coordinated effort to improve the use of antibiotics by promoting the selection of the optimal antibiotic drug regimen, dose, duration of therapy, and route of administration. It aims to achieve the best clinical outcomes related to antibiotic use, minimize toxicity and other adverse events, reduce healthcare costs…
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…
Antacids are medications that counteract the acid in the stomach to relieve indigestion, heartburn, and other stomach-related discomforts. Their primary function is to neutralize stomach acid, providing symptomatic relief from acid-related disorders. Let’s delve deeper into the pharmacology of antacids. Mechanism of Action Antacids work by a simple mechanism: they neutralize gastric acid, raising the…
