🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by competitively blocking histamine at the H2 receptors located on the parietal cells of the stomach. Histamine normally stimulates these cells to produce acid, so blocking the receptor reduces both the amount and the concentration of acid secreted. It also lowers pepsin output and reduces the response to other acid-stimulating substances like gastrin and acetylcholine. This effect helps to relieve symptoms and allows ulcers and inflamed tissues to heal.
