Description
Description
Ranitidine 300mg tablets primarily exert their action by inhibiting the H2 (histamine-2) receptors in the stomach. This mechanism is crucial in reducing gastric acid secretion. The active component, ranitidine, specifically targets and blocks these H2 receptors, which are responsible for stimulating acid production in the stomach’s parietal cells. By binding to these receptors, ranitidine effectively suppresses the activation of acid secretion, leading to a decrease in gastric acidity. This reduction in acid levels helps alleviate conditions related to excess stomach acid, such as peptic ulcers and gastroesophageal reflux disease (GERD).
