Introduction

Normacid is an antacid and anti-ulcer medication used to treat ulcerative colitis, gastroesophageal reflux disease (GERD), and other acid-related disorders such as gastritis and peptic ulcers. It works by decreasing the amount of acid in the stomach, which helps to reduce pain and discomfort associated with these conditions.

Uses

It is also used to treat conditions of the esophagus, intestines, and stomach that involve too much acid secretion, such as Zollinger-Ellison syndrome.

Mechanism of Action

Normacid works by blocking the action of histamine in the stomach and small intestine. Histamine is a chemical released by cells that helps to stimulate acid production in the stomach. By blocking it, cimetidine reduces acid production and can help to relieve pain and discomfort caused by acid-related disorders.
