Blocid®

Sodium Alginate BP & Potassium Bicarbonate BP

Prescribing Details



Description

Blocid® is the combination of Sodium Alginate and Potassium Bicarbonate. Sodium Alginate is a naturally occurring substance. It reacts with the acid in the stomach to form a gel. Potassium Bicarbonate also reacts with the acid in the stomach to form bubbles of carbon dioxide. These bubbles are trapped by the gel formed by Sodium Alginate and they allow the gel to float like a raft on top of the stomach contents. The raft prevents acid in the stomach from flowing back into the esophagus. This relieves the symptoms of reflux such as heartburn. The mode of action of Blocid® is physical and does not depend on absorption into the systemic circulation. The raft lasts for up to 4 hours on top of the stomach contents and is then broken down in the digestive system and excreted in the feces.
