Naviscon Oral Suspension is an over-the-counter antacid formulation produced by Navana Pharmaceuticals Ltd., commonly used to alleviate symptoms associated with gastric reflux and hyperacidity. Each 10 mL of the suspension contains 500 mg of Sodium Alginate, 267 mg of Sodium Bicarbonate, and 160 mg of Calcium Carbonate. This combination works through a dual mechanism: Sodium Bicarbonate and Calcium Carbonate neutralize excess stomach acid, while Sodium Alginate reacts with gastric acid to form a gel-like raft that floats on top of the stomach contents. This raft acts as a physical barrier, reducing acid reflux into the esophagus and providing relief from heartburn and indigestion. Naviscon is indicated for conditions such as heartburn, gastroesophageal reflux disease (GERD), dyspepsia, and flatulence associated with gastric reflux. It is also considered safe for use during pregnancy and breastfeeding when used as directed. The typical dosage for adults and children over 12 years is 10–20 mL after meals and at bedtime, up to four times daily. However, it is contraindicated in individuals with known hypersensitivity to any of its components. Common side effects may include constipation, flatulence, and bloating. Patients are advised to consult a healthcare provider if symptoms persist beyond 7 days or if they have concerns about interactions with other medications.
