About Fanit 40mg Tablet

Fanit 40mg Tablet is used to reduce acid production in the stomach. It treats stomach ulcers (gastric and duodenal ulcers), reflux oesophagitis, and Zollinger-Ellison syndrome. Stomach ulcers are painful sores present on the inner lining of the stomach. Reflux esophagitis is the inflammation of the oesophagus (food pipe) that causes the backward flow of stomach contents into the oesophagus. Zollinger-Ellison syndrome is a condition in which the tumours formed in the pancreas (produces enzymes for digestion) and duodenum (part of the small intestine) increase stomach acids.

Fanit 40mg Tablet contains ‘Famotidine’, which acts as an antacid. It inhibits the H2-receptors present in stomach cells. It reduces the production of acid and the volume of gastric secretions. As excess acid can cause inflammation of the oesophagus, stomach, and intestine, a reduction in the production leads to improvement in the symptoms and condition.

Fanit 40mg Tablet must be taken in the dose and duration advised by the doctor. Sometimes, you may experience headaches, dizziness, constipation, and diarrhoea. Most of these side effects of Fanit 40mg Tablet do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.

Uses of Fanit 40mg Tablet

Histamine binds to the H2 receptors present in the parietal cells of the stomach and stimulates the production of acid. Fanit 40mg Tablet binds to these receptors and blocks the histamine action. It also decreases the gastric secretion content. It also reduces the gastric secretion stimulated by food, caffeine, insulin, and pentagastrin. Caffeine, insulin (used in the treatment of diabetes), and pentagastrin (a synthetic drug that aids in diagnosing thyroid malignancy) stimulate gastric acid secretion.
