Improvement of gastric and duodenal ulcers (antacid effect), gastritis, and hyperacidity symptoms
This medication is used to treat gastric diseases such as gastric and duodenal ulcers and gastritis, and to improve symptoms like heartburn, nausea, vomiting, stomach pain, and belching due to hyperacidity. By neutralizing stomach acid, it stabilizes the gastric condition and alleviates discomfort. Thus, it effectively improves various symptoms associated with indigestion.
As Almagate, take 1 g orally three times a day, chewing after meals for 30 minutes to 1 hour. An additional dose may be taken before bedtime if needed.
