Ravisud Tablet

Adult dose

Administer 1 tablet orally twice daily, usually regardless of meal timing, in the morning and before bedtime. 1) Stomach and duodenal ulcers: Administer 1 tablet twice daily or 2 tablets once daily before bedtime. For duodenal ulcer patients, administering 2 tablets twice daily in the morning and before bedtime may achieve a higher treatment rate. For ulcers caused by non-steroidal anti-inflammatory drug administration or long-term use of non-steroidal anti-inflammatory drugs to prevent the occurrence of gastric or duodenal ulcers, the dosage is the same. Usually, conditions caused by non-steroidal anti-inflammatory drug administration heal within 8 weeks; however, healing periods may be prolonged depending on the patient. For recurrent ulcer patients who showed excellent results with short-term therapy of this medication, maintain therapy with 1 tablet once nightly before bedtime. 2) Gastroesophageal reflux disease: Administer 1 tablet twice daily or 2 tablets once daily before bedtime for 8 weeks. However, for severe gastroesophageal reflux disease patients, the dose may be increased to 2 tablets 4 times daily. 3) Zollinger-Ellison syndrome: Start treatment with an initial dose of 1 tablet three times daily and may increase as necessary. In severe cases, a physician may prescribe up to 6 g of ranitidine daily. 4) Peptic ulcers, acute stress ulcers, and upper gastrointestinal bleeding due to acute mucosal lesions: Once oral administration is possible, switch from injection to oral administration, dosing 1 tablet twice daily. 5) Preoperative medication (to prevent Mendelson's syndrome): Administer 1 tablet 2 hours prior to anesthesia induction. Additionally, administering 1 tablet on the night before surgery is also beneficial.
