Racetin M Tablets

Adult dose

Typically, 2 tablets are taken orally twice a day, in the morning and just before bedtime, regardless of meals. 1) Gastric and duodenal ulcers 2 tablets taken twice daily or 4 tablets taken once daily just before bedtime. Particularly for patients with duodenal ulcers, taking 4 tablets twice daily in the morning and before bedtime can achieve a higher treatment rate. For ulcers or ulcers from nonsteroidal anti-inflammatory drug use, the dosage is the same in combination therapy to prevent gastric and duodenal ulcers. Typically, diseases caused by nonsteroidal anti-inflammatory drug use heal within 4 weeks, although healing times may occasionally extend for some patients. For patients who have had excellent short-term results with recurrence of the ulcer, the maintenance therapy is to take 2 tablets once daily before bedtime. 2) Gastroesophageal reflux disease Take 2 tablets, twice a day for 8 weeks, or take 4 tablets once daily before bedtime. However, for severe gastroesophageal reflux disease patients, the dose may be increased to 4 tablets 4 times a day. 3) Zollinger-Ellison syndrome Initial dosage is to start treatment with 2 tablets three times a day and may be increased if necessary. In the case of severe illness, under the guidance of a physician, up to 6 g of ranitidine can be administered daily. 4) Peptic ulcers, acute stress ulcers, and upper gastrointestinal bleeding due to acute gastric mucosal lesions When oral administration is possible, switch from injection to oral administration of 2 tablets twice a day. 5) Pre-anesthesia administration (prevention of Mendelson’s syndrome) Administer 2 tablets 2 hours before the induction of anesthesia. In this case, it is also recommended to administer 2 tablets on the night before surgery.

This drug should not be used in patients undergoing dialysis or in patients who have had allergic reactions to this medicine or its ingredients. It should also not be administered to patients with a history of acute porphyria, as it can cause side effects. It is safest not to use this drug in patients with impaired renal function, those who have undergone upper gastrointestinal surgery, in pregnant women or women who may become pregnant, and in preterm infants or newborns. Patients who are on a diet that restricts potassium intake should also avoid this drug. Patients with impaired liver function, a history of drug allergies, the elderly, and those with a history of renal disorders should exercise caution when using this drug. Patients taking nonsteroidal anti-inflammatory drugs, especially the elderly or those with a history of peptic ulcers, should have their condition monitored regularly. This drug can mask symptoms of gastric cancer, so patients with gastric ulcers or those over middle age who have newly developed or changed dyspeptic symptoms should confirm the malignancy before use. Patients with gastric and duodenal ulcers associated with Helicobacter pylori need bacterial eradication treatment. Patients in severe intensive care units should be cautious as they may develop gastric stones, and patients with hypophosphatemia should be aware that the aluminum component of this drug may interfere with phosphate absorption. Patients who have difficulty swallowing are at risk for respiratory complications, so this should be used with caution. Serious allergic reactions, such as anaphylactic shock, may occur rarely during use, so if symptoms develop, use should be stopped immediately and healthcare professionals should be informed. If allergy symptoms such as skin rash, urticaria, angioedema, fever, bronchospasm occur, medication should be discontinued. Blood abnormalities may occur, so if systemic malaise, weakness, bleeding, fever and other such symptoms are present, blood tests should be done, and use should be stopped if abnormal results are found. Rarely, symptoms of liver dysfunction can occur, so if jaundice or hepatitis symptoms appear, use should be stopped immediately. Cardiovascular abnormalities such as arrhythmias and vasculitis have been reported rarely, so be cautious if unusual symptoms occur. Gastrointestinal symptoms may include nausea, vomiting, constipation, diarrhea, and abdominal pain; stool color may change, but this is related to the components of the medication and does not require treatment. Neurological side effects, such as dizziness, drowsiness, confusion, seizures, insomnia, headaches may occur rarely, so especially patients with impaired kidney function should be cautious. Breast-related symptoms or erectile dysfunction, decreased libido have been rarely reported, but the causal relationship is unclear. Musculoskeletal abnormalities such as arthralgia, myalgia, and rhabdomyolysis may occur, so use should be stopped if symptoms develop. Skin rashes or hair loss have been reported rarely, and the tongue may turn black, but it recovers naturally. This drug should not be used for extended periods and should be used at the minimal effective dose while closely observing the treatment progress. Elderly patients or those with chronic lung diseases, diabetes, and immune suppression should take caution as the risk for pneumonia may increase while taking this drug. If dizziness or drowsiness occurs, driving or operating dangerous machinery should be avoided. This drug may affect the absorption or metabolism of other medications, so dosage adjustments or discontinuation of other medications may be necessary. Particularly, if used in combination with anticoagulants, the risk of bleeding should be monitored. When combined with sucralfate, an interval of more than 2 hours is recommended to prevent drug absorption inhibition. It is safest not to use this drug in pregnant women, women who may become pregnant, and nursing mothers. Safety and efficacy in pediatrics have not been established, so use should be avoided if possible. This drug may cause false-positive results on urine protein tests, so caution is needed during testing. In case of overdose, measures such as vomiting or gastric lavage are taken, and blood dialysis may be performed if necessary.
