Mesalachin enteric soluble tablets are one of the aminosalicylic acid preparations, mainly used in the treatment of ulcerative colitis and segmental ileitis (Crohn’s disease), where the drug acts on the inflamed mucosa and has a significant dissipative effect on the inflammation of the intestinal wall. It can also be used to treat chronic colitis, mostly for symptom relief in mild and moderate patients as well as maintenance therapy, which is relatively good for controlling inflammation. When chronic colitis patients are treated with Mesalachin Enteric Dissolve Tablets, it is important to note that they should be used with caution in cases of renal and hepatic insufficiency, as well as in pregnancy and lactation, and are prohibited in cases of allergy to salicylic acid. Patients should strictly follow the medical advice and instructions of the drug. In case of severe headache, nausea, rash and other adverse reactions, use should be suspended and a doctor should be consulted as soon as possible. The treatment of patients with chronic colitis is limited by the anti-inflammatory effect of mesalachin enteric-coated tablets alone and requires the combination of other functional drugs to achieve a better therapeutic effect. In addition, if the anti-inflammatory effect of mesalachin enteric coated tablets is not good, glucocorticoids and immunosuppressive drugs can also be used: 1. Anti-inflammatory: glucocorticoids, such as prednisolone, and immunosuppressive drugs, such as azathioprine, mercaptopurine, methotrexate, etc., are helpful in controlling inflammation; 2. Antispasmodic: if patients with chronic colitis develop gastrointestinal spasm, it can be improved by atropine, nifedipine, otibuterol Pivetonium bromide, etc. to improve; 3, antidiarrheal: such as montelukast, etc., can play a role in repairing intestinal mucosa and reducing intestinal peristalsis, thereby reducing the symptoms of diarrhea. If chronic colitis does not improve significantly after long-term medication, or if it meets the indications for surgery, you can also choose treatment such as caesarean section surgery and laparoscopic surgery.
