Question: Is there any difference between sulfasalazine enteric-coated tablets produced by different manufacturers?

I have been here for more than two months, and the effect is very good. However, the trade name of a drug "sulfasalazine enteric-coated tablets" that has been taken all the time is Weiliufen. It's produced by Shanghai Sanwei Pharmaceutical Co., Ltd. Shanghai is out of stock recently. A drug, also called "sulfasalazine enteric-coated tablets", was found in other hospitals nearby. It was produced by Shanghai Dafu Pharmaceutical Co., Ltd., and the specification was also 0.25g g, and there was no trade name. There is no mention in the instructions that rheumatoid arthritis can be treated. I would like to ask Dr. Xue, can the sulfasalazine enteric-coated tablets produced by Shanghai Pharmaceutical Co., Ltd. replace the sulfasalazine produced by Shanghai Sanwei Pharmaceutical Co., Ltd. Is the dosage the same? Thank you. Dr. Xue Luan answered: 2010-02-1216: 47:15. The ingredients are the same. You can use it. There is no treatment for rheumatoid arthritis in the previous manual, but it has been used for rheumatoid arthritis for a long time. The doctor solemnly reminded: because I can't see the patient face to face, I can't fully understand the condition. The doctor's advice is for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor!
