Drug therapy: including aminosalicylic acid drugs, glucocorticoids, immunomodulators and so on. (1) Aminosalicylic acid: such as 5-aminosalicylic acid, with inhibition of inflammation, scavenging free radicals and inhibition of immunity. (2) Glucocorticoids: such as prednisone, with the effect of inhibiting inflammatory response. Mostly used when aminosalicylic acid is ineffective.
