Difference Between Asacol and Delzicol
Delzicol® (mesalamine) is a medicine prescribed for the treatment of ulcerative colitis in adults. It comes in the form of a capsule (400 mg) and is a replacement for Asacol® 400 mg tablets, which are no longer available.
Although Delzicol and Asacol both contain the same active ingredient, there are many differences between the two drugs. Delzicol comes as a capsule, while Asacol came in tablet form. Also, there are different inactive ingredients in these two medications. Asacol contained an inactive ingredient called dibutyl phthalate (DBP), a substance which the FDA recommends removing from human drug products. Delzicol does not include DBP.
In addition, the prescribing information for Delzicol recommends that the drug be taken at least one hour before or two hours after a meal. No such recommendations were made for Asacol.
