Answer

The five oral aminosalicylate preparations available for use in the United States are sulfasalazine (Azulfidine), mesalamine (Asacol, Asacol HD, Pentasa, Lialda, Apriso), balsalazide (Colazal), and olsalazine (Dipentum). Enema and suppository formulations are also available. All of these are derivatives of 5-aminosalicylic acid (5-ASA); the major differences are in the mechanism and site of delivery. Some of these agents also have unique adverse effects lacking in other agents of this class.
