Improving Delivery of Aminosalicylates in Ulcerative Colitis

Effect on Patient Outcomes
  • Nielsen Q. Fernandez-Becker

Review Article


Developments in drug delivery technology have expanded the formulations of 5-aminosalicylic acid (5-ASA) available to clinicians over the last 50 years. Delivery of adequate doses of 5-ASA to the colon can be achieved by pH-dependent, delayed-release or pro-drug formulations. Despite some variations in the pharmacokinetics between individual preparations, the clinical effects in induction of response and maintenance of remission in ulcerative colitis appear to be consistent. Direct comparison studies between different preparations haveyielded similar results in primary endpoints, although differences in secondary endpoints or post hoc analyses have been noted. The development of delivery methods that allow once-daily administration represents a potential means to improve the low medication adherence rates reported in patients with ulcerative colitis.
