The advent of salicylates in the treatment of ulcerative colitis started in 1938 with the discovery of Salazopyrin by Nanna Svartz. This drug offered for the first time a therapeutic chance to patients with ulcerative colitis. In this paper we describe the fascinating history of Salazopyrin and salicylates from the first serendipitous observations to the last randomized clinical trials. Attention was paid to the pharmacokinetics and the mechanism of action of 5-aminosalicylates and, in particular, to the issue of the mucosal concentrations of 5-aminosalicylates and its therapeutic efficacy. Moreover a look at the new oral mesalazine formulations that allow the homogenous distribution of 5-aminosalicylate through all the large bowel was taken. Lastly, the possible use of mesalazine in the prevention of colorectal cancer was reviewed.
