5- Aminosalicylic acid (5-ASA) is metabolised in colonic mucosa by N-acetyltransferase 1 (NAT1). Common genetic polymorphisms in this enzyme result in rapid or slow acetylation. 5-ASA treatment causes side effects in up to 10 % of patients with ulcerative colitis (UC). We therefore determined genetic variations of NAT1 in patients with UC and looked for a possible association with the clinical response to 5-ASA.
