Abstract

Background: Transdermal nicotine provides benefit in active ulcerative colitis but is often associated with adverse events (AEs). An oral formulation has been developed to minimize AEs. This study was undertaken to make initial observations on the safety and tolerance of oral nicotine therapy in inflammatory bowel disease; the effect on disease activity was also noted. Methods: Twenty-six patients with ulcerative colitis, 11 with active disease, and 5 patients with Crohn's colitis (2 with active disease) were given oral nicotine in 3-mg capsules, gradually increasing the dose to the maximum tolerated. AEs were recorded, concomitant prednisolone and/or azathioprine were reduced where possible, and disease activity was reassessed at the end of nicotine treatment. Results: Patients were followed for up to 12 months. Twenty-nine of 31 could tolerate at least 6 mg of nicotine each day, and 5 patients tolerated at least 18 mg daily. Twenty-four patients had nicotine-related nonserious AEs; over one half occurred during the period of dose escalation, but 7 discontinued treatment because of them. Six of the 13 patients with active disease became asymptomatic, whereas 3 patients in remission developed active symptoms; 11 patients reduced their concomitant medication. Conclusions: Oral nicotine is a safe potential treatment of inflammatory bowel disease, but there is considerable variation in tolerance.
