Patient-led variable dosing with balsalazide as long-term therapy for maintenance in ulcerative colitis: a 3-year...

The patient-centred approach is new to the management of ulcerative colitis. To date, it has only been shown to be successful in a short-term study.

To assess the feasibility, safety and efficacy of patient-led dosing using balsalazide in the long-term treatment of ulcerative colitis.

This was a 3-year, two-cohort, multi-centre study: one cohort was in stable remission (52 patients) and the other was newly in remission (76 patients) from ulcerative colitis. Two 750-mg balsalazide capsules were given twice daily for maintenance, increased by 750-mg increments to a maximum of 6 g for up to 7 days depending on symptom severity. Clinical assessments were made every 12-14 weeks; laboratory assessments were made every 6 months.

The average median daily dose of balsalazide was 3 g (range, 1.5-6 g). In the cohort with stable remission, 23 patients (44%) had relapsed by 3 years [median time to relapse, > 1095 days (36 months)]. In the cohort newly in remission, these values were 45 patients (59%) and 656 days (22 months), respectively. In the cohort with stable remission, the time since last relapse was significantly associated with relapse during the first year of treatment (P < 0.033).

Long-term, patient-led, maintenance treatment with balsalazide is well tolerated with a good safety profile and is effective for patients with ulcerative colitis.
