The economics of mesalazine in active ulcerative colitis and maintenance in the Netherlands.

چکیده
BACKGROUND In this study we investigate the costs and benefits of topical mesalazine combined with oral mesalazine therapy for active ulcerative colitis (UC), and once daily (OD ) mesalazine 2 grams versus twice daily (BID ) for maintaining UC remission. METHODS Two decision analytic models were constructed to evaluate treatment costs and quality-adjusted life years (QALYs) associated with mesalazine. The first model explored 4 g oral mesalazine in combination with 1 g topical mesalazine during active UC compared with 4 g oral mesalazine monotherapy for achieving clinical remission. The second model compared remission rates at one year for OD 2 g oral mesalazine compared with BID 1 g adjusted for compliance. All direct costs were obtained from established treatment costs in the Netherlands. RESULTS The average cost of treatment to transition an active UC patient into remission using oral plus topical mesalazine or oral mesalazine monotherapy was v2207 (95% CI: v1402 to v3332) and v2945 (95% CI: v1717 to v4592), respectively. The annual average cost-saving of adding topical mesalazine delivered for four weeks during active UC was v738. The average annual costs of maintenance of remission with OD and BID therapy were v1293 (95% CI: v1062 to v1496) and v1502 (95% CI: v1262 to 1708), respectively with an annual average per person savings of v209. CONCLUSION Topical mesalazine during acute UC flares results in lower costs due to reduced healthcare consumption attributed to faster symptom resolution. Furthermore, as a result of lower costs and modest QALY gains, maintenance therapy using OD mesalazine is the dominant treatment option if compared with BID mesalazine.

The effects of crocin, mesalazine and their combination in the acetic acid-induced colitis in rats
Crocin, as a carotenoid compound of saffron, exerts a potent antioxidant property. Mesalazine is frequently used in the treatment of ulcerative colitis. This study investigated the effects of separated and combination treatments with crocin and mesalazine in a rat model of ulcerative colitis. Ulcerative colitis was induced by intra-colonic administration of acetic acid (4.00%, 1.00 mL) at 8 cm ...
متن کاملCost and quality-adjusted life year differences in the treatment of active ulcerative colitis using once-daily 4 g or twice-daily 2g mesalazine dosing.
BACKGROUND Improved compliance in active ulcerative colitis (UC) is likely to improve healthcare efficiency by reducing time spent in active mild to moderate UC state. To establish whether once daily (OD) mesalazine offers economic advantages over twice daily (BD) dosing in active UC, we evaluated the outcomes and costs of a recently published randomized study. METHODS A cost-effectiveness mo...

BACKGROUND AND AIM Left-sided colitis is the most prevalent subtype of ulcerative colitis, a chronic inflammatory disease of the colon. The standard of care for mild-to-moderate ulcerative colitis is mesalazine. The PODIUM study compared a once daily to a twice daily dosing regimen of a slow-release mesalazine (Pentasa®); here we assess the efficacy, in terms of maintenance of remission and muc...

INTRODUCTION A previous randomised controlled trial has demonstrated that oral plus topical mesalazine enema is more effective than oral mesalazine alone for achieving clinical remission in mild-to-moderately active extensive ulcerative colitis (UC). To evaluate whether this strategy is cost-effective we conducted an economic evaluation comparing 1 g topical mesalazine in combination with 4 g o...
