Delayed-release Multi Matrix System (MMX) mesalazine: in ulcerative colitis.
* Mesalazine appears to act locally on the mucosa of the colon and reduces the inflammation associated with ulcerative colitis. * Following oral administration, the majority (*78%) of a dose of delayed-release Multi Matrix System (MMX) mesalazine passes unabsorbed through the upper gastrointestinal tract to reach and traverse the entire length of the colon. * In a well designed phase III trial in patients with active, mild to moderate ulcerative colitis (n = 262), significantly (p < 0.01) more MMX mesalazine 2.4 (34%) or 4.8 g/day (29%) recipients than placebo recipients (13%) achieved clinical and endoscopic remission after 8 weeks of treatment.* In a second phase III trial (n = 341), clinical and endoscopic remission rates with MMX mesalazine 2.4 (40.5%) and 4.8 g/day (41.2%) were significantly (p < 0.01) greater than with placebo (22.1%) after 8 weeks, while the remission rate with non-MMX delayed-release mesalazine (Asacol) [32.6%] did not differ from placebo.* Overall, MMX mesalazine was generally well tolerated in controlled clinical trials, with a similar incidence of treatment-emergent adverse events in placebo (66%) and MMX mesalazine (56%) recipients in a pooled analysis; most adverse events were of mild or moderate severity. Two of 434 MMX mesalazine recipients experienced serious adverse events that were considered treatment related (pancreatitis caused by mesalazine sensitivity).
