The initial studies in acute Crohn's disease showed that budesonide capsule
s (Entocort(R)) were better tolerated than prednisolone and that the system
ic glucocorticosteroid effects, including the cosmetically important facial
changes, were significantly less frequent at similar clinical efficacy. In
the long-term studies and in the prolongation of remission studies, there
was a low, dose-dependent incidence of systemic effects while the time to r
emission was significantly prolonged. In the study comparing the efficacy a
nd safety of 5-aminosalicylic acid (5-ASA, Pentasa(R)) over 16 weeks, the s
erious adverse events and the discontinuations due to adverse events were l
ess frequent in the budesonide capsule group. The postmarketing reports sho
w a low frequency of such adverse events and the profile is that of a gluco
corticosteroid. In summary, budesonide capsules seem to be well tolerated i
n treatment of Crohn's disease affecting the ileum and/or ascending colon a
nd to have a good balance between the effect and the side effect profile, b
oth in comparison with prednisolone and 5-ASA. (C) 2000 Prous Science. All
