[Lithogenicity and bile acid pattern in choleretic administration (3-n-butoxy-1-phenoxy-propanol: febuprol) in patients with functional right upper quadrant pain].

10 patients with right upper quadrant pain were treated with a choleretic agent (Febuprol; 3 X 200 mg t. i. d.) and placebo in a cross-over double dummy technique for 16 weeks. Lithogenic index, bile acid profile and serum lipids were determined every 4 weeks. During Febuprol application the clinical symptoms were relieved (0.87 +/- 1.3 vs. 1.39 +/- 0.21 (placebo); p less than 0.05, semiquantitative score). Biliary lithogenicity (1.45 +/- 0.6 vs. 1.09 +/- 0.12; n. s.), bile acid profile and serum lipids showed no statistically significant change, although serum cholesterol levels seemed to fall during Febuprol application.
