Laboratory Evaluations (Phase III)
Clinically relevant laboratory abnormalities in hematology and biochemistry values were rare and with similar frequency for tegaserod- and placebo-treated groups
Liver chemistries (LFTs)
- ALT > 3-fold normal: tegaserod 0.4% versus placebo 0.2%
- AST > 3-fold normal: tegaserod 0.1% versus placebo 0.1%
- No simultaneous elevations in ALT/AST and bilirubin
- No serious adverse event of hepatitis or elevated LFTs
- No evidence of tegaserod-induced hepatotoxicity was noted
