Atenolol and pindolol interfere with urinary 5-hydroxyindole-3-acetic acid.
Oral beta-blockade with atenolol and pindolol was found to increase urinary 5-hydroxyindoleacetic acid (5-HIAA). In addition pindolol and perhaps some of its metabolites but not atenolol do interfere with chemical analysis of 5-HIAA. This may be due to structural similarities.
