There is some ambiguity as to the exact structure of tegaserod. The structure shown here is PubChem match using the CAS number submitted to the WHO for the INN. Alternative structure renderings for tegaserod are numerous: PubChem CID 5362436
has the highest submitter consensus in PubChem but may not match renderings in references for the biological activity; CID 5487301
, and CHEMBL76370
are further alternatives.
Marketed formulations include tegaserod maleate (PubChem CID 6918369
)- again with the caveat of alternative representations.
