Bile acid sequestrant (anion-exchange resin)
Identity: Cholestyramine resin
The USP monograph covers identity by infrared spectroscopy, pH, loss on drying, residue on ignition, dialyzable quaternary amines by UV-visible absorbance, chloride content by potentiometric titration, and exchange capacity by HPLC (glycocholate binding).

No. Cholestyramine resin does not fit the standard $250 identity, purity and quantity test, so it is tested to the USP Cholestyramine monograph. Pricing is quoted.
Cholestyramine is a cross-linked styrene and divinylbenzene polymer carrying quaternary ammonium groups in the chloride form. It is insoluble, so it is characterized by what it binds rather than by a molecular weight.
The USP assay measures exchange capacity, meaning how much bile salt a known weight of resin binds, by measuring what is left in solution by HPLC.
Usually a powder for oral suspension that contains sugar or sweeteners, flavors and other excipients. Tell us the product form so the binding test is set up correctly.
