Product Description:

Cholestyramine, written colestyramine in European texts, is a strongly basic anion-exchange resin: a styrene-divinylbenzene copolymer carrying quaternary ammonium groups, in the chloride form. It is not absorbed. In the intestine it swaps chloride for bile acids and holds them in an insoluble complex that leaves in the faeces. This page covers the API, a fine powder or granules for making oral powder for suspension. Because the resin itself is the active, quality is defined by exchange capacity and assay on the dried basis.

The finished product is licensed for primary hypercholesterolaemia and for pruritus linked to partial biliary obstruction, and some markets include bile acid diarrhoea. It is also used to speed removal of leflunomide or teriflunomide. The powder is always mixed with water or another drink, never swallowed dry. It binds many other medicines, which are taken at least an hour before or four to six hours after a dose. Long-term use can impair absorption of vitamins A, D, E and K.

Sourcing notes. Specify the grade you need, USP Cholestyramine Resin or Ph. Eur. colestyramine. Ask for a DMF or CEP where available, a GMP certificate for the API site and a CoA per batch covering exchange capacity, loss on drying, chloride content, particle size and the other monograph tests. The resin takes up moisture, so it ships in lined, sealed drums at room temperature. As an API it does not carry CE marking. State grade, particle size, quantity, packaging, retest period and the dossier support your finished product needs.

Cholestyramine — third party manufacturing & bulk supply

Cholestyramine is available through PharmaTradz for wholesale and bulk supply as well as on a third party (contract) manufacturing basis. Buyers sourcing this product generally take one of three routes:

Wholesale / bulk supply Stock or scheduled supply from an existing manufacturer. The fastest route where the product is already registered in your market.

Third party manufacturing Manufactured to your specification and packed under your own brand and label — suits distributors and brand owners building a portfolio in their market.

Dossier licensing Where a CTD, EU-CTD or ACTD dossier exists it can often be licensed for filing in your name, compressing market entry from years to months.
