The market taxonomy further distinguishes cholestyramine by type, primarily into powder, tablet, and oral suspension formulations. The powder variant, supplied in bulk sachets for compounding, dominates with an estimated 55 % share due to its flexibility in dose titration for pediatric patients and cost advantage in chronic regimens. Within powder, sub‑categories include standard‑strength (4 g per dose) and high‑strength (8 g per dose) blends, each aligning with disease severity. Tablet formulations, engineered for adult compliance, represent roughly 30 % of sales; they are available in low‑dose (4 g) and high‑dose (8 g) tablets, offering precise dosing and improved adherence in specialty clinics. The oral suspension—a pre‑mixed liquid—covers about 15 % of the market, catering to patients with swallowing difficulties and enabling accurate pediatric dosing via calibrated syringes. These type‑based segments collectively define the market’s product architecture and influence pricing dynamics, reinforcing the analytical framework of Progressive Familial Intrahepatic Cholestasis Cholestyramine Treatment segmentation.
