Blind comparison of patient preference for Flavored Colestid Granules and Questran Light.
OBJECTIVE
To compare the sensory and mixability characteristics of Flavored Colestid Granules (a new colestipol formulation) with Questran Light (the most recent cholestyramine formulation).


METHODS
Seventy-two nonsmoking adults between the ages of 25 and 64 years were enrolled in the study. Subjects assessed the sensory and mixability characteristics of each product in chilled bottled water and orange juice after at least a one-hour fast. Products were administered in a double-blind, randomized fashion. The sensory characteristics that were rated included overall rating, aftertaste, appearance, aroma, color, consistency, flavor, sweetness, mouthfeel, and thickness. Each characteristic was rated with a nine-point hedonic scale. Mixability of the products was assessed on a five-point scale. Subjects also were asked to choose which product they preferred as to sensory and mixability characteristics in each vehicle.


RESULTS
Fifty-three of the 72 subjects preferred the sensory characteristics of Flavored Colestid Granules in water (p < 0.001). Questran Light was preferred by 61 subjects when mixed in orange juice (p < 0.001). The sensory characteristic rating scores also supported subject preferences for Flavored Colestid Granules in water and Questran Light in orange juice. Mixability of Flavored Colestid Granules was rated significantly better (p < 0.001) than Questran Light in water. There was no significant difference for mixability between the products in orange juice.


CONCLUSIONS
Questran Light was significantly preferred on a sensory basis when mixed in orange juice. Flavored Colestid Granules was significantly preferred over Questran Light for both sensory and mixability characteristics with water as the vehicle.
