摘要：
Disclosed are x-ray contrast compositions for oral or retrograde examination of the gastrointestinal tract comprising a polymeric material capable of forming a coating on the gastrointestinal tract and an x-ray producing agent of the formula
or a pharmaceutically acceptable salt thereof,
and methods for their use in diagnostic radiology of the gastrointestinal tract wherein
Z = H, halo, C 1 -C 20 alkyl, cycloalkyl, lower alkoxy, cyano, where the alkyl and cycloalkyl groups can be substituted with halogen or halo-lower-alkyl groups; R = C 1 -C 25 alkyl, cycloalkyl, or halo-lower-alkyl, optionally substituted with halo, fluoro-lower-alkyl, aryl, lower-alkoxy, hydroxy, carboxy lower-alkoxycarbonyl or lower-alkoxy-carbonyloxy, (CR 1 R 2 ) p -CR 3 =CR 4 ) m Q, or (CR, R 2 )p-C=C-Q; Ri, R 2 , R 3 and R 4 are independently lower-alkyl, optionally substituted with halo; x is 1-4; n is 1-5; m is 1-15; p is 1-10; and Q is H, lower-alkyl, lower-alkenyl, lower-alkynyl, lower-alkylene, aryl, or aryl-lower alkyl
in a pharmaceutically acceptable carrier.
