The present invention provides pyrazole derivatives represented by the
general formula: ##STR00001## wherein R.sup.1 represents H, an
optionally substituted C.sub.1-6 alkyl group etc.; one of Q and T
represents a group represented by the general formula: ##STR00002## or a
group represented by the general formula: ##STR00003## while the other
represents an optionally substituted C.sub.1-6 alkyl group etc.; R.sup.2
represents H, a halogen atom, OH, an optionally substituted C.sub.1-6
alkyl group etc.; X represents a single bond, O or S; Y represents a
single bond, a C.sub.1-6 alkylene group etc.; Z represents CO or
SO.sub.2; R.sup.4 and R.sup.5 represent H, an optionally substituted
C.sub.1-6 alkyl group etc.; and R.sup.3, R.sup.6 and R.sup.7 represent H,
a halogen atom etc., pharmaceutically acceptable salts thereof or
prodrugs thereof, which exhibit an excellent inhibitory activity in human
SGLT1 and are useful as agents for the prevention or treatment of a
disease associated with hyperglycemia such as diabetes, diabetic
complications or obesity, and pharmaceutical compositions comprising the
