Scope and specificity of acarbose in slowing carbohydrate absorption in man

Fifty-gram carbohydrate tolerance tests were performed on healthy
volunteers to test the activity and specificity of an alpha-glucoside
hydrolase inhibitor, acarbose (BAY g 5421). Two hundred milligrams acarbose
reduced the area under the blood glucose response curve by 89% (P less than
0.001) after sucrose by 80% (P less than 0.002) after starch, by 19% (N.S.)
after maltose, with no effect on glucose. Breath hydrogen measurements
indicated an almost complete malabsorption of the sucrose. At 50 mg
acarbose, some reduction in blood glucose and insulin response to sucrose
was still seen, but no significant hydrogen production. It is suggested
that at lower doses, acarbose may prolong the time course over which
carbohydrate is absorbed as does dietary fiber; as with fiber, it may be a
useful adjunct to diabetic therapy.
