AbstractThe current study examines the impact of glipizide, a second-generation sulfonylurea, on diabetes control in patients in whom adequate control was not achieved while receiving treatment with first-generation agents. The interim results of this multicenter study are presented in which patients in whom euglycemia was not achieved based on fasting and two-hour postprandial plasma glucose criteria with first-generation sulfonylureas were given glipizide therapy for 24 weeks. Twenty-three percent of the patients who had only fair results with first-generation sulfonylureas (fasting plasma glucose level of more than 140 mg/dl, postprandial plasma glucose level of more than 175 mg/dl) had good to excellent results with glipizide therapy alone (fasting plasma glucose level of less than 140 mg/dl or less than 115 mg/dl, respectively). Overall, 15.4 percent of patients with fair to poor control using first-generation agents had good to excellent control using glipizide. At least a 25-mg/dl decrease in fasting plasma glucose and postprandial plasma glucose levels was also seen in 47 and 46 percent of patients given treatment with glipizide who had poor control (fasting plasma glucose level of more than 200 mg/dl, postprandial plasma glucose level of more than 235 mg/dl) with first-generation agents. Glipizide was extremely well tolerated, with no significant side effects. Preliminary data indicate that glipizide may provide a significant advantage in terms of safety and efficacy over first-generation agents.
