sitagliptin-phosphate and Dyspepsia

Early initiation of combination therapy using antihyperglycemic agents is recommended for treating type 2 diabetes (T2D). The present multicenter double-blind randomized parallel-group study examined the efficacy and safety of a sitagliptin and metformin fixed-dose combination (Sita/Met) compared with glimepiride in T2D patients as initial treatment.. Type 2 diabetes patients (aged ≥18 years) were randomized to Sita/Met or glimepiride for 30 weeks after a wash-off run-in period. The primary endpoint was change from baseline (CFB) in HbA1c. Secondary endpoints included the proportion of patients achieving target goal (HbA1c < 7.0 % [53 mmol/mol]) and CFB in fasting plasma glucose (FPG). Safety assessments comprised weight gain from baseline and the incidence of adverse events (AEs).. In total, 292 patients were randomized to Sita/Met (n = 147) or glimepiride (n = 145). After 30 weeks, Sita/Met demonstrated superiority over glimepiride in reducing HbA1c (-1.49 % vs -0.71 %, respectively; between-group difference - 0.78 %; P < 0.001). A significantly higher proportion of patients achieved the target goal with Sita/Met (81.2 %) than with glimepiride (40.1 %; P < 0.001). Greater reduction in FPG occurred with Sita/Met than with glimepiride (least-squares mean difference - 23.5 mg/dL; P < 0.001). Both drugs were generally well tolerated. Hypoglycemia events and weight gain were significantly lower in patients with Sita/Met than with glimepiride (5.5 % vs 20.1 % and -0.83 vs +0.90 kg, respectively; both P < 0.001). No serious drug-related AEs or deaths were reported.. Compared with glimepiride, Sita/Met as an initial treatment led to significantly greater improvements in glycemic control and body weight changes, with a lower incidence of hypoglycemia, over 30 weeks.
