Input: Fifteen trials involving 3781 participants were included. No studies reported the effect of meglitinides on mortality or morbidity. In the eleven studies comparing meglitinides to placebo, both repaglinide and nateglinide resulted in a reductions in glycosylated haemoglobin (0.1% to 2.1% reduction in HbA1c for repaglinide; 0.2% to 0.6% for nateglinide). Only two trials compared repaglinide to nateglinide (342 participants), with greater reduction in glycosylated haemoglobin in those receiving repaglinide. Repaglinide (248 participants in three trials) had a similar degree of effect in reducing glycosylated haemoglobin as metformin. Nateglinide had a similar or slightly less marked effect on glycosylated haemoglobin than metformin (one study, 355 participants). Weight gain was generally greater in those treated with meglitinides compared with metformin (up to three kg in three months). Diarrhoea occurred less frequently and hypoglycaemia occurred more frequently but rarely severely enough as to require assistance. Meglitinides may offer an alternative oral hypoglycaemic agent of similar potency to metformin, and may be indicated where side effects of metformin are intolerable or where metformin is contraindicated. However, there is no evidence available to indicate what effect meglitinides will have on important long-term outcomes, particularly mortality.
Output:

No studies reported the effect of meglitinides on mortality or diabetes related complications. In the eleven studies comparing meglitinides to placebo, both repaglinide and nateglinide resulted in an improved blood sugar control. Weight gain was generally greater in those treated with meglitinides compared with metformin (up to three kg in three months), another oral antidiabetic drug. Here, diarrhoea occurred less frequently and hypoglycaemia occurred more frequently but rarely severely enough as to require assistance.  Meglitinides may offer an alternative oral hypoglycaemic agent of similar potency to metformin, and may be indicated where side effects of metformin are intolerable (in particular persistent diarrhoea) or where metformin is contraindicated. However, there is no evidence available yet to indicate what effect meglitinides will have on important long-term outcomes, in particular, on mortality. As yet, the experience with meglitinides in terms of side effects is limited. Results from other Cochrane review groups may provide additional information about the potential role of meglitinides in the management of type 2 diabetes mellitus.
