This study has shown that the treatment with pioglitazone was associated with a low incidence of hypoglycaemia. The factors possibly increasing the risk of hypoglycaemia were concomitant therapy with sulfonylurea or insulin and female gender.

This analysis shows that the frequency of reported hypoglycaemia within the study cohorts was relatively low. The rates of hypoglycaemia were not equal between drug classes. Treatment with nateglinide or repaglinide was characterized by a higher incidence of hypoglycaemia at the beginning of treatment. Further investigation is necessary to assess whether women treated with TZDs are more prone to hypoglycaemia than men. Findings from this study should be taken into account with other clinical and pharmacoepidemiological studies.
