Interventie / Behandeling |
|---|---|
|
Experimenteel: Metformine
Metformine 2000 mg per dag
|
De sterkte van elke tablet is 500 mg.
De deelnemers bouwen gedurende vier weken op tot een dagelijkse dosis door gedurende 7 dagen één tablet per dag in te nemen, gedurende 7 dagen tweemaal daags één tablet, gedurende 7 dagen één tablet 's ochtends en 2 tabletten 's avonds en vervolgens 's ochtends 2 tabletten en 2 tabletten 's avonds, dagelijks gedurende de rest van de studiebehandelingsperiode.

Placebo-vergelijker: Orale Placebo
Een centrale apotheek zal een placebo samenstellen dat past bij de metforminetabletten. Het placeboproduct zal de volgende componenten bevatten:
