Brief summary

To evaluate vildagliptin as compared to gliclazide, given in combination with metformin in Muslim patients with type 2 diabetes fasting during Ramadan.

Interventions

DRUGVildagliptin

Patients will be instructed to take Vildagliptin tablets at a fixed dose of 50 mg twice daily (double blind therapy)

DRUGGliclazide

Patients will be instructed to take Gliclazide capsules at an equivalent dose to previous sulfonylurea in multiples of 80mg only (double blind therapy)

DRUGMetformin

Patients in both arms will take Metformin at a dose between 1500mg-2500mg per day, in an open label fashion

DRUGPlacebo to Gliclazide

Patients will be instructed to take the Gliclazide matching placebo capsules at an equivalent dose to previous sulfonylurea in multiples of 80mg only (double blind therapy)

DRUGPlacebo to Vildagliptin

Patients will be instructed to take Vildagliptin matching placebo tablets at a fixed dose of 50 mg twice daily (double blind therapy).
