Group 2# These drugs reduce blood glucose without stimulating insulin production, therefore are insulin nonsecretogogues.# These durgs do not cuase hypoglycemia when used alone and can cause hypoglycemia, only when used with other oral hypoglycemics.# Examples are:i) Biguanides: Metformin, Phenforminii) Thiazolidinediones: Rosiglitazone, Pioglitazone, Troglitazone.iii) a-glucosidase inhibitors: Acarbose, miglital.", 'role': 'assistant'}]
