All of the statements about exenatide are true except: 
Select and explain. 
A. It is a GLP–1 analogue, B. It can be used for treatment of Type 1 diabetes mellitus, C. It is given subcutaneously, D. It decreases glucagon
B: It can be used for treatment of Type 1 diabetes mellitus
Answer: B: It can be used for treatment of Type 1 diabetes mellitus 
Explanation: Exenatide (Exendin 4) is a GLP-1 receptor agonist that is more resistant to DPP-4 action and cleared by the kidney.
When this drug is given to patients with type 2 diabetes by subcutaneous injection twice daily, it lowers blood glucose and HbA1c levels. It is not indicated in type 1 diabetes.
Exenatide appears to have the same effects as GLP-1 on glucagon suppression and gastric emptying.
Only drugs approved for treatment of type 1 diabetes are insulin and pramlintide.
