T2D Medicine Incretin Byetta

Byetta is only for those with type 2 diabetes who takes metformin, a sulfonylurea, or both. Enhance insulin secretion in the presence of high blood glucose.

GLP-1 agonists are a class of drugs for type 2 diabetes treatment. The advantage of this drug over older insulin secretagogues is a lower risk of hypoglycemia.

GLP-1 agonists’ mechanism of action

The GLP-1 agonist is believed to improve glucose control by;

  • It increases insulin secretion by the pancreas in response to eating meals; once blood glucose decreases, insulin production decreases proportionally.
  • It suppresses the pancreatic glucagon release in response to eating, so stops unneeded glucose dumping in the bloodstream.
  • It slows down gastric emptying, thus minimizes glucose spikes in the bloodstream.

GLP-1 agonists available on the market:

  • Generic name: exenatide (Brand name: Byetta),
  • Generic name: liraglutide (Brand name: Victoza).

GLP-1 agonists’ dosage

GLP-1 agonists should start with 5 mcg administered twice daily within the 60-minute before the two major meals with a minimum 6 hours apart. It should not take after a meal. If necessary, you can increase the dose to 10 mcg twice daily after one month of therapy; this is to reduce to gastrointestinal side effects.

Side effects of GLP-1 agonists

The significant side effects of GLP-1 agonists are gastrointestinal;

acid or sour stomach,

belching,

diarrhea,

heartburn,

indigestion,

nausea, and

vomiting.

What can you expect for GLP-1 agonists?

In patients with type 2 diabetes, it can lower A1C of up to 1.1% sustained the HbA1c reduction with continued use of the medicine over a year. It also reduces fasting blood-glucose level and body weight (up to 5 pounds). A study has shown GLP-1 agonists can help achieve an A1C of less than 7%.

Who can benefit from GLP-1 agonists?

It is beneficial for diabetes type 2, who are overweight; it can reduce weight as well as lower your blood glucose level as well as A1C without causing hypoglycemia.

Who should avoid using GLP-1 agonists?

Patients with a history of pancreatitis consider using other anti-diabetic therapies. When taken along, sulfonylurea may increase hypoglycemia risk. So, try to reduce your dose of sulfonylurea. GLP-1 agonists are unsuitable for patients with a severe gastrointestinal disease such as gastroparesis. GLP-1 agonists should not use in patients without renal impairment.
