Diabetes Flashcards

1
Q

What are the actions of GLP-1

A

Enhances glucose-dependent insulin secretion

Slows gastric emptying

Suppresses glucagon secretion

Promotes satiety

Possibly improves insulin sensitivity.

Q

What are the recommendations for treatment of Type 2 Diabetes?

A

Initiate metformin therapy along with lifestyle interventions at diagnosis.

In newly diagnosed patients with markedly elevated blood glucose levels, consider insulin therapy.

If non-insulin therapy does not achieve A1C target over 3 months, add a second oral agent, a GLP-1 receptor agonist or insulin.

Q

What does metformin do? Why is it first line?

A

It activates hepatic AMP-kinase, which decreases hepatic glucose production.

It is first line, because it causes no weight gain or hypoglycemia, and reduces cardiovascular events and mortality.

Contraindicated in reduced kidney function.

Q

What do the sulfonureas do? What are the side-effects?

A

They close the potassium-ATP channels on beta-cell plasma membranes. This results in increased insulin secretion and reduced cardiovascular events/mortality.

Side effects: hypoglycemia and weight gain.

Q

What do the meglitinides do? When are they used? Side effects?

A

They close the potassium-ATP channels on beta-cell plasma membranes, resulting in increased insulin secretion. They are used before each meal.

Side effects: hypoglycemia and weight gain.

Q

What do the thiazolidinediones do? What is it used for?

A

It activates PPAR-alpha, which increases peripheral insulin sensitivity.

It raises HDL and lowers triglycerides, without causing hypoglycemia.

Q

What do Acarbose and Miglitol do? What are the side-effects?

A

They inhibit alpha-glucosidase, which inhibits carbohydrate breakdown and delays its GI absorption, while reducing post-prandial glucose.

Side effects: GI

Q

What do the GLP-1 receptor agonists do? Side effects?

A

They activate the GLP-1 receptor which increases insulin secretion and decreases glucagon secretion in a glucose dependent manner, slows gastric emptying and increases satiety.

Leads to weight reduction and may improve beta-cell mass.

Side effects: acute pancreatitis and GI

Q

What do the DPP-4 inhibitors do?

A

They inhibit GLP-1 breakdown, which increases insulin secretion and decreases glucagon secretion.

No hypoglycemia. Weight neutral.

17
Q

What is an SGLT2 inhibitor? What does it do? What are some side effects?

A

Canagliflozin.

It reduces glucose reabsorption in the kidney. and increases urinary glucose excretion.

Side effects: volume depletion, hyperkalemia and genital infections/UTIs.

18
Q

What is a bile acid sequestrant used for Type 2 Diabetes?

A

Colesevelam. Decreases cholesterol, but increases triglycerides.

19
Q

What is a DA2 agonist used (rarely) in Type 2 Diabetes? How does it work

A

Bromocriptine.

It alters hypothalamic regulation of metabolism and increases insulin sensitivity.
