Why are meglitinides better tolerated than sulfonylureas?

Why are meglitinides better tolerated than sulfonylureas?

Another advantage of meglitinides is their flexibility compared with sulfonylureas because of their faster onset and shorter duration of action (Pfeiffer & Klein, 2014).

Why are second generation sulfonylureas preferred over first generation sulfonylureas?

They may also have other extra-pancreatic hypoglycemic actions that are important during prolonged therapy. The second generation sulfonylureas have largely replaced the first generation agents in routine use, because they are more potent, can be administered in lower doses, and can be given on a once daily basis.

How does the meglitinides differ from the sulfonylureas?

The main difference between sulfonylureas and meglitinides is that meglitinides have a rapid onset of action as well as a short duration of activity. This makes meglitinides ideal for patients with postprandial hyperglycemia. Thus these drugs are taken just before meals to reduce postprandial hyperglycemia.

What do second generation sulfonylureas do?

The second-generation sulfonylureas include glipizide (Glucotrol and Glucotrol XL), glyburide (Diabeta, Micronase, and Glynase PresTab), and glimepiride (Amaryl). These drugs are effective in rapidly ‘lowering blood sugar but run the risk of causing hypoglycemia.

How much do Meglitinides lower A1C?

Meglitinides reduce A1C levels by about 0.4% to 0.9% compared with placebo, but robust data are sparse. Alpha-glucosidase inhibitors reduce A1C levels by about 0.8% compared with placebo. We found no reports of dangerous adverse effects.

Why are meglitinides not used?

This study has demonstrated that hypoglycemia, and not meglitinide use, is associated with increased mortality. We showed that meglitinide indirectly could induce long-term mortality rate of by increasing their risk of hypoglycemia. Many antihyperglycemic agents and risk factors will increase the risk of hypoglycemia.

Which is the best sulfonylurea?

Sulfonylureas (SUs) in oral combination therapy: A1. Modern SUs (glimepiride and gliclazide modified release [MR]) are effective and safe second-line agents in patients who have not achieved predecided glycemic targets with metformin monotherapy (Grade A; evidence level [EL] 1) A2.

Why are sulfonylureas and meglitinides grouped together?

Sulfonylureas and Meglitinides ( glinides) have a very similar mode of action which is why they are grouped together here. Sulfonylureas are the first oral antidiabetic agents and can be divided into several generations.

When to take sulfonylureas and meglitinides for type 2 diabetes?

Sulfonylureas and meglitinides are recommended for persons with type 2 diabetes who have poorly controlled blood glucose levels. On average, most patients find that their Hb A1c levels drop by up to 1.5% on these medications.

Which is better for glycemic control sulfonylureas or metformin?

Compared with newer, more expensive agents (thiazolidinediones, alpha-glucosidase inhibitors, and meglitinides), older agents (second-generation sulfonylureas and metformin) have similar or superior effects on glycemic control, lipids, and other intermediate end points. Large, long-term comparative …

What happens if you skip a meal with sulfonylureas?

Sulfonylureas can cause low blood glucose, or hypoglycemia, if the patient skips a meal. This tends to occur in patients who are older or have kidney disease. Patients with worsening kidney function may need to reduce their dose or stop these medications to avoid hypoglycemia
