Glucagon-Like Peptide-1 (Glp-1) Analogs Are A Group Of Medications That Are Used For Treating Type 2 Diabetes
Glucagon-Like Peptide-1 (Glp-1) Analogs
Glucagon-Like Peptide-1 Analogs are newer drugs used to treat type 2 diabetes. They regulate glucose levels by stimulating insulin secretion, suppressing glucagon release, and promoting satiety. These effects help control blood sugar, which can help prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function disorders.
Several
studies have shown that GLP-1 can also improve lipid metabolism, suppress
appetite, and increase fat loss in obese patients. These effects may lead to
weight loss and improvement of blood glucose control in type 2 diabetes
patients. According to Coherent Market

Peptide-1 (Glp-1) Analogs Market Global Industry Insights, Trends,
Outlook, and Opportunity Analysis, 2022-2028.
GLP-1
is produced by three different tissues, which include the enteroendocrine L
cells of the distal intestine, alpha cells in the central nervous system, and
the pancreas. It acts on the GLP-1 receptor to stimulate insulin secretion,
decrease glucagon release and reduce the release of fat from the liver. The
release of GLP-1 is stimulated by a wide range of stimuli such as food,
activity, and the hormone somatostatin.
The
GLP-1 receptor is located in many places throughout the body, including the
liver, heart, and stomach. When a person eats, GLP-1 is released from the intestine,
enters the blood circulation, and then activates the GLP-1 receptor.
In
a healthy person, GLP-1 is broken down by an enzyme called dipeptidyl
peptidase-4 in the gastrointestinal tract. In people with diabetes, the body
cannot break down enough GLP-1, so a drug is needed to produce more of it.
There
are 2 main types of GLP-1 agonists: long-acting (LGLP-1) and short-acting
(SGLP-1). Both work by increasing the release of GLP-1 from the intestine and
reducing glucagon secretion in the pancreas.
Exenatide,
exendin-4, and liraglutide are all available as injectable medications in the
United States and Europe. They are injected directly into the vein or stomach,
and they are effective for controlling blood sugar in patients who have not
improved with a single oral glucose-lowering agent or are on dual therapy.
A
randomized, placebo-controlled trial of a once-daily or twice-daily injection
of GLP-1 analogs in patients with type 2 diabetes and inadequate glycaemic
control on metformin or sulphonylurea has been conducted in the USA. The
results showed that the patients who received GLP-1 analogs had significantly
better glycaemic control than those who received the placebo or other
glucose-lowering agents.
The
Mounjaro (tripeptide) injection from Eli Lilly and Company gained approval
from the US FDA in May 2022. This injection can be used as an adjunct to diet
and exercise for enhancing glycemic control in adult patients suffering from
type 2 diabetes.
