In adults with overweight or obesity, taking weekly pemvidutide at doses up to 2.4 mg for 48 weeks is linked to only small increases in heart rate and no meaningful changes in blood sugar or HbA1c...
Mechanism
Synthesis from 1 study
This medicine helps people lose weight by making the liver burn fat and the brain feel full, but it doesn’t mess up blood sugar because it only triggers insulin when needed. The heart rate barely goes up because the part that burns fat doesn’t strongly signal the heart to beat faster.
Most probable mechanism
This medicine activates two receptors in the body: one that tells the brain to feel full and helps keep blood sugar steady, and another that makes the liver burn more fat for energy. The blood sugar stays stable because the first receptor helps the pancreas release just the right amount of insulin when needed, without overdoing it. The heart rate goes up only a little because the second receptor doesn’t strongly stimulate the heart, even though it boosts energy use elsewhere.
Pemvidutide binds to GLP-1 receptors on pancreatic beta cells, enhancing glucose-dependent insulin secretion without causing excessive insulin release during fasting states
Pemvidutide binds to GLP-1 receptors in the hypothalamus, reducing appetite and food intake, which contributes to weight loss without directly altering glucose metabolism
Pemvidutide activates glucagon receptors on hepatocytes, increasing hepatic glucose production and fat oxidation to support energy expenditure during weight loss
Glucagon receptor activation does not significantly stimulate cardiac beta-adrenergic pathways, resulting in only minor increases in heart rate despite elevated metabolic demand
The combined effects of GLP-1-mediated insulin regulation and glucagon-mediated metabolic shift maintain fasting and postprandial glucose levels within normal ranges despite significant weight loss
