Identification

Name
Exenatide
Accession Number
DB01276
Description

Exenatide is a glucagon-like peptide-1 (GLP-1) analogLabel. It functions to activate the GLP-1 receptor and increases insulin secretion, decrease glucagon secretion, and slow gastric emptying to improve glycemic controlLabel. Exenatide was given FDA approval on April 28, 20054.

Pharmacology

Indication

Exenatide is indicated for improving glycemic control in adults with type 2 diabetes mellitus along with diet and exerciseLabel.

Pharmacodynamics

When patients take exenatide the body's natural response to glucose is modulatedLabel. More insulin and less glucagon are released in response to glucose, though in cases of hypoglycemia a normal amount of glucagon is releasedLabel. Exenatide also slows gastric emptying, leading to a slower and prolonged release of glucose into the systemic circulationLabel. Together these effects prevent hyper and hypoglycemiaLabel.

Mechanism of action

Exenatide is a human glucacon-like peptide-1(GLP-1) receptor agonistLabel. By activating this receptor, insulin secretion is increased and glucagon secretion is decreased in a glucose dependant mannerLabel. Exenatide also slows gastric emptying and decreases food intakeLabel. These effects work synergistically to improve glycemic control by reducing the likelihood of hyper and hypoglycemiaLabel.

Absorption

Exenatide reaches a peak plasma concentration in 2.1 hoursLabel. Because exenatide is administerd subcutaneously, the bioavailability is 11.

Volume of distribution

28.3LLabel.

Protein binding

Protein binding of exenatide has not been determined5.

Metabolism

Exenatide is filtered through the glomerulus before being degraded to smaller peptides and amino acids by dipeptidyl peptidase-4, metalloproteases, endopeptidase 24-11, amino proteases, and serine proteasesLabel,3. It is currently believed that the metalloproteases are responsible for most of the degradation of exenatide3. Exenatide is metabolised to small peptides <3 amino acids in length by enzymes in the kidney2.

Route of elimination

Exenatide is mainly eliminated by glomerular filtration followed by proteolysis before finally being eliminated in the urineLabel,2.

Half-life

2.4 hoursLabel

Clearance

9.1 L/hourLabel.

Toxicity

In animal studies, exenatide was associated with fetal deformities of ribs and vertebrae as well as slowed growthLabel. In humans, uncontrolled hyperglycemia can be associated with an up to 25% risk of miscarriageLabel. No human studies in pregnancy have been performed with exenatide and so exenatide should only be prescribed in pregnancy if the benefit to the mother and fetus outweigh the risksLabel. In mice, exenatide is excreted in the milk at a concentration 2.5% of the plasma concentration though this data may not be applicable to humansLabel. The effect of exenatide on breastfed infants is also unknown and so the risk and benefit of breastfeeding while taking exenatide must be weighedLabel. There is no data for the use of exenatide in pediatric patientsLabel. Geriatric patients do not have different results for safety and efficacy of exenatide though caution should still be used in this group as they are at higher risk of renal impairment or other comorbidities that may affect the liklihood of adverse effectsLabel. No dosage adjustments are necessary for patients with creatinine clearance ≥50mL/min, though prescribing to patients with creatinine clearance 30-50mL/min should be done cautiouslyLabel. Exenatide is not recommended for patients with creatinine clearance <30mL/minLabel. Hepatic impairment is not expected to affect clearance of exenatide though no studies have been performed to confirm thisLabel.
