How Does Retatrutide 40 mg work?
Retatrutide is a single peptide formulated to activate 3 metabolic hormone receptors at once:
- GLP-1 receptor agonism: Slows gastric emptying, increases satiety signals to the brain, enhances glucose-dependent insulin secretion
- GIP receptor agonism: Enhances insulin secretion and may improve fat metabolism in preclinical models
- Glucagon receptor agonism: Increases energy expenditure and hepatic fat oxidation in research settings
Retatrutide works by mimicking 3 gut/ liver hormones to increase insulin, reduce appetite, slow digestion, and raise energy burn. This triple mechanism may produce the highest weight loss.
Usage
- It can be used in dealing with Type-2 Diabetes.
- It can be used in managing weight.
Dosage
- starting at 1-2mg once weekly, with gradual increases every 4 weeks up to 12mg once weekly.
- 40mg pen: A 40mg pen would be a multi-dose device.
- Do not self-titrate. Rapid dose escalation increases risk of GI side effects and pancreatitis.
Side Effects
- Constipation
- Abdominal pain
- Decreased appetite
- Nausea
- Diarrhea
- Vomiting
- Heartburn
- Flatulence
- Redness
- Itching
- Dizziness
Interactions
- It may interact adversely with other oral medications resulting in slowing gastric emptying this can delay absorption of other oral drugs.
- It also interacts with insulin/Sulfonylureas the concomitant use increases hypoglycaemia risk.
- Warfarin monitoring is need as it may affects the absorption.
- Alcohol may lead to increase the risk of other side effects.
Pharmacokinetics
- It may reach the peak plasma concentration Tmax at just 24-72 hours post Sub injection.
- Proteolytic degradation occurs to form small peptides and amino acids, similar to other GLP-1 peptides. This is followed by metabolism.
- Excretion, via kidney.
Precautions
- Personal/family history of medullary thyroid carcinoma or MEN2.
- History of pancreatitis, gallbladder disease, or severe GI disease.
- Type 1 diabetes or diabetic ketoacidosis history.
- Severe renal impairment dehydration risk.
- Pregnancy, planning pregnancy, or breastfeeding weight loss not recommended; fetal risk unknown.
