Methods of Administration
GLP-1 receptor agonists are strictly prescription drugs, and their administration methods vary depending on the specific dosage form, mainly covering the following guidelines:
* **Subcutaneous Injection (Mainstream Dosage Form):** Most GLP-1 RAs (such as semaglutide, liraglutide, dulaglutide, etc.) are administered subcutaneously using a pre-filled injection pen. Injection sites can be the abdomen, anterolateral thigh, or lateral upper arm, and these sites should be rotated regularly to avoid subcutaneous induration. Dosage frequency is once daily or once weekly.
* **Oral Administration (Emerging Dosage Form):** Newer generation oral GLP-1 RAs (such as oral semaglutide and ofoglitazone) are in tablet form. Oral semaglutide must be taken strictly in the morning on an empty stomach with no more than half a cup of water, and no food, water, or other medications should be taken for at least 30 minutes after administration to ensure absorption.
* **Dosage Titration Principle:** To reduce gastrointestinal adverse reactions, all GLP-1 RAs must follow the principle of "starting with a low dose and gradually increasing." Patients must strictly follow their doctor's instructions regarding dosage adjustments and must not increase the dosage or discontinue medication on their own.
Application Scenarios (Preclinical Research):
Glucose Metabolism and Type 2 Diabetes Mellitus (T2DM): Incretin effect, glucose-dependent insulin secretion, β-cell protection, DPP-4 resistance modification
Obesity and Energy Balance: Hypothalamic appetite circuit, gastric emptying, thermogenesis in fat/brown adipose tissue, weight loss models
Receptor Pharmacology: GLP-1R binding kinetics, cAMP bias vs. β-arrestin bias (e.g., biased Ecnoglutide studies)
Analogous/Multi-Agonist Development: Mono-agonist (Liraglutide/Semaglutide) → Bi-agonist (Tirzepatide GIP/GLP-1) → Tri-agonist (GLP-1/GIP/GCG) SAR and pharmacokinetic comparison
Neurology and Aging: Neuroprotection in AD/PD models, Aβ clearance, microglial regulation, retinal/fundus metabolic protection
Cardiovascular/Kidney/Hepatic: GLP-1R signaling assessment in atherosclerosis, heart failure, DKD, MAFLD
Storage Conditions
As a polypeptide biological agent, GLP-1RA is sensitive to temperature and environment and must be stored in strict accordance with the following cold chain storage guidelines:
Unopened (before first use): Must be stored in a medical refrigerated environment at 2°C to 8°C, protected from light. Freezing is strictly prohibited. If the drug freezes, it must be discarded and not used after thawing.
After opening (after first use):
Injectables: Can be stored at room temperature (not exceeding 30°C) or refrigerated at 2°C to 8°C, with the pen cap on to protect from light. The shelf life at room temperature varies for different drugs (e.g., dulaglutide 14 days, smegglutide 6 weeks); discard if the shelf life exceeds this period. Remove the needle after each use to prevent contamination and leakage.
Oral tablets: No refrigeration required; store at room temperature protected from light and moisture.
Drug Solution Inspection: Visually inspect before each injection. Use only when the solution is clear, colorless, and free of visible particles.
