List of GLP-1 Medications & Agonist Drug Classes
A plain-language overview of GLP-1 receptor agonist medications — sometimes called GLP-1 RA drugs or glucagon-like peptide-1 agonists — including semaglutide, tirzepatide, liraglutide, and dual-agonist options.
Understanding GLP-1 Agonist Drug Classes
"GLP-1 agonist," "GLP-1 RA medication," and "glucagon-like peptide-1 agonist" all refer to the same broad drug category. Below is a general reference — not a recommendation for any specific product.
| Active ingredient / class | Mechanism | Common use area | Administration | Considerations |
|---|---|---|---|---|
| Semaglutide-based medications | GLP-1 receptor agonist | Type 2 diabetes and/or weight management, depending on formulation | Injectable; some oral tablet forms exist | Approval, brand, and dosing schedule vary by indication |
| Tirzepatide-based medications | GIP/GLP-1 dual receptor agonist | Type 2 diabetes and/or weight management, depending on formulation | Injectable | Acts on two hormone pathways; often requires gradual dose titration |
| Liraglutide-based medications | GLP-1 receptor agonist | Type 2 diabetes and/or weight management, depending on formulation | Injectable, typically daily | One of the earlier GLP-1 options; dosed more frequently than newer drugs |
| Other/emerging GLP-1 and dual-agonist candidates | GLP-1 receptor agonist or multi-hormone agonist | Varies by drug and approval stage | Varies | Approval status changes over time; confirm current status with your provider |
Medication availability, FDA approval, indications, prescription requirements, and individual eligibility vary and may change. This table is general education only and is not a recommendation for any specific product, brand, or dosage. It does not include every GLP-1 agonist on the market.
GLP-1 vs. "GLP-1 Inhibitors"
You may see the term "GLP-1 inhibitor" used online. In the context of these treatments, the relevant drug class is a GLP-1 receptor agonist — meaning it activates the GLP-1 receptor rather than blocking it. A qualified provider or pharmacist can clarify terminology for any specific product you're asking about.
Medications List — Common Questions
A GLP-1 receptor agonist is a medication that mimics glucagon-like peptide-1, a hormone that helps regulate appetite, digestion, and blood sugar.
Semaglutide is one specific active ingredient within the broader GLP-1 receptor agonist drug class — not the only one. Other GLP-1 medications use different active ingredients.
A dual agonist, such as tirzepatide-based medication, acts on both the GLP-1 and GIP hormone pathways rather than GLP-1 alone, which can affect dosing and clinical use.
Approved medications and brand names change over time. Your prescribing provider or pharmacist has the most current, complete list relevant to your location and situation.
