Diabetes medication brand and generic names
This list introduces common study examples rather than every diabetes medication or combination. Several ingredients also appear under brands used for other indications; those name overlaps are explained below.
Biguanides, sulfonylureas, and thiazolidinediones
| Brand name | Generic name | Class or type |
|---|---|---|
| Glucophage | metformin | Biguanides |
| Amaryl | glimepiride | Sulfonylureas |
| Glucotrol | glipizide | Sulfonylureas |
| Actos | pioglitazone | Thiazolidinediones |
DPP-4 and SGLT2 inhibitors
| Brand name | Generic name | Class or type |
|---|---|---|
| Januvia | sitagliptin | DPP-4 inhibitors |
| Farxiga | dapagliflozin | SGLT2 inhibitors |
| Jardiance | empagliflozin | SGLT2 inhibitors |
GLP-1 and GIP/GLP-1 receptor agonists
| Brand name | Generic name | Class or type |
|---|---|---|
| Trulicity | dulaglutide | GLP-1 agonists |
| Ozempic / Wegovy / Rybelsus | semaglutide | GLP-1 agonists |
| Mounjaro / Zepbound | tirzepatide | GIP/GLP-1 agonists |
Wegovy and Zepbound appear here to show shared ingredient names, not to label them as equivalent diabetes products. Ozempic and Rybelsus share semaglutide with Wegovy; Mounjaro shares tirzepatide with Zepbound.
Insulin examples
| Brand name | Generic name | Class or type |
|---|---|---|
| Humalog | insulin lispro | Insulin |
| NovoLog | insulin aspart | Insulin |
| Lantus / Basaglar / Toujeo | insulin glargine | Insulin |
| Tresiba | insulin degludec | Insulin |
Understanding diabetes medication classes
Metformin belongs to the biguanides. Glimepiride and glipizide belong to the sulfonylureas. Pioglitazone belongs to the thiazolidinediones, often abbreviated TZDs. Learn one clear example for each family before expanding the set.
DPP-4 means dipeptidyl peptidase-4; sitagliptin is a DPP-4 inhibitor. SGLT2 means sodium-glucose cotransporter 2; dapagliflozin and empagliflozin are SGLT2 inhibitors. The abbreviations are different, and so are the useful endings: -gliptin versus -gliflozin.
GLP-1 means glucagon-like peptide-1. Dulaglutide and semaglutide are GLP-1 receptor agonists. Tirzepatide is a dual glucose-dependent insulinotropic polypeptide (GIP) and GLP-1 receptor agonist. Keep that dual class label rather than learning tirzepatide as another insulin.
Insulin is its own family within this overview. The focused insulin guide breaks those names down further by type and explains why concentrations and product qualifiers matter.
Naming patterns and memory tips
Do not reduce all these endings to “gli- means diabetes.” Read the whole ending and retrieve the specific class. That is especially useful for glipizide and sitagliptin: their shared letters can distract from their different families.
Try a four-card contrast set: Januvia, Jardiance, Trulicity, and Actos. For each brand, recall the generic and class. Then add Glucophage—metformin as an example that does not fit those four suffix patterns.
- -gliptin: sitagliptin → Januvia → DPP-4 inhibitor.
- -gliflozin: dapagliflozin → Farxiga and empagliflozin → Jardiance → SGLT2 inhibitors.
- -glutide: dulaglutide → Trulicity and semaglutide → Ozempic, Wegovy, or Rybelsus → GLP-1 receptor agonists.
- -glitazone: pioglitazone → Actos → thiazolidinedione.
Commonly confused diabetes medication names
Semaglutide brands
Ozempic, Wegovy, and Rybelsus all connect to semaglutide. This is an ingredient association, not a statement that the brands have the same approved uses or formulations. Learn the shared generic first, then preserve the full product identity when your coursework asks for more detail.
Mounjaro and Zepbound
Both connect to tirzepatide, but they are distinct brands with different labeling. Do not confuse tirzepatide with semaglutide simply because the names appear in the same broader topic.
Glipizide and glimepiride
Glucotrol—glipizide and Amaryl—glimepiride are both sulfonylurea pairs. Learn them together once, then test them in a mixed set so the shared class does not substitute for recalling the correct name.
