Long acting insulin names?

Common long-acting (basal) insulin analogs:

- Insulin glargine
- Brand names: Lantus, Basaglar (biosimilar), Toujeo (glargine U-300)
- Typical duration: about 24 hours (Toujeo is more concentrated)

- Insulin detemir
- Brand name: Levimir
- Typical duration: roughly 24 hours

- Insulin degludec
- Brand name: Tresiba
- Typical duration: up to 42 hours (ultra-long-acting)

Notes:
- These are basal insulins used to provide steady background insulin.
- There are also combination products and country-specific brands.
If you’d like, tell me your country and I can tailor the brand names accordingly or include dosing notes.
