| 50 mcg/hr | High-strength dose; requires close monitoring. |
| 75 mcg/hr | Advanced pain management in palliative care. |
| 100 mcg/hr | Optimum basic patch strength. |

These are utilized 'as required,' but with strict limitations on frequency.
| Formulation Type | Common Strengths (mcg) | Administration Route |
|---|---|---|
| Sublingual Tablet (e.g., Abstral) | 100, 200, 300, 400, 600, 800 | Under the tongue |
