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

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

The Concept of Opioid Tolerance
