| Strength (micrograms/hour) | Use Case |
|---|---|
| 12 mcg/hr | Standard beginning dose for opioid-tolerant patients. |
| 25 mcg/hr | Moderate dosage for escalating chronic pain. |
| 50 mcg/hr | High-strength dose; needs close tracking. |
| 75 mcg/hr | Advanced pain management in palliative care. |
| 100 mcg/hr | Maximum basic spot strength. |

These are used 'as required,' however with stringent limits on frequency.
| Solution Type | Typical Strengths (mcg) | Administration Route |
|---|---|---|
| Sublingual Tablet (e.g., Abstral) | 100, 200, 300, 400, 600, 800 | Under the tongue |

The Concept of Opioid Tolerance
