|---|---|---|---|
| Nasal Spray | 5-- 10 Minutes | 1-- 2 Hours | Fast relief, bypasses GI system |
| Oral (Liquid/Tablet) | 30-- 60 Minutes | 4-- 6 Hours | Ease of use for stable discomfort |
| Transdermal (Patch) | 12-- 24 Hours | 72 Hours | Consistent baseline pain control |

| Primary Use | BTCP in cancer clients | BTCP in cancer clients |
| Key Advantage | Decreased post-nasal drip | Wide range of dose increments |
Administration and Dosage Titration

- Tracking: The patient monitors the level of discomfort relief over 30 minutes.
- Escalation: If the pain is not controlled, the clinician might increase the dosage for the next breakthrough episode.
