Comparison: PT-141 Administration Routes
Subcutaneous injection ~75–80% 60–90 minutes Moderate (systemic circulation → BBB crossing) Gold standard. Requires injection technique. Local site reactions common. Intranasal (olfactory) 7–10% 30–45 minutes High (direct olfactory pathway) Technique-dependent

- Subcutaneous injection
- ~75–80%
- 60–90 minutes
- Moderate (systemic circulation → BBB crossing)
- Gold standard. Requires injection technique. Local site reactions common.
- Intranasal (olfactory)
- 7–10%
- 30–45 minutes
- High (direct olfactory pathway)
- Technique-dependent. Requires proper head position and formulation. Mucosal irritation possible.
- Oral (tablet/capsule)
- <1%
- Not applicable
- Negligible
- Destroyed by gastric acid and hepatic metabolism. Clinically ineffective.
- Sublingual
- 2–4%
- 45–60 minutes
- Low
- Better than oral, but still faces enzymatic degradation. No direct CNS pathway.
