Efficacy of Oral HA35 for Rapid Relief of Oral Pain and Pungent Sensation

Descrição detalhada
This prospective, single-center, open-label, controlled pilot clinical study evaluates the rapid analgesic and anti-pungent effects of oral 10% 35 kDa hyaluronan (HA35) compared with two control interventions in healthy adults with capsaicin/AITC-induced oral pain and pungent sensation.
Eligible participants undergo standardized pain induction:
Capsaicin (chili) challenge: Oral capsaicin exposure induces oral pain. AITC (wasabi/horseradish) challenge: Oral AITC exposure induces pain and pungency.
After induction, participants are assigned to 6 parallel groups:
HA35:20 mL 10% HA35 oral solution Control 1:20 mL 4 mg/L C60 grapeseed oil Control 2:20 mL normal saline All interventions administered orally, held 3-30 seconds then swallowed.
Outcome assessments:
Oral pain (0-10 NRS) Pungent/irritant sensation (0-10 NRS) Time points: Baseline, 30 sec, 60 sec, 120 sec Safety: Oral adverse events and tolerability monitored throughout. Minimal-risk, non-invasive oral intervention. All procedures follow Declaration of Helsinki; written informed consent obtained.

Prazo |
|---|---|---|
|
Change in Oral and Upper-Airway Discomfort Intensity After Horseradish Stimulation (0-10 NRS)
Prazo: Baseline and 3 seconds and 30 seconds after treatment.
|
Change in overall oral and upper-airway discomfort induced by commercially available horseradish, assessed using an 11-point Numerical Rating Scale (NRS) ranging from 0 to 10, where 0 indicates no pain or irritation-related discomfort and 10 indicates the worst imaginable pain or irritation.
The assessed sensation includes oral and lingual pain, nasal pungency, pharyngeal irritation, and cough-related discomfort.
|
Baseline and 3 seconds and 30 seconds after treatment.
