The Effectiveness and Safety of Mucoadhesive Film Containing A.Oleracea Extract

Not Applicable

• Conditions: Oral Mucosa
• Interventions: Other: Mucoadhesive film containing Acmella oleracea extract; Other: Mucoadhesive film without Acmella oleracea extract

• Registration Number: NCT05219747
• Lead Sponsor: Khon Kaen University

Brief Summary

Several natural products have been use to promote wound healing and relieve pain. Acmella oleracea has a component that has anesthetic and anti-inflammatory properties.

The mucoadhesive film can be improved by drug delivery system due to close contact with the absorption tissue leading to improvement in both local and systemic effects.

This study aims to evaluate the effectiveness and safety of mucoadhesive film containing Acmella oleracea extract in healthy subjects. This is a randomised, double-blind (participant and investigator), parallel-controlled clinical trial. In total, approximately 72 subjects will be enrolled into study.

Objectives

1. To investigate the potential of skin allergy reaction to mucoadhesive film containing Acmella oleracea extract in healthy subjects

2. To study the duration of mucosal adhesion of mucoadhesive film

3. To study the local anesthetic effect, participant's satisfaction and adverse effect of mucoadhesive film containing Acmella oleracea extract

Detailed Description

Total 72 Participants will divided into 2 groups by dentist who was not an examiner performed the randomization using blocked randomization (block of 4) from program of https://www.sealedenvelope.com/simple-randomiser/v1/lists/1. Study group will receive mucoadhesive film containing Acmella oleracea extract while control group will receive mucoadhesive film without active component. All participants in the study group will be test for allergic reaction of mucoadhesive film by skin prick test and patch skin test before testing and have to follow-up appointments (at 2, 4 and 7 days after skin test). At first visit, all participants will received oral examination and informed how to use mucoadhesive film by examiner. Then participants will asked to apply the mucoadhesive film at oral mucosa of lower lip. The effectiveness of intra-oral mucoadhesive film in this study will evaluated as follows :

1. Duration of mucosal adhesion and adverse effect by self report

2. The local anesthetic effect by using Numeric rating scale (NRS)

3. Participant's satisfaction by using Numeric rating scale (NRS)

The statistical methods :

General and oral health data, duration of mucosal adhesion will reported as frequencies, percentages and means (Standard deviation). The different of NRS score between groups will analyzed Independent t- test or Mann-Whitney U test. Using SPSS software. Statistically significant will considered at p-value \< 0.05.

To investigate the potential of skin allergy reaction to mucoadhesive film containing Acmella oleracea extract by patch skin test at 2nd day after test	Evaluate at 2 days after patch skin test application	Outcome will be a number of participants with skin allergic reaction assessed by patch skin test at 2nd day after test
To study adverse effect related to mucoadhesive film use	Evaluate within 2 hours after mucoadhesive film application	Outcome will be a number of participants who have adverse effect and the symptom of adverse effect
To study the duration of mucosal adhesion of mucoadhesive film in healthy oral mucosa	Self reporting the time at which the film detaches (e.g. 16.30 hr.), within 24 hours after mucoadhesive film application	Outcomes will be the duration in minutes of the mucoadhesive film adhering to participant' s oral mucosa
To investigate the potential of skin allergy reaction to mucoadhesive film containing Acmella oleracea extract by skin prick test	Evaluate at 15 minutes after test in the 1st visit	Outcome will be a number of participants with skin allergic reaction assessed by skin prick test
To investigate the potential of skin allergy reaction to mucoadhesive film containing Acmella oleracea extract by patch skin test at 7th day after test	Evaluate at 7th day after patch skin test application	Outcome will be a number of participants with skin allergic reaction assessed by path skin test at 7th day after test.
To study the local anesthetic effect	Self reporting at 1st visit, at 3 and 5minutes after application	Outcome will be a score of Numeric rating scale (NRS) of local anesthetic effect. On a scale of 0-10, where 0 = no anesthetic effect and 10 = completely anesthetize
