简要总结
Recurrent Aphthous Stomatitis (RAS) is experienced by almost everyone and appears suddenly. Even though the risk of death due to the condition is small, its presence can make a person feel uncomfortable eating, drinking, and talking so there will be a decrease in the quality of a person's life in their daily lives. Recently, α-Mangostin (α-M) from mangosteen rind (Garcinia mangostana L) has been shown its effect to reduce oral mucosal sores on RAS in preclinical studies in rats. Therefore, research is needed to prove the benefits (efficacy) and safety of therapy in the form of a hydrogel film patch/plaster film with a chitosan alginate base as a carrier for α-Mangostin for the treatment of RAS patients.
详细描述
Topical medications are the primary option for addressing RAS (Recurrent Aphthous Stomatitis) due to their affordability, effectiveness, and safety. These treatments encompass various forms such as mouthwashes, aerosols, lozenges, and ointments, available in liquid, solid, and semi-solid preparations. However, employing topical drugs faces challenges related to achieving desired therapeutic outcomes. A significant hurdle is the hindered delivery of drugs to the oral mucosa, often referred to as "saliva wash out," which leads to the removal and rinsing away of the drug from the mucosal surface.
Efforts in developing drug delivery systems for RAS treatment are directed towards achieving several goals. These include prolonging the time drugs remain effective at the site of the ulcer, ensuring the release of adequate drug concentrations to the ulcer, and alleviating pain. Addressing this issue involves the creation of film formulations that can serve as a protective layer for the ulcer. Such formulations act as barriers against external stimuli while offering a certain degree of pain relief.
An indigenous plant of Indonesia that has found application in traditional healing is the mangostin peel (Garcinia mangostana L.). α-mangostin, extracted from the rind of the mangosteen, has been employed in traditional medicine. Among its attributes, α-mangostin exhibits anti-inflammatory properties, functioning effectively by impeding the inflammatory response. This characteristic positions α-mangostin as a viable alternative compound for addressing RAS management. To facilitate the delivery of α-mangostin, a combination of two mucoadhesive polymers, specifically sodium alginate and chitosan, is utilized as a drug delivery system.
In earlier studies, the development and analysis of a hydrogel film containing α-mangostin, utilizing a chitosan-alginate foundation, were conducted to explore their potential for treating RAS in vivo. These experiments involved testing on white Wistar rats, resulting in a remarkable 93% healing rate by the seventh day. Consequently, additional research focusing on the chitosan-alginate based α-mangostin hydrogel film will progress to clinical and safety trials. The objective is to establish its effectiveness among RAS patients and assess its suitability as a readily applicable treatment option.

研究组 & 干预措施
α-Mangostin Hydrogel Film With Chitosan Alginate Base
Subjects will receive α-Mangostin Hydrogel Film With Chitosan Alginate Base in the form of a patch. Subjects will apply the patch once a day after breakfast or at night before sleep, subjects will be told to avoid drinking or eating for 1 hour after using the hydrogel film because these activities can remove the hydrogel film. Ulcer size and VAS score will recorded on the first day (baseline), the 3rd day, the 5th day, and the 7th day
干预措施: α-Mangostin Hydrogel Film With Chitosan Alginate Base (Drug)
Placebo
Subjects will receive Hydrogel Film With Chitosan Alginate Base without an active compound in the form of a patch. Subjects will apply the patch once a day after breakfast or at night before sleep and will be told to avoid drinking or eating for 1 hour after using the hydrogel film because these activities can remove the hydrogel film. Ulcer size and VAS score will recorded on the first day (baseline), the 3rd day, the 5th day, and the 7th day
干预措施: Placebo (Drug)
结局指标
主要结局
Pain Visual Analogue Scale (VAS Score)
时间窗: 7 days
Determine the effect of α-Mangostin for reducing pain intensity. The Visual Analogue Scale (VAS) measures pain intensity. The VAS consists of a 10cm line, with two end points representing 0 (no pain) and 10 (the worst pain ever felt / imagined by the subject). After being explained, subjects will be asked to place a mark on the line to rate their current level of pain. The investigators will measure the distance of the mark from 0 end point using a ruler and record the number up to 1 decimal point. VAS scores will be measured and recorded twice, i.e. day 1 and day 7.
Ulcer Size
时间窗: 7 days
The diameter of the ulcer will be measured twice (day 1 and day 7) using a ruler.
