Rebamipide gargle and benzydamine gargle in prevention and management of chemo-radiotherapy and radiotherapy-induced oral mucositis in head and neck cancer patients (randomized clinical trial). BMC Oral Health 2024; 24:645. [PMID: 38824583 PMCID: PMC11143556 DOI: 10.1186/s12903-024-04379-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2023] [Accepted: 05/16/2024] [Indexed: 06/03/2024] Open
Abstract
OBJECTIVES This study aimed to evaluate the preventive and therapeutic effects of rebamipide gargle in comparison with benzydamine in head and neck cancer patients undergoing radiotherapy with or without chemotherapy. MATERIALS AND METHODS Phase III randomized clinical trial was conducted from January 2021 till August 2022 on one hundred patients with head and neck cancer receiving high doses of radiotherapy. These patients were equally allocated into either rebamipide group or benzydamine group, The measured outcomes were the incidence of oral mucositis ≥ grade1, according to the WHO mucositis scale, in addition to the duration, and the onset of oral mucositis. RESULTS There was no statistically significant difference between the two groups, regarding the incidence of a severe grade of oral mucositis (WHO grades 3), as well as the onset and duration of oral mucositis. Both gargles succeeded to prevent the development of WHO grade 4 oral mucositis. Side effects reported were mainly burning sensation in benzydamine group and nausea in rebamipide group. CONCLUSION Rebamipide mouthwash was as beneficial as benzydamine mouthwash in minimizing the incidence of severe oral mucositis induced by treatment of head and neck cancer. However, rebamipide gargle proved to be superior to benzydamine in terms of reduction in the severity of the radiation-induced oral mucositis. TRIAL REGISTRATION The trial was registered in the protocol Registration and Result system of Clinical Trials (Registration ID: NCT04685395)0.28-12-2020.

Abstract
Ophthalmic delivery of luteolin (LU) was studied after formulating a carrageenan-based novel ion-sensitive in situ gel (ISG) incorporating oleophytocubosomes for prolonged ocular residence time and improved ocular bioavailability of the poorly absorbed herbal drug luteolin. The prepared oleophytocubosomes and ISG were compared with LU suspension. Optimized oleophytocubosomes possessed small, homogenously distributed negatively charged particles with high entrapment efficiency. Polarized light microscope revealed a cubic phase. Optimized ISG matrix composed of 0.4% kappa carrageenan (KC), and 2% hydroxypropylmethylcellulose (HPMC) demonstrated rapid gelation, high resistance to dilution, increased viscosity after gelation, and strong mucoadhesive properties. oleophytocubosomes exerted improved drug release, while a more sustained release was observed for ISG oleophytocubosomes. The antioxidant activity of both formulations was significantly higher than that of LU suspension. Oleophytocubosome and ISG oleophytocubosome revealed significantly higher apparent permeability coefficients of 3.62 and 2.90 folds, respectively, compared to LU suspension. Irritation tests showed the safety of both formulations for single- and multiple-ocular administration. In-vivo studies demonstrated that the ISG system showed prolonged antiglaucoma effects and a faster anti-inflammatory effect, followed by oleophytocubosomes.

Abstract
Oral mucositis and esophagitis represent the most frequent and clinically significant complications of cytoreductive chemotherapy and radiotherapy, which severely compromise the patient quality of life. The local application of polymeric gels could protect the injured tissues, alleviating the most painful symptoms. The present work aims at developing in situ gelling formulations for the treatment of oral mucositis and esophagitis. To reach these targets, κ-carrageenan (κ-CG) was selected as a polymer having wound healing properties and able to gelify in the presence of saliva ions, while hydroxypropyl cellulose (HPC) was used to improve the mucoadhesive properties of the formulations. CaCl₂ was identified as a salt able to enhance the interaction between κ-CG and saliva ions. Different salt and polymer concentrations were investigated in order to obtain a formulation having the following features: (i) low viscosity at room temperature to facilitate administration, (ii) marked elastic properties at 37 °C, functional to a protective action towards damaged tissues, and (iii) mucoadhesive properties. Prototypes characterized by different κ-CG, HPC, and CaCl₂ concentrations were subjected to a thorough rheological characterization and to in vitro mucoadhesion and washability tests. The overall results pointed out the ability of the developed formulations to produce a gel able to interact with saliva ions and to adhere to the biological substrates.

Abstract
Anticancer drug-induced stomatitis develops in 30% to 40% of cancer cases that undergo chemotherapy. However, medications for this condition are not commercially available in Japan. Upon obtaining approval of the ethics committee, a mouthwash containing rebamipide as the active ingredient (rebamipide mouthwash) was administered to one inpatient and four outpatients, who had developed stomatitis caused by cancer chemotherapy. Starting from 14 d after the administration of the rebamipide mouthwash, the patients scored a stomatitis survey on oral state, pain level, and diet and recorded the number of times they gargled, as well as any stomatitis observations, in a stomatitis diary. The total scores for the points for each of the three types of survey sections were classified into Grades 0 to 4 and evaluated as a stomatitis evaluation score (SES). The SES became "0" in three out of the five patients within 14 d of treatment. No change in SES was found in one patient. In the remaining patients, SES became "0" once but increased again later. Using image analysis software (ImageJ), the area at which the stomatitis was observed was measured. When comparing SES and change in the area in patients who agreed to participate, gradual reductions in the extent of stomatitis was observed even during the period when SES did not change. Having patients fill in an observation chart was effective for grasping changes in symptoms in outpatients.

Abstract
In the present study, all-trans retinoic acid (RA) gels formulated with various compositions of polyethylene oxide (Emulgen®) and iota-carrageenan (ι-CG) were prepared and their physicochemical properties were evaluated. The compression energy, which is the work required to compress the product through a fixed distance, increased with increasing amount of ι-CG or Emulgen®. The adhesion energy and displacement decreased with increasing amount of ι-CG or Emulgen® due to the progression of gel formation. From the results of the sensory tests, the properties of RA gels such as adhesiveness, gel strength and spreadability seemed to be adjustable depending on the condition of skin by varying the components of RA gels. Through photostability study, the expiration date and storage conditions of RA gels were determined as "4°C for 28 d with no exposure to light."

Abstract
Objectives To assess the efficacy and safety of rebamipide in preventing
chemoradiotherapy-induced oral mucositis in patients with oral cancer. Material and Methods Patients with oral cancer treated with chemoradiotherapy (daily radiotherapy
plus docetaxel hydrate once a week) were enrolled for this study. They were
assigned in a double-blind fashion to receive either rebamipide gargle or
placebo on the days of chemoradiotherapy. Oral mucositis was assessed using
the WHO grading system. The primary endpoint of this study was the incidence
of grade 3 - 4 mucositis after exposure to 40 Gy radiation (4 weeks). The
secondary endpoint was the effect of rebamipide gargle on tumour response to
chemoradiotherapy. Results Twenty-four patients were randomly assigned to receive rebamipide gargle (n =
12) or placebo-gargle (n = 12) during chemoradiotherapy. The number of
patients with severe mucositis (WHO ≥ 3) was higher in the placebo group
than in the rebamipide group (83.3% vs. 33.3%, P = 0.036). In addition, no
effect of rebamipide gargle on tumour response to chemoradiotherapy was
recognized compared with the placebo group. Conclusions For patients with oral cancer undergoing chemoradiotherapy, rebamipide gargle
may contribute to decrease the severity of oral mucositis.
