Dessa forma, os resultados evidenciaram uma possível ação do enxaguatório contendo Chamomilla recutita na redução da incidência da mucosite, na dose de 1%, em pacientes submetidos ao TCTH, bem como uma menor intensidade de mucosite graus II e III nos grupos que receberam as doses de 1 e 2%. Contudo, para confirmar estes achados faz-se necessário ampliar a amostra deste estudo empregando o método aqui desenvolvido. O enxaguatório bucal de Chamomilla recutita nas dosagens de 0,5; 1 e 2% foi bem tolerado pelos pacientes e demonstrou ser seguro, uma vez que nenhum efeito adverso moderado ou severo foi identificado. Oral mucositis (OM) is an inflammatory complication frequently manifested by patients undergoing Hematopoietic Stem Cell Transplantation (HSCT), as a result of aggressive treatment regimen employed. However, prevention and treatment are still controversial in literature. Chamomile has been used for therapeutic purposes for centuries and has been employed in some HSCT services for both prevention and treatment of OM. However, no studies that investigate its action in this clientele have been identified. Thus, this study aimed to compare the incidence, intensity and duration of oral mucositis in adult patients undergoing HSCT according to the doses (0.5; 1 or 2%) of Chamomilla recutita in mouthwash. The study was carried out in four stages. First an integrative literature review was conducted, in order to identify the scientific evidence available regarding the use of Chamomilla recutita to reduce the occurrence and intensity of inflammatory processes. It was evidenced that Chamomilla recutita is likely to have topic anti-inflammatory action, for several inflammatory disorders. Considering the results of this review and those obtained with studies in vitro and in animals, it was deemed appropriate to develop the clinical study. At the second stage, the plant drug was selected, physical-chemical and microbiological analysis were carried out and quantification of apigenin-7-glucoside was determined. Tests identified the excellent quality of capitula from the selected sample. In sequence, at the third phase, the fluid extract was obtained, whose analysis showed the maintenance of quality and content of active principle. Subsequently, the extract was successfully incorporated in three formulations of mouthwash, according to the dosages proposed for the clinical study (0.5; 1 and 2%). At last, a clinical study with 23 patients who underwent allogeneic HSCT was performed, randomized into four groups. Regarding the incidence of mucositis, 5 (83.3%) patients in group B who received the mouthwash with ...
