Drimys é um dos gêneros mais conhecidos da família botânica Winteraceae. As espécies que compõe este gênero têm sido amplamente utilizadas na medicina popular latino americana para o tratamento de malária, dores gástricas, dor de dente, anemia, entre outros. Além do mais, em algumas localidades, as folhas secas e as bagas dos frutos são utilizadas na culinária como condimento pois possuem sabor apimentado. O objetivo deste trabalho foi realizar uma revisão sistemática sobre a fitoquímica, atividades biológicas, farmacológicas e toxicologicas das espécies do gênero Drimys. Para isso, foram realizadas buscas em diferentes plataformas, no período de 1987 e 2022, utilizando-se a palavra "Drimys", indicativa do gênero botânico, acompanhado dos descritores: "Winteraceae", "pharmacology", "neoplasm", "inflammation", "insecticides", "clinical trial", "pain", "food", "ulcer", "malaria" e "toxicity". Incluiu-se trabalhos sobre o perfil fitoquímico, atividades biológicas e potencial farmacológico. Foram selecionados 77 artigos científicos sobre as espécies D. winteri, D. brasiliensis, D. angustifolia, D. granadensis e D. piperita com informações de estudos in vivo e in vitro que possibilitam o conhecimento medicinal, a conservação e o uso sustentável destas espécies.

Drimys is one of the best known genera of the botanical family Winteraceae. The species that make up this genus have been widely used in Latin American popular medicine for the treatment of malaria, gastric pain, toothache, anemia, among others. Moreover, in some places, the dried leaves and berries of the fruits are used in cooking as a condiment because they have a spicy flavor. The objective of this work was to perform a systematic review on the phytochemical, biological, pharmacological and toxicological activities of the species of the genus Drimys. For this, searches were made in different platforms, between 1987 and 2022, using the word "Drimys", indicative of the botanical genus, accompanied by the descriptors: "Winteraceae", "pharmacology", "neoplasm", "inflammation", "insecticides", "clinical trial", "pain", "food", "ulcer", "malaria" and "toxicity". Papers on phytochemical profile, biological activities, and pharmacological potential were included. A total of 77 scientific articles on the species D. winteri, D. brasiliensis, D. angustifolia, D. granadensis and D. piperita were selected, with information from in vivo and in vitro studies that enable medicinal knowledge, conservation and sustainable use of these species.

Stress ulcer survey of anti-ulcerative drug use in patients undergoing arthroscopic operation / 实用医学杂志

Objective To investigate anti-ulcerative drug use in patients undergoing arthroscopic operation against stress ulcer. Methosds A total of 297 patients undergoing arthroscopic operation during Jan. to Aug. 2013 in our hospital were recruited and retrospectively analyzed with Excellspreadsheet. Results Among 297 patients in the study, ninety-four patients (31.6%) used AUD before operation, most (94.9%) administered by intravenous, and drug utilization index was 1.35. Ninety-eight point nine patients used proton pump inhibitors (PPIs) in which Lansoprazole was prescribed most. Conclusion This study highlights the overuse of PPIs in patients undergoing arthroscopic operation.

Validación preclínica de extractos fluidos de Croton argenteus L. / Preclinical validation of fluid extracts from Croton argenteus L.

Croton argenteus L. no es conocida como planta medicinal tradicional en Cuba; pertenece al mismo género de C. lechleri, de cuyo tronco se obtiene la sangre de grado o drago en los países amazónicos que tiene diversos usos etnomédicos para tratar problemas de salud como: diarrea, heridas, úlceras gastroduodenales, inflamaciones, dolor, picaduras de insectos e infecciones virales. Existen estudios sobre esta especie, sin embargo, no se encontraron publicaciones sobre esta planta que crece en Cuba. El objetivo fue validar, en extractos de C. argenteus, efectos reportados para la planta amazónica. Se prepararon 2 extractos fluidos de partes aéreas, sin tallos, secas con etanol al 30 y 80% y se realizaron estudios de: tamizaje fitoquímico, analgesia en contorsiones provocadas por ácido acético intraperitoneal y tránsito intestinal con carbón activado por vía oral en ratones; antiinflamatorio en granuloma inducido por algodón, lesiones gástricas inducidas por indometacina y toxicidad aguda oral con el modelo de clases tóxicas agudas en ratas. Las dosis administradas de ambos extractos fueron 500 y 1000 mg de material vegetal seco/kg p.o.). Los resultados no demostraron ninguno de los efectos farmacológicos estudiados. El extracto fluido 30% no resultó tóxico, pero el preparado con etanol al 80% clasificó como muy tóxico. Los extractos fluidos de partes aéreas sin tallos de C. argenteus carecieron de actividad para las acciones farmacológicas evaluadas.

In Cuba , Croton argenteus L. is not known as traditional medicinal plant. It belongs to the same genus that C. lechleri , from whose trunk sangre de drago is obtained in the Amazonian countries. It has diverse ethnomedical uses to treat health problems, such as diarrhea, wounds, gastroduodenal ulcers, inflammations, pain, insect bites, and viral infections. There are studies on this species; however, no publications have been found on this plant growing in Cuba . The objective was to validate, in extracts from C. argenteus , the effects reported for the Amazonian plant. Two fluid extracts were prepared from aerial parts, without stalks, dried with ethanol 30 % and 80 %. Studies of phytochemical screening, analgesia in contortions caused by intraperitoneal acetic acid, and bowel transit with oral activated carbon were conducted in mice. The antiinflammatory effect was studied in the case of cotton-induced granuloma, indomethacin-induced gastric injury, and oral acute toxicity with the model of acute toxic lesions in rats. The administered oral doses of both extracts were 500 and 1000 mg of dry plant material /kg. According to the results, the expected pharmacological effects were not proved. The fluid extract (30 %) wasn't toxic, but preparation using ethanol 80% was. Fluids extracts of aerial parts without stalks of C. argenteus lacked activity for the evaluated pharmacological actions.

Drug Utilization Review of Antiulcerative Agents in Korean Elderly Inpatients / 예방의학회지

OBJECTIVES: To review the drug prescription pattern of antiulcerative agents for elderly inpatients. METHODS: The study population comprised inpatients of community hospitals who were members of the Korean Elderly Pharmacoepidemiologic Cohort (KEPEC), aged 65 years or over, beneficiaries of the Korea Medical Insurance Corporation (KMIC) and residing in Busan city in 1993. The drug prescription information was collected from the claims data of hospitals where the cohort members received medical care between January 1993 and December 1994. The information included personal identification, age, gender, diagnosis, drug dosage, date of hospital admission and name of medical institutions where the study subjects received drug prescriptions. The data analysis produced outcomes in terms of distribution of antiulcerative agents by class and by medical institution and trend of relative prescription. Analysis was also performed in terms of combined prescriptions of antiulceratives and drugs that could induce risk from drug interaction with antiulceratives. RESULTS: The number of patients prescribed antiulcerative agents was 1,059 (64.9%) male and 1,724 (65.5%) female among the total inpatients. An antacid and composite agent was the most frequently prescribed antiulcerative agent (70.8%), followed by H2 antagonist (16.0%). Among the potential drugs that could induce risk from drug interaction with the antiulcerative agents, diazepam was the most frequently prescribed. The proportion of diazepam co-prescription was 22.5% of the total cimetidine prescriptions and 14.5% of the total omeprazole prescriptions. CONCLUSIONS: Antiulcerative drugs were frequently prescribed in the elderly inpatients. The adverse drug reaction could possibly be due to drug interaction. The study results could be used as fundamental data for further drug utilization review of antiulcerative agents.
