ABSTRACT

Objetivo: Determinar las posibles interacciones farmacológicas de las hojas de Maytenus macrocarpa, con fármacos estimulantes e inhibitorios de la motilidad intestinal. Métodos: Se utilizaron 110 ratones albinos machos, con pesos medios de 25 g, se empleó el método de Arbos y col, se administró carbón activado al 5


vía oral, dosis de 0.1ml/10g, como marcador intestinal. Los grupos experimentales fueron: control (agua destilada 0,3ml), hojas de chuchuhuasi 1 (500mg/kg), hojas de chuchuhuasi 2 (3000mg/kg), atropina (1,5mg/kg), loperamida (5mg/kg), neostigmina (0,4mg/kg), metoclopramida (10mg/kg), hojas de chuchuhuasi 1 con metoclopramida, hojas de chuchuhuasi 1 con loperamida, hojas de chuchuhuasi 2 con metoclopramida y hojas de chuchuhuasi 2 con loperamida. Para la validación estadística se usó la prueba de Wilconxon, ANOVA y Tukey. Resultados: El porcentaje de recorrido intestinal de carbón activado fue de 27,04, 34,15, 31,66, 25,57, 15,89, 43,30, 33,99, 32,40, 27,90, 49,34 y 25,36 respectivamente, el test de ANOVA de dos colas revelo una p=0,0007. El test de Tukey indico p<0.05 versus el control para neostigmina, loperamida y la interacción chuchuhuasi 3000 mg/kg con metoclopramida, en este último, el test de Wilconxon presento un valor p<0,05. Conclusiones: Se observó interacciones farmacológicas de antagonismo sobre la motilidad intestinal, entre chuchuhuasi y Loperamida y sinergismo entre chuchuhuasi y metoclopramida.


Objectives: To determine the possible pharmacological interactions from the leaves of Maytenus macrocarpa with inhibitory and stimulating bowel motility drugs. Methods: We used 110 male albino mice with average weight of 25g, Arbos and others method was applied. Activated charcoal was administered at 5


at dose of 0.1ml/10g, as an intestinal marker. The experimental groups included 0.1 ml/10 g of distilled water, leave extract of M. macrocarpa 1 (500mg/kg), leave extract of M. macrocarpa 2 (3000 mg/kg), 1,5mg/kg of atropine, 5mg/kg of loperamide, 0.4mg/kg of neostigmine, 10mg/kg of metoclopramide, leave extract of M. macrocarpa 1 with metoclopramide, leave extract of M. macrocarpa 1 with loperamide, leave extract of M. macrocarpa 2 with metoclopramide and leave extract of M. macrocarpa 2 with loperamide. The statistical validation was based on Wilconxon, ANOVA and Tukey test. Results: The intestinal charcoal run percentage was 27.04, 34.15, 31.66, 25.57, 15.89, 43.30, 33.99, 32.40, 27.9, 49.34 and 25.36 respectively. The ANOVA test result in p= 0.0007. The Tukey test indicated p <0.05 versus the control group for neostigmine, loperamide, and the interaction between leave extract of M. macrocarpa 2 with metoclopramide, for the last the Wilcoxon test result in p <0.05. Conclusions: It was observed antagonism drug interactions on gastrointestinal motility between leaves extract of M. macrocarpa with loperamide and synergism interactions with metoclopramide.
