Synergism between Naproxen and Rutin in a Mouse Model of Visceral Pain

ABSTRACT The aim of the present study was to evaluate the antinociceptive interaction between naproxen and the glycoside flavonoid, rutin in the acetic acid‐induced writhing test in mice. Naproxen (5, 20, 50, and 100 mg/kg p.o.) or rutin (10, 25, 50, and 100mg/kg p.o.) were administered 60 min before the intraperitoneal administration with acetic acid. The dose‐response curve of each individual compound and the experimental effective dose 50 (ED50) value were obtained to determinate different proportions of the combinations between the two compounds (naproxen‐rutin 1:1, 3:1, and 3:1) in the writhing test. The results indicated a synergistic antinociceptive interaction between two drugs with different mechanism of action, naproxen and rutin in all the combinations.Drug Dev Res, 2017. © 2017 Wiley Periodicals, Inc.
