ABSTRACT
AIM/BACKGROUND:
The combination of drugs with different mechanisms of action could be more effective due to an enhanced synergistic activity. The pharmacological interactions between rutin and paracetamol, and rutin and non-steroidal anti-inflammatory drugs (NSAIDs), such as naproxen, ketorolac, and diclofenac were investigated using in vitro and in vivo assays.METHODS:
Individual and drug combination response curves of rutin-NSAIDs, and rutin-paracetamol (each at 0.001-0.1 mmol for in vitro studies and ranging from 1.25-100 mg/kg p.o. for in vivo studies) were evaluated in RAW 264.7 macrophages [inhibition of nitric oxide (NO) using the Griess reagent] and Balb/c mice (acetic acid-induced writhing test). An isobolographic analysis was used to assess the type of interaction between rutin and NSAIDs and rutin-paracetamol in a proportion of 11.RESULTS:
Rutin alone and in combination with paracetamol and NSAIDs decreased NO production and the number of writhings in a concentration/dose-dependent manner. The isobolograms showed that all in vitro combinations of rutin-NSAIDs and rutin-paracetamol exerted synergistic effects. The combination rutin-diclofenac showed an interaction index of 0.17. In the in vivo assay, the combinations of rutin-diclofenac (interaction indexâ¯=â¯0.195) and rutin-ketorolac (interaction indexâ¯=â¯0.408) displayed synergistic effects, and the combination rutin-paracetamol exhibited additive effects.CONCLUSION:
Rutin produces synergistic effects with paracetamol and NSAIDs in in vitro and in vivo assays.Palabras clave
