Abstract
This paper contains data that can be used in interpretation of the pharmacological effects of sinomenine combined with gabapentin or ligustrazine hydrochloride on chronic pain. The data can be divided into two parts. The first part is regarding if there were noticeable side effects accompanying drug applications of sinomenine plus gabapentin or ligustrazine hydrochloride. These side effects include sedation and change of core body temperature as well as tissue edema and sustained itch. The data were acquired from the open field test in mice, and provided insights for the effects of drug combination therapy on locomotive activities, rearing behaviors and body temperature. The second part is regarding whether sinomenine could be accumulated in the central nervous system (CNS) tissue following repeated drug administration. The data were acquired using microdialysis, which illustrated the pharmacokinetic properties of sinomenine, by showing relative concentrations of sinomenine in blood and CNS tissue, following single or repeated drug application. Data presented here is related to and supportive of the research article by Gao et al., "Sinomenine facilitates the efficacy of gabapentin or ligustrazine hydrochloride in animal models of neuropathic pain"[1], where interpretation of the research data presented here is available.
