Rehmanniae Radix Preparata (RRP) has been used to management of osteoporotic pain in traditional Chinese medicine trials. However, how RRP exhibits the anti-nociceptive effect remains largely unknown. To this end, estrogen-deficient rats were orally gavaged with aqueous RRP extracts for 12 weeks. The tail flick latency, Von-Frey and formalin assays were employed to evaluate pain sensitization. The administration of RRP alleviates allodynia and hyperalgesia in estrogen-deficient rats. These alterations were associated with a decrease in the expression of substance P (SP), neurokinin-1 receptor (NK-1R), phospho (p)-PI3K, p-protein kinase B (Akt), and transient receptor potential cation channel subfamily V member 1 (TRPV1) in the spinal cord. In addition, RRP improves bone quality in the rats. These results suggest RRP could attenuate pain sensitization and improve bone quality through regulation of PI3K/Akt/TRPV1 signaling pathway during menopause stages. And RRP is considered a novel source of anti-osteoporotic pain drug candidates. |
