摘要

塞来昔布是一种选择性 COX-2 抑制剂非甾体抗炎药(NSAID),具有与黑胡椒次生代谢产物胡椒碱相似的镇痛和抗炎特性。本研究旨在制备塞来昔布和胡椒碱的共晶体,以提高塞来昔布的溶解速率和可压缩性。该共晶体采用播种法合成,并利用粉末 X 射线衍射 (XRD)、差示扫描量热 (DSC)、红外分光光度法和单晶 X 射线衍射技术对其进行了全面表征。PXRD 的完全变化、DSC 测量中熔点的降低以及傅立叶变换红外光谱中 N-H 伸展带的移动都表明共晶相的形成。单晶 XRD 证实塞来昔布和哌啶形成了等摩尔比的共晶体。为确认共晶体对溶解的影响,进行了本征溶解试验,结果表明与完整的塞来昔布相比,共晶体的溶解度略有增加。为了评估其物理机械性能,我们用不同的力将共晶体粉末压制成片剂。结果表明,与完整的塞来昔布相比,由于共晶体晶格中存在滑移面,其可压缩性得到了显著改善。总之,与完整的塞来昔布相比,我们的新型塞来昔布-哌啶共晶体表现出独特的理化特性,溶出率和可压缩性均有所提高。

A novel cocrystal approach celecoxib with piperine: Simultaneously enhance dissolution rate and compressibility.

Celecoxib, a selective COX-2 inhibitor non-steroidal anti-inflammatory drug (NSAID), exhibits analgesic and anti-inflammatory properties similar to piperine, the secondary metabolite of Piper nigrum L. Unfortunately, celecoxib has a low compressibility and low dissolution rate in aqueous medium. This study aimed to prepare a cocrystal of celecoxib and piperine to enhance the dissolution rate and compressibility properties of celecoxib. The cocrystal was synthesized using the seeding method and thoroughly characterized using Powder X-ray diffraction (XRD), differential scanning calorimetry (DSC), infrared spectrophotometry, and single-crystal X-ray diffraction techniques. The complete change in PXRD, decrease in melting point in DSC measurements, and shift in the NH stretching band in the FT-IR spectrum suggested the formation of cocrystals phase. Single-crystal XRD confirmed the formation of an equimolar ratio of cocrystals of celecoxib and piperine. The intrinsic dissolution test was conducted to confirm the impact on the cocrystal to dissolution, and it showed a slight increase compared to intact celecoxib. To assess the physico-mechanical properties, the cocrystal powders were compressed into tablets with varying forces. The results demonstrated a significant improvement in compressibility compared with intact celecoxib owing to the slip plane in the crystal lattice of the cocrystal. In conclusion, our novel celecoxib-piperine cocrystal exhibited distinct physicochemical characteristics compared to intact celecoxib, showing enhanced dissolution rate and compressibility.
