Abstract

Cannabidiol (CBD) has received great scientific interest due to its numerous therapeutic applications. Degradation in the gastrointestinal (GI) tract, first-pass metabolism, and low water solubility restrain bioavailability of CBD to only 6% in current oral administration. Lipid-based nanocarriers are delivery systems that may enhance accessibility and solubility of hydrophobic payloads, such as CBD. Conventional lecithin-derived liposomes, however, have limitations regarding stability in the GI tract and long-term storage. Ether lipid-based archaeosomes may have the potential to overcome these problems due to chemical and structural uniqueness. In this study, we compared lecithin-derived liposomes with archaeosomes in their applicability as an oral delivery system of CBD. We evaluated drug load, storage stability, stability in a simulated GI tract, and in vitro particle uptake in Caco-2 cells. Loading capacity was 6-fold higher in archaeosomes than conventional liposomes while providing a stable formulation over six months after lyophilization. In a simulated GI tract, CBD recovery in archaeosomes was 57 ± 3% compared to only 34 ± 1% in conventional liposomes and particle uptake in Caco-2 cells was enhanced up to 6-fold. Our results demonstrate that archaeosomes present an interesting solution to tackle current issues of oral CBD formulations due to improved stability and endocytosis.

摘要

由于其众多的治疗应用,大麻二酚 (CBD) 引起了极大的科学兴趣。在胃肠道 (GI) 中降解、首过代谢和低水溶性将 CBD 的生物利用度限制在当前口服给药的 6%。基于脂质的纳米载体是一种可能提高疏水性有效载荷(如 CBD)的可及性和溶解度的递送系统。然而,常规的卵磷脂衍生脂质体在 GI 道中的稳定性和长期储存方面存在局限性。基于醚脂质的类病毒体由于其化学和结构的独特性,可能具有克服这些问题的潜力。在这项研究中,我们比较了卵磷脂衍生的脂质体与类病毒体作为 CBD 口服递送系统的适用性。我们评估了药物负载、储存稳定性、在模拟胃肠道中的稳定性以及在 Caco-2 细胞中的体外颗粒摄取。与传统脂质体相比,类病毒体的载药量高 6 倍,在冻干后 6 个月内仍提供稳定的配方。在模拟胃肠道中,与传统脂质体相比,类病毒体中 CBD 的回收率为 57±3%,而只有 34±1%,并且 Caco-2 细胞中的颗粒摄取增加了 6 倍。我们的结果表明,由于稳定性和内吞作用的提高,类病毒体为解决当前 CBD 口服制剂的问题提供了一个有趣的解决方案。
