Abstract
Niclosamide 早期主要用於治療寄生蟲感染疾病,然而最近研究發現此藥物除了用於寄生蟲的醫療用途之外尚有許多臨床應用,包括癌症、細菌及病毒感染 (COVID-19)、第二型糖尿病等代謝疾病,此藥物具多重藥理活性可被開發為一種新型態治療方法。Niclosamide 屬於 BCS class II 藥物,由於其溶解度低且生體可用率低於10 %,因此本研究希望透過開發自微乳化藥物傳遞系統 (Self-microemulsifying Drug Delivery System, SMEDDS) 和使用噴霧乾燥技術製備固態SMEDDS (s-SMEDDS) 來提高液態SMEDDS (l-SMEDDS) 的穩定性,從而改善該藥物的溶解度並增加其生物利用度。
l-SMEDDS 具有約16 nm的粒徑大小,最終製劑的載藥量為10 mg/mL。並使用親水性載體葡聚醣和疏水性載體矽酸鈣用於製備 s-SMEDDS 評估它們對噴霧乾燥過程的影響。示差掃描量熱儀和 X-ray 廣角繞射研究表明,在 l-SMEDDS 和 s-SMEDDS 製劑中,藥物結晶都變成了無定形形式。在體外溶離研究中, l-SMEDDS 和 s-SMEDDS 可以在30分鐘內釋放超過80 %的藥物。在安定性研究中也表明藥物含量在3個月內保持在約90 %以上。在細胞毒性試驗中, l-SMEDDS在24小時和48小時的細胞存活率為85 %,適用於 Caco-2 細胞,可認為是安全的材料。在藥物動力學研究中, l-SMEDDS 組的血中最高濃度(Cmax) 明顯高於游離藥物,相對生體可用率增加2.3倍,s-SMEDDS 組分別增加1.5 ~ 1.7倍。
綜合以上結果,l-SMEDDS 和 s-SMEDDS 製劑皆成功製備,兩者都表現出
出色的安定性和藥物釋放特性,同時有效提升生體可用率。
