The treatment and management of tuberculosis using conventional drug delivery systems remain challenging due to the setbacks involved. The lengthy and costly treatment regime and patients' non-compliance have led to drug-resistant tuberculosis, which is more difficult to treat. Also, anti-tubercular drugs currently used are poor water-soluble drugs with low bioavailability and poor therapeutic efficiency except at higher doses which causes drug-related toxicity. Novel drug delivery carrier systems such as mesoporous silica nanoparticles (MSNs) have been identified as nanomedicines capable of addressing the challenges mentioned due to their biocompatibility. The review discusses the sol-gel synthesis and chemistry of MSNs as porous drug nanocarriers, surface functionalization techniques and the influence of their physico-chemical properties on drug solubility, loading and release kinetics. It outlines the physico-chemical characteristics of MSNs encapsulated with anti-tubercular drugs.
由于存在诸多挫折,使用传统给药系统治疗和管理结核病仍然具有挑战性。漫长且昂贵的治疗方案以及患者的不依从性导致了耐药结核病,而耐药结核病更难治疗。此外,目前使用的抗结核药物是水溶性差的药物,生物利用度低,治疗效率差,除非使用更高剂量,但这会导致药物相关毒性。新型药物递送载体系统,如介孔二氧化硅纳米颗粒(MSNs),因其生物相容性而被视为能够应对上述挑战的纳米药物。本文综述讨论了作为多孔药物纳米载体的MSNs的溶胶-凝胶合成及化学性质、表面功能化技术以及它们的物理化学性质对药物溶解度、载药量和释放动力学的影响。文中概述了包裹抗结核药物的MSNs的物理化学特性。
