概括

微晶制剂显著改善了眼部药物输送,用于像塔克罗利斯 (tacrolimus) 这样的不溶性药物. 这种新的方法提高了溶解度,并使持续释放眼滴能够改善患者的治疗结果.

科学领域:

眼科医生眼科眼科
材料科学材料科学材料科学
制药科学制药科学

背景情况:

提高药物溶解度对于有效的眼部药物输送至关重要,特别是对于不容易溶解的化合物.
微结晶和表面修饰技术为增强眼滴药物吸收提供了潜在的解决方案.

研究的目的:

合成德克萨米他微晶 (DES MCs) 和塔克罗利斯微晶 (TAM MCs).
为了增强这些微晶的眼睛保留和持续释放特性,使用聚乙烯胺 (PEI) 和氨酸 (HA) 的层次自我组装.
评估开发的用于眼部药物输送的微晶配方的疗效和安全性.

主要方法:

使用药物结晶技术来制备DES MCs和TAM MCs.
通过静电吸附,PEI和HA的交替沉积在MC表面上,形成了核心外结构 (DES MCs@(PEI/HA) 3和TAM MCs@(PEI/HA) 3).
进行了体外溶解性,释放性研究,疏水性,安全性和体内疗效评估.

主要成果:

无论是DES MCs@(PEI/HA) 3还是TAM MCs@(PEI/HA) 3都显示出增强的溶解性和持续释放性质.
TAM MCs@(PEI/HA) 3与商用塔克罗利木斯眼滴相比,显示出更高的疗效,允许每天服用一次.
微晶制剂对塔克罗利莫斯的治疗效果比对德甲的治疗效果更为明显.

结论:

在微晶体上PEI/HA的逐层自我组装是改善眼部药物输送的有希望的策略.
开发的TAM MCs@(PEI/HA) 3悬浮眼滴为提高难溶性药物的溶解性和输送提供了有效的解决方案.
这种方法有可能开发出改进的眼科配方,降低剂量频率.

Drug Delivery: Miscellaneous Routes

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs...

Desensitization and Tachyphylaxis

Desensitization and Tachyphylaxis

Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.
