背景情况:
- 糖尿病病 (DKD) 是一种严重的糖尿病并发症,导致衰竭.
- 目前对DKD的治疗方法有限,需要新的治疗策略.
- 酸 (FRA) 是一种天然化合物,具有治疗潜力,但其口服生物可用性较差.
研究的目的:
- 通过开发一种新的透皮,脏向的塑配方,增强ferulic acid (FRA) 治疗糖尿病病 (DKD) 的疗效.
- 通过纳米体输送系统,克服FRA口服生物利用度较低的局限性.
- 研究目标纳米载体在改善DKD病理生理学的潜力.
主要方法:
- 使用Span 60和Labrasol制定了Spanlastic (SP) 纳米纤维,用酸或酸 (HA) 作为涂层.
- 配方进行了优化,使用了2^1 x 3^1因数设计,重点关注捕获效率,粒子大小和泽塔潜力.

Modified-Release Drug Delivery Systems: Site-Targeted
Site-targeted drug delivery systems enhance therapeutic efficacy while minimizing systemic toxicity and treatment costs. Unlike conventional methods, these systems ensure precise drug delivery, improving bioavailability and reducing side effects. Targeted drug delivery is classified into three levels. First-order targeting directs drugs to the capillary beds of specific organs or tissues. Second-order targets specific cell types, such as tumor cells, using receptor-mediated interactions.
Transdermal Drug Delivery Systems
Transdermal drug delivery systems (TDDS) enable the controlled release of drugs across the skin into systemic circulation. They are particularly advantageous for drugs with short half-lives or narrow therapeutic indices, as they maintain consistent plasma concentrations and reduce the risk of subtherapeutic or toxic levels.TDDS are categorized into monolithic, reservoir, and mixed systems. Monolithic systems embed the drug in a polymer matrix, where diffusion governs release. Reservoir systems...
Diabetic Nephropathy
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
