Development of Rapidly Dissolving Microneedles Integrated with Valsartan-Loaded Nanoliposomes for Transdermal Drug Delivery: In Vitro and Ex Vivo Evaluation.

ABSTRACT: Background: Hypertension (HTN) is recognized as a major risk factor for cardiovascular disease, chronic kidney disease, and peripheral artery disease. Valsartan (VAL), an angiotensin receptor blocker drug for hypertension, has been limited due to its poor solubility and poor absorption from the GIT, which leads to low oral bioavailability. Objectives/Method: In the present research, firstly, VAL-loaded nanoliposomes were formulated and optimized using the Box-Behnken design (BBD). Optimized VAL-nanoliposomes were physically characterized and their fate was examined by scanning and transmission microscopy, DSC, FTIR, XRD, and ex vivo studies using rat skin. In vitro studies using human keratinocyte (HaCaT) cells showed a decrease in cell viability as the liposome concentration
