Hydrogel-Forming Microneedle Arrays for Enhanced Transdermal Drug Delivery
Unique microneedle arrays prepared from crosslinked polymers, which contain no drug themselves, are described. They rapidly take up skin interstitial fluid upon skin insertion to form continuous, unblockable, hydrogel conduits from attached patch-type drug reservoirs to the dermal microcirculation. Importantly, such microneedles, which can be fabricated in a wide range of patch sizes and micron...
متن کاملFabrication of polymeric microneedle arrays containing Amphotericin-B for transdermal drug delivery
Background and Aim: Drug delivery through the microneedle array has been considered as an easy and non-invasive method in recent years. The purpose of this study was to design and construct an array of biodegradable polymeric microneedles containing Amphotericin-B to introduce this system and its use in the treatment of cutaneous lesions caused by Leishmania major parasite inoculation as a mode...
متن کاملMicrowave‐Assisted Preparation of Hydrogel‐Forming Microneedle Arrays for Transdermal Drug Delivery Applications
1A microwave (MW)-assisted crosslinking process to prepare hydrogel-forming microneedle (MN) arrays was evaluated. Conventionally, such MN arrays are prepared using processes that includes a thermal crosslinking step. Polymeric MN arrays were prepared using poly(methyl vinyl ether-alt-maleic acid) crosslinked by reaction with poly(ethylene glycol) over 24 h at 80 °C. Polymeric MN arrays were pr...
متن کاملHydrogel-Forming Microneedle Arrays Made from Light-Responsive Materials for On-Demand Transdermal Drug Delivery.
We describe, for the first time, stimulus-responsive hydrogel-forming microneedle (MN) arrays that enable delivery of a clinically relevant model drug (ibuprofen) upon application of light. MN arrays were prepared using a polymer prepared from 2-hydroxyethyl methacrylate (HEMA) and ethylene glycol dimethacrylate (EGDMA) by micromolding. The obtained MN arrays showed good mechanical properties. ...
متن کاملCharacterization of Polymeric Microneedle Arrays for Transdermal Drug Delivery
Microfabrication of dissolvable, swellable, and biodegradable polymeric microneedle arrays (MNs) were extensively investigated based in a nano sensitive fabrication style known as micromilling that is then combined with conventional micromolding technique. The aim of this study was to describe the polymer selection, and optimize formulation compounding parameters for various polymeric MNs. Inve...
