Hydrogel-Forming Microneedles Prepared from “Super Swelling” Polymers Combined with Lyophilised Wafers for Transdermal Drug Delivery.
Abstract. Hydroxypropylmethylcellulose (HPMC) represents the most frequently used polymer in the formulation of hydrogel matrices for controlled drug delivery.
From a drug delivery perspective, polymer devices can be categorized as diffusion-controlled (monolithic devices), solvent-activated (swelling- or ...
Hydrogels are hydrophilic polymers that absorb high amounts of water and its increased use in the drug delivery systems formulations is based on its ability to ...
Shift in pH causes change in the charge on the polymer chains leading to swelling and drug release. Poly(acrylic acid), Guar gum succinate, ...
Hydrogels have been used by many investigators in controlled-release drug delivery systems because of their good tissue compatibility and easy manipulation ...
