Abstract

A simple method to rapidly customize and to also mass produce oral dosage forms is arguably a current bottleneck in the development of modern personalized medicine. Specifically, delayed-release mechanisms with well-controlled dosage profiles for combinations of traditional Chinese herbal extracts and Western medications are not well established. Herein, we demonstrate a novel multidrug-loaded membrane sandwich with structures infused with ibuprofen (IBU) and Ganoderma lucidum polysaccharide (GLP) using three-dimensional electrohydrodynamic printing and electrospinning techniques. The resulting flexible membrane consists of microscaled, multilayered cellulose acetate (CA) membranes loaded with IBU in the shape of either concentric squares or circles, as the top and bottom layers of a sandwich structure. In between the CA-IBU layers are randomly electrospun polyvinyl pyrrolidone (PVP) layers loaded with GLP. The complete fibrous membrane sandwich can be folded and embedded into a 0-size capsule to achieve oral compliance. Simulated in vitro testing of gastric and intestinal fluids demonstrated a triphasic release profile. There was an immediate release of GLP after gastric juices dissolved the capsule shell and the PVP, followed by the short-term release of 60% of the IBU within an hour afterward, and the remaining IBU was released in a sustained manner following a Fickian diffusion profile. In summary, this multidrug (both hydrophilic and/or hydrophobic) oral system with precision-designed structures should enable personalized therapeutic dosing.
