This paper presents a drug delivery system based on alginate microspheres. The biocompatibility, the flexibility in size and shape, the ability to entrap biomolecules as well as cells make alginate based systems ideal for in vivo drug delivery. Specifically, considering the target application of neural regeneration and the issue of neuroprotection for the development of innovative neuroprosthes...

Many active pharmaceutical ingredients (APIs) face the challenge of palatability when administered orally. Tastemasking technologies often utilize coatings to help palatability but these coatings or agglomerations can negatively impact bioavailability. Orbis Biosciences, Inc. (Orbis) has developed a novel taste-masking technology that has previously been demonstrated to have virtually complete ...

The floating microsphere's purpose is to improve gastric retention time. Floating drug delivery systems are lower in bulk thickness than juice and remain on for a long period of time without impacting the gastric-emptying rate increasing bioavailability. Gastro-retentive microspheres particularly suitable continuous or late release oral formulations with blending versatility achieve various pat...

Micro- and nanospheres composed of biodegradable polymers show promise as versatile devices for the controlled delivery of biopharmaceuticals. Whereas important properties such as drug release profiles, biocompatibility, and (bio)degradability have been determined for many types of biodegradable particles, information about particle degradation inside phagocytic cells is usually lacking. Here, ...

The purpose of this work was to introduce a new concept of coated pellets containing chitosan microspheres loaded with didadosine for oral administration, aiming at reducing the frequency of administration and improving the bioavailability by a suitable release profile. Chitosan microspheres were produced under fluidized bed, followed by extrusion and spheronization to obtain pellets with a mea...

BACKGROUND AND OBJECTIVES To achieve better therapeutic benefits of local anesthetics in the control of postoperative pain through controlled-release carrier. The objective of this study was to compare the characteristics of sensory and motor blockade between microspheres without local anesthetic: racemic bupivacaine-loaded microspheres; 50% enantiomeric excess bupivacaine-loaded microspheres; ...

in the present study, sodium alginate microparticle for oral delivery of furosemide was designed whether the encapsulation into microparticles might improve the oral absorption of this potent loop diuretic. we described preparation of microspheres based on ionotropic gelation method and characterized its physicochemical properties. to acquire an optimum formulation, a generalized regression neu...

Protein ligands were conjugated to the surface of biodegradable microspheres. These microsphere-ligand conjugates were then used in two in vitro model systems to evaluate the effect of conjugated ligands on microsphere behavior. Microsphere retention in agarose columns was increased by ligands on the microsphere surface specific for receptors on the agarose matrix. In another experiment, conjug...

Inflammatory bowel disease (IBD) is a chronic relapsing and remitting inflammatory disorder of the small intestine colon. IBD includes ulcerative colitis (UC) Crohn’s (CD), it main reason for expansion colon cancer, referred to as colitis-associated cancer (CAC). Oral colon-targeted microsphere based drug delivery system containing sulfasalazine was prepared, optimized characterized. The micros...
