Investigation of a novel 3-fluid nozzle spray drying technology for the engineering of multifunctional layered microparticles.

Ritesh M Pabari et al.

Expert opinion on drug delivery, 9(12), 1463-1474 (2012-10-16)

To examine the potential of a novel 3-fluid nozzle spray drying technology to formulate differentiated layered microparticles (MPs) of diclofenac sodium (DFS)/ethyl cellulose (EC). DFS/EC MPs were formulated using the inner and/or outer nozzles of a novel 3-fluid nozzle and

Microencapsulation of hydroxyzine HCl by thermal phase separation: in vitro release enhancement and in vivo pharmacodynamic evaluation.

Christianne Mounir Zaki Rizkalla et al.

Pharmaceutical development and technology, 18(1), 196-209 (2012-06-06)

The systemic effect of hydroxyzine hydrochloride following its oral administration or topical application is associated with non compliant anticholinergic effect. Subsequently, the present study aims to prepare microcapsules loaded with hydroxyzine hydrochloride enabling its controlled release into the skin and

Study of drug release and tablet characteristics of silicone adhesive matrix tablets.

Gaurav Tolia et al.

European journal of pharmaceutics and biopharmaceutics : official journal of Arbeitsgemeinschaft fur Pharmazeutische Verfahrenstechnik e.V, 82(3), 518-525 (2012-07-24)

Matrix tablets of a model drug acetaminophen (APAP) were prepared using a highly compressible low glass transition temperature (T(g)) polymer silicone pressure sensitive adhesive (PSA) at various binary mixtures of silicone PSA/APAP ratios. Matrix tablets of a rigid high T(g)

Regulating drug release behavior and kinetics from matrix tablets based on fine particle-sized ethyl cellulose ether derivatives: an in vitro and in vivo evaluation.

Kifayat Ullah Shah et al.

TheScientificWorldJournal, 2012, 842348-842348 (2012-06-01)

The design and fabrication of sustained/controlled release dosage forms, employing new excipients capable of extending/controlling the release of drugs from the dosage forms over prolonged periods, has worked well in achieving optimally enhanced therapeutic levels of the drugs. In this

Formulation, in vitro drug release study and anticancer activity of 5-fluorouracil loaded gellan gum microbeads.

S K Sahoo et al.

Acta poloniae pharmaceutica, 70(1), 123-127 (2013-04-25)

5-Fluorouracil loaded calcium-zinc-gellan and calcium-zinc-gellan-ethyl cellulose microbeads were successfully prepared by simple ionotropic gelation and oil in water ionotropic gelation technique, respectively. Prepared microbeads were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and evaluated for particle size, drug

Development of a novel and customizable two-solution mixing type spray nozzle for one-step preparation of nanoparticle-containing microparticles.

Tetsuya Ozeki et al.

Biological & pharmaceutical bulletin, 35(11), 1926-1931 (2012-11-06)

Production of drug nanoparticles is an effective strategy to enhance solubility and oral absorption of water-insoluble drugs. The handling of drug nanoparticles has been an important issue in drug formulation because nanoparticles easily aggregate each other and redispersion of these

Functionalized graphene sheets as a versatile replacement for platinum in dye-sensitized solar cells.

Joseph D Roy-Mayhew et al.

ACS applied materials & interfaces, 4(5), 2794-2800 (2012-05-03)

Several techniques for fabricating functionalized graphene sheet (FGS) electrodes were tested for catalytic performance in dye-sensitized solar cells (DSSCs). By using ethyl cellulose as a sacrificial binder, and partially thermolyzing it, we were able to create electrodes which exhibited lower

Time-engineeringed biphasic drug release by electrospun nanofiber meshes.

Li-Ya Huang et al.

International journal of pharmaceutics, 436(1-2), 88-96 (2012-07-14)

A drug-loaded nanofiber mesh which could achieve time-engineeringed biphasic release was fabricated through sequential electrospinning. The drug to polymer ratio of each single mesh was allocated and designed before the tri-layered meshes were created. The resultant meshes had the following

Genipin crosslinked ethyl cellulose-chitosan complex microspheres for anti-tuberculosis delivery.

Hanzhou Feng et al.

Colloids and surfaces. B, Biointerfaces, 103, 530-537 (2012-12-26)

Genipin-crosslinked complex microspheres made of the combination of two polymers, ethyl cellulose and chitosan, were prepared by spray drying method. Rifabutin, an anti-tuberculosis agent was used as a model drug. Effects of various specifications of ethyl cellulose and chitosan, different

Cellulose and collagen derived micro-nano structured scaffolds for bone tissue engineering.

Aja Aravamudhan et al.

Journal of biomedical nanotechnology, 9(4), 719-731 (2013-04-30)

Scaffold based bone tissue engineering (BTE) has made great progress in regenerating lost bone tissue. Materials of natural and synthetic origin have been used for scaffold fabrication. Scaffolds derived from natural polymers offer greater bioactivity and biocompatibility with mammalian tissues
