Abstract:: Effects of gastrointestinal transit on plasma concentrations of drugs from enteric-coated pellet formulations were demonstrated using pharmacokinetic models describing plasma concentrations of drugs from various enteric-coated pellet formulations. Gastric emptying time, lag time of emptying, and drug release rate from pellets in the small intestine, along with other pharmacokinetic parameters...

Abstract:: This dissertation describes two different projects. The first is the development of an oral DNA vaccine delivery system for fish. A novel oral DNA vaccine delivery system was developed for Rainbow Trout by combining non-viral vectors (polycationic liposomes or polycationic polymer) to facilitate the DNA vaccine's uptake by cell membranes...

Abstract:: This thesis describes evaluation of a gastric retention device (GRD) developed at Oregon State University. The device was originally fabricated from Xanthan gum and Locust bean gum. A modified gastric retention device containing other additives was developed and investigated in this work. The modified device was evaluated in vitro for...

Abstract:: Quinolinate (QUIN) is an endogenous neurotoxic product of the kynurenine pathway of tryptophan metabolism. Quinolinate is a selective agonist of the NMDA family of glutamate receptors and, as such, may play a role in the pathology of a number of major central nervous system (CNS) disorders. These include both chronic...

Abstract:: This dissertation describes the development of a new sustained release formulation of nifedipine. The new formulation was developed by coating commercially available immediate release soft elastic gelatin capsules using a spray coating technique with two different polymeric combinations. Dissolution studies were conducted and showed that controlled release of nifedipine was...

Creator:: Farid, Samar Farghali
Abstract:: This thesis describes in vitro and in vivo evaluation of a gastric retention formulation (GRF) developed at Oregon State University. The formulation was prepared from xanthan gum and locust bean gum as gelling agents and other formulation ingredients were added, then it was originally vacuum oven dried. The effect of...

Creator:: Taur, Jan-Shiang
Abstract:: The goal of this dissertation is to investigate the interaction between cimetidine and dietary flavonoids using the Caco-2 cell transport model. It has been shown that flavonoids can change the bioavailability of pharmaceuticals, either by inhibiting metabolizing enzymes or inhibiting the drug efflux transporters. However, the effect of dietary flavonoids...

Creator:: Rakkanka, Vipaporn
Abstract:: This thesis describes evaluation of a novel self-sealing chewable sustained release tablet that can maintain controlled release of drug regardless of compaction, crushing, or chewing. The new formulation contains polyethylene oxide which produces a sealant effect for cracks produced in the polymer coating during compaction. Dissolution studies were conducted and...
