Pharmacokinetic/pharmacodynamic modeling/simulation and novel gastric retention formulation

Creator:: Kwon, Hyojong
Abstract:: This dissertation describes formulation of a gastric retention device (GRD) and sustained release (SR) hydrochlorothiazide beads at Oregon State University. Formulation condition and amounts of excipients had significant influence on characteristic of the GRD. The GRD containing SR hydrochlorothiazide beads was employed to assess bioavailability/bioequivalency study in healthy subjects. An...

Calcium alginate gels in oral dosage form design

Creator:: Lin, Shun Yih
Abstract:: In vivo research following ingesting of commercially available Lactobacillus tablets, which contain about 2X10⁶ cfu/tablet of Lactobacillus acidophilus and Lactobacillus bulgaricus cells in a dose of four tablets daily, showed serum lipoprotein concentrations did not change significantly. In order to increase the number of viable Lactobacillus bacteria after challenging in...

Evaluation of gastrointestinal transit time and novel oral acetaminophen product formulation

Creator:: Hossain, Mohammad
Abstract:: Gastrointestinal (GI) transit data were collected using pigs as animal models. Density and size effects of non-disintegrating dosage forms on GI transit were investigated. Total GI transit times range from 2 to 33 days for 22 administrations of these nondisintegrating dosage forms. Pigs are found to not be an appropriate...

Tablet shapes and in vitro evaluation of coated hydrophilic matrix tablets novel mupirocin formulations non-acidic enteric coating of omeprazole and novel hot-melt coating process

Creator:: Leung, Manshiu
Abstract:: This dissertation is comprised of four distinct formulation sections, which are described below: A novel solid dosage formulation was investigated for achieving zero-order drug release profile by combining tablet shape design and tablet membrane film coating. Verapmail (model drug) was compressed into hydrophilic matrix tablet cores of flat-faced and bi-convex...

Pharmacokinetics of dyphylline after administration of prodrugs in rabbits and pigs

Creator:: Huang, Hua-pin
Abstract:: Dyphylline is an analogue of theophylline and the latter is the most popular member of the methyixanthine family in use for the treatment of asthma. Although dyphylline is devoid of some problems associated with theophylline, a reported short half-life for dyphylline (2.1 hours) has made its clinical usefulness limited. In...

Development and in vivo testing of novel hydrochlorothiazide gastric retention formulations in healthy volunteers and stage I hypertensive patients

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...
