Development of novel spray coated soft elastic gelatin capsule sustained release formulations of nifedipine, bioavailability and bioequivalence of verapamil HCL controlled release formulations, pharmacokinetics of terbinafine after single oral doses in raptors

Creator:: Fahmy, Sahar Abd El-Sattar
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...

In vitro and in vivo testing of a gastric retention device : development and evaluation of a new colonic delivery system

Creator:: Ahmed, Iman Saad
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...

Bioadhesive polymers in drug product formulations

Creator:: Tavipatana, Wattanaporn
Abstract:: Gastric retention time of single unit dosage forms in swine was found to be much longer than in humans. It was concluded that swine are not a good animal model to study GI transit time of nonerodable or slowly eroded dosage forms. Noneradable and slowly eroded dosage forms used to...

Pharmacokinetic modeling and simulations of gastrointestinal transit effects on drug pharmacokinetics from enteric-coated pellet formulations and their applications

Creator:: Watanalumlerd, Prapoch
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...

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...

Development and in vivo testing of a gastric retention device (GRD) in dogs

Creator:: Kapsi, Shivakumar G.
Abstract:: This thesis describes 1) development of a gastric retention device (GRD) to increase gastric retention time of certain drugs, 2) product formulations of an immediate release itraconazole and controlled-release ketoprofen. GRD was fabricated from crosslinked carbohydrate polymers. Rate and extent of hydration of the film in water and in simulated...

Development of Hot-melt Pan-coating, Application to Sustained-release Capsules and Tamper Resistant-coating. 2) Formulation of Verapamil HCl and Diltiazem HCl Semisolid Matrix Capsules. 3) Novel Sustained Release Tablet of Glipizide: Compression of Coated Drug Beads, Formulation, Dissolution, and Convolution. 4) Verapamil Sustained Release: New Formulation and Convolution

Creator:: Nguyen, Chien Ngoc
Abstract:: Hot-melt pan-coating, which is a novel coating method and takes 2-3 hours for 300 mg coating weight gain per capsule and tamper-resistant coating, which takes 30 minutes, is much faster than tedious sugar coating and allows greater coating weight gains in shorter times than spray-melt coating. Although hot-melt pan coating...
