The aim of the current investigation is to study the kinetics of drug release pattern from buccal swellable, controlled release tablets of amoxicillin trihydrate. Buccal tablets were prepared with modified gum karaya in 5-20% concentration. Drug release from the formulated amoxicillin trihydrate loaded buccal tablets followed Zero order kinetics resulting in regulated and controlled release for...

Purposes: Propranolol HCl is a beta blocker commonly used worldwide; however, it shows a low bioavailability due to its extensive first-pass metabolism. To solve this problem, a novel drug delivery system such as buccoadhesive system might be helpful. The aim of the present investigation is to prepare the buccoadhesive tablet of propranolol HCl using different mucoadhesive polymers. Method: Buc...

In this work the enhancing effect of cyclodextrins on the buccal permeation of a hydrophobic model drug, omeprazole was studied. First, the influence of the complexation with cyclodextrins in the absence and in the presence of an alkali agent, L-arginine, on the drug stability was checked at neutral conditions since omeprazole alone is only stable in basic conditions. In vitro transbuccal perme...

Annealed and non-annealed freeze-dried wafers from synthesised thiolated-chitosan have been developed and evaluated. Wafers were obtained by freeze-drying aqueous gels of the thiolated polymer incorporating per polymer weight, 10 % each of glycerol as plasticizer, D-mannitol as cryoprotectant and 50% BSA as model protein drug. The formulation was freeze-dried with or without the process of anne...

The objective of the present study was to prolong the delivery of the active drug in the oral cavity using a suitable carrier such as in situ gel which can effectively deliver the drug for an extended duration of time hence not only reduce the systemic side effects but also improve the therapeutic efficacy, patient compliance. Buccal drug delivery systems are better suitable for antifungal drug...

objective(s): in a new approach, following the development in metal oxide chemistry, the ibuprofen as low water soluble nonsteroidal anti-inflammatory drug diffused into synthetic sol-gel derived nano porous g-alumina by an impregnation method in order to increase the solubility and control the drug release in physiological environment. methods: sol-gel method was utilized for the fabrication o...
