pegylated polypropyleneimine (ppi) dendritic scaffold was used for the delivery of an anti-leukemic drug, imatinib. the current study evolves and emerges the use pegylated ppi dendritic scaffold for the delivery of this drug. in this imatinib was synthesized and loaded with pegylated ppi dendritic scaffold. parameters such as ft-ir, nmr, sem, drug release, dsc and hemolytictoxicity are required...

AIM To examine the in-vitro transport route of tetramethylpyrazine (TMP) across porcine buccal mucosa and to investigate the effects of drug concentration, pH in donor chamber, and 1-octanol/buffer partition coefficient on transbuccal permeation. METHODS In-vitro permeation of TMP through porcine buccal mucosa was studied by using in-line flow through diffusion cells at 37 . The permeability ...

in the long-term management of ulcerative colitis patients, repeat dosing maybe required. since 5-asa is largely absorbed from the upper intestine, selective delivery of drugs into the colon may be regarded as a better method of drug delivery with fewer side effects and a higher efficacy. the aim of this study was to prepare and evaluate a double coated multiparticulate system for 5-asa deliver...

in this study, microspheres containing estradiol valerate were prepared by solvent evaporation method using poly (glycolide-co-lactide) (plga 50:50) and poly (lactide). the effect of different process variables such as polymer type, drugpolymer ratio, stirring rate, volume of internal phase and temperature of external phase on the morphology, particle size distribution, encapsulation efficiency...

orally disintegrating tablets (odts) are capable of turning quickly into a liquid dosage form in contact with the saliva, thus possessing the advantages of both the solid dosage forms particularly stability and liquid dosage forms specially ease of swallowing and pre-gastric absorption of drug. the aim of this study was to prepare a novel matrix-type buccal fast disintegrating ibuprofen tablet ...

abstractgene therapy is a therapeutic approach to deliver genetic material into cells to alter their function in entire organism. one promising form of gene delivery system (dds) is liposomes. the success of liposome-mediated gene delivery is a multifactorial issue and well-designed liposomal systems might lead to optimized gene transfection particularly in vivo. liposomal gene delivery systems...

the present work was aimed to design and develop self-nanoemulsifying drug delivery systems (snedds) with the objective to overcome the problems associated with the delivery of talinolol, a hydrophobic and poorly bioavailable drugs having ph dependant solubility. the solubility of talinolol in various oils, surfactants, cosurfactants and aqueous phases were determined to identify and select the...

in the present study, floating drug delivery beads (fdds) were prepared with sodium alginate/ starch blend as a matrix, sodium hydrogen carbonate as a pore forming agent, methyl cellulose as a binder and barium chloride solution as a hardening agent. in order to prepare the beads with different porosity and morphology the ratio between pore forming agent to polymer blend and ratio of the consti...
