conclusions it was shown that combination of pectin and eudragits can relatively control drug release in the upper gi. on the other hand, pectin degraded in the presence of pectinase and formulations were susceptible to the colonic media. results it was shown that in the presence of pectin, formulations without erl had a relative resistance to drug release in sgf. pellets containing pectin and ...

OBJECTIVES Ketotifen fumarate (KF) is a selective and noncompetitive histamine antagonist (H1-receptor) that is used topically in the treatment of allergic conditions of rhinitis and conjunctivitis. The aim of this study was to formulate and improve an ophthalmic delivery system of KF. Ocular nanoparticles were prepared with the objective of reducing the frequency of administration and obtainin...

Polymers constitute the major part of pharmaceutical formulations functionality and significance. Development of novel drug delivery system (NDDS) has been made possible by eudragit polymers to modify the release pattern of drug. The basic objective of sustained drug release is to achieve more effective therapies by eliminating potential for both under and overdosing. Other advantages include m...

In the present study, a capsule formulation composed of enteric coated granules of Lactobacillus acidophilus ATCC 4962 was developed using Eudragit L30D-55 as enteric polymer. Optimization of the capsule formulation was achieved with a maximum viable cell count after 2 h of incubation in acid medium and disintegration time of 1 h in buffer pH 6.8. The amount of Eudragit L30D-55 in the capsules ...

In this paper, different formulation types of microparticulate systems such as beads, microbeads, microspheres and microsponges using to special attention chitosan, alginate and eudragit RS 100 are reviewed. Chitosan and alginates are natural, anionic or cationic, biocompatible, biodegredable and non-toxic polymers. They have excellent potential for pharmaceutical and biopharmaceutical applicat...

In an era moving towards digital health, 3D printing has successfully proven its applicability in providing personalised medicine through a technology-based approach. Among the different techniques, direct extrusion been demonstrated as promising approach for on demand manufacturing of solid dosage forms. However, it usually requires use elevated temperatures and/or incorporation evaporable sol...

This study investigates the application of poly (2-ethyl-2-oxazoline) (PEtOx) as main matrix for development solid oral tablets with extended release profile using hot-melt extrusion (HME) coupled fused deposition modeling (FDM) three-dimensional (3D) printing techniques. Acetaminophen (APAP) was used model drug. Different grades PEtOx and polymers (ethylene oxide) (PEO) Eudragit® RL PO (ERL) w...

The effect of Eudragit RSPO on the photostability venlafaxine in a physical mixture and as melt was studied. A validated ultra-high-performance liquid chromatography mass spectrometry method used to determine content alongside degradation products. most likely structures products were determined by spectrometry. samples evaluated before after exposure ultraviolet differential scanning calorimet...

The present investigation involves formulation and evaluation of microspheres with Repaglinide as model drug for prolongation of drug release time. An attempt was made to prepare microspheres of Repaglinide by Quasi emulsion solvent diffusion technique, with a view to deliver the drug at sustained or controlled manner in gastrointestinal tract and consequently into systemic circulation. The mic...
