The present study is the development of colon targeted matrix tablets of the drug flurbiprofen, a NSAIDS of the class of Ibuprofen designed to prolonged the release for sustained effect. Different formulation (F1 TO F9) batches were made with the help of different polymers and their different proportions (Guar Gum, Eudragit RL, Eudragit RS ) with the help of Wet granulation techniques. The prep...

The objective of the present investigation was to prepare and evaluate ocular inserts of moxifloxacin. An ocular insert was made from an aqueous dispersion of moxifloxacin, sodium alginate, polyvinyl alcohol, and dibutyl phthalate by the film casting method. The ocular insert (5.5 mm diameter) was cross-linked by CaCl2 and was coated with Eudragit S-100, RL-100, RS-100, E-100 or L-100. The in v...

The present study was undertaken to 1) formulate a pulsatile colonic delivery of simvastatin (SIM) as chronotherapy for treatment of hypercholesterolemia, and 2) enhance the dissolution profile of the prepared SIM chronotherapeutic system. Lipid based formulations were utilized to formulate SIM in capsule dosage form coated with Eudragit® S100. SIM was formulated using different percentages of ...

dependent variables that were selected for study were, particle size (Y ) and % drug entrapment (Y ). The derived 1 2 polynomial equations were verified by check point formulation. The application of factorial design gave a statistically systematic approach for the formulation and optimization of nanoparticles with desired particle size, % drug release and high entrapment efficiency. Drug:polym...

In the present work, monolithic matrix transdermal systems containing Drug x were prepared using various ratios of the polymer blends of hydroxy propyl methyl cellulose (HPMC) and Eudragit S 100 (ES) with triethyl citrate as a plasticizer. A 32 full factorial design was employed. The concentration of HPMC and ES were used as independent variables, while percentage drug release was selected as d...

The objective of this investigation was to develop the hollow microspheres as a new dosage form of floating drug delivery system with prolonged stomach retention time. Hollow microspheres containing ranitidine hydrochloride were prepared by solvent evaporation method using Eudragit RLPO dissolved in a mixture of dichloromethane and ethanol. The maximum yield and drug loading amount of hollow mi...

We previously prepared and evaluated simple Eudragit S100 microparticles loaded with prednisolone (ES-MP) and Eudragit S100-coated chitosan-succinyl-prednisolone conjugate microparticles (Ch-MP/ES) in vitro. In this work, the effectiveness, toxic side effects (5 mg prednisolone (PD) eq/kg × 3 d, 10 mg PD eq/kg × 3 d), and pharmacokinetic characteristics (5 mg PD eq/kg) were examined using rats ...

objective(s): 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 obtain...

Objective: Sonneratia alba leaves were used by the community for traditional medicine to cure muscle pain, back antioxidants, rheumatism, malaria, wounds, tuberculosis (TB) and as a spermicide. S. extract was easy damage because of light exposure, change pH, weather long period storage time. The problem can be solved coating with microencapsulation technique. purpose this research formulate mic...
