Author’s E-mail: [email protected] Tel:+964-7702660991 In an attempt to combine the favourite properties of hard gelatine capsules with the protective and controlled release properties of enteric coating to get an appropriately and acceptably formulated enteric coated hard gelatine capsules with pH dependent drug release characteristic. Two hard gelatine capsule sizes were selected i.e. siz...

The present study in formulation and evaluation of Mebeverine hydrochloride micropellets. Mebeverine hydrochloride which is used as a anti spasmodic drug to treat irritable bowel syndrome. The pellets were prepared by pan coating powder layering method by using nonpareil seeds in core pellets and were coated with HPMC K4M, Eudragit S100 and Eudragit L100 in different ratios to form a film coat ...

Pefloxacin mesylate is a flouroquinolone antibacterial drug effective in the treatment of bacterial conjunctivitis. The objective of the present work was to develop ocular inserts of pefloxacin mesylate and evaluate their potential for sustained ocular delivery. Reservoir-type ocular inserts were prepared by the film casting technique in teflon coated Petri dishes and characterized in vitro by ...

Hot melt extrusion has gained considerable attention as a novel technique for taste masking of bitter APIs. The aim of this study was to investigate whether hot melt extrusion could be used to develop taste masked formulations of isoniazid and also to evaluate and correlate different taste assessment methods Two polymers with different physico-chemical properties, Soluplus and Eudragit E-PO wer...

The aim of this study was to develop an alternative method for enteric coating of HPMC capsules that avoids the sealing step before coating, resulting in ready-to-use enteric-coated capsules for the use in retail or hospital pharmacy or R&D sections of pharmaceutical industry and for the production of enteric-coated heat and moisture sensitive biomaterials. HPMC caps and bodies 00 (Vcaps, Capsu...

The purpose of this study was to investigate the influence of sodium bicarbonate on the physicochemical properties of controlled release hot-melt extruded (HME) tablets containing Eudragit RS PO and/or Eudragit E PO. Acetohydroxamic acid and chlorpheniramine maleate were used as model drugs. Sodium bicarbonate was incorporated into the tablet formulations and the drug release properties and buo...

Sorafenib is slightly absorbed in the gastrointestinal tract due to its poor solubility in water. To improve its absorption, a novel nanoparticulate formulation-nanomatrix was used in the study. The nanomatrix was a system prepared from a porous material Sylysia(®) 350 and a pH sensitive polymer Eudragit(®). The formulations were optimized by orthogonal design (L(9)(3(4))) and their bioavailabi...

The aim of this study was to prepare and evaluate microspheres containing ibuprofen. Microspheres were prepared by modified quasi-emulsion solvent diffusion method. The influence of formulation factors (drug-polymer ratio, volumes of solvent, polyvinyl alcohol concentration and type of polymer) on the morphology, particle size distribution, drug loading capacity, micromeritical properties and t...

The objective of the present work was to develop a suitable transdermal drug delivery system for nitrendipine. Polymeric films of nitrendipine were prepared by the film casting technique (glass ring) on mercury substrate. They were evaluated for physicochemical parameters, in vitro release and ex vivo permeation (heat separated human epidermis). Release of the drug from the films followed anoma...

buccal mucoadhesive films have attracted great attention among mucoadhesive systems due to their ability to adhere and remain on the oral mucosa and to release their drug content gradually. the aim of the current study was to formulate the ziziphus jujuba aqueous extract as buccal bioadhesive film, which continiously releases the drug at sufficient concentration for reducing the frequency of th...
