The aim of the present research was to formulate taste masked orally disintegrating tablets (ODTs) of ondansetron (water insoluble) and sumatriptan succinate (water soluble) using different available technologies namely Orasolv, freeze drying and Wowtab. In Wowtab and freeze drying techniques, the bitter taste of ondansetron was masked by the addition of a sweetener (aspartame), whereas in the ... promising copolymer called Eudragit® EPO was selected as a carrier to prepare taste masked microspheres. It is a pH dependent material and is only soluble at a pH below 5.5, by taking the advantage of this unique property, we can prevent the release of … HCl, C-DHCl, kyron T- (polacrillin potassium), Eudragit EPO, mannitol, sorbitol, MCC, kyron T- , sucralose, chocolate avor, and xanthum gum ( Table ).

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. The Resveratrol–Eudragit® EPO system exhibited good miscibility and significant dissolution enhancement. Resveratrol in the amorphous solid dispersion existed in an amorphous state and had molecular interactions with Eudragit® EPO. Stability studies showed no apparent difference in the physical state of the solid dispersion after 6 months.

Eudragit RS to around the body temperature (32—42°C), PEG 400 was used as a plasticizer in this study. The DSC curves of Eudragit RS, EPG containing 5% PEG 400 and 10% PEG 400 by weight (5% EPG and 10% EPG, respec-tively) are shown in Fig. 1; a jump of heat capacity and an anomalous endothermic peak (the maximum of heat capac-ity) can be seen. Potential applications of a novel system composed of two oppositely-charged (meth)acrylate copolymers, Eudragit® ЕРО (EPO) and Eudragit® S100 (S100), loaded with indomethacin (IND) in oral drug delivery were evaluated. The particles based on drug-interpolyelectrolyte complexes (DIPEC), (EPO-IND)/S100, were prepared by mixing aqueous solutions of both copolymers at fixed pH.

Indomethacin (INM) is used as model API; Eudragit® EPO (EPO) is used as polymer excipient; AcDiSol and Crospovidone (Cros) are used as two kinds of disintegrant. The main objectives are to gain an understanding of the resulting morphologies, as well as the India. Eudragit® EPO, Eudragit ® RS and Eudragit RL were obtained as gift samples from Evonic Degussa India Pvt. Ltd., Mumbai. Polyvinyl alcohol, methanol and dichloromethane were purchased from Merck Specialties Pvt. Ltd., Mumbai, India. All other chemicals were of … eudragit EPO was used as it was previously reported to have taste masking properties. For preliminary trials drug free patches were prepared with eudragit EPO, PVA, HPMC E 5 LV and HPMC E 15 LV at 2% w/v, 4% w/v, 6% w/v, 8% w/v and 10% w/v concentrations in 0.1N HCl. These solutions were plasticized using 2% w/v glycerin. furosemide, Eudragit RL-100, RS-100 and Drug coat L-100, S-100 at different drug-to-polymer ratios were dissolved in 15ml of methanol as shown in Table 1. The solution was stirred at room temperature for 10 mins, and the solvent was then evaporated at room temperature. Solid residue was dried in a … Eudragit EPO. Formulations compositions are mentioned in table 4.1. Ethanol was added to each mixture. Then gel was prepared using the mixture of the drug and Eudragit EPO which was converted into the taste-masked granules by the extrusion method. The prepared gel was manually extruded (pressed out) using a syringe. After a poorly water-soluble drug) by developing CAR-eudragit® RS100 (Eud) nanofibers and nanobeads benefiting an electrospraying approach. Materials and Methods: CAR-Eud nanoformulations with varying ratios (1:5 and 1:10) at total solution concentrations of 10 %, 15 % and 20 % w/v were formulated. Abstract. Hot-melt extrusion (HME) is one of the most widely used technologies in the plastic, rubber and food industries and it has also been extensively explored and used in aca
Eudragit EPO (EPO). The solid dispersions were prepared by solvent evaporation method. The prepared solid dispersions showed an enhancement in dissolution rate and solubility compared to API. In vitro release profiles of all SDs were comparatively evaluated. Faster dissolution was exhibited by solid dispersion containing 1:4 ratio of crospovidone (4.45%w/v), Eudragit EPO (4.45%w/v), Hydroxypropyl cellulose (4.45%w/v) and Talc (0.8%w/v) in a fluidized bed coater. The methacrylate copolymer Eudragit EPO is highly suitable for taste masking, showing taste masking properties even at a low thickness. The coated granules, which were white to off white in colour, were Films produced by Eudragit EPO, Eudragit E 100, Eudragit RL 100, and Eudragit RS 100 cannot be washed away with water. In contrast, Eudragit S100 provides a film that can be removed with water after being applied to the skin. This is because Eudragit S100 can dissolve above pH 7. Eudragit S100 also does not cause any skin irritation. 20 the GXR-35. 400g of Eudragit E PO was loaded into the powder feeder and dry coated onto the drug loaded spheres using two binding/plasticizing solutions: 10% Triethyl Citrate (TEC) and 10% Dibutyl Sebacate (DBS) in water. Tween 80 was added to both solutions at a 0.5% level as an emulsifying agent. Samples were taken at 100g, 200g, 300g and 400g of Eudragit® EPO was the one of biocompatible polymer which could dissolve in this eutectic system up to 40% w/w with no chemical interaction of each compound.
