Size of the pellets was determined by sieve shaker analysis. The angle of repose was measured eucragit funnel with 6 mm diameter orifice 20 g of pellets were placed in funnel and allowed to fall 4 cm onto a hard level surface. Twenty grams of pellets were poured gradually through a funnel in to 50 ml graduated cylinder, tapped lightly on hard surface and the volume eudraagit.

A burst effect has so far not been reported with multiparticulate systems. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error.

Eufragit cellulose PH has been found to be an effective diluent in extrusion spheronization. Acrylates Copolymer Information provided by Evonik. At lower speed rpm dumbbell shaped and irregular pellets were observed. There was a problem providing the content you requested Fluidized bed coater performed enteric coating. Eudragit has a tendency to swell and form a lump in the basket due to which pellets were not properly exposed to the dissolution media.

Acrylates L Information provided by Evonik Vendors: In order to avoid the gastric irritation and degradation of drug in upper gastro intestinal tract, above developed pellets were further coated with enteric polymer.

A speed of rpm was selected as optimized speed for the production of spherical and smooth surface pellets. Subcoating has been proposed by many scientists [ 4 — 6 ] as a method to improve the acid resistance for enteric coated dosage forms. Pellet size and size distribution was determined for coated pellets with different weight gain and it was found to be eudragt in distribution fig.

Users requiring more precise data for scientific or engineering calculations euddagit click on the property value to see the original value as well as raw conversions to equivalent units.

The total out put of extrudate is mainly governed by the extrusion speed. Surface morphology of developed pellets were investigated under scanning electron microscope which revealed a smooth and spherical surface fig. The percentage friability was calculated from the pellet weight before and after fluidization [ 8 ]. All the reagents and solvents used were of analytical grades. Processing parameters are given in Table 1. The extrudates was spheronized for 2 min in Fauji Paudal mearumerizer [ 7 ].

Pellets were coated with Eudragit L 30 D using fluidized bed processor. The acrylic polymer coating suspensions were prepared by adding water to the commercially available Eudragit L30 D Glcerylmonostearate dispersion in methylene chloride was used for this purpose and was prepared by adding the eudragif to the solvent. It is a milky-white liquid of low viscosity with a faint characteristic odor. The coated pellets were kept in glass dishes and stored in a closed container at ambient eudratit.

Process conditions and parameters used for preparation of g batch of optimized pellets. Questions eudrahit comments about MatWeb? The dry ingredients were combined and mixed in twin-shell blender for 20 min and then transferred d55 planetary mixture where the aqueous binder solution prepared with HPMC E5, was slowly added.

All the three are cationic copolymer based on dimethylaminoethyl methacrylate, butylmethacrylate and methyl methacrylate. Chemically they are known as poly butyl methacrylate-co- 2-dimethylaminoethyl methacrylate-co-methyl methacrylate. They are soluble in gastric pH up to 5. Low viscosity, high pigment binding capacity, good adhesion and low polymer weight gain are the characteristic properties of Eudragit E series. They are commonly used in film coating, odor and taste masking, moisture and light protection. They differ from each other in terms of their physical appearance.

Table 3: Formulae for different pellets Size distribution of uncoated pellets Size of the pellets was determined by sieve shaker analysis. Shaker was shaken for 20 min, particles retained on different sieves were collected and average pellets size was determined. Pellet friability The friability of the uncoated pellets was determined by inserting 20 g sample of pellets inside a fluidized bed unit fitted with a Wurster insert. The pellets were fluidized for 15 min. Pellets were then transferred from the fluidized bed and the residual powder was removed prior to recording the final weight. The percentage friability was calculated from the pellet weight before and after fluidization [ 8 ]. Angle of repose The angle of repose was measured using funnel with 6 mm diameter orifice 20 g of pellets were placed in funnel and allowed to fall 4 cm onto a hard level surface.
