Solubility parameters were employed to determine the wetting properties of the PEG primer. Acta Pharm Hung May;60 Preliminary trials were undertaken to optimize the type of Eudragit and its various levels. Influence of processing parameters and formulation factors on the drug release from tablets powder-coated with Eudragit L Development of Denticap, a matrix based sustained release formulation for treatment of toothache, dental infection and other gum problem.

The effect of storage conditions on the release of drug from coated pellets was determined as a function of the pH of the dissolution medium.

Development and in vitro evaluation of mesalamine delayed release pellets and tableted reservoir-type pellets. Epub Aug In this study, we reported an approach of combining solubilization agents and precipitation inhibitors to produce a supersaturated drug concentration and to prolong such a drug concentration for an extended period of time for an optimal absorption, thereby improving oral bioavailability of poorly water-soluble drugs.

Solubility of CoQ10 in different surfactant media was measured, and a suitable dissolution medium was developed to compare the dissolution patterns of the solid dispersion, physical mixture, and the pure compound. Epub Nov Chit at a ratio of 3: Pharmazie Apr;56 4: Three different anionic polymers namely Eudragit SEudragit L methacrylic acid copolymersand sodium carboxymethylcellulose NaCMC were used to evaluate the propranolol hydrochloride-anionic polymer interaction.

Epub Jan l1005-5. Click here to view all the property values for this datasheet as they were originally entered into MatWeb. Calculation of the Flory-Huggins interaction parameter based on solubility parameters suggested immiscibility of the two copolymers.

Film formation from aqueous dispersions of micronized HP 55 was affected by the degree of micronization and was improved by reducing the particle size of the polymer. Int J Pharm Feb; To achieve these aims, yield, incorporation efficiency, particle size and the distribution of microspheres were determined, and the influence of the inner phase viscosities prepared with different polymer and polymer mixtures on particle size and the distribution of microspheres were evaluated.

The effects of changing the ratio of HPMC to anionic polymers were examined in water and in media with different pH.
