Intravenous lipid emulsions are used for total parenteral nutrition and as carriers for lipophilic drugs. Exposure to the high temperature (121 degrees C) required for steam sterilization may cause coalescence and an increase in droplet size. The pur

The objective of this work was to assess the effect of two formulation variables, hydroxypropylmethylcellulose (HPMC)/lactose ratio and HPMC viscosity grade, on the release of a model drug and HPMC, as well as the mechanism of drug release from HPMC-

Two scaling laws for predicting polymer and drug release profiles from hydrophilic matrices were developed. They were developed on the basis of the diffusion layer and the polymer disentanglement concentration, rho p,dis, the critical polymer concent

A semiempirical formula was developed for the diffusion coefficient, Dp, of polymer within the diffusion layer adjacent to a matrix undergoing swelling and dissolution. This formula of Dp was a key element in a comprehensive mathematical model that d

A comprehensive model is developed to describe the swelling/dissolution behaviors and drug release from hydrophilic matrices. The major thrust of this model is to employ an important physical property of the polymer, the polymer disentanglement conce
