Dissolution Kinetics of Meloxicam Formulations Co-Milled with Sodium Lauryl Sulfate

open access: yesPharmaceutics, 2022
Meloxicam (MLX) is a poorly soluble drug exhibiting strong hydrophobicity. This combination of properties makes dissolution enhancement by particle size reduction ineffective; therefore, combined formulation approaches are required.

Dissolution Profile of Nimesulide from Pharmaceutical Preparations for Oral Use

open access: yesActa Chimica Slovenica, 2016
Nimesulide belongs to the group of semi-selective COX-2 inhibitors, widely used in solid oral formulations. In the present work the influence of surfactants among other drug excipients, as well as particle size of the active substance and the effects of ...

Surface‐Volume Scaling Controlled by Dissolution Regimes in a Multiphase Flow Environment

open access: yesGeophysical Research Letters, 2023
Fluid‐rock dissolution occurs ubiquitously in geological systems. Surface‐volume scaling is central to predicting overall dissolution rate R involved in modeling dissolution processes.

Albendazole Solid Dispersions: Influence of Dissolution Medium Composition on In Vitro Drug Release [PDF]

open access: yes, 2014
The rate-limiting step to drug absorption is often dissolution from the dosage form, especially for poorly soluble com-pounds. Two possibilities for improving the dissolution of these drugs are to increase the available surface area and to im-prove their

Dynamic reservoir-condition microtomography of reactive transport in complex carbonates: effect of initial pore structure and initial brine pH [PDF]

open access: yes, 2017
We study the impact of brine acidity and initial pore structure on the dynamics of fluid/solid reaction at high Péclet numbers and low Damköhler numbers.

Rate controls on silicate dissolution in cementitious environments

open access: yesRILEM Technical Letters, 2017
The dissolution rate of silicate minerals and glasses in alkaline environments is of importance in cementitious systems due to its influences on: (a) early-age reactivity that affects the rate of strength gain and microstructure formation, and/or, (b ...

Hydrous Manganese Oxide Doped Gel Probe Sampler for Measuring In Situ Reductive Dissolution Rates. 2. Field Deployment [PDF]

open access: yes, 2010
In situ rates of reductive dissolution in submerged shoreline sediments at Lake Tegel (Berlin, Germany) were measured with a novel hydrous manganese (Mn) oxide-doped gel probe sampler in concert with equilibrium gel probe and sequential extraction ...

Dissolution rate and recrystallization of sodium-molybdenum-phosphorus oxide glasses [PDF]

open access: yesE3S Web of Conferences
Phosphate glasses have been able to establish themselves and have received renewed interest from several research teams around the world. The interest shown in our laboratory contributes to the valorisation of Moroccan phosphates and brings added value ...

Diffusion-controlled dissolution of a binary solid into a ternary liquid with partially-molten zone formation [PDF]

open access: yes, 2008
We build a theoretical model of equilibrium dissolution of a homogeneous, solid mixture of two salts A and B, KCl and NaCl being used as the type example, into an aqueous solution of the two salts, with diffusive transport.

Experimental study on the dissolution of supercritical CO2 in PS under different agitators

open access: yese-Polymers, 2021
In the continuous molding of microporous plastics, the polymer/CO2 homogeneous body needs to be formed in a very short time, which affects the subsequent bubble nucleation, bubble pore distribution, and growth, and is the key to the molding.
