Modeling and comparison of dissolution profiles.

TLDR
Drug dissolution from solid dosage forms has been described by kinetic models in which the dissolved amount of drug (Q) is a function of the test time, t or Q=f(t).

Surface electrochemistry of mesoporous silicas as a key factor in the design of tailored delivery devices.

TL;DR: It has been found that careful control of surface electrochemistry by functionalization determines the bioactive molecule adsorption whereas the release can be mainly thought of as a diffusion matter dependent on the surface area and molecule size.

Novel starch based nanocarrier for vitamin D fortification of milk: Production and characterization

TL;DR: In this paper, a novel starch based nanoparticles were developed for entrapment of Vitamin D 3, and the physicochemical properties of nanocarriers were characterized by Fourier transform-infrared spectroscopy, X-ray diffraction and differential scanning calorimetry.
Journal ArticleDOI

Citric acid crosslinked β-cyclodextrin/carboxymethylcellulose hydrogel films for controlled delivery of poorly soluble drugs.

TL;DR: The βCD helped to minimize the burst effect and retarded the release of ketoconazole, and the hydrogel films were found to be biocompatible and capable of controlling therelease of ketconazole for long duration.

Nose to brain microemulsion-based drug delivery system of rivastigmine: formulation and ex-vivo characterization

TL;DR: The potential of developed CH-based MME for nose to brain delivery of rivastigmine can only be established after in-vivo and biodistribution study.
Journal ArticleDOI

Solid dispersions of itraconazole and enteric polymers made by ultra-rapid freezing.

TL;DR: Investigation of composition parameters including drug:polymer ratio and polymer type, and particle structure of enteric solid dispersions on the release of ITZ under sink and supersaturated dissolution conditions revealed that miscibility plays an active role in ITZ release under sink conditions, and square root diffusion through the enteric polymer is observed.

The mathematics of diffusion

John Crank
TL;DR: Though it incorporates much new material, this new edition preserves the general character of the book in providing a collection of solutions of the equations of diffusion and describing how these solutions may be obtained.

Introduction to percolation theory

TL;DR: In this paper, a scaling solution for the Bethe lattice is proposed for cluster numbers and a scaling assumption for cluster number scaling assumptions for cluster radius and fractal dimension is proposed.

Mechanisms of solute release from porous hydrophilic polymers

TL;DR: In this article, the role of dynamic swelling and the dissolution of the polymer matrix on the release mechanism was discussed, as well as the effect of the tracer/excipient ratio on the poly(vinyl alcohol) release profile.
Journal ArticleDOI

Mechanism of sustained‐action medication. Theoretical analysis of rate of release of solid drugs dispersed in solid matrices

TL;DR: The analyses suggest that for the latter system the time required to release 50% of the drug would normally be expected to be approximately 10 per cent of that required to dissolve the last trace of the solid drug phase in the center of the pellet.
