Abstract Context: Pharmaceutical solid dispersions are known to be seriously affected by issues of aging and processing. Objective: This study investigated the spectral patterns in the solid dispersions (SD) of Nifedipine/Soluplus/Kollidon SR and the feasibility of the methodology in identification and evaluation of the solid dispersions. Methods: The SD samples were prepared by hot melt extrusion (HMESD), solvent-evaporation (SESD), and fusion-cooling (FCSD). In order to distinguish the… Expand
An Investigation of Nifedipine Miscibility in Solid Dispersions Using Raman Spectroscopy
TLDR
Raman spectroscopy was shown to be a useful technique in classifying miscibility levels based on the hydrophobic interaction between the drug and the polymer and hence variable solid state stability of the solid dispersion. Expand
Release Problems for Nifedipine in the Presence of Soluplus
Nifedipine/soluplus co-precipitates were prepared at 1:9 and 1:1 weight ratios, using the solvent method, with the aim to obtain an improvement of the drug release. The release, though acceleratedExpand
Controlled release of ziprasidone solid dispersion systems from osmotic pump tablets with enhanced bioavailability in the fasted state
TLDR
The SD-ZIP osmotic pump tablet could be able to enhance the bioavailability in the fasted state and showed sustained release with prolonged actions. Expand
QUANTITATIVE CHARACTERIZATION OF SUSTAINED RELEASE TABLETS WITH DICLOFENAC SODIUM BY MEANS OF NEAR-INFRARED SPECTROSCOPY AND CHEMOMETRY

In Vitro Comparative Quality Evaluation of Non-Expired and 10 Years-Expired Lamotrigine Immediate-Release Tablet Formulations - Pilot Study
TLDR
The results of this investigation showed that the drug content did not change significantly, and the lower dissolution rate for expired LTG tablets is due to an interaction of LTG with one or more excipients in the tablet formulation during aging. Expand
Pharmaceutical amorphous solid dispersion: A review of manufacturing strategies
TLDR
This review provides an updated overview of manufacturing techniques for preparing ASDs, and selection strategies are proposed to identify suitable manufacturing methods, which may aid in the development of ASDs with satisfactory physical stability. Expand

TLDR
To explore those supersaturation systems for use in drug delivery of poorly water soluble drugs, it is critical to balance drug-polymer interactions and matrix glass transition point and to consider a process technology with a fast solidification rate during formulation and process development of amorphous SD.

Enhancement of the Dissolution and Permeation Rates of Meloxicam by Formation of Its Freeze-dried Solid Dispersions in Polyvinylpyrrolidone K-30
TLDR
The permeation rate of MX was significantly increased in the case of SDs and was dependent on the ratio of PVP, and the results were primarily due to increase wettability, the solubilization of the drug by the carrier, and formation of MX amorphous form. Expand
Influence of different polymers on crystallization tendency and dissolution behavior of cilnidipine in solid dispersions
TLDR
It implied that the dissolution behavior of CN could bear a close relationship to both hydration capacity and hydrogen-bonding interaction tendency of moieties of the polymers, which might suggest an optimal formulation for CN comprising both PVP and Soluplus. Expand
Evaluation of solid state properties of solid dispersions prepared by hot-melt extrusion and solvent co-precipitation.
TLDR
The solid state properties of solid dispersions of Compound A in hypromellose acetate succinate (HPMC-AS) prepared by hot-melt extrusion (HME) and solvent co-precipitation (CP) processes were evaluated and it was showed that the CP product had a faster dissolution profile, but slower intrinsic dissolution rate than the HME product.
