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… 

An Investigation of Nifedipine Miscibility in Solid Dispersions Using Raman Spectroscopy

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.

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 accelerated

Controlled release of ziprasidone solid dispersion systems from osmotic pump tablets with enhanced bioavailability in the fasted state

The SD-ZIP osmotic pump tablet could be able to enhance the bioavailability in the fasted state and showed sustained release with prolonged actions.


A NIR-chemometric method for direct quantitative determination of diclofenac sodium and two major excipients (matrixforming excipient and diluent) in sustained release, inert matrix type tablets was

In Vitro Comparative Quality Evaluation of Non-Expired and 10 Years-Expired Lamotrigine Immediate-Release Tablet Formulations - Pilot Study

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.

Evaluation of Quality Control Parameters of Expired and Non-Expired Tablets Containing Poorly Water-Soluble Drug (Clopidogrel) with Emphasis on Dissolution Stability

Clopidogrel is an antiplatelet drug available as tablet dosage form (75 mg) alone and in combination with other drugs like aspirin. It is a BCS class II drug that has been reported as sensitive to



Interplay of formulation and process methodology on the extent of nifedipine molecular dispersion in polymers.

Enhancement of the Dissolution and Permeation Rates of Meloxicam by Formation of Its Freeze-dried Solid Dispersions in Polyvinylpyrrolidone K-30

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.

Influence of different polymers on crystallization tendency and dissolution behavior of cilnidipine in solid dispersions

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.

Preparation and Characterization of Solid Dispersion Tablet of Furosemide with Crospovidone

This article investigates enhancement of the dissolution profile of furosemide using solid dispersion (SD) with crospovidone (CPV) by using kneading technique. 1:1 (w/w) and 1:2 (w/w) solid

It is concluded that the preparation of SDs of DCN with PEG provides a promising way to increase its solubility and dissolution rate.

Preparation, Characterization, and In Vitro Evaluation of Nitrendipine Solid Dispersions

In order to enhance the absorption of dissolution rate of nitrendipine (NIT), solid dispersions were prepared using two water soluble carriers, polyvinylpyrrolidone K30 (PVP K30) and polyethylene

In vitro and in vivo evaluation of fenofibrate solid dispersion prepared by hot-melt extrusion

Hot-melt extrusion is an excellent method to improve the dissolution and therefore the bioavailability of fenofibrate and this article compared the difference of Eudragit E100 and polyvinylpyrrolidone-vinyl acetate copolymer S630 in dissolution.
