Solid dispersions of dihydroartemisinin in polyvinylpyrrolidone

Archives of Pharmacal Research, 2008
In the present study the physicochemical characteristics of dihydroartemisinin, polyvinylpyrrolidone and their solid dispersions were evaluated at various proportions of drug and polyvinylpyrrolidone. These properties were investigated with X-ray diffraction, fourier transform infrared spectrophotometry, differential scanning calorimetry, equilibrium ...

Characteristics of Rofecoxib-Polyethylene Glycol 4000 Solid Dispersions and Tablets Based on Solid Dispersions

Pharmaceutical Development and Technology, 2005
The aim of this work was to report the properties of rofecoxib-PEG 4000 solid dispersions and tablets prepared using rofecoxib solid dispersions. Rofecoxib is a poorly water soluble nonsteroidal anti-inflammatory drug with a poor dissolution profile.

Polymorphism in Solid Dispersions

Crystal Growth & Design, 2019
Solid dispersions embed active pharmaceutical ingredients in polymeric carriers to improve their solubility. Three solid dispersion preparation techniques are typically employed: solvent evaporation, solvent-fusion, and fusion methods. Although these are also widely recommended as preparative methods for phase diagram determination, few examples exist ...

Solid dispersion of ketoprofen in pellets

International Journal of Pharmaceutics, 2000
The formulation of ternary solid dispersions of ketoprofen with Macrogol and kollagen hydrolizate derivative as carriers was elaborated on the basis of the results of the experiments in which different methods of solid dispersion preparation (melting, solvent method, different cooling), different concentrations of drug/carriers and molecular weight of ...

Characterization of nifedipine solid dispersions

International Journal of Pharmaceutics, 2002
The sublingual administration of nifedipine (NIF) is currently used in clinical practice. The sublingual administration of NIF solid dispersions (SD), by using a suitable dispenser, appears an interesting approach in the treatment of moderate and severe hypertensive emergencies.

Evaluation of Solid Dispersions of Clofazimine

Drug Development and Industrial Pharmacy, 2002
Clofazimine (CLF) was formulated with polyethylene glycol (PEG) and polyvinyl pyrrolidone (PVP) as a solid solid dispersion (SSD) to increase the aqueous solubility and dissolution rate of the drug. Different molecular weights of PEG (1500, 4000, 6000, and 9000 Da) and PVP (14,000 and 44,000 Da) were used in different drug:carrier weight ratios (1:1, 1:
