This review aimed to find information about the solubility of the fenofibrate solid dispersion system using PEG 6000. Fenofibrate is an antihyperlipidemic drug that belongs to the Biopharmaceutical Classification System Class II (BCS II) with low solubility. To find information was by conducting a literature search in national and international journals in the last ten years (2010-2020) through websites, namely Google Scholar, Science Direct, NCBI, ResearchGate, and other trusted journals. Several keywords were used as follows: fenofibrate, solid dispersion, PEG 6000, and dissolution rate. The results of several research journals showed that the solid dispersion of fenofibrate using PEG 6000 made by various methods causes a reduction in particle size to increase the solubility and dissolution rate of fenofibrate. The solid dispersions system was made using several methods, namely fusion (melting), solvent evaporation, dropping, and co-grinding, which is a technique used to increase the solubility of a drug. PEG 6000 was chosen as the carrier because it has high hydrophilicity, is non-toxic, inert, economical, has a low melting point, and is dense at melting temperature to withstand crystallization. Thus it can be concluded that the manufacture of solid dispersion of fenofibrate using PEG 6000 and several methods showed the same results, namely an increase in solubility and dissolution rate.

The aim of the present study was to improve the solubility and dissolution rate of a poorly water-soluble drug by a solid dispersion technique, in order to investigate the effect of these polymers on release mechanism from solid dispersions. Diazepam was used as a model drug to evaluate its release characteristics from different matrices. Solid dispersions were prepared by using polyethylene glycol 6000 (PEG-6000), HPMC, HPC and Poloxamer in different drug-to-carrier ratios (1:2, 1:4, 1:6, 1:8, 1:10). The solid dispersions were prepared by solvent method. The pure drug and solid dispersions were characterized by in vitro dissolution study. Distilled water was used as dissolution media, 1000 ml of distilled water was used as dissolution medium in each dissolution basket at a temperature of 37°C and a paddle speed of 100 rpm. The very slow dissolution rate was observed for pure Diazepam and the dispersion of the drug in the polymers considerably enhanced the dissolution rate. This can be attributed to improved wettability and dispersibility, as well as decrease of the crystalline and increase of the amorphous fraction of the drug. SEM (Scanning Electron microscope) studies shows that the solid dispersion having a uniform dispersion. Solid dispersions prepared with PEG-6000, Poloxamer showed the highest improvement in wettability and dissolution rate of Diazepam. Solid dispersion containing polymer prepared with solvent method showed significant improvement in the release profile as compared to pure drug, Diazepam.DOI: http://dx.doi.org/10.3329/icpj.v1i12.12453 International Current Pharmaceutical Journal 2012, 1(12): 423-430

Ketoprofen is included in the Class II of Biopharmaceutical Classification System (BCS) which has low solubility. Low solubility will affect the dissolution rate and the dissolved concentration, so the absorption and bioavailability are low as well. Several studies have been conducted to improve the solubility and the dissolution of drugs from these group, such as by solid dispersion system. This study aims to determine the effect of polyvinyl alcohol (PVA) on the dissolved concentration of ketoprofen in solid dispersion and in physical mixture, and to decidethe optimum formula.Solid dispersion and physical mixture of ketoprofen - PVA were formulated with the ratio of 1:1, 1:2 and 1:4, and then compared with the standard ketoprofen. Evaluation of solid dispersion was performed by the intervention test of PVA as a matrix on the maximum wavelength of standard ketoprofen using a UV-Vis spectrophotometer and the dissolution test in artificial gastric fluid media without pepsin using a basket stirrer at pH ± 1,2, the temperature of 37 ± 0.5ºC, and device speed of 50 rpm. The sample was collected at 10, 20, 30, 45, and 60 minutes. The amount of dissolved ketoprofen was determined by a UV-Vis spectrophotometer at a wavelength of 260 nm. The results showed that there was no shifting on maximum wavelength point in both solid dispersions and physical mixtures. The dissolved ketoprofen concentration that was represented in solid dispersion was greater than in physical mixture and standard ketoprofen. The highest dissolved ketoprofen concentration was indicated in solid dispersion formula with the ratio of 1:1.

In order to investigate the effect of polymers on release mechanism of poorly soluble drugs from solid dispersions, Clonazepam was used as a model drug for these purposes. Five types of solid dispersions were prepared using polyethylene glycol 6000 (PEG- 6000), Kollicoat IR, Kollidon VA 64 and Poloxomer in different drug-tocarrier ratios (1:2, 1:4, 1:6, 1:8, 1:10). The solvent evaporation method was used for preparation of solid dispersions. The in-vitro dissolution study with temperature of 37° C and a paddle method, 100 rpm was used in 1000 ml of distilled water as dissolution medium in each dissolution basket for the pure drug and solid dispersions. For pure Clonazepam showed very slow dissolution rate and the solid dispersion considerably enhanced the dissolution rate. Decreased crystalline and increased amorphous fraction of the drug was probably done by wettability and dispersibility. The highest improvement in wettability and dissolution rate of Clonazepam was observed in PEG-6000, Poloxomer and Kollidon VA 64 (1:10 ratio). Solid dispersions containing polymer (1:10 ratio) prepared by solvent method showed significant improvement in the release profile as compared to pure drug, Clonazepam.

Repaglinide is a pharmaceutical drug used for the treatment of type II diabetes mellitus, it is characterized with poor solubility which limits its absorption and dissolution rate and delays onset of action. In the present study, immediate release solid dispersion of repaglinide was formulated by solvent evaporation technique. Repaglinide solid dispersions were prepared using PEG 8000, Pluronic F 127 and Gelucire 44/14 by solvent evaporation method. A 3-factor, 3-level central composite design employed to study the effect of each independent variable on dependent variables. FTIR studies revealed that no drug excipient interaction takes place. From powder X-ray diffraction (p-XRD) and by scanning electron microscopy (SEM) studies it was evident that polymorphic form of repaglinide has been converted into an amorphous form from crystalline within the solid dispersion formulation. The correlation coefficient showed that the release profile followed Higuchi model anomalous behavior and hence release mechanism was indicative of diffusion. The obtained results suggested that developed solid dispersion by solvent evaporation method might be an efficacious approach for enhancing the solubility and dissolution rate of repaglinide.
