ABSTRACT
To improve the in vitro dissolution and in vivo absorption as well as the bioavailability after oral administration by increasing the solubility with the formation of solid dispersion remains a great challenge for the oral dosage form design of poorly water-soluble drugs. Compared with the other pharmaceutical techniques in improving the solubility for poorly water-soluble drugs, priorities are usually given to solid dispersion for its manufacturing convenience. Following the characteristics introduction, we were focused this review on the novel carriers and advanced techniques used for preparing solid dispersions. Amphiphilic polymers used as novel solid dispersion carriers are Solutol HS 15, Soluplus and poly [MPC-co-BMA]. Inorganic materials like magnesium aluminum metasilicat, mesoporous silica microparticle and mesoporous magnesium carbonate are introduced together with the advanced solid dispersing techniques such as supercritical fluid technology, high speed electro-spinning and microenvironmental pH modified technology.
