Overview of milling techniques for improving the ...

The use of ball milling as a micronization technique for enhancing drug solubility is well supported by literature dating as far back as the 1970s. Apart from its comminution function, ball milling also serves as an intensive mixing technique capable of producing co-ground drug-excipient mixtures comprising amorphous drug forms intimately mixed with suitable hydrophilic excipients at the ...

Improvement in solubility of poor water-soluble drugs by ...

Solid dispersion (SD) has been widely used to improve the dissolution rate, solubility, and oral absorption of poor water-soluble drugs. SD refers to the group of solid products consisting of at least two different components, generally a hydrophilic matrix and a hydrophobic drug; the matrix can be either crystalline or amorphous. Solid dispersion was first introduced to overcome the low ...
