ABSTRACT:
New solid drug dispersions are described in which a drug is present in amorphous form and dispersed within the particles of an organic carrier selected from cross-linked polymers and/or complexing agents. These dispersions are obtainable by mixing the drug and the carrier and applying an oscillating electromagnetic field in the microwave region according to a specific heating cycle wherein the drug-carrier mixture is heated at a temperature higher than the melting point of the drug for at least 5 minutes.
