METOD FOR MIKROINKAPSLING GENOM FASSEPARATION AV VATTENLOSLIGA LEKEMEDELSSUBSTANSER |
摘要 |
The microencapsulation of medicamentous water-soluble substances is carried out by phase separation. The operations of the hardening step take place at a temperature comprised between about 0 DEG and about 25 DEG C., the non-solvent used during this step being an aliphatic fluorinated or fluorohalogenated hydrocarbon or a mixture of such hydrocarbons. Further, the non-solvent is used in an excess with respect to the volume of solvent and non-solvent resulting from the phase-separation step. |
