Title (EN) PROCESSES AND COMPOSITIONS FOR SPRAY DRYING HYDROPHOBIC DRUGS IN ORGANIC SOLVENT SUSPENSIONS OF HYDROPHILIC EXCIPIENTS
(FR) PROCEDES ET COMPOSITIONS DE SECHAGE PAR PULVERISATION DE MEDICAMENTS HYDROPHOBES DANS DES SOLUTIONS DE SOLVANT ORGANIQUE D'EXCIPIENTS HYDROPHILES
Abstract: front page image
(EN)Methods for preparing dry powders having hydrophobic and hydrophilic components comprise combining solutions or suspensions of the components and spray drying them simultaneously in a spray drier. The hydrophobic component may be dissolved in an inorganic solvent and the hydrophilic component suspended therein. The method provides dry powders having relatively uniform characeteristics.
(FR)L'invention concerne des procédés de préparation de poudres anhydres renfermant des composants hydrophobes et hydrophiles. Ces procédés consistent à combiner des solutions ou des suspensions de ces composants et à les sécher simultanément par pulvérisation dans un pulvérisateur. Le composant hydrophobe peut être dissous dans un solvant organique, et le composant hydrophile mis en suspension dans ce solvant. Ce procédé permet d'obtenir des poudres anhydres présentant des caractéristiques relativement uniformes.
