Abstract
SE REFIERE A UN PROCESO PARA LA ELABORACION DE UNA COMPOSICION DE ISOTRETINOINA MICRONIZADA DE TAMANO DE PARTICULA DE 5µm A 20µm SUSPENDIDA EN UN VEHICULO OLEOSO QUE COMPRENDE a)DISPERSAR ISOTRETINOINA CON TAMANO DE PATICULA SUPERIOR A 20 µm EN EL VEHICULO OLEOSO PARA FORMAR UNA SUSPENSION QUE CONTIENE 1% A 70% EN PESO DE ISOTRETINOINA; b)SOMETER DICHA SUSPENSION A MEDIOS MECANICOS COMO LA MOLTURACION HUMEDA, HOMOGENIZACION POR ELEVADA CIZALLADURA, MICRONIZACION POR PROPULSION LIQUIDA QUE PRODUCEN CIZALLADURA, IMPACTO, CAVITACION O FRICCION, PARA REDUCIR EL TAMANO DE PARTICULA DE LA ISOTRETINOINA; EL VEHICULO OLEOSO PUEDE SER ACEITE DE SEMILLA DE SOJA, ACEITE DE CACAHUATE, ACEITE DE OLIVA, TRIGLICERIDO DE ACIDO GRASO C6-C18, POLIETILENGLICOL, TRIESTER DE PROPILENGLICOL. LA ISOTRETINOINA SE UTILIZA PARA EL TRATAMIENTO DE ACNE CISTICOIT REFERS TO A PROCESS FOR THE ELABORATION OF A MICRONIZED ISOTRETINOIN COMPOSITION OF A PARTICLE SIZE FROM 5µm TO 20µm SUSPENDED IN AN OILY VEHICLE, INCLUDING a) DISPERSING ISOTRETINOIN WITH A SIZE OF PATICULA OR FORMING IN THE VEHICLE GREATER THAN 20 µm CONTAINS 1% TO 70% BY WEIGHT OF ISOTRETINOIN; b) SUBMIT SUCH SUSPENSION TO MECHANICAL MEANS SUCH AS WET MOLTURATION, HOMOGENIZATION BY HIGH SHEAR, MICRONIZATION BY LIQUID PROPULSION THAT PRODUCE SHEAR, IMPACT, CAVITATION OR FRICTION, TO REDUCE THE ISOLATION OF PARTICULAR SIZE; THE OILY VEHICLE MAY BE SOYBEAN SEED OIL, PEANUT OIL, OLIVE OIL, C6-C18 FATTY ACID TRIGLYCERIDE, POLYETHYLENE GLYCOL, PROPYLENE GLYCOL TRIESTER. ISOTRETINOIN IS USED FOR THE TREATMENT OF CYSTAL ACNE
