Title
(EN) PRESERVATIVE REMOVAL FROM EYE DROPS
(FR) ÉLIMINATION DE CONSERVATEUR DE GOUTTES OCULAIRES
Abstract
(EN)
A particulate plug for removing a preservative from a solution, suspension, or emulsion comprising a drug is presented. The plug comprises microparticles of oxidized polyolefin (OxPO). The microparticles are irregular-shaped rigid aggregates and are sized and packed to yield a hydraulic permeability greater than 0.01 Da. The OxPO have absorbed portions of a preservative to be removed and/or a drug for delivery in solution, as can the copolymer.
(FR)
L'invention concerne un bouchon particulaire pour éliminer un conservateur d'une solution, d'une suspension ou d'une émulsion comprenant un médicament. Le bouchon comprend des microparticules de polyoléfine oxydée (OxPO). Les microparticules sont des agrégats rigides de forme irrégulière et sont dimensionnées et tassées pour produire une perméabilité hydraulique supérieure à 0,01 Da. Les OxPO ont absorbé des parties d'un conservateur à éliminer et/ou d'un médicament destiné à être administré en solution, tout comme le copolymère.
