Abstract
(EN)
The present invention relates to compositions for use in medicine, e.g. as infusion or surgical rinse solutions, and to processes for their preparation. The compositions of the invention comprise an aqueous solution of physiologically inert PVP having a weight average molecular weight in the range of from 3,000 to 14,000 daltons.
(FR)
La présente invention se rapporte à des compositions utilisées en médecine, par exemple en tant que solutions de perfusions ou de bains chirurgicaux, et à des procédés de préparation de telles compositions. Lesdites compositions comportent une solution aqueuse composée de polyvinylpyrrolidone (PVP) physiologiquement inerte ayant un poids moléculaire moyen en poids compris entre 3000 et 14000 daltons.
