Title (EN) EXPANDABLE LATTICE OF POLYVINYL ALCOHOL AND POLYETHYLENE GLYCOL
(FR) TREILLIS EXPANSIBLE D'ALCOHOL DE POLYVINYL ET DE GLYCOL DE POLYETHYLENE
Abstract: front page image
(EN)An expandable lattice structure is a film of polyvinyl alcohol and polyethylene glycol having sufficient thickness to retain its structural integrity upon the application of an osmotic pressure and sufficient thinness whereby said expandable lattice structure is capable of sufficient expansion of its lattice structure under the influence of osmotic pressure whereby drug molecules are permitted to pass therethrough.
(FR)Une structure en treillis expansible est constituée par une pellicule d'alcohol de polyvinyl et de glycol de polyéthylène possédant une épaisseur suffisante pour maintenir son intégrité structurale lors de l'application d'une pression osmotique et possédant une minceur suffisante pour permettre à la structure en treillis expansible de se dilater suffisamment sous l'influence de la pression osmotique, permettant aux molécules de médicaments de la traverser.
