Title:
超音波媒介デリバリー用ガス充填マイクロカプセル含有医薬組成物
Document Type and Number:
Japanese Patent JP2008538367
Kind Code:
A
Abstract:
Composition comprising gas filled microcapsules and a bioactive agent, useful for an ultrasound-mediated delivery of said bioactive agent. The microcapsules comprise a relatively stiff shell of polymeric or lipid material and have in particular a resistance to a mechanical index of at least 0.15, while the bioactive agent is substantially unbound to the shell of the microcapsules. The composition of the invention is particularly suitable for effectively delivering a genetic material into a cell, upon exposure of the composition to a level of acoustic pressure capable of destroying a portion of the microcapsules and releasing the gas contained therein.
