• Thermal preactivation of gaseous precursor filled compositions
  申请人：IMARX PHARMACEUTICAL CORP.

  公开号：EP0901793A1

  公开（公告）日：1999-03-17

  The present invention describes, among other things, the surprising discovery that gaseous precursor filled compositions are profoundly more effective as acoustically active contrast agents when they are thermally preactivated to temperatures at or above the boiling point of the instilled gaseous precursor prior to their in vivo administration to a patient. Further optimization of contrast enhancement is achieved by administering the gaseous precursor filled compositions to a patient as an infusion. Enhanced effectiveness is also achieved for ultrasound mediated targeting and drug delivery.

  本发明描述了，除其他外，令人惊奇的发现，如果在对患者进行体内给药之前，将充满气态前体的组合物进行热预活化，使其温度达到或超过灌注气态前体的沸点，那么这些组合物作为声学活性造影剂的效果就会大大提高。通过向患者输注充满气态前体的组合物，可进一步优化造影剂的增强效果。此外，还能提高超声波介导的靶向和药物输送的效果。
