Abstract
A method comprising the following steps: preparing in a vacuum a dry form ( ) of an active principle, as well as a liquid ( ), and drawing this liquid into the dry form, by the action of the vacuum to obtain an injectable preparation. The device comprises a gastight syringe ( ) to condition under vacuum the dry form, a reservoir ( ) containing the liquid ( ) and a cap ( ) forming a connector between the syringe and the liquid reservoir, the injection needle ( ) of the syringe being driven into the septum ( ) of the cap ( ). The invention enables a preparation which is directly injectable by an automatic rehydration step to be obtained; indeed, after activation, the extemporaneous preparation is automatic since the device elements move by themselves under the action of the liquid which is drawn by suction into the volume under vacuum containing the solid formulation ( ).
