1. A process for reconstitution of a solid form of a pharmaceutical composition, comprising the following in succession:
(i) providing the solid form of the pharmaceutical composition in a sealed container, the pressure within the container being an initial pressure comprised between 0.5 Pa and 1.2×105 Pa;
(ii) at a first time point, introducing a solvent into said sealed container and maintaining the resulting pressure pr within the container for a controlled time; and
(iii) at a second time point, before reconstitution is complete, increasing the pressure within the container to a controlled pressure higher than pr until complete reconstitution.
