Abstract
A multiple chamber flexible pharmaceutical bag includes a front film and a back film joined to the front film around a perimeter of the pharmaceutical bag to define a first chamber holding a lyophilized pharmaceutical product and a second chamber holding a reconstituting solution for reconstituting the lyophilized pharmaceutical product held in the first chamber. The pharmaceutical bag includes a seal disposed between the first chamber and the second chamber and defining a connection between the front film of the pharmaceutical bag and the back film of the pharmaceutical bag. The seal breaks when a predetermined amount of force is applied to the pharmaceutical bag such that the connection between the front surface and the back surface of the pharmaceutical bag is torn apart to fluidly connect the second chamber to the first chamber. The front film, the back film, and the seal are comprised of the same material.
