Doripenem is also solution in N,N-dimethylformamide. Doripenem's chemical configuration has 6 asymmetrical carbon atoms (6 stereocentres) and is most commonly supplied as one pure isomer. In terms of doripenem for injection, the crystallized powered drug can form a monohydrate when mixed with water. However, Doripenem has not been proven to possess polymorphism.
