A device for dosing and dispensing a dose of a non-liquid medicine that comprises a body connectable to a container containing an amount of a non-liquid medicine. When the body is connected with the container, an amount of the non-liquid medicine may be transferred from the container to at least one chamber defined within the body. In a preferred embodiment, two chambers are defined within the body, each having a different predetermined size (i.e., volume). A user may set the amount of the non-liquid medicine to be transferred using a plunger rod slideably located within the at least one chamber, or with each of the two chambers. A kit comprises the device and a non-liquid medicine that is readily dispersible in an aqueous solution suitable for oral administration, preferably a temozolomide formulation that can be titrated readily and accurately.
