The present invention provides a train-like pharmaceutical composition (configuration, or dosage form) comprising segments linearly arranged in series like cars of a train. When the pharmaceutical composition is administrated into a patient's body, some of the segments are “visible” to an instrument, but others are not. However, “invisible” segments can be estimated, deduced, calculated, or inferred from “visible” segments. The “invisible” segments can be used for neutralizing intratumoral lactic acidosis combined with glucose deprivation to control tumor, among other applications.
