Construct validity is concerned with whether the test measures the concept that it's intended to measure. In this case, since the drug works but not for the reasons proposed in the hypothesis, it suggests an issue with how the theoretical concept (the reason the drug is supposed to work) is operationalized or measured, indicating a problem with construct validity.
