Data Changes
This release includes a new term type (TTY), MIN. This TTY indicates a collection of base ingredients (i.e. the moiety without the salt). The concepts with MIN TTYs have relationships to the IN and SCD TTYs. In a small number of instances where an SCD contains two salt or isomer forms of the same ingredient (e.g. many of the SCDs associated with the BN 'Adderall'), the MIN name contains precise ingredients. In addition, such a concept with the MIN TTY includes relationships to the PIN and SCD (and possibly also IN) TTYs.
