How Norpethidine connects Entity context

The extracted context around Norpethidine shows recurring relationship patterns in the source. For example, Norpethidine → AU: Unscheduled, BR: Class A1 (Narcotic drugs), CA: Schedule I, DE: Anlage II (Authorized trade only, not prescriptible), UN: Narcotic Schedule I, US: Schedule II Another extracted example is Norpethidine → controlled drug because of its potential uses in manufacturing both pethidine itself and a range of N-substituted derivatives, major complication when pethidine is used in medicine as an analgesic. Use these groups to spot repeated connection types before inspecting the individual relationships.
