Derbisol
From Wikipedia, the free encyclopedia
Derbisol is a fictitious drug used in questionnaires by some academic surveys to test the reliability of answers received by students.
Some such questionnaires ([1] etc) give Derbisol the slang names "DB" and "derbs" and "dirt".
Another common fictitious drug used in questionnaires is shimeron.
This drug information web site (in Korean) seems to use "Derbisol" as a trade name for Clobetasol.
