Question: Show me the name of the medicines that are present in both the tables?
SQL: SELECT T1.name FROM medicine AS T1 JOIN medicine_enzyme_interaction AS T2 ON T2.medicine_id   =   T1.id WHERE interaction_type   =   'inhibitor' INTERSECT SELECT T1.name FROM medicine AS T1 JOIN medicine_enzyme_interaction AS T2 ON T2.medicine_id   =   T1.id WHERE interaction_type   =   'activitor'
