That is because you cannot use bind arguments to pass the names of schema objects to a dynamic SQL statement.
Instead, you must embed parameters in the dynamic string, then pass the names of schema objects to those parameters.

-- e.g.
table_name := 'EXAMPLE';
-- dont use: 
stmt := 'DROP TABLE :name CASCADE CONSTRAINTS';
EXECUTE IMMEDIATE stmt USING table_name;

-- instead use:
stmt := 'DROP TABLE ' || table_name || ' CASCADE CONSTRAINTS';
EXECUTE IMMEDIATE stmt;
-- or
EXECUTE IMMEDIATE 'DROP TABLE ' || table_name || 'CASCADE CONSTRAINTS';
