“…The best evidence for drugs causing TEN is accumulated clinical experience, certain drugs recurring as suspects, until suspicion becomes probability, and probability approaches certainty (Rostenberg et al, 1968;B6ttiger, 1975).

There were 92 suspected drugs in the list prepared by Bandmann (1970).…”
