Lofepramine is is a third Generation tricyclic antidepressant which was introduced in 1983 for the treatment of depressive disorders. It is is structurally similar to imipramine which is used here in USA. I do not know if this is available in the USA and have never met anyone that is taking it.
I wish I could help you out a bit more but perhaps another member will have info for you.
Kindly,
Kitt
