Does anyone know if Ludiomil (Maprotiline) is sold in the United States?

I am so excited!  I thought for a long time that Remeron (Mirtazapine - which is what I am currently taking) was the only Tetracyclic that was made.  I have researched for months and have even contacted the manufacturer (Organan) to see if they are in the process of making a Tetracyclic like Remeron, that has worked very well for me.  Then I read on a site that I googled to see if there is a tetracyclic made that is similar to Remeron.  There is once called Ludiomil (Maprotiline). I am not sure how long this drug has been out.  I have researched and have not been able to find out if this drug in sold in the United States where I can get a prescription for it, or talk to the Psychiatrist about it.  Is anyone on this..and do you know if it is sold in the United States? Thanks for any help!
