Mirtazapine is a white to creamy white crystalline powder which is slightly soluble in water. REMERON® is supplied for oral administration as scored film-coated tablets containing 15 or 30 mg of mirtazapine, and unscored film-coated tablets containing 45 mg of mirtazapine. Each tablet also contains corn starch, hydroxypropyl cellulose, magnesium stearate, colloidal silicon dioxide, lactose and other inactive ingredients.
I was able to find information on MAOI's and LSD
here from Erowid, and a little on tricylic antidepressants in
this Lycaeum thread, however the rxlist reference says that its unrelated to these although it is an antidepressant. It doesn't mention being an SSRI, however the file below from MIMS gives specific its pharmacological mechanisms.
I have photographed the
extensive information in MIMS on mirtazapine for anyone who it helps to find out an answer. It is a
732kb file.
