BACKGROUND OF THE INVENTION 0009 Amoxapine is a tricyclic antidepressant (TCA). 0002 The invention relates to the treatment of inflam Based on the ability of amoxapine to act in concert with matory disorders. prednisolone to inhibit TNFC. levels, one skilled in the art will recognize that other TCAS can also be used in the 0003) Inflammation occurs when tissues are injured by present invention. Structural analogs of amoxapine that are Viruses, bacteria, trauma, chemicals, heat, cold or any other not tricyclic antidepressants can also be used. Exemplary harmful Stimulus.
