Morphology

tricyclic + antidepressant

This is a straightforward compositional noun phrase: 'tricyclic' characterizes a chemical feature (tri- = three, cyclic = ring-like) and 'antidepressant' names a drug for depression, so a learner who knows both constituents can infer it denotes a type/class of antidepressant. The expression is not idiomatic or metaphorical and follows regular compounding patterns, making its meaning transparent to learners familiar with the parts.

Etymology

The term tricyclic antidepressant comes from the drug's shape: tri means three and cyclic means 'ring-shaped', because the molecule has three connected rings. So the name simply describes this type of 'antidepressant'.
