SSNRI selective serotonin norepinephrine

The first major groups of antidepressant medications are the tricyclics, also known as the TCAs. Discovered in the late 1950s, these drugs are considered the oldest in the treatment of depression and have historically been used as the first line of medication intervention for the treatment of unipolar depression (Austrian, 1995). The side-effect profile that accompanies this group of medications, however, has recently caused them to fall into disfavor. For years, these medications were often considered the first choice for the client who suffers from depressed mood. Today, however, the antidepressant medications known as the selective serotonin inhibitors (SSRIs), and the selective serotonin norepinephrine inhibitors (SSNRIs) are often considered as the first-line medications. 

Selective serotonin norepinephrine reuptake inhibitors (SSNRIs) The newest group of medicines that have successfully been used to treat emotional and behavioral problems such as depression, panic disorder, obsessive-compulsive disorder (OCD), similar to their counterparts, the SSRIs. Some examples of the SSNRIs include Effexor, Serzone, and Remeron. 

DUAL SELECTIVE SEROTONIN AND NOREPINEPHRINE REUPTAKE INHIBITORS (SSNRIs)... 

Thiophene seems to be very popular in Li Lilly drugs. Its dual selective serotonin and norepinephrine reuptake inhibitor (SSNRI) for depression, duloxetine (Cymbalta), contains a thiophene. And its atypical antipsychotic drug olanzapine (Zyprexa) has a fused thiophene as its core structure.
