I've never heard of any antidepressants that actually target dopamine - I believe they only target serotonin, norepinephrine, or both. The only reason dopamine is involved is because of the biochemistry that goes on in your brain... its believed that serotonin actually "hijacks" dopamine transporters, and the more serotonin you have in your brain's pathways, the more this takes place. Serotonin has always been looked at at kind of the "moderator" of all other neurotransmitters, and its interaction with dopamine in people who take SSRI's is just an example of that. Its a slow process though, which is theorized to explain why it takes weeks for any anti-anxiety effects to be seen.
So basically, if you are taking a med for your anxiety, you ARE getting a med that will alter the levels of serotonin. All SSRI's, MAOI's and TCA's (the most common forms of antidepressants) do this.
Hope I helped! I was a biopsychology major in college :)
