My depression improved upon the addition of Abilify to my treatment. It was a mild, but unmistakable improvement. I decided to come off of it because my triglycerides were extremely high and I gained a lot of weight. For unipolar depression, my doctor uses 5 mg/day on his patients. He wouldn't continue to use it if he didn't think he was observing positive results. He could be wrong, of course. I guess the question to be asked is how long does such an improvement last? I'm not sure, but I think one needs to consider that Abilify does more than just antagonize D2 receptors. In fact, it is actually a partial agonist at that receptor. Unlike the older antipsychotics, it has a higher affinity at the D3 receptor as an antagonist. It is also a partial agonist at NE alpha-1 receptors, and an antagonist at 5-HT2a receptors.

Is Aripiprazole (and Rexulti) the only one with partial agonism at D2?
