Low-dose Amisulpride Cause Psychosis?

Hi everyone,

In therapeutic doses, amisupride antagonises postsynaptic dopamine D2 and D3 receptors, but in low doses, it enhances dopaminergic neurotransmission by preferentially blocking presynaptic dopamine D2/D3 autoreceptors - does this mean that in low doses, amisulpride could cause psychosis?

My psychiatrist said that she wants to try me on Amisulpride, because they think I’m at risk for schizophrenia. I was going to ask them about the possibility of starting off low and slowly building up over the coming weeks/months, but if I start low, it sounds like things could get worse?

Any input much appreciated :slight_smile:

I see you’ve been reading the text on Wikipedia on Amisulpride - I don’t think anyone here has the necessary degree in neuropsychopharmacology to be able to answer question with any certainty - but one of the questions is what does “low” mean in this situation. I recommend you discuss this issue with your psychiatrist and your pharmacist.

Yeah thanks @SzAdmin. I’ll talk to my doctor next week. It’s just that I’ve been prescribed medication for subjective disorganized thoughts and was getting a little anxious but I’m sure my doctor will be able to clear things up :slight_smile:

@_JDOG26 what I can tell you is that low dose amisulpride( dose range 50-300 mg/day)
is indicated for negative symptoms of schizophrenia.
