Summary
Olanzapine blocks dopamine D2 receptors, directly opposing the dopamine agonist effect of lisuride. This can reduce control of parkinsonian symptoms or other dopaminergic indications, and lisuride may worsen psychosis.
What this interaction means in plain words
Lisuride and Olanzapine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Pharmacodynamic antagonism between D2 receptor blockade by olanzapine and D2 agonism by lisuride.
What to do
Avoid combining where possible; if an antipsychotic is needed in Parkinson's disease, prefer quetiapine or clozapine and monitor motor function and psychosis.
