Antagonism at receptors other than dopamine and serotonin with similar or greater affinities may explain some of the other effects of quetiapine and norquetiapine: antagonism at histamine H 1 receptors may explain the somnolence, antagonism at adrenergic α 1b receptors may explain the orthostatic hypotension, and antagonism at muscarinic M 1 receptors may explain the anticholinergic effects.
The management of NMS should include: 1 immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy; 2 intensive symptomatic treatment and medical monitoring; and 3 treatment of any concomitant serious medical problems for which specific treatments are available.
