"The US Food and Drug Administration (FDA) has approved pimavanserin tablets (Nuplazid, Acadia Pharmaceuticals) for the treatment of hallucinations and delusions associated with psychosis in Parkinson's disease (PD).
Isolated instances of mental confusion, euphoria, agitation and disturbed behavior have been reported in susceptible patients. Also, the central anticholinergic syndrome can occur as an adverse reaction to properly prescribed anticholinergic medication, although it is more frequently due to overdosage. It may also result from concomitant administration of an anticholinergic agent and a drug that has secondary anticholinergic actions (see PRECAUTIONS - DRUG INTERACTIONS and OVERDOSAGE sections). Caution should be observed in patients with manifest glaucoma, though no prohibitive rise in intraocular pressure has been noted following either oral or parenteral administration. Patients with prostatism, epilepsy or cardiac arrhythmia should be given this drug with caution.
Occasionally, drowsiness may occur, and patients who drive a car or operate any other potentially dangerous machinery should be warned of this possibility. As with other drugs action on the central nervous system, the consumption of alcohol should be avoided during AKINETON (biperiden) therapy.
