Pimavanserin ve Zaleplon etkileşimi

Post-marketing reports have shown that complex sleep behaviors may occur with zaleplon alone at recommended dosages, with or without the concomitant use of alcohol or other central nervous system (CNS) depressants.

Coadministration with other CNS depressants (e.g., benzodiazepines, opioids, tricyclic antidepressants, alcohol) increases the risk of CNS depression.

Dosage adjustments of zaleplon and of other concomitant CNS depressants may be necessary when zaleplon is administered with such agents because of the potentially additive effects.

The risk of next-day psychomotor impairment, including impaired driving, is increased if zaleplon is taken with less than a full night of sleep remaining (7 to 8 hours); if a higher than the recommended dose is taken; if coadministered with other CNS depressants or alcohol; or if coadministered with other drugs that increase the blood levels of zaleplon.

Some of these changes may be characterized by decreased inhibition (e.g., aggressiveness and extroversion that seem out of character), similar to effects produced by alcohol and other CNS depressants.
