Interação entre Guanfacina e Suvorexanto

Consider the potential for additive sedative effects with CNS depressant drugs.

Before using INTUNIV with other centrally active depressants, consider the potential for additive sedative effects.

…Interactions: Effect of other Drugs on INTUNIV Concomitant Drug Name or Drug Class Clinical Rationale and Magnitude of Drug Interaction Clinical Recommendation Strong and moderate CYP3A4 inhibitors, e.g., ketoconazole, fluconazole Guanfacine is primarily metabolized by CYP3A4 and its plasma concentrations can be significantly affected resulting in an increase…

Decrease INTUNIV to 50% of target dosage when coadministered with strong and moderate CYP3A4 inhibitors ( 2.7 ).

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

The risk of next-day impairment, including impaired driving, is increased if BELSOMRA is taken with less than a full night of sleep remaining, if a higher than the recommended dose is taken, if co-administered with other CNS depressants, or if co-administered with other drugs that increase blood levels of BELSOMRA.

Complex sleep behaviors may occur following the first or any subsequent use of BELSOMRA, with or without the concomitant use of alcohol and other CNS depressants [see Drug Interactions (7.1) ] .
