mechanism:
None (4) ·
Competitive antagonist at OX1R and OX2R. Faster receptor association/dissociation kinetics than suvorexant (~16 sec dissociation vs ~57 sec) hypothesized to support sleep onset, with sufficient duration for maintenance. (1) ·
Competitive antagonist at OX1R and OX2R. First-in-class DORA. Receptor dissociation slower than lemborexant or daridorexant. (1) ·
'"`UNIQ--vote-000005D0-QINU`"' Selectivity comes from the viral-kinase-only initial phosphorylation step, which is why uninfected cells generate minimal active drug'"`UNIQ--ref-000005D1-QINU`"'. Dose-adjust by renal function; rare crystalline nephropathy with rapid IV acyclovir. (1)

starting dose:
0.4 mg PO daily (general prevention); 0.8-1 mg/d in pregnancy; 4 mg/d for women with prior NTD-affected pregnancy; 1 mg/d during methotrexate therapy (1) ·
10 mg PO 30 min before bedtime (with ≥7 hours of sleep planned) (1) ·
25 mg PO at bedtime (no titration); may increase to 50 mg if 25 mg inadequate (1) ·
