Midodrine is a prodrug which forms the active metabolite, desglymidodrine, which is an α 1-adrenergic receptor agonist and exerts its actions via activation of α 1-adrenergic receptors of the arteriolar and venous vasculature, producing an increase in vascular tone and elevation of blood pressure.
Flunarizine is a selective calcium antagonist with moderate other actions including antihistamine, serotonin receptor blocking and dopamine D 2 blocking activity. Compared to other calcium channel blockers such as dihydropyridine derivatives, verapamil and diltiazem, flunarizine has low affinity to voltage-dependent calcium channels.

Less common side effects include sleep paralysis (1.3% at 5 mg and 1.6% at 10 mg vs. 0% for placebo) and hypnagogic hallucinations (0.1% at 5 mg and 0.7% at 10 mg vs. 0% for placebo). [ 3 ] Lemborexant at doses of 10, 20, and 30 mg produces drug-liking responses similar to those of zolpidem (30 mg) and suvorexant (40 mg) in recreational ...
