Twelve children 1-5 y old were randomly assigned to receive midazolam 0.2 mg.kg-1 either by the intravenous (IV) or intranasal (IN) routes. After IN administration the rapid onset of absorption was observed (t(max) 12 min). After both routes of administration the half-life was similar (2.2 h IN and 2.4 h IV). After IN administration the apparent plasma clearance and volume of distribution were about twice as high as after IV administration. The results are consistent with an estimated mean bioavailability of 55%.
