Abstract
After intranasal administration of metoclopramide, (5 mg in 0.5 ml sterile water) the maximum plasma concentration of 13.5 +/- 7.3 (mean +/- s.d.) ng ml-1 was achieved. Absolute bioavailability was 50.5 +/- 29.5%, 110 +/- 41 min later. We conclude that the intranasal route does not allow rapid absorption of the drug and is not associated with greater bioavailability than the oral route.
