Subsequent IV administration, the onset of action ranges from almost immediately for pentobarbital sodium to 5 minutes for phenobarbital sodium. Maximal CNS melancholy may not occur until quarter-hour or even more following IV administration for phenobarbital sodium. Duration of action, which is connected to the speed at which the barbiturates are redistributed through the body, varies among individuals and in a similar individual every so often.
