Substitute injectable tactics that demonstrate prospective include things like retroorbital and intrahepatic injection. In mice, retroorbital injection of an overdose of ketamine and xylazine resulted in quick Demise (cessation of heartbeat developing in about five s), because the pharmacokinetics of retroorbital injection carefully resemble All those of intravenous injection.

Maximal CNS depression may not occur until quarter-hour or maybe more immediately after IV administration for phenobarbital sodium. Length of action, which can be linked to the speed at which the barbiturates are redistributed all through the entire body, varies amid people As well as in the same particular person from time to time. No reports have shown that the different routes of administration are equal with respect to bioavailability. Barbiturates are weak acids which might be absorbed and speedily distributed to all tissues and fluids with high concentrations during the brain, liver, and kidneys.

The more lipid soluble the barbiturate, the more speedily it penetrates all tissues of your body.
