| 毒性 | A barbiturate that causes CNS depression, apparently due to a facilitation of GABA-ergic inhibition. It appears that the site of action of pentobarbital may be the macromolecular complex made up of a GABA receptor, chloride channel, benzodiazepine-binding site, and picrotoxin-binding site. Barbiturates have been shown to compete for dihydropicrotoxinin-binding sites. In clinical use, barbiturates such as pentobarbital have been largely replaced as sedative-hypnotics by the much safer benzodiazepines. The sedative-hypnotic properties of barbiturates may lead to abuse, as tolerance and dependence are known to occur. In animals, pentobarbital is routinely used for its anesthetic and anticonvulsant properties, as well as for euthanasia. Pentobarbital, like other barbiturates, can induce the metabolism of other compounds by altering cytochrome P450 activity. The oral LD50 in rats is 118 mg/kg. |
