The mechanism of action of barbiturates differs
from that of benzodiazepines in that they:
A. Do not affect the GABA-benzodiazepine
receptor-chloride channel complex
B. Act as inverse agonists at the benzodiazepine receptor
C. Increase the frequency of chloride channel
opening without affecting its life time
D. Have both GABA-facilitatory as well as
GABA-mimetic actions
