Sweatman: Sedative Hypnotics Flashcards
(45 cards)
BNZO’s used as anxiolytics
used routinely
ALprazolam Chlordiazepam Clonazepam Clorazepate Diazepam Lorazepam Oxazepam Prazepam
NON-BNZO’s used as anxiolytics
Buspirone
Propranolol
drugs not used routinely because lack durability because of very short half life
would reuire inconvenient dosing regimens
Estazolam Flurazepam Quazepam Temazepam Triazolam
GABA receptor promotes what upon activation
CL influx-hyperpolarization
allosteric agonist
Benzos
benxo MOA
potentiates the effects of GABA (endogenous)-does NOT change efficacy, does increas potency of endogenous GABA
competitive antagonist of gaba receptor
flumazenil-used to emergency situations to alleviate the respiratory depression of benzos
do bnzos activate GABA receptor directly
no but barbs do at high doses
GABA, BNZOS and FLumazenil all act at
GABA receptor at alpha subunit in differnt locations
multimeric chloride channel
barbiturates MOA
increase the efficacy of endogenous GABA by prolnging the binding time of GABA on the receptor
lethal in high doses
BARBITURATES
not lethal in high doses
BENZOES except if used with ETOH
metabolized to nordiazepam-thus these all have a long half life-long duration of clinical effect
clorazepate diazepam chlordiazepoxide prazepam halezepam
B ENZO’s with long duration of clinical effect
clorazepate diazepam chlordiazepoxide prazepam halezepam
benzos with simpler metabolism and thus a short duration of clinical action
Lorazepam
alprazolam
oxazepam
BENZOES THAT DO NOT UNDERG HEPATIC METABOLISM
LORAZEPAM
OXAZEPAM
DRUGS WITH NO POTENTIAL FOR CYP INTERACTIONS
LORAZEPAM
OXAZEPAM
loss of effect or intensitifed effect due to drug drug interactions will not therefore be seen with with benzoes
oxazepam (serax) and lorazepam (ativan)
metaboliszed through UGT glucuronidation
oxazepam and lorazepam
benzos are pregnancy category
d-contraindicated
drugs that work over 48 hours -long
chlordiazepoxide clorazepate diazepam flurazepam prazepam
drugs that work for 10-36 hours-intermediate
alprazolam
lorazepam
temazepam
drugs that work for less than 10 hours-short
clonazepam
oxazepam
triazolam
rapid onset
clorazepate-long
diazepam-long
flurazepam-long
triazolam-intermed
