OUTLINE
• Terminology
• Pharmacology
• Historical Perspectives
• Intoxication / Withdrawal Syndrome
• Efficacy / Adverse Effects
• Epidemiology
• Case Study
• Withdrawing Benzodiazepines
Terminology
• Sedative
– Induces sedation by reducing agitation/ decreases
CNS excitement in the awake patient
• Hypnotic
– Induces sleep (soporific)
• Anxiolytic
– Decreases anxiety
• Tranquilizer
– Older term
– Minor—anxiolytic
– Major—antipsychotic
Classification of
Sedative-Hypnotic-Anxiolytics
Brain Depressants
– Benzodiazepines: Azopam and Azolam
( Diazepam, Lorazepam, Midazolam, Alprazolam)
• Benzodiazepine-like drugs (zolpidem/zaleplon)
– Carbamates (Glutethiamide, Meprobamate)
– Barbiturates --(secobarbital)
• Barbiturate-Like (Methaqualone )
OPIUM Morphine

MORPHINE
Opioids relieve emotional pain
and this is one of the behavioral
mechanisms implicated in the
addiction cycle
(Khantzian, 1985, 1990, 1997)
1857—BROMIDES AS SEDATIVES
• Women catamenial or
hysteriform epileptic seizures
• Positive outcomes in 14
women out of a sample of 15.
• Bromides were widely
introduced in asylums and
similar institutions throughout
Europe, given their
• sedative and antiepileptic
properties
• It served “to reduce the
expression of the
epileptic patients’ sexuality”.
Sedative History
• 1870’s—Potassium Bromide
– Anticonvulsant--
– Widely used as sedative—Typical dose: a “few
grams/day” certain hospitals used tons/yr.
1897--THE BROMIDE SLEEP
• 2.5 ounces of Sodium Bromide
• A morphine addicted woman, producing a
“bromide brom” of several days from which she
could not be roused.
• When the administration of sodium bromide
ceased, she gradually awakened and reported no
craving for morphine.
• Hypothesis: a 5-9 days Bromide Brom would
produce the same cessation of craving for alcoholics
and also would terminate an acute attack of mania.
• He replicated the treatment in 8 more patients and
achieved the desired results in all but one case. In
this one case, she died of pneumonia.
BROMO
SELTZER
the original formula: 3.2 mEq/teaspoon sodium bromide.
Their sedative effect probably accounted for Bromo-
Seltzer's popularity as a hangover remedy. Early formulas
also used acetanilide as the analgesic, a known
poisonous substance

Nervous ailments: nervous exhaustion,
sleeplessness, hysteria, headache, neuralgia,
backache, pain ,epilepsy, spasms, fits, and St.

BROMISM
Barbituric Acid
• Von Baeyer 1864

BARBITURATE SUICIDE/OVERDOSE
Barbiturate Overdoses
1954
Current uses
of
Barbiturates
BARBITURATES:
DEATH
WITH
DIGNITY
• high doses of barbiturates effective for physician-
assisted suicide
• Opioids are less reliable for physician-assisted death due
to the unpredictable duration of the dying process even
after high doses. The same applies to benzodiazepines.
The most frequent undesired effect is an unexpectedly
long dying process due to impaired uptake of the drugs
ETHINAMATE
• Valmid-- is a short-acting carbamate-
derivative sedative-hypnotic
• Used to treat insomnia.
• Regular use leads to drug tolerance, and it is
usually not effective for more than 7 days.
• Prolonged use can lead to dependency.

1954
Methaqualone--Quaalude
• 1951- synthesized in India as an antimalarial
• 1965 --the most commonly prescribed sedative
in Britain
• 1972 -- the sixth-bestselling sedative in the USA
• JB Roerig & Company division of Pfizer,
discontinued the drug in 1985, mainly due to its
psychological addictiveness and recreational use
Effects can include euphoria, drowsiness, reduced heart rate,
reduced respiration, increased sexual arousal (aphrodisia), and
paresthesias (numbness of the fingers and toes). Larger doses
can bring about respiratory depression, slurred speech,
headache, and photophobia (a symptom of excessive
sensitivity to light).

“MOTHERS LITTLE HELPER”
Mick Jagger
I hear ev'ry mother say
They just don't appreciate that you get tired
They're so hard to satisfy, You can tranquilize your mind
So go running for the shelter of a mother's little helper
And four help you through the night, help to minimize
your plight
Doctor please, some more of these
Outside the door, she took four more
What a drag it is getting old
"Life's just much too hard today,"
ROLLING STONES
I hear ev'ry mother say
The pursuit of happiness just seems a bore
And if you take more of those, you will get an
overdose
No more running for the shelter of a mother's
little helper
They just helped you on your way, through your
busy dying day

PHARMACOKINETICS
BENZODIAZEPINES
• Absorption
– Readily absorbed following oral administration
• Diazepam (Valium) is the most rapidly absorbed,
• BENZODIAZEPINES DIFFER IN :
– Potency—
– Onset of action
– Duration of Action elimination half life.
– BZD metabolites may be active and lengthen the
effect of the parent drug
LIPOPHILIC = LIPID LOVING
ability of a chemical compound to dissolve in fats, oils, lipids, and non-polar solvents such as
hexane or toluene
• BZ are all relatively lipophilic--
• Important in onset & duration of clinical effect
after single dose
• Diazepam & clorazepate highest lipid
Solubility & quickest onsets of action
• After a single dose, BZ will redistribute rapidly
out of CNS to other lipophilic tissues
ELIMINATION
• All BZDs are metabolized by the Liver
– Demethylation Oxidation (P450 3A4)-Valium
– Glucuronide conjugation---Lorazepam, Oxazepam, & Temazepam
– Nitroreduction—Clonazpeam
• With some BZ the metabolites are also active
• All BZ are excreted BY THE KIDNEY

Unrecognized hand ischemia after intraarterial drug injection: successful management of a "near miss" event
Kyros Ipaktchi,corresponding author1 Ramin Ipaktchi,2 Andreas D Niederbichler,2 Peter M Vogt,2 and Karsten Knobloch2
• A 33 year old right handed
male i.v. drug abuser
• Presents three hours after
reportedly self injecting water
dissolved crushed zolpidem
tablets into the right forearm.
His chief complaint was
forearm tenderness extending
down to the hand.
• The patient described an
immediate onset of pain,
which radiated down the arm
into the hand.
18 HOURS AFTER IV AMBIEN
• The right hand was found to be cold and held in a flexed position. There
was absent ulnar artery pulse and only a faint radial artery pulse palpable,
Allen's test was pathological. The hand showed blue discoloration and
there was tenderness over the thenar eminence and hypoesthesia over
the digits 1 through 5 as evidenced by a two point discrimination of
greater than 8 mm
Angiogram: Pre Urokinase
• Angiographic study of right hand showing absent contrast
flow in distal ulnar artery and deep palmar arch, incomplete
filling of superficial palmar arch, hypoperfusion of digits 1
and 2 and no detectable flow in digits 3 to 5
Three months after IV ambien
Within 3 hours after start of thrombolytic
therapy there was a return of normal skin color
to the right hand and restoration of a strong
Doppler detectable ulnar artery and palmar arch
pulse signal. Clinically, the Allen test turned
normal

BZDs and PSYCH PATIENTS
• About 30% of psychiatric patients receive benzodiazepines
• Greatest use in patients with affective disorders, long
• duration of mental illness, and high users of psychiatric
• services
• Generally most patients tend to decrease anxiolytic doses
• over time.
• The use of antidepressants to treat anxiety has increased in
• recent years and the proportion of patients treated with
• anxiolytics has fallen slightly
• There are certain groups of high‐risk patients where longterm
• use, misuse, and abuse are greater than in patients
• with anxiety disorders
BZD USERS
• Most patients take benzodiazepines for periods of <1
• month.
• 12% of the U.S. population used a benzodiazepine for
• medical purposes at least once during a 1‐year period,
• 6 month use occurs in about 3% of the population
• 1% using the medication for a year or longer
• long‐term users are more likely to be older, female,
with more significant chronic health and/or
emotional problems

• OCD /PTSD lowest level of evidence supporting
the use of BZDs.
• Xanax: minimal improvement in overall anxiety
symptoms, with no improvement in the core
symptoms of PTSD
• Interfere with HPA-stress response in animals
with Increased vulnerability to repeat stress
• do not use as mono-therapy; questionable
benefit as an add on.

BZDs & SLEEP
Int J Geriatr Psychiatry. 2011; 26(9):908-15 (ISSN: 1099-1166
• Seniors' Health Survey (ESA) , community-dwelling,
older population in Quebec
• Collège des Médecins du Québec suggests a maximum
length of use of 3 months but the mean length of
benzodiazepine use is longer
• Long-term benzodiazepine users:
– were more likely to report poor sleep quality.
– Sleep quality of initial probable problematic sleepers
tended to increase over 1 year but sleep quality in
benzodiazepines users increased less rapidly than in non-
users.
– Also, women were more likely to report using
benzodiazepines and having poorer sleep quality.
SLEEPING IN THE NURSING HOME
Sleep Med. 2013; 14(7):614-21 (ISSN: 1878-5506)
• 300 residents, 178 (59%) were long-term BZD
users and 122 were nonusers
• Mean age, 85.5 y; range, 57-100; 75% women
• BZD use remained strongly associated with
poor sleep (r=0.173; P=.003)
– difficulties with falling asleep
– more midnight awakenings
– felt less rested in the morning
– poorer self-perceived sleep quality
FOR SLEEP
Findings do not
support long-term
effectiveness of
BZDs
GROUPS AT RISK FOR BZDs
• Alcohol Use Disorders
– Combined Sedation
• Drivers
– Increased RR of MVA 1.5-6.5, depending on dose,
# of BZDs, time of last use, half life.
– Daytime anxiolytics impaired driving performance
irrespective of half-life. Short & Long acting BZDs
taken as hypnotics impaired driving during the 1st
2-4 wks of ingestion.
– Young drivers particularly at risk.
XANAX NOT ALCOHOL
THE ELDERLY
• More sensitive to BZDs effects
• Over sedation, decreased alertness,
confusion: “pseudo-dementia”
• 50% risk of hip fractures: no difference
between short or long-acting medications.
• Multiple Meds with interactions.

• He was discharged 24 hrs. later.
THE PREGNANT
• Rarely cause cleft palate
• Floppy baby syndrome
• Neonatal withdrawal reactions
– Lowest effective dose
– Shortest possible duration
– Avoid in the 1st trimester
– Avoid poly-drug use
– BZDs pass into the breast milk!
Paradoxical Reactions to BZDs
• BZDs have a disinhibitory effect: acute
excitement, increased anxiety, hyperactivity,
aggressive impulses, hostility, rage, assault,
rape.
• Incidence: < 1% to 20%
• High-risk patients: Borderline PDO, Impulse
control Disorder, Chronic alcoholism, Polydrug
users, <18 yrs, >65, learning disabilities
“PROPOFOL a
powerful anesthetic, and the
sedative Lorazepam were the
primary drugs responsible for
Jackson's death. Other
drugs detected in his
system were Midazolam,
Diazepam, Lidocaine and
Ephedrine”.
CORONER’S REPORT
• On the morning Jackson died, Murray tried to induce sleep
without using propofol, according to the affidavit. He said he
gave Jackson valium at 1:30 a.m. When that didn't work, he
said, he injected lorazepam intravenously at 2 a.m. At 3 a.m.,
when Jackson was still awake, Murray administered midazolam.
• Over the next few hours, Murray said he gave Jackson various
drugs. Then at 10:40 a.m., Murray administered 25 milligrams
of propofol after Jackson repeatedly demanded the drug,
according to the court records...
• ... Other drugs that were confiscated in the search included
valium, tamsulosin, lorazepam, temazepam, clonazepam,
trazodone and tizanidine. They also found propofol in Murray's
medical bag. Murray told detectives that he was not the first
doctor to administer the powerful anesthetic to Jackson.

1. Euphoria is rare unless BZDs are used to boost an opiate effect
(combined with methadone)
2. Tolerance to the desired sedative effect leads to escalation in
dose, with withdrawal occurring with dose reduction.
3. BZDs with the highest abuse potential produce a rapid onset of
pleasant mood, well-being, relief of dysphoria, a sense of increased
popularity, the belief that thoughts flow more easily, and a general
state of contentment. (Aprazolam and Valium )

Eur Addict Res. 2011; 17(5):262-70 (ISSN: 1421-9891)
• 12-week prospective, open noncontrolled study
in 282 patients who met DSM-IV-TR criteria for
BZD dependence
• Mean (±SD) pregabalin dose was 315 ± 166
mg/day at the end of the trial.
• significant and clinically relevant improvement
in sleep outcomes at the endpoint, measured by
MOS, with a total score reduction from 55.8 ±
18.9 to 25.1 ± 18.0 at week 12 (i.e. a 55%
reduction).

Highlights of the 2010 Drug Abuse Warning Network (DAWN)
Findings on Drug-Related Emergency Department Visits
DAWN
Drug Abuse Warning Network
• identified an 89% increase in ED visits associated with
benzodiazepines between 2004 and 2008.
• The estimated number of visits for alprazolam in 2008
(104,800) was more than twice the number for the next
most common benzodiazepine, clonazepam (48,400).
• The relative magnitudes of the rates shown generally
reflect prescription volumes.
• 44 million alprazolam prescriptions in 2008.
• New York City Department of Health also showed
benzodiazepines were tied to more than 30 percent of all
the city's overdose deaths in 2009.

In Summary
• In certain anxiety states, alcohol withdrawal, panic
disorder, sleep, the agitated schizophrenic
antipsychotic-induced acute akathisia, BZDs have short
term benefit
• Poor evidence of efficacy in the long-term
• No evidence of relapse prevention
• Well established cognitive side effects
• Addictive Potential
• Significant Withdrawal even with therapeutic dosing
• BZDs can be lethal when combined with alcohol,
opiates, or other sedative/hypnotics.
