8. 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”.
9. Sedative History
• 1870’s—Potassium Bromide
– Anticonvulsant--
– Widely used as sedative—Typical dose: a “few
grams/day” certain hospitals used tons/yr.
10. 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.
11. BROMO

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

apples).
• No direct effect on the central

19. WW II Worried about US troops
being deployed to the
South Pacific, soldiers were
issued barbiturates. The
idea was to lower blood
pressures and respiratory
rates to help soldiers better
cope with the extreme heat
and humidity.
GOOFBALLS
28. 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
29. 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.
31. 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
32. 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,"
46. 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

51. 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
52. 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
53. 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
57. TEMAZEPAM PROFILE
The more rapidly absorbed, the quicker the
access to the brain, the more likely to be abused.

• A 33 year old right handed
male i.v. drug abuser
• Presents three hours after

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.
60. 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

65. 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
66. 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

• 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.

• 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
83. 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.
86. THE ELDERLY

• Over sedation, decreased alertness,

CORONER’S REPORT
93. • 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.

104. 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 )
