Q

What happens as someone continues to absorb nicotine?

57
Q

Hepatocellular injury.

Also, if someone goes back on opioids while on naltrexone, they might OD by accident because naltrexone is an antagonist.

58
Q

What agonist treatment is indicated for chronic opioid use?

A

Methadone!

Helps decrease withdrawal s/s and blocks the high from acute use.

59
Q

Why might patients accidentally OD while on methadone?

A

Methadone has a slow onset, so patients might get impatient waiting for it to take effect or think its not working.

60
Q

How does one qualify for methadone tx?

Must meet at least 1 of 4 criteria:
1+ yr of opioid use.
Hx of methadone maintenance and showing signs of imminent return to dependence.
Recently released from hospital/prison with hx of dependence.
Pregnant and opioid dependent.

61
Q

What agonist discourages abuse?

A

Buprenorphine + naloxone (Suboxone)

62
Q

How is suboxone given?

63
Q

What are the non-pharmacological treatment options for opioid use?

A

CBT
Insight oriented therapy
Resident programs
Peer support groups

64
Q

What do psychostimulants do?

A

Cause a release and block the reuptake of Dopamine, NE, and serotonin.

65
Q

What are the psychostimulants (legal and illegal)?

A

Meth
MDMA (Ecstasy)

66
Q

Where do psychostimulants tend to accumulate?

67
Q

What are the two most common ways psychostimulants are taken?

A

Smoking
Snorting

68
Q

What is a key difference between acute amphetamine intoxication vs opioid?

A

DILATED pupils in amphetamines.

PINPOINT pupils in opioids.

69
Q

How do we treat amphetamine intoxication?

A

Symptomatic treatment.

Sedation/seizure control via IV Benzos (Haldol)
Airway management
AntiHTNs
Hyperthermia (cooling blankets, ice packs, NO ANTIPYRETICS)
Fluids

70
Q

Why are antipyretics not indicated in amphetamine treatment protocols?

A

The hyperthermia is due to muscle ridigity, not fever.

71
Q

What can amphetamines have cross-sensitivity with?

A

Cocaine

72
Q

How does long term amphetamine use cause motor and cognitive deficits?

A

Decreased dopamine receptors in the basal ganglia lead to motor deficits.
Decreased metabolic rate in the prefrontal cortex leads to cognitive deficits.

73
Q

Whats the main drug class we use for anyone in amphetamine withdrawal?

A

Benzos.

There is no general proven med treatment regimen.

74
Q

What are the pharmacologic options for treating chronic amphetamine use?

A

Bupropion + naltrexone (First-line)

Mirtazapine (2nd line)
Adjuncts/alts: Methylphenidate (stimulant), topamax (Anticonvulsant)

75
Q

What is the MC abused anxiolytic?

A

Benzos

76
Q

What is the MOA of benzos?

A

Enhancing the effect of GABA (Inhibitory NT)

77
Q

When are benzos indicated?

A

Sedation
Sleep-induction
Anticonvulsant
Anxiolytic
Muscle relaxant
Alcohol withdrawal

78
Q

What does chronic benzo use do?

A

Changes GABA receptor structure, leading to decreased affinity.

79
Q

What will just a benzo OD present as?

A

CNS depression with normal vitals.

80
Q

How do benzo ODs usually present in real life?

A

With alcohol as well, leading to CNS depression AND respiratory depression.

81
Q

What is the treatment protocol for anxiolytic OD?

A

Airway
Breathing
Circulation

82
Q

What medication is used to treat anxiolytic OD?

A

Flumazenil (controversial competitive antagonist of GABA receptors)

83
Q

How is anxiolytic withdrawal treated?

A

Long-acting Benzos. (best for overall treatment)

Withdrawal from chronic benzo use can be very dangerous, so treatment requires precision.
