A

Cocaine

4
Q

Amphetamine derivatives commonly abused

A

Methamphetamine (crystal meth), MDMA (methylenedioxymeth-amphetamine, or ecstasy)

A

PCP (phencyclidine, or angel dust)

6
Q

Synthetic ergot derivative that can produce perceptual hallucinations and used as an illicit drug; may cause paranoia

A

Marijuana

A

Elderly with dementia-related psychosis

9
Q

Antipsychotics that repress primarily the positive symptoms of schizophrenia

A

Typical antipsychotics

10
Q

Primary mechanism of action of typical antipsychotics

Two low potency, typical antipsychotic drugs

A

Chlorpromazine, thioridazine

13
Q

Typical antipsychotic associated with retinopathy and cardiac toxicity

A

Thioridazine

14
Q

Common side effects of low potency typical antipsychotic drugs

A

Dry mouth (anticholinergic), sedation (antihistamine), hypotension (α1 block)

15
Q

Three high potency, typical antipsychotic drugs

A

Haloperidol, fluphenazine, trifluoperazine

16
Q

Typical antipsychotic that can also be used for Tourette syndrome

A

Haloperidol

17
Q

Side effects more commonly associated with high potency typical antipsychotic drugs

A

Dystonia, akathisia, bradykinesia, tardive dyskinesia (extrapyramidal symptoms)

18
Q

Treatment for drug-induced acute extrapyramidal symptoms

A

Benztropine, diphenhydramine

19
Q

Life-threatening side effect associated with typical antipsychotic drugs

A

Neuroleptic malignant syndrome

20
Q

Treatment for drug-induced neuroleptic malignant syndrome

A

Dantrolene

21
Q

Act via BZ1 subtype of GABA receptor, effects reversed by flumazenil

A

Zolpidem (ambien), Zaleplon, eszopiclone

22

Myocardial depression, respiratory depression, N/V, increases cerebral blood flow

A

Inhaled anesthetics

23
Q

Halothane toxicity

A

Hepatotoxicity

24
Q

Methoxyflurane toxicity

A

Nephrotoxicity

25
Q

High potency, high lipid solubility, rapid entry into brain. Used for induction of anesthesia and short surgical procedures

A

Thiopental

26
Q

Most common drug used for endoscopy; used adjunctively with gaseous anesthetics and narcotics

A

Midazolam

27
Q

Used for sedation in ICU, rapid anesthesia induction, and short procedures. Less post-op nausea than thiopental
