Cards

Term
What pathway in the brain is important in reward pathway?
Definition
DA release in nuc accumbens, innervated from Ventral Tegmental Area.
Term
What does ALDH do?
Definition

Converts acetaldeyde to acetic acid.

If too much acetaldehyde builds up --> sweating, flushing, HA.

Term
What happens acutly with Morphine?
Definition
decreased cAMP levels in nn
Term

What happens when Morphine doesn't surpress cAMP?

What happens when you remove morphine?

Definition

Tolerance.

Increase leveles of cAMP (withdrawal)

Term
Is it likely that a pt can go from substance dependance to non-problem use?
Definition
NO
Term
What does Cocaine do?
Definition

Blocks DA reuptake --> euphoria

at high levels , blocks V gated Ca channels --> no pain

Blocks uptake of NE (minimize bleeding).

Term
What are the consequences of cocaine use?
Definition

Tremors, seizures, convulsions.

Resp.depression.

Cardiovascular: atherosclerosis

Term
ETOH MOA
Definition

GABAa receptor activity

increased or more rapid metabolism of Rx

Term
SE of EtOH
Definition

Enzyme induction

Diuresis: dec in ADH

Resp Depression: GABA mediated hyperpolarization of nn in resp center.

CV: dec contractilibility, vasodilation

Esophagitis, GI bleeding

Cirrhosis of liver: depletion of NAD+ in liver, liver cant metabolize FFAs --> fatty buildup, acetylaldehyde build up

Teratogenic: Fetal Alcohol Syndrome (FAS)

Wernike-korsokaof

Term
What Rx can you use for Rx?
Definition

Naltreoxne

Acamprosate

Disulfram

 

Compliance is a challenge.

Term

Definition

CB1: mediate psychoactive properties

CB2: involved in nausea

Term
Whats a predictive risk factor of drug abuse?
Definition
Age which they start using.
Term

Definition

Rx marijuana

 antiemetic

appetite stimulation

Term
What do amphetamines do?
Definition

speed, uppers.

Stimulants.

Increase wakefullness: military pilots.

ADHD

Anorexia

Narcolepsy

Term
What is the MOA of Amphatamines?
Definition

Increase NE/DA release

Block NE/DA uptake

Stimulates NE/DA Receptors

Inhibit MOA

 

Basically increase NE and DA.

Term
 Amphatamines abuse causes what?
Definition

CVA -HTN

Hyperpyrexia: increase temp --> convulsions, coma

induced phychosis
