autonomic nervous system

Question 1

therapeutic action Adrenaline

Answer 1

emergency treatment anaphylactic shock

Question 2

mechanism of action Adrenaline

Answer 2

both alpha- and beta-receptors are activated by adrenaline, but the main functions are the beta-receptors of the bronchi, blood vessels, heart and smooth muscle.

Question 3

adverse effects Adrenaline

Answer 3

hyperactivity
arrhytmias
insomnia

Question 4

contraindications Adrenaline

Answer 4

hypoxia (body is deprived of oxygen supply at the tissue level)

Question 5

drug interaction Adrenaline

Answer 5

atherosclerosis

Question 6

therapeutic action a1-selective antagonist (prazosin)

Answer 6

hypertension

Question 7

mechanism of action a1-selective antagonist (prazosin)

Answer 7

selective barrier

decreased peripheral vascular resistance is caused by a selective barrier of post-synaptic a1-receptors, caused by impairment of vasoconstriction set in motion by catecholamine.
This causes a slight increase in heart rate

Question 8

adverse effects a1-selective antagonist (prazosin)

Answer 8

dizziness
headache
fatigue

Question 9

contraindications a1-selective antagonist (prazosin)

Answer 9

renal disease

liver disease

Question 10

drug interaction a1-selective antagonist (prazosin)

Answer 10

beta-blockers

Question 11

therapeutic action beta-blockers (propranolol)

Answer 11

hypertension

Question 12

mechanism of action beta-blockers (propranolol)

Answer 12

catecholamine actions are competitively blocked due to the impairment of B-receptors.
It has both metabolic and cardiac effects

Question 13

adverse effects beta-blockers (propranolol)

Answer 13

insomnia
fatigue
nightmares

Question 14

contraindications beta-blockers (propranolol)

Answer 14

asthma

bradycardia

Question 15

drug interaction beta-blockers (propranolol)

Answer 15

antacids
