40
Q

Give examples of antiplatelet agents

A

Aspirin, Clopidogrel, Ticagrelor, Prasugrel

41
Q

What do antiplatelet agents do?

A

All prevent new thrombosis

42
Q

When are antiplatelet agents used for?

A
  • angina
  • acute MI
  • CVA/TIA
  • patients at high risk of MI and CVA
43
Q

What are the side effects of antiplatelet agents?

A

Haemorrhage anywhere
Peptic ulcer  haemorrhage
Aspirin sensitivity  Asthma

44
Q

What are anticoagulants used for?

A

Prevent new thrombosis

45
Q

What are anticoagulants used in?

A
  • Deep Vein Thrombosis
  • Pulmonary embolism
  • NSTEMI

  • dabigatran
47
Q

What are side effects of warfarin?

A

Haemorrhage anywhere
Control dose carefully by INR = International Normalised Ratio (measure how thin the blood is when using warfarin)
Reversed by Vitamin K

48
Q

What anticoagulant drugs dont need monitoring?

A

-rivaroxaban and dabigatran. However they aren’t reversible

49
Q

What do fibrinolytic drugs do?

A

dissolve formed clot

50
Q

What are examples of fibrinolytic drugs?

(Hypo or Hyper)

64
Q

What are the two effects of digoxin?

A
  • Blocks atrial-ventricular (AV) conduction

- Increases ventricular irritability which produces ventricular arrhythmias

65
Q

What is the positive effect of digoxin?

A

produces a degree of AV conduction delay

66
Q

What are the negative effects of digoxin?
