Q

How do ACE inhibitors work?

3 steps

A
  1. inhibits enzyme that converts inactive angiotensin I to angiotensin II
  2. less angiotensin II prevents muscles in blood vessel walls contracting, so less vasoconstriction
  3. lowers blood pressure

Q

How do calcium channel blockers work?

5 steps

A
  1. block Ca channels in muscle cells in the artery lining
  2. Ca cannot pass through Ca channels into the muscle cells
  3. stops the muscle contracting
  4. blood vessels cannot constrict
  5. blood pressure is lowered

Q

How do Diuretics work?

4 steps

A
  1. increase the volume of urine the kidneys make
  2. the body can get rid of excess fluids and salts
  3. decrease in blood plasma volume and cardiac output (volume of blood pumped per minute)
  4. lowers blood pressure

Q

How do beta blockers work?

4 steps

A
  1. block the effects of
    the hormone
    adrenaline
  2. reduces heart rate
  3. some preventing production of
    angiotensin II, so stop muscles in blood
    vessel walls contracting/less vasoconstriction
  4. lowers blood pressure

Q

The main type of cholesterol lowering drugs are ________

A

statins

18
Q

Statins work by….

1 point

A
  1. inhibiting an enzyme involved in making LDL cholesterol which lowers LDL cholesterol

NOTE: So statins decrease the risk of heart disease, heart attack and stroke

19
Q

  9. skin inflammation
  10. insomnia
  11. headaches
  12. respiratory problems
  13. depression
20
Q

The 2 types of drugs that prevent blood clots are called?

A
  1. Platelet inhibitory drugs

2. Anticoagulants

21
Q

How does Aspirin (platelet inhibitory drug) work?

1 step

A
  1. Aspirin reduces the ‘stickiness’ of platelets and reduces clots
22
Q

What is Clopidogrel? (1 point)

A
  1. alternative platelet inhibitory drug, can be used combined with aspirin
23
Q

Risks of {Aspirin/Aspirin+clopidogrel}? (1 risk)

A
  1. gastrointestinal bleeding
24
Q

Name an Anticoagulant

A

Warfarin

25
Q

What does Warfarin do? (1 point)

A
  1. blocks the synthesis of clotting factors
26
Q

Risks of Warfarin? (1 risk)

A
  1. risk of bleeding
27
Q

Benefits of statins?

2 benefits

A
  1. Decreases risk of heart disease, heart attack and stroke
    (in patients with CVD reduces heart attack by 33%)
  2. Reduce blood cholesterol, which reduces therosclerosis
28
Q

Define side effect (1 point)
