Q

Calcium channel blockers x3 examples?

A

Amlodipine, diltiazem, nifedipine (verapamil)

17
Q

x3 calcium channel blocker side effects?

A

Flushing, headache, bradycardia

18
Q

Lidocaine used for?

A

Ventricular tachycardias

19
Q

Lidocaine mechanism of action?

A

Blocks inactivation gate of the sodium channel

20
Q

Amlodipine v verapamil why is verapamil more effective anti-arrhythmic agent?

A

Lack of effect on the calcium channel at rest

21
Q

Propranolol as a beta blocker why good after a heart attack in controlling arrhythmias?

A

Sodium channel blocker (is a beta-adrenoceptor blocker)

22
Q

ACEi will reduce circulating level of which hormone?

A

Aldosterone

23
Q

Why are beta blockers effective in chronic heart failure?

A

Block reflex SYMPA responses which stress failing heart

24
Q

Tolerance is a potential SE for which drug?

25
MI immediate medication?
MONA - morphine, nitrates, oxygen, aspirin (or clopidogrel)
26
Nitrates are?
Vasodilatory
27
Beta blockers have what effect on heart?
Prolong filling so HR control (slow down), reduce myocardial contractility
28
Atenolol acts on which peripheral receptor?
Beta-1 adrenoceptor
29
Glyceryl trinitrate relieve pain of angina pectoris?
Dilation of vein to reduce preload on heart
30
Calcium channel blockers mechanism of action?
Block calcium channels, so reduce electrical conduction in the heart. Reduce contractibility - lead to arterial dilation.
31
Verapamil (CCB) side effect?
Constipation
32
Digoxin is an example of?
Antiarrhythmic drug - used in AF
33
What is the mechanism of action of beta-blockers?
Reduce renin release and cardiac contractility
