Q

Action of non dihydropiridine blockers

A

Reduce CMV, peripheral arterial dilation,coronary artery dilation,diastole prolongation and reduce AV conduction

29

CCB acts on

A

L type voltage dependent calcium ion channels

30
Q

Undamaged endothelium releasing NO and PGI2

A

Inhibits platelets activation

31
Q

CCB s are

A

Metabolic poison , because it increases dependence on carbohydrate metabolism than FFA

32
Q

CcBs cause

A

Coronary and peripheral vasodilation, decrease heart contractility,,slowed AV nodal conduction and depressed SA node activity

33
Q

Beta blockers and verapamil interactions cause

A

Bradyarrythmia and if used parentaral asystole

34
Q

Inhibitors of cyp450

A

Macrolide antibiotics and grapefruit juice

35

A

Vasodilatory shock

37
Q

Verapamil and diltiazem cause

A

Vasodilatory and cardiogenic shock+bradycardia

38
Q

Bradycardia can be caused by

A

Sinus bradycardia, second or 3rd degree AV block or sinus arrest

39
Q

CCB doesn’t affect

A

QRS duration

40
Q

CCB toxicity can be treated by

A

Calcium chloride or calcium gluconate for cardiac contraction, insulin against hyperglycaemia, Epinephrine, dobutamine or isoproterenol against cardiogenic shock and phenylephrine and norepinephrine against vasodilatory shock

41

A

Prevention of angina attack

45
Q

Side effects of BAB
