Q

ACE inhibitors - function and examples

A

Blocks angiotensin converting enzyme so A1 cannot be converted into A2. A2 is a vasoconstrictor
Lowers blood pressure

16
Q

ARBs - main uses

A

Hypertension - if ACEi don’t work
Heart failure

17
Q

ARBs - side effects

A

Renal dysfunction
Never use in pregnancy - induces hypertension (eclampsia)

18
Q

Beta blockers - function and examples

A

Blocks beta receptors causing decreased heart rate and blood pressure

Cardioselective - Atenolol + Bisoprolol
Non-Cardioselective - Propanolol + Carvendilol

19
Q

Beta blockers - main uses

A

Arrhythmia
Concurrent cardiac disease
Non-Cardioselectives can be used in thyrotoxicosis (overactive thyroid) and migrate

20
Q

Beta blockers - side effects

A

Bronospasm - don’t use with asthma
Avoid in patients with raynauds
Hypoglycaemia

Heart failure
Cold peripheries

20
Q

Beta blockers - side effects

A

Cancer
Tired
Heart failure
Cold peripheries

21
Q

Calcium channel blockers - 2 types

A

Dihydropyridines
Rate limiting calcium antagonists

22
Q

Calcium channel blockers - function

A

Blocks calcium channels which means force of contraction is less
Lowers heart rate and blood pressure
Vasodilator

23
Q

CCBs - Dihydropyridines - example, use and side effects

A

Amlodipine

Used in: Hypertension - old and non-Caucasian
