Q

Spironolactone Adverse Effect

A

Hyperkalemia
NEVER USE IF K>5, caution with ACE inhibitors, ARBs
endocrine effects
gynecomastia
impotence
menstrual irregularities

17
Q

Normal K level

A

3.5-5 mmol/L

18
Q

Diuretic can decrease blood volume result in

A

decrease:
preload
PE
peripheral edema

19
Q

Canagliflozin

A

Sodium-Glucose Co-Transporter inhibitor
Inhibit SGLT-2 in the kidney to reduce reabsorption of glucose
Cause osmotic diuresis which decrease decreases overall blood volume

20
Q

Canagliflozin indication

A

Diabetes HF

21
Q

Adverse Effect of Canagliflozin

A

Yeast infection in females, UTI, polyuria, dehydration, hyponatremia, hypotension

22
Q

Sacubitril/Valsartan

A

Angiotensin Receptor inhibitor
Sacubitril - inhibits neprilysin leading to increase natriuretic; induces vasodilation and natriuresis (secretion of Na by kidney)
Valsartan - ARB

23
Q

Sacubitril/Valsartan indication

A

HF

24
Q

Sacubitril/Valsartan Adverse Effect

A

Hypotension
increase K, Cr
Watch for dehydration and electrolyte imbalance, renal failure

25
Q

Digoxin

A

Cardiac Glycosides
Increases myocardial activity by inhibiting enzyme known as Na/K - ATPase which causes Ca to accumulate in myocytes leading to increase force of contraction (Increase CO), decrease HR, decrease AV node conduction

26
Q

Digoxin Indication

A

HF and Afib

27
Q

Digoxin Adverse effect

A

Dysrhythmias
Bradycardia
Hypotension
GI disturbances (anorexia, N/V)

28
Q

Amiodarone

A

K channel blocker, prolonging the resting tissue for heart
Less AF to be conducted
Change the rhythm
SHORT TERM DRUG because pulmonary toxicity, damage to pulmonary, liver, thyroid

29
Q

Amiodarone indication

A

Atrial and Ventricular Arrhythmias

30
Q

Amiodarone Adverse Effect

A

Pulmonary toxicity
Thyroid toxicity
Liver toxicity
