HEART MEDICATIONS

Question 1

mechanism of action for ANITHYPERTENSIVES

what are the groups for these meds?

Answer 1

decrease blood volume and cause vDilation by DECREASING RENAL ABSORPTION

1. diuretics
2. vasodilators
3. ca+ channel blockers
4. Ace inhibitors
5. ARBS

Question 2

what are the diuretic medications?

Answer 2

furosemide :

thiazide:

spirinolactone :

diuretics = class of antihypertensives

Question 3

what is the drug that belongs to vasodilators and mechanism?

Answer 3

HYDRALAZINE:

opens K+ channel causes K+ to efflux : HYPERPOLARIZATION

Question 4

ca+ channel blockers and their function

Answer 4

VDAN

verapamoil

Diltiazem

Amodipine

Nifedipine

BLOCK Ca+ causes VDilation ( if there was influx ca+ causes contraction and Inc HR)

Question 5

what is lisinopril and its funxtion?

Answer 5

ACE inhibitor:

blocke ACE from converting AT1 -> AT2

Question 6

what class of drug is losartan and fxn

Answer 6

ARBA

angio 2 receptor blocker

Question 7

ANTIANGINALS:

purpose?

examples and mechanism?

Answer 7

ANTI heart attack med for insufficient O2

• NITROGLYCERIN: inc O2 by Vdilation of SM
• PROPRANOLOL ( B blocker) : dec O2 demand by relaxing heart
• Ca+ CHANNEL BLOCKER: dec O2 demand by dec peripheral restiatnce by V dilation

Question 8

ANTI CONFESTIVE HEART FAILURE MEDS:

• purpose of them?
• classes and medications in each one

Answer 8

stop heart failure by incblood pump inotropy, HR, etc

CARDIAC GLYCOSIDES:

block na/K ATPase = ^ Ca+ influx = ^ intropy

• dogoxin
• digitalis

ACE INHIBITORS:

stop conversion of AT1 -> AT2 b/c AT2 is a potent vconstrictor that causes heart failure

dilation to impromse blood flow

• lisinopril

Question 9

ANTI ARRYHMATICS:

function?

drug classes and examples and what arrythmias they treat ?

Answer 9

inc refractort period / decrease cardiac excitability :

• class 1: na+ blocker : Quinidine / Lidocaine
• class 2 : Beta- blocker : Propranolol
• Class 3: K+ blocker :
• Class 4: Ca+ blocker: Verapamil
• glycosides : digoxin / digitalis

Class 1 :

• Quinidine : Supravent tachy / afib
• Lidocaine: Vent Arrythmia

Class 2:

• paroxy. tachhy

class 3:

Class 4:

• supravent tachy / paroxy tachy

Glycosides:

Paroxy tachy / Afib
