25
What do Ca channel blockers do?
They limit muscular contraction by blocking the movement of calcium.
26
How do Ca channel blockers affect heart rate and contractility?
They decrease heart rate (negative chronotropic) and decrease myocardial contractility (negative inotropic).
27
What is the effect of Ca channel blockers at low doses?
They relax the smooth muscles in arterioles, resulting in reduced BP.
28
What is an example of a non-selective Ca channel blocker?
Verapamil
29
What is an example of a selective Ca channel blocker?
Nifedipine (Adalat)
30
What is an example of another non-selective Ca channel blocker?
Diltiazem
31
What are the adverse effects of Ca channel blockers?
They may cause reduced BP and bradycardia.
32
What do direct vasodilators do?
They directly relax arteriolar smooth muscle, causing vasodilation.
33
How quickly do direct vasodilators affect BP?
They quickly lower BP.
34
What is an example of a direct vasodilator?
Hydralazine (Apo-hydralazine)
35
What do alpha-1 receptor blockers do?
They dilate arteries and veins to decrease peripheral vascular resistance (PVR) and lower BP.
36
What is an example of an alpha-1 receptor blocker?
Doxazosin (Cardura)
37
What do alpha-2 receptor agonists do?
They stimulate the brain to decrease sympathetic outflow, thereby lowering BP and reducing renin secretion.
38
What are examples of alpha-2 receptor agonists?
Clonidine, Methyldopa
39
What do beta-receptor blockers do?
They decrease heart rate by blocking beta-receptors.
40
How do beta-blockers affect renin secretion?
They decrease renin secretion.
41
What is an example of a beta-blocker?
Propranolol hydrochloride (Inderal)
42
What is another example of a beta-blocker?
Metoprolol tartrate (Lopressor)
43
What is a third example of a beta-blocker?
Atenolol (Tenormin)
44
What do combination alpha- and beta-receptor blockers do?
They act in the periphery at the heart and blood vessels, providing dual antihypertensive effects.
45
What is an example of a combination alpha- and beta-receptor blocker?
Labetalol hydrochloride (Trandate)
46
What is the main function of antihypertensives?
Lower blood pressure ## Footnote Antihypertensives are medications that help reduce high blood pressure.
47
What is secreted by the liver in the Renin Angiotensin Pathway?
Angiotensinogen ## Footnote Angiotensinogen is a precursor that is converted into angiotensin I.
48
What triggers the kidney to release renin?
Low blood pressure ## Footnote The kidney releases renin in response to decreased blood pressure.
49
What do ACE inhibitors do?
Inhibit Angiotensin Converting Enzyme ## Footnote ACE inhibitors prevent the conversion of Angiotensin I to Angiotensin II.
50
What are common adverse effects of ACE inhibitors?
* Low blood pressure * Fatigue * Cough ## Footnote These side effects may vary among individuals.
51
Name a common ACE inhibitor.
Enalapril (Vasotec) ## Footnote Enalapril is widely used to treat hypertension.
52
What is the function of Direct Renin Inhibitors?
Block conversion of angiotensinogen to angiotensin I ## Footnote These inhibitors directly target the renin enzyme.

What are common adverse effects of Direct Renin Inhibitors?
* Headache * Dizziness * Fatigue ## Footnote These side effects can impact patient compliance.
54
How do Angiotensin II Receptor Blockers (ARBs) work?
Block vasoconstriction and hormone secretion ## Footnote ARBs prevent the effects of angiotensin II after it is formed.
55
What are the effects of ARBs on blood pressure?
* Cause arteriole dilation * Increase sodium excretion * Decrease blood pressure ## Footnote These mechanisms contribute to lowering blood pressure.

Call 911 and take another tablet ## Footnote If chest pain persists, a third tablet can be taken 5 minutes later.
67
What are calcium channel blockers used for?
1st line drugs for chronic stable angina ## Footnote They help to reduce myocardial oxygen demand and alleviate chest pain.
68
What is the function of beta blockers?
Block beta-adrenergic receptors, reducing heart rate and myocardial contractility ## Footnote This results in decreased cardiac workload.
69
What are common adverse effects of beta blockers?
Bradycardia, hypotension, dizziness, fatigue ## Footnote Monitoring heart rate and blood pressure is essential while on beta blockers.
70
What is a contraindication for using beta blockers?
Bronchial asthma ## Footnote Beta blockers can exacerbate bronchospasm in asthmatic patients.
71
What should be monitored when taking beta blockers?
