Term
The drug suffix 'ine' refers to what type of drug?
Definition

Term
The drug suffix 'pril' refers to what type of drug?
Definition

(ACE=angiotensin converting enzyme)

Term
The drug suffix 'sartan' refers to waht type of drug?
Definition

List 3 examples of Beta blockers
Definition

Atenolol

Betaxolol

Metoprolol

Propanolol

Term
Centrally Acting Adrenergic Blockers
Definition
Clonidine and alpha-methyldopa
Term
Angiotensin converting enzyme converts __________into _____________
Definition
Angiotensin I into angiotensin II
Term
How does Angiotensin II increase blood pressure?
Definition
By stimulating aldosterone, which causes retention of sodium in the kidneys, and in turn the retention of water.
Term
Describe the mechanism of ACE inhibitors
Definition
By inhibiting the action of ACE, angiotensin II is not secreted, thus aldosterone is not stimulated and blood volume is not increased. Thus blood pressure does not increase, reducing hypertension
Term
Name 2 side effects of ACE inhibitors
Definition
Hyperkalemia (too much potassium)and photosensitivity, dry cough
Term
Name 4 ACE inhibitors
Definition

Captopril

Enalapril

Lisinopril

Ramipril

Term
Describe another mechanism of inhibiting the effects of angiotensin II other than ACE inhibitors
Definition
Angiotensin II receptor blockers
Term
What 2 conditions are Angiotensin II Receptor Blockers used to treat
Definition

Congestive Heart Failure

Hypertension

Term
How do Angiotensin II Receptor Blockers reduce blood pressure?
Definition

blocking vasoconstriction

blocking aldosterone secretion

Term
Name 2 Side effects of angiotensin II receptor blocker 
Definition

Hyperkalemia

Cough (though not as bad as with ACE inhibitors)

Term
Name 3 Angiotensin II Receptor Blockers
Definition

Bisoprolol

Losartan

Valsartan

Term
Name 4 Side effects of Calcium channel blockers
Definition

CONSTIPATION

flushing

dizziness

fatigue

hypotension

headache

Term
Describe how vasodilators reduce blood pressure
Definition
They cause the relaxation of vascular muscle, which in turn causes dilation of blood vessels, thereby reducing peripheral resistance and thus blood pressure. 
Term
What other types of drugs are vasodilators used in combination with?
Definition

Beta blockers

Diuretics

Term
Why do vasodilators cause headaches?
Definition
The dilation of blood vessels in the brain causes headaches.
Term
Name 2 Side effects of vasodilators
Definition

Headache

Tachycardia

Term
Name 2 of the 3 vasodilators mentioned in the notes
Definition

Fenoldopam

Hydralazine

Minoxidil (Rogaine)

Term
What are the first 2 methods of treating mild to moderate hypertension
Definition

Prescribe a diuretic

Decrease sodium intake in diet

Term
How do diuretics promote water loss?
Definition

By blocking reabsorption of Na and Cl

 

Term
Name the 2 most common type of diuretics
Definition

Thiazide Diuretics

Thiazide-like diuretics

Term
On what part of the nephron do the thiazide and thiazide-like diuretics act?
Definition
On the distal convoluting tubules and collecting ducts. 
Term
What is a common side effect of thiazide/thiazide-like diuretic?
Definition

Loss of potassium (hypokalemia)

loss of sodium

jaundice 

possibly gout

Term

Name 2 Thiazide diuretics

 

Name 2 Thiazide-like diuretics

Definition

Hydrochlorothiazide and Polythiazide


Chlorthalidone and Indapamide

Term
How do Loop diuretics compare in strength to thiazides?
Definition
They have a much more rapid and potent effect than thiazides. 
Term
Name two conditions loop diuretics are used to treat
Definition

Acute pulmonary edema (CHF)

Hypertension

Hypercalcemia

Term
Name 3 side effects of loop diuretics
Definition

OTOTOXICITY

hypokalemia

hyponatremia (reduced sodium levels)

Term
Name 3 examples of loop diuretics
Definition

Furosemide

Ethacrynic acid

Bumetanide

Term
Why are potassium sparing diuretics better than loop diuretics?
Definition
they produce a mild diuresis without affecting potassium levels
Term
What type of diuretic is spironolactone and how does it work?
Definition

It is a potassium sparing diuretic

It decreases Na reabsorption by blocking aldosterone. 

Term
How do Amiloride and Triamterene affect diuresis?
Definition
They are potassium sparing diuretics that work by blocking the epithelial sodium channels
Term
Which parts of the nephron do potassium sparing diuretics work on?
Definition
Distal convoluted tubules and collecting ducts. 
Term
Name a common side effect of potassium sparing drugs and describe a way to avoid this side effect.
Definition

SE: hyperkalemia

Best to pair with a loop/thiazide diuretic to balance out potassium levels. 

Term
Out of the 4: chylomicrons, VLDL, LDL and HDL which is the largest? Which is the most dense?
Definition

Chylomicrons are the largest

HDL's are the most dense

Term
What is the suffix for HMG CoA Reductase Inhibitors
Definition
'statin'
Term
What is the best drug for increasing good cholesterol levels?
Definition
Niacin
Term
How does Ezetimibe affect hyperlipidemia?
Definition
Ezetimibe is a cholesterol absorption inhibitor
Term
How do Bile acid sequestrants reduce hyperlipidemia?
Definition
They bind with bile salts in GI, forming insoluble complexes, so fats cannot be absorbed into the bloodstream, they are excreted instead.
Term

Name 4 drug types for reducing hyperlipidema.

Which is the most effective for reducing cholesterol and LDL levels?

Definition

Bile Acid Sequestrants

HMG CoA Reductase Inhibitors (Statins)

Fibric Acid Derivatives

Term
Name 2 SE of Bile Acid Sequestrants
Definition

Name 2 Bile Acid Sequestrant Drugs
Definition

Cholestyramine

Colestipol

Term
What are the side effectsof Niacin/Nicotinic Acid?

Term
Name 3 Statins
Definition

Term
Name 3 Contraindications for Statins
Definition

Liver problems (hepatotoxicity)

Muscle problems (myopathy)

Contraindicated for pregnancy

Term
Describe the action of Fibric Acid Derivatives
Definition

-block hepatic of FAs

inhibit TG production

Term
What lipid types do Fibric Acid derivatives affect?
Definition
They decrease VLDLs and TG, while increasing HDLs.
Term
Name 2  Fibric Acid Derivatives and name 2 common side effects
Definition

Clofibrate and Gemfibrozil.

SE: Easy brusing and epistaxis (nose bleeds)

Term
How do statins work?
Definition
They are structurally analagous to HMG-CoA and thus they inhibit HMG-CoA Reductase. HMG CoA Reductase plays a role in cholesterol production, thus its inhibition disrupts to synthesis of cholesterol
