Three major conditions that require treatment
|
Hypertension
Congestive heart failure Coronary artery insufficiency with angina |
|
when use diuretics?
|
high risk situation (as with a diabetic patient, or one with heart disease) the first class of drugs we use is the diuretics (so-called water pills)
|
|
These reduce blood pressure by decreasing blood volume through increased urine production.
All these enhance water and sodium secretion. Their effect on other ions depends on the drug, but most diuretics lower body potassium and calcium, and the patient is often put on potassium and calcium supplements |
diuretics
|
|
the main side effect of most diuretics (such as Diuril) is
|
low serum potassium and calcium
|
|
spironolactone (Aldactone) and Dyrenium (turns urine blue!).
are? |
Potassium sparing diuretics
|
|
Alpha and Beta Sympathetic Blocking drugs: these agents are widely used to treat
|
hypertension
|
|
Relax the blood vessels and lower pressure. These drugs relax smooth muscles all over the body, also improving urine flow in men with prostate enlargement
|
Alpha blockers
|
|
for high blood pressure
alpha blocker |
Minipress
|
|
for urinary stream blockage
Alpha blocker |
Flomax
|
|
This class of drugs slows the heart rate and force of contraction, thereby also reducing blood pressure
|
Beta blockers
|
|
Examples include propanolol (Inderal), metoprolol (Lopressor) and bisoprolol (Zebeta)
|
beta blockers
|
|
These medicines also reduce the risk of some abnormal heart rhythms
reduce signs and symptoms of heart failure and improve heart function |
beta blockers
|
|
the standard drug for heart failure for a long time
|
Digitalis
|
|
first described in the medical literature in 1785 by William Withering
|
Digitalis
is herb aka fox glove |
|
Increases the force of contraction of myocardial muscle cells by its effects on increasing calcium and sodium in the heart muscle cells
|
digoxin
|
|
bradycardia, and an irritable heart muscle that is prone to arrhythmias are side effects of what drug
|
Digitalis side effects
|
|
Digitalis
Beta blockers Strong diuretics, such as Lasix Calcium channel blockers Renin-angiotensin system drugs: are classes of drugs to treat what? ACE inhibitors (angiotensin converting enzyme inhibitors) Angiotensin II receptor blockers Renin inhibitors |
Classes of drugs to treat heart failure
|
|
This class of drugs slows the heart rate and reduces blood pressure.
Examples include propanolol (Inderal), metoprolol (Lopressor) and bisoprolol (Zebeta) |
Beta blockers
|
|
for heart failure include furosemide (Lasix) and bumetanide (Bumex).
Nothing else is as powerful as these two drugs in getting unwanted fluid out of the body. These drugs also decrease fluid in the lungs, so the patient can breathe more easily |
Diuretics
|
|
These drugs include spironolactone (Aldactone) and eplerenone (Inspra).
|
Potassium-sparing diuretics
|
|
These drugs also have a role in treating hypertension, but their main usage is in treating heart disease.
They block the release of calcium from the muscle cell channels (where it resides when it is inactive) which is an all important step in smooth and cardiac muscle contraction |
Calcium Channel Blockers
|
|
These drugs are especially useful in patients (often young men and women) who suffer from episodes of PAT (also known as SVT: supra-ventricular tachycardia).
|
calcium channel blockers
|
|
nifedipine (Procardia®) and diltiazem (Cardizem®)
|
Other calcium channel blockers
|
|
__________ may be used in conjunction with a beta blocker in treating heart disease. The cardiologist can individualize such treatment.
|
calcium channel blockers
|
|
These block the formation of angiotensin II, so there is less vasoconstriction. This is helpful when the heart is struggling to pump blood against a high pressure in the systemic circulation.
Examples include enalapril (Vasotec), lisinopril (Prinivil, Zestril) and captopril (Capoten) |
Angiotensin-converting enzyme (ACE) inhibitors
|
|
These drugs block the receptors in the smooth muscle cells that surround the blood vessels
Examples are losartan (Cozaar) and valsartan (Diovan) |
Angiotensin II receptor blockers
|
|
A new class of drugs that block the action of renin on angiotensinogen so it does not get converted to angiotensin I.
Example: Aliskirin (Tekturna), remikirin |
Renin inhibitors
|
|
Nitroglycerin remains the most commonly used agent for
|
angina
|
|
Side effects are few, but sometimes include hypotension, with the possibility of rebound tachycardia because of falling blood pressure, which can then make the angina worse
|
Nitroglycerin
|
|
counteract the firing of the beta fibers of the sympathetic nervous system which in an emergency cause the heart to beat faster
They are often used to treat PAT: paroxysmal atrial tachycardia, a condition commonly affecting young people, especially women in their teens and 20’s. It is also called PSVT Inderol (propanolol) |
Beta Blockers for tachycardia
|
|
New” wonder drugs for severe dyspepsia, ulcers, and GERD (gastroesophageal reflux disorder)
Inhibit the formation of HCL in the pareital cells of the stomach |

Also very popular: Ranitidine: Zantac |
Histamine 2 receptor antagonists (sometimes called H2 receptors)
|
|
