Digonin is synthesized by the hypothalamus in the human body. Outside the body digoxin is extracted from a leaf off the digitalis lanata plant. Digoxin is a white crystal that melts at 230o with no odor; it is not insoluble in water. Digoxin is available in tablets, oral solution and IV. Digoxin comes from cardiac glycosides class of medication. Digoxin is a generic name for Lanoxin. Other brand names for digoxin are cardoxin, digitek, lanoxicaps, and lanoxin. Digoxin contains active ingredients. Digoxin also contains other, additional ingredients that help ensure the stability, safety and effectiveness of the medicine. These other ingredients are added to improve the medicine’s taste and appearance and to make it easier for the patient to swallow; they also prolong the life of the medicine.
Digoxin is primarily used to treat heart failure, by increasing the physical strength and force of heart’s contractions. In turn increases the output of blood from the heart, this increase is done by inhibiting the enzyme ATPase (the release of energy to make chemical reactions occur within the cells) which controls circulation of calcium, sodium, and potassium into the heart muscle. Inhibiting ATPase brings a rise in intercellular calcium which increases the force of heart contractions and the contracture of smooth vascular muscle, the sodium pump moves the sodium ions out of and the potassium ions into the cells.
Digoxin is also a medicine which is used in heart rhythm disorders. Digoxin will slow the heart rate and help the heart beat more regularly when in arrhythmia. Normal heartbeats that pump blood rely on regular electrical impulses. Irregular electrical impulses (arrhythmia) can alter, reduce, and even stop the hearts...

...rning that digoxin may cause severe sinus bradycardia or sinoatrial block in patients with pre-existing sinus node disease and may cause advanced or complete heart block in patients with pre-existing incomplete AV block. These patients should be given a pacemaker before treatment with digoxin. Another warning is that the accessory AV pathway should be blocked before the patient is given digoxin. Without the block antegrade conduction across the accessory pathway can bypass the AV node and cause rapid ventricular response. Also patients with heart failure can become toxic of the digoxin. Patients with this toxicity should not be given digoxin.
Heart failure and irregular heart beat can both be very serious conditions, there is no direct cure for these ailments. However with digoxin the symptoms can be prolonged for quite some time.

It occurs because of repetitive electrical activity. This can occur in a patient with early or late heart failure, because there is damage to the heart tissue and the heart beats faster to try to supply the body with blood. Recommended treatment is elective cardioversion. Drugs used include an antidysrhythmic such as Mexitil or Sotalol (Ignatavicius &Workman, p. 728-729).
Heart disease is the leading cause of death in the United States and the estimated cost of treatment is $32 billion yearly. Approximately 5 million people living in the United States suffer from congestive heart failure (CHF) and half of those diagnosed will die within 5 years. An individual may present to the hospital with weakness, short of breath (SOB), swelling of the extremities, ascites, and breathing difficulties while lying down. The quality and length of life for someone suffering from heart failure can be improved with early diagnosis, medication, physical activity, and diet modification (CDC, 2013).
Dealing with alcohol withdrawal, Atenolol can be used as an addition to tradition alcohol withdrawal treatment to help make the results more effective. In relation to anxiety disorders, atenolol is usually used in small stress reactions, minor panic disorders, and generalized anxiety syndrome. Results are most easily obtainable in patients who have bodily anxiety, as opposed to the mind, and helps reduce trembling and rapid heart beat. Atenolol also had a large affect on cardiac illnesses. In the most common, angina pectoris, atenolol is used to decrease the amount of repeated attacks and to prevent any immediate death. Atenolol is best effective on middle-aged or teenagers, and to those with high blood pressure and heart rate as a result of exercise. The other major heart sickness is congestive heart failure. Giving Atnolol to a person with congestive heart failure must be taken with much care and precauution. One should start with low doses at first, and as time passes, increase the intake gradually. Overall, it affects the heart and circulatory system to either lessen the effect of or prevent any type of cardiovascular illness that may cause serious and/or permanent damage to the body. But how exactly does the medication work?

Why do consumers purchase specific drugs for various ailments, sicknesses or diseases they might have? Why do physicians prescribe certain drugs over competitive drugs that may be available to the public? Why is it that most of us can easily name specific drugs that fit the many ailments of today’s society? On the surface the answer might be as simple as good TV advertising or radio commercials or even internet adds. The truth of matter is the major pharmaceutical manufacturers own the patents on these drugs and this gives them all of the marketing budget and muscle they need to promote the drug and control the pricing. The incentives for larger pharmaceutical companies are very enticing and as a result, they don’t mind spending the time in clinical trials and patent courts to get their drugs approved. Some will even get patents on the process by which the drug is manufactured, ensuring that no competitor can steal the drug or the process. This protects their large financial investment and nearly guarantees a large return for their investors. Many consumer rights groups claim this is nothing more than legalizing monopolies for the biggest manufacturers.
Congestive Heart Failure is when the heart's pumping power is weaker than normal. It does not mean the heart has stopped working. The blood moves through the heart and body at a slower rate, and pressure in the heart increases. This means; the heart cannot pump enough oxygen and nutrients to meet the body's needs. The chambers of the heart respond by stretching to hold more blood to pump through the body or by becoming more stiff and thickened. This only keeps the blood moving for a short while. The heart muscle walls weaken and are unable to pump as strongly. This makes the kidneys respond by causing the body to retain fluid and sodium. When the body builds up with fluids, it becomes congested. Many conditions can cause heart failure, and they are Coronary artery disease, Heart attack, Cardiomyopathy, and conditions that overwork the heart.
The sufferers might be treated with the use of calcium channel blockers which will expand the affected arteries so that blood can flow more freely.
In the case a patient has a hypersensitivity to it they could suffer from anaphylactic shock, bronchospasms, or possibly tachycardia. The most common adverse reaction is prolonged paralysis, which can be countered with mechanical respiration until recovery is adequate. This reaction more common when the drug is used in a long term situation. Drugs such as edrophonium pyridostigmine, or neostigmine could be used to counter the effects of vecuronium as well. Vecuronium has very little cardiovascular effects even in large doses which is why it is used so often in surgery (Determination
...blood and increase the absorption and concentration of digoxin in the blood. This may reduce the effectiveness of ketoconazole or increase digoxin toxicity. Through unknown mechanisms, omeprazole may increase blood levels of saquinavir and reduce blood levels of nelfinavir and atazanavir, drugs that are used for treating patients with infection caused by the human immunodeficiency virus (HIV). Omeprazole can be contraindicated in patient with hepatic impairment thus doctors are advised not to prescribe more than 20mg daily of omeprazole for such patients. [1] [3] [4]
Digoxin (Lanoxin) 250 mcg daily: In heart failure, increases contractility by inhibiting sodium/potassium ATPase pump in myocardial cells promoting calcium influx via sodium –calcium exchange pump ("Digoxin," 2015, p. 6).
Dilated cardiomyopathy accounts for approximately 15% of heart failure cases in the under 75s (“Chronic Heart Failure”). Patients with Dilated cardiomyopathy are usually unaware of the disease until they experience the signs and symptoms of heart failure or they develop an arrhythmia.
Bradycardia can be very serious. Some of the symptoms are loss of consciousness, heart failure, or death. Slow heart rates are caused by heart block. The hearts natural pace-maker fails to be conducted to the ventricles, the hearts main pumping chambers.
...lso recommended not only for patients with dysrhythmias, but for everyone. It promotes a positive attitude, gets the blood flowing and is shown to reduce stress levels (Shea & Sears, 2008)
It is prescribed after many types of injury, illness, or disease, including amputations, arthritis, cancer, cardiac disease, neurological problems, orthopedic injuries, spinal cord injuries, stroke, and traumatic brain injuries. The Institute of Medicine has estimated that as many as 14% of all Americans may be disabled at any given time. (n.d.)
