Common Respiratory Ailments And Medications/Treatments


Asthma (AZ-ma)
Respiratory disease often caused by an allergy that is marked by tightness in the chest and difficulty in breathing. Asthma is a chronic (long-term) inflammatory disease of the airways. Although the cause for the condition is unknown, it is known that allergies can trigger an asthma attack. Continuing inflammation makes the airways hypersensitive to stimuli such as cold air, exercise, dust mites, air pollutants, and even stress and anxiety. All can then give rise to an asthma attack. Asthma usually begins in childhood or adolescence, but it also may first appear during adult years. An estimated 15 million people in the United States suffer from asthma. More than 5,600 people die of severe asthma attacks each year.

Medication/Treatment

Most asthma medications work by relaxing bronchospasm (bronchodilators) or reducing inflammation (corticosteroids). In the treatment of asthma, inhaled medications are generally preferred over tablet or liquid medicines, which are swallowed (oral medications). Inhaled medications act directly on the airway surface and airway muscles where the asthma problems initiate. Absorption of inhaled medications into the rest of the body is minimal. Therefore, adverse side effects are fewer as compared to oral medications. Inhaled medications include beta-2 agonists, anticholinergics, cirticosteroids, and cromolyn sodium. Oral medications include aminophylline, leukotriene antagonists, beta-2 agonists, and corticosteroid tablets.

Bronchitis (bron-KIE-tis)
Inflammation of the mucous membrane of the bronchial tubes. Bronchitis is an inflammation of the mucous membranes of the lower respiratory passages, especially the trachea and bronchi. Bronchitis can either be acute (short-term) or chronic (long-term). A comparison of normal bronchioles and those of an asthma sufferer. Acute bronchitis usually follows a viral infection such as a cold or the flu. Anyone can be afflicted with the disorder, but infants, young children, and the elderly are more susceptible because their body immunity (ability to fight disease) is generally weaker. Acute bronchitis usually begins with the symptoms of a cold: runny nose, sneezing, and a dry cough. However, the cough soon becomes deep and painful, and it will bring up greenish-yellow phlegm. High fever and wheezing are also common. If no additional infection is present, acute bronchitis is treated in the same way as the common cold: drinking plenty of fluids, resting, not smoking, and taking acetaminophen for fever and pain. If an additional infection exists, the infection is treated with an antibiotic. When treated, acute bronchitis usually resolves in one to two weeks without complications. Chronic bronchitis is a major cause of disability and death in the United States, affecting an estimated 14 million people. The disorder is caused by inhaling respiratory irritants, especially cigarette smoke. The American Lung Association estimates that 80 to 90 percent of all cases are caused by smoking. Other irritants include chemical fumes, air pollution, mold, and dust. Chronic bronchitis develops slowly over time. When smoke or other irritants are inhaled, the cilia projecting from the mucous membrane lining the respiratory tract become paralyzed or snap off. Airways then become inflamed, narrowed, and clogged with mucus, making breathing difficult. A mild cough, sometimes called smokers' cough, is usually the first symptom. Wheezing and shortness of breath may accompany the cough. As the disease advances, breathing becomes even more difficult and activity decreases.

There is no cure for chronic bronchitis and treatment to help reduce symptoms is complex. As in asthma attacks, drugs may be given to relax the muscles of the bronchial tubes and allow increased air flow. The drugs may be taken by mouth or inhaled through a nebulizer, a device that delivers a regulated flow of medication into the airways. To further reduce the swelling of airway tissue, anti-inflammatory drugs may also be prescribed. As the disease progresses, an individual may be required to breathe supplemental oxygen. The best way to prevent either type of bronchitis is to stop smoking or not even to begin.

Medication/Treatment

Short-term steroid therapy will help minimize inflammation within the bronchial tubes. Prednisone is a common prescription medication that enhances the anti-inflammatory effects of the steroids produced within the body by the adrenal glands. Topical inhaled steroids may also be of benefit with fewer potential side effects.

Cystic fibrosis (SIS-tik fie-BRO-sis)
Genetic disease in which, among other things, the mucous membranes of the respiratory tract produce a thick, sticky mucus that clogs airways. Cystic fibrosis is an inherited or genetic disease, meaning it is caused by a defect in a person's genes. It affects the lungs, digestive system, sweat glands, and male fertility (ability to produce offspring or children). The disease affects about 30,000 children and young adults in the United States. Approximately 3,000 babes are born each year with cystic fibrosis. Cystic fibrosis affects the body's ability to move salt and water in and out of cells. This defect causes the lungs and pancreas to secrete thick mucus, blocking passageways and preventing proper functioning. The disease derives its name from the fibrous scar tissue that develops as a result in the pancreas. In the lungs, the thickened mucus increases irritation and inflammation of lung tissue. This inflammation swells the passageways, partially closing them down. At the same time, infection from bacteria or viruses becomes more likely since the mucus is a rich source of nutrients. Bronchitis and pneumonia frequently develop in individuals with cystic fibrosis. The body's response to the infection is to increase mucus production. White blood cells fighting the infection thicken the mucus even further as they break down and release their cell contents. These white blood cells also provoke more inflammation. The process is a downward spiral as a person suffering from the disease experiences ever-increasing shortness of breath and tiredness. Untreated, cystic fibrosis leads to severe lung infection, which is the primary cause of death. There is no cure for cystic fibrosis. Regular monitoring and early treatment are key to maintaining respiratory health. Good general health, especially good nutrition and exercise, can keep the body's immune response working properly. This, in turn, can help decrease the number of infections started by the bacteria always present in the lungs of infected individuals. Clearing mucus from the lungs also helps to prevent infection, and devices and techniques have been developed to help in this regard. Several drugs are available to prevent the airways from becoming clogged with mucus. Lung transplants have become increasingly common for people with cystic fibrosis. About 50 percent of adults and 80 percent of children who receive lung transplants live longer than two years.

Medication/Treatment

Cystic fibrosis (CF) has no cure. However, treatments have greatly improved in recent years. The goals of CF treatment include:
  • Preventing and controlling lung infections
  • Loosening and removing thick, sticky mucus from the lungs
  • Preventing or treating blockages in the intestines
  • Providing enough nutrition
  • Preventing dehydration (a lack of fluid in the body)
 Breathing techniques also may help dislodge mucus so you can cough it up. These techniques include forcing out o couple of short breathe or deeper breaths and then doing relaxed breathing. This may help loosen the mucus in your lungs and open your airways.

If you have CF, you doctor may prescribe antibiotics, anti-inflammatory medicines, bronchodilators, or mucus-thinning medicines. These medicines help treat or prevent lung infections, reduce swelling, open up the airways, and thin mucus.

Emphysema (em-feh-ZEE-mah)
Respiratory disease marked by breathlessness that is brought on by the enlargement of the alveoli in the lungs. Emphysema is a respiratory disease marked by breathlessness that is brought on by the enlargement of the alveoli in the lungs. It is the most common cause of death from respiratory disease in the United States. Emphysema occurs mainly among people who are fifty years of age or older. Heavy cigarette smoking is the primary cause of the disease, although a few cases are caused by an inherited defect. When a person inhales cigarette smoke, that person's body releases substances that are meant to defend the lungs against the smoke. These substances can also attack the cells of the lungs. Normally, the body prevents such action by releasing other substances. In smokers and those with the inherited defect, no such prevention occurs. Lung tissue is then damaged in such a way that it loses its elasticity. Bronchioles collapse, trapping air in the alveoli. Unable to contract efficiently and move air out, the alveoli over expand and rupture. The alveoli blend together, forming large air pockets from which air cannot escape. This cuts down the surface area for gas exchange. As the disease progresses, coughing and shortness of breath occur. Exhaling becomes difficult. Over several years, the extra work of exhaling can cause the chest to enlarge and become barrel-shaped. Emphysema is a serious and long-term disease that cannot be reversed. The body cannot repair the damage to the lungs. Ultimately, the disease can lead to respiratory failure. If emphysema is detected early, medications may be given to help relax and open air passages, thus reducing some of the symptoms. Mild exercise may be ordered to help strengthen muscles involved in A healthy lung (on the left) and a smoker's lung (on the right). An individual suffering from emphysema must stop smoking immediately or no treatments will be effective at all.

Medication/Treatment

Emphysema is not a curable disease, once lung damage has occurred it cannot be reversed. The goal of treatment is to stop further lung destruction and preserve lung function. The patient needs to know that the focus is on improving quality of life and limiting the intrusion of emphysema on daily activities. Emphysema tends not to be the primary cause of death, but can be a contributing factor to other organ failure.


The number one treatment goal is to have the patient stop smoking. Education, counseling, support groups and medication may be used. Moreover, prevention is most important, and not starting to smoke is much easier than helping a person to quit smoking.

Lung cancer
Lung cancer develops when cells of the lung tissues become abnormal and grow uncontrollably, forming tumors. It is the leading cause of death from cancer among both men and women in the United States. Approximately 160,000 people die from the disease each year. Tobacco smoking is the leading cause of lung cancer. Ninety percent of lung cancers can be prevented by giving up tobacco. Smoking marijuana cigarettes is considered yet another risk factor for lung cancer. These cigarettes have a higher tar content than tobacco cigarettes. In addition, they are inhaled very deeply. As a result, the smoke is held in the lungs for a longer time. Other causes of lung cancer include exposure to asbestos, toxic chemicals, radioactive minerals, environmental pollution (such as auto exhaust fumes), and a family history of lung cancer. Lung cancers tend to spread very quickly to other parts of the body. Early symptoms to watch for include a cough that does not go away, chest pain, shortness of breath, persistent hoarseness, swelling of the neck and face, significant weight loss, unexplained fever, bloody or brown-colored spit or phlegm, and recurrent lung infections. The most common treatment options for lung cancer include surgery, chemotherapy, and radiation. During surgery, surgeons may remove a small part of the lung, one lobe of the lung, or the entire lung. The extent of the surgery depends on how much of the lung is affected. After the cancer has been removed, the physician may recommend chemotherapy (using a combination of drugs to kill any remaining cancer cells and shrink any tumors) or radiation therapy (using X rays or other high-energy rays to kill any remaining cancer cells and shrink any tumors) or a combination of both. Either or both of these methods may be used to shrink the tumor before surgery is attempted. Almost 50 percent of lung cancer patients survive if the cancer is detected before it has had a chance to spread to other organs and it is treated appropriately. Only 15 percent of lung cancers, however, are found at this early stage. The best way to prevent lung cancer is not to smoke at all or to quit smoking if one has already started. Secondhand smoke from other people's cigarettes should also be avoided.

Medication/Treatment


There are a number of different treatment options for lung cancer. Standard treatment options include surgical resection, chemotherapy, and radiation therapy. Newer lung cancer treatment approaches include photodynamic therapy, electrocautery, cryosurgery, laser surgery, targeted therapy and internal radiation. Each lung cancer treatment has its own specific ability to fight cancer and its own set of side effects and possible complications. Therefore while there are many options, lung cancer treatment needs to be performed judiciously and only after very careful consideration of a number of factors.

Pneumonia (noo-MOE-nya)
Disease of the lungs marked by inflammation and caused by bacteria or viruses. Pneumonia is an infection of lung tissues. It can be caused by nearly any organism known to cause human infections. This includes bacteria, viruses, fungi, and parasites. Pneumonia is the sixth most common disease leading to death in the United States. It is also the most common fatal infection acquired by people who are already hospitalized. Pneumonia develops when the several types of immune substances in the respiratory tract are weakened to the point where invading organisms can take over. Once they do so, an infection develops in the normally sterile environment of the lungs. Symptoms include fever, cough, chest pain, shortness of breath, and increased respirations (number of breaths per minute). Many people cough up sputum (commonly known as spit) streaked with pus or blood. Breathing is not the only process by which humans move air in and out of the lungs. Some processes or actions are reflexes initiated to clear air passages. Others are indications or extensions of emotional states.

Two vaccines are available to prevent pneumococcal disease: the pneumococcal conjugate vaccine (PCV13) and the pneumococcal polysaccharide vaccine (PPV23; Pneumovax). The pneumococcal conjugate vaccine is part of the routine infant immunization schedule in the U.S. and is recommended for all children < 2 years of age and children 2-4 years of age who have certain medical conditions. The pneumococcal polysaccharide vaccine is recommended for adults at increased risk for developing pneumococcal pneumonia including the elderly, people who have diabetes, chronic heart, lung, or kidney disease, those with alcoholism, cigarette smokers, and in those people who have had their spleen removed. This vaccination should be repeated every five to seven years, whereas the flu vaccine is given annually.

Tuberculosis (too-burr-cue-LOW-sis)
Infectious, inflammatory disease of the lungs caused by a bacteria that results in tissue damage. In an asthma attack, the muscle tissue in the walls of the bronchi and bronchioles go into spasm. As a result, the cells lining the airways swell and secrete mucus into the air spaces. Both these actions cause the bronchi and bronchioles to become narrowed. This, in turn, produces a tightness in the chest, wheezing, and breathlessness, sometimes to the point where an individual gasps for air. Asthma attacks come and go in irregular patterns, and they vary in degree of severity. Some may last only a few minutes; others may go on for much longer. Treatment for asthma usually includes identifying the specific substance causing the allergic reaction and subsequently avoiding contact with it. Drugs are often given to relax the muscles of the bronchial tubes and allow increased air flow. They may be taken by mouth or inhaled through a nebulizer, a device that delivers a regulated flow of medication into the airways.

Medication/Treatment


Active TB is treated with a combination of medications along with isoniazid. Rifampin (Rifadin), ethambutol (Myambutol), and pyrazinamide are the drugs commonly used to treat active TB in conjunction with isoniazid (INH). Four drugs are often taken for the first two months of therapy to help kill any potentially resistant strains of bacteria. Then the number is usually reduced to two drugs for the remainder of the treatment based on drug-sensitivity testing that is usually available by this time in the course. Streptomycin, a drug that is given by injection, may be used as well, particularly when the disease is extensive and/or the patients do not take their oral medications reliably (termed "poor compliance"). Treatment usually lasts for many months and sometimes for years. Successful treatment of TB is dependent largely on the compliance of the patient. Indeed, the failure of a patient to take the medications as prescribed is the most important cause of failure to cure the TB infection. In some locations, the health department demands direct monitoring of patient compliance with therapy.
