Who is more likely to suffer from asthma?
Asthma is a worldwide disease, more common in urban than rural areas and account for 25 percent of all non-TB chest diseases. It can occur at any age, but in 50 percent of patients, it begins for old times. It is more common in boys than girls, but at the age of 30 years, the incidence is equal. About 25 to 30 percent of children with asthma recover automatically during adolescence, but some recovered a few years later. Asthma acting adult is serious. The attacks are more frequent and prolonged.
With the advancement in methods of treatment, the survival of asthmatics has been significantly than before. The management of asthma includes special treatment aims to remove the cause and treatment of symptoms.
If the cause of asthma can be detected, every effort should be made to remove it to provide complete and permanent relief. If a patient develops symptoms of allergic reactions, such as rash, itching and itching and runny potential allergen extract (substances that cause allergies) should be considered. Its removal is the most effective way to control asthma. If this is not possible, desensitization using an extract of specific allergen should be tried. In many cases of asthma, the specific allergen is not to identify the allergy drugs are tried. Several patients from seasonal asthma benefit from a temporary move to another town for the beginning of a given period, but this is not always feasible.
If infection is the cause, one should protect themselves from stress and strain due to extremes of weather. Frequent attacks cold can lead to asthma. Intensive treatment with certain antibiotics immediately. The most common offending organisms are pneumococcus and Haemophilus influenzae. In these infections, broad-spectrum antibiotics such as amoxycillin, cefuroxime or ampicillin are usually more effective.
drugs that are used to provide symptomatic relief are those that prevent bronchospasm or cause broncho-dilation. This can be divided into two groups: 1) the treatment of acute attacks; and 2) to prevent and heat ment of chronic asthma
For Immediate Attack
Adrenerglc Beta :. receptor simulated: Salbutamol (Asthalin, Bronkotab, Ventrolin) Terbutaline (Bricanyl), Adrenaline
Stimulation of the adrenergic beta-receptors in the lungs causes a relaxation of the bronchioles and opens the respiratory airways. Salbutamol and terbutaline are effective.
It is most commonly used drugs to produce dilation of narrowed airways in asthma. For acute attacks, and it is administered by inhalation (patient breathes medicine with deep inspiration with the nose pinched, training is essential for optimal performance). Two types of inhalers are available.
It has been tested “gold standard” for termination of acute asthma attack. However, because it interferes with the heart and it is now rarely used and its use should be avoided. For the same reason isoprenaline is not used today
Direct-Acting Drugs :. Theophylline, aminophylline, Deriphylline
Theophylline and its preparation, aminophylline, cause dilated bronchioles direct action. aminophylline containing theophylline and ethylenediamine to solve agent, is very often used to provide relief of acute asthma attack. In this situation, aminophylline can be found in the well of the diluted solution intravenously. Theophylline is also given orally in combination with ephedrine and other drugs, to prevent recurrent asthma attacks . These are discussed at the end of this section. Theophylline is more effective when given at night to prevent the occurrence of nocturnal attacks
Dosage :. The average oral dose of theophylline is 100 to 200 mg given 3 4 times per day. This is generally not tolerated by most patients. To provide immediate relief, aminophylline, containing 250 mg of theophylline, is diluted in 20 ml of of5% glucose and injected intravenously, slowly, over a period of 5 to 10 minutes. Deriphylline irritation less stomach and is better absorbed
effects and precautions :. Theophylline is irregularly absorbed and effective dose oral irritation of the gastrointestinal tract. So it should never be taken on an empty stomach. The most common side effects are nausea, loss of appetite and vomiting. A very quick vein of raw theophylline may cause a sudden drop in blood pressure and irregular heart beat.
