Pharmacotherapy
Step 1 - Very mild disease may be controlled with inhaled short-acting bronchodilator alone. These short acting agents include
There are two categories of antiasthma drugs: bronchodilators and anti-inflammatory agents. Bronchodilators reverse the bronchospasm of the immediate phase. While anti-inflammatory agents inhibit or prevent the inflammatory components of both phases. These two categories are not mutually exclusive: some drugs classified as bronchodilators also have some anti-inflammatory effect. The first step in treating the very mild disease may be controlled with short-acting bronchodilators, such as salbutamol or terbutaline alone. Salbutamol can be given by inhalation, so they can be delivered directly to the

These drugs are given by inhalation, and the duration of action is normally 8–12 hours, but the lipophilic side-chains extend this duration of action up to 24 hours. They are not used ‘as needed’ but are given regularly, twice daily, as adjunctive therapy in patients whose asthma is inadequately controlled by glucocorticoids. They are used to prevent bronchospasm (e.g. at night or with exercise) in patients requiring long-term bronchodilator therapy. Although, prolonged use may lead to receptor desensitisation or down-regulation.
Step 4 - Consider theophylline and leukotriene antagonists, as they exert a glucocorticoid sparing effect, one or other is added for patients with more severe asthma and/or the dose of inhaled glucocorticoid increased to the maximum recommended.
Theophylline and leukotriene antagonists, such as Montelukast, also exert a corticosteroid-sparing effect, but this is less reliable. One or the other is added as the fourth step for patients who remain symptomatic and/or the dose of inhaled corticosteroid increased to the maximum recommended. Theophylline is often formulated as aminophylline and is a methyl xanthine, which inhibits phosphodiesterase and blocks adenosine receptors, but has a narrow therapeutic window with unwanted effects including cardiac dysrhythmia, seizures and gastrointestinal disturbances. The drug is given intravenously by slow infusion for status
CURRENT MEDICATIONS: Lovastatin 20 mg po per day, Enalapril 20 mg po bid, Nitroglycerin 0.4 mg sub q prn for chest pain.
I would anticipate the physician ordering a bronchodilator like albuterol due to its rapid effectiveness in widening D.Q.’s airway. Additionally the physician could order an expectorant such as guaifenesin. Finally, a glucocorticoid, such as advair would most likely be prescribed to assist
When an asthmatic takes an inhaler “Albuterol sulfate”, the medication works by reducing the inflammation in the airway paths “bronchi and bronchioles” of the lungs, allowing the patient to breath without constriction or symptoms of asthma.

I have made no changes to Ms. Dahlberg's bronchodilator and inhaled corticosteroid use. She does have a prescription of prednisone at home, as she is well aware of her asthma exacerbation equivalents. She does have a history of steroid use psychosis and I advised her to initiate treatment at 40 mg per day. She should then seek further medical attention after initiating systemic steroids. She should also continue use of her current bronchodilators and inhaled corticosteroids.
Bronchiolitis is defined by the textbook as, “a diffuse, inflammatory obstruction in the small airways or bronchioles occurring most commonly in children” (Heuther & McCance, 2012). It is an acute inflammatory disease of the lower respiratory tract that occurs most commonly in infants and is caused by infection with seasonal viruses such as respiratory synctial virus (RSV) (Zorc & Hall, 2010). Bronchiolitis often results from an obstruction of the small airways. It is the leading cause of infant hospitalization in the United States (Zorc & Hall 2010) and is arguably the most common significant medical illness of childhood, with at least “1 in 7 normal infants developing symptomatic bronchiolitis in his or her first year of
Acute severe asthma previously called status asthmaticus is a life threatening medical condition characterized by bouts of repeated and worsening cough, wheezing, chest recession and inability to speak or drink that may result in acute respiratory failure and even death.1 These patients are also at risk for developing serious complications like aspiration pneumonia, pneumo-mediastinum, pneumothorax and hypoxic brain injury etc. 1Inhaled high dose short acting β2 agonists like salbutamol along with systemic steroids and supplemental oxygen are considered as first line treatment in all patients who
β receptor agonists are used in the treatment of asthma and COPD (chronic obstructive pulmonary disease) to relax the muscles in the air passages in the lungs. Salbutamol is a selective β2 adrenergic agonist, although this selectivity is relative and dose-dependent. This means that the selectivity is lost at high concentration and thus causing side-effects.
Theophylline is one example of xanthine that is usually used to treat bronchial asthma through relaxing the airways. However, this drug may cause severe adverse effects because of its level in the blood. Thus, it is important to teach patient about the use of theophylline. Teach a patient that theophylline can help him to breath easier, decrease wheeze and short of breath if taken exactly as prescribed. The nurse should also tell the patient take the drug of an empty stomach with a full 8-ounc glass of water. If patient has a severe GI problem such as GI upset, nausea, vomiting, heartburn when taking the drug on an empty stomach, the patient may take the drug with food. The patient should swallow all the enteric-coated or time-release capsules. Educating the patient about other common effect of the drug includes restlessness, nervousness, and difficulty in sleeping because of the need of the body to adjust to the usage of this drug. The patient should not take any other stimulant in order to reduce the effect of theophylline on CNS. The nurse should tell the patient that a headache will go away as the patient get used to the drug. However, the patient should notify his physician if the headache is getting worse. The patient should also report any vomiting, severe abdominal pain, tachycardia, confusion, unusual tiredness, muscle twitching, rash, or hives to the physician. There are many drug and food interaction, thus the patient should consult with the doctor about his diet while using theophylline. Additionally, the patient should consult his smoking habit and the use of any over-the-counter medication with the physician. Lastly, the patient should always tell any health care provider in his care about the use of theophylline and to keep the medication in a safe place (Karch, 2013, p.
Miss Brightman has been diasgnosed with asthma. Her current medication includes a short-acting beta2 agonist, when required, as well as a regularly inhaled corticosteroid. By referring to the BNF, this places Miss Brightman at step 2 on the asthma step therapy chart.
A type of bronchodilator, aminophylline is a type of muscle relaxation medicine that helps lungs and chest circulate oxygen better. It is used to treat and prevent wheezing, restricted breathing and shortness of breath. The medicine is usually prescribed to those with bronchitis, asthma and lung diseases. As this medication requires a prescription, it is very important for a user to follow the instructions prescribed and take only at the times and the amount prescribed by his or her physician. Aminophylline can be in the form of liquid syrup, a pill or a cream. How this drug works is by making the lungs less sensitive to any allergens or foreign substances that may be inhaled, thus causing the muscles to relax in the chest and lungs and opening up the air passages so that breathing can be easier. It also increases the contractions in the diaphragm which aids better breathing patterns.
Fluticasone propionate is a synthetic triflourinated corticosteroid that possess anti-inflammatory properties (RxList). This corticosteroid targets cells and mediators involved in inflammation, having an anti-inflammatory effect on the airways (RxList). Salmeterol Xinafoate is a long acting- beta agonist (LABA), targets the beta2-adrenoceptors that are present in the smooth muscle of the bronchioles (RxList). By targeting the beta2-adrenoceptors, intracellular adenyl cyclase is stimulated, which will lead to the production of more cyclic AMP. An increased level of cyclic AMP then leads to relaxation of the smooth muscle of bronchioles
It is important because many people do not know that asthma can potentially get worse from certain treatment options. Since asthma is a very common disease I believe that people should be aware of anything that can affect them and cause them harm. In the article The Local Side Effects of Inhaled Corticosteroids by Nicholas J. Roland, Rajiv K. Bhalla, and John Earis it states” Inhaled corticosteroids can lead to osteoporosis, bruising and thinning of the skin, subscapular cataracts, and even glaucoma.” (214). These side effects are things that people should be fully aware of and know that there is a chance that they might have to deal with side effects that could add other problems to them on top of asthma. In the article Current Treatment of Severe Asthma by S. Hashimoto and E. H. Bel states “Unfortunately the chronic use of oral corticosteroids is associated with serious side effects such as osteoporosis, diabetes, hypertension, and cataract formation” (697). Asthma treatments can have varying and concerning side effects that can drastically change a person’s life if they had these side
However, there is a multitude of effective ways to treat the disease that can increase the lifespan of an affected person. Constant vigilance for changes in one’s health is crucial. The main goals of treating the disease are clearing out mucus from the lungs and pancreas to prevent infection and providing necessary nutrition due to metabolic problems. A common treatment is the use of antibiotics, which aid in thinning excess mucus, lowering the risk of infection and increasing metabolism. Devices called nebulizers, which convert liquid medicine into a breathable “mist”, are used to easily move medication into the lungs through inhalation. Another common treatment is anti-inflammatories, which lessen swelling in your airways. To address digestive problems, people may take supplements of pancreatic digestive enzymes to increase the amount of absorbed nutrients within the body. In severe cases, surgical procedures may be applied to control the disease. Procedures include nasal polyp removal, where doctors remove any obstructive buildups in the nose, Endoscopy, where mucus is physically removed through endoscopes. In the most critical or life-threatening cases, a lung transplant may be performed to completely rid the patient of mucus buildup in the thoracic cavity. Unfortunately, due to the way mucus builds up in the lungs, a lung transplant requires both lungs to be
Indications: Salbutamol is a β2-agonist which causes bronchodilation by relaxing smooth muscles on the bronchiole. It is a reliever of bronchospasms in asthma, chronic obstructive pulmonary disorder (COPD) and emphysema. It provides short acting but instant bronchodilation to reverse airways obstruction. Inhalation of Salbutamol has an onset period of 5-15 minutes and lasts for 2-5 hours. Salbutamol is
