What drugs are used to treat asthmatic bronchitis?
These drugs have the ability to dilate (relax) the bronchioles (smooth muscle of the airways) and allow better airflow through the lungs. Steroids: beclomethasone, budesonide and fluticasone Both oral and inhaled corticosteroids are used to treat asthmatic bronchitis. They may reduce swelling in the airways.
How do anticholinergic bronchodilators work in asthma?
In asthma, cholinergic nerves going to the lungs cause narrowing of the airways by stimulating muscles surrounding the airways to contract. The "anticholinergic" effect of anticholinergic bronchodilators blocks the effect of cholinergic nerves, causing the muscles to relax and airways to dilate.
Which bronchodilators are used to treat bronchospasm?
The bronchodilators listed in this article are used for managing bronchospasm due to asthma, reactive airway disease, and exercise-induced asthma. Short-acting beta-adrenergic bronchodilators and ipratropium work quickly and are used for acute management of asthma episodes.
Which is the best bronchodilator for asthma with cardiac side effects?
They are the fastest acting bronchodilators when inhaled. Though adrenaline and isoprenaline are effective bronchodilators, it is the selective β2 agonists that are now used in asthma to minimize cardiac side effects. A highly selective β2 agonist; cardiac side effects are less prominent.
Which drugs dilate the walls of the bronchi in the treatment of asthma a corticosteroids B anti inflammatories C decongestants D bronchodilators?
Bronchodilators are medications that open (dilate) the airways (bronchial tubes) of the lung by relaxing bronchial muscles and allow people who have difficulty breathing to breath better. Bronchodilators are used for treating: Asthma.
What disease is characterized by bronchial dilation that leads to secondary infection?
Bronchiectasis is defined as abnormal chronic dilatation of one or more bronchi. This structural abnormality predisposes the bronchi to bacterial infection. The most common symptoms are chronic cough and sputum production.

Bronchodilators: These medicines relax airways. You inhale a mist containing bronchodilators that help you breathe easier.
What hormone agent is effective in reducing inflammation?
The use of glucocorticoids to reduce inflammatory responses is largely based on the knowledge of the physiological action of the endogenous glucocorticoid, cortisol. Corticotropin‐releasing hormone (CRH) is a neuropeptide released from the hypothalamic–pituitary–adrenal axis of the central nervous system.
What causes bronchial dilation?
Bronchiectasis is an irreversible widening (dilation) of portions of the breathing tubes or airways (bronchi) resulting from damage to the airway wall. The most common cause is severe or repeated respiratory infections, often in people who have an underlying problem with their lungs or immune system.
What is the medical term for dilation of bronchi?
The term “bronchiectasis” is used to describe the abnormal dilation of bronchi, and, by definition, it is reserved to describe an irreversible process. Bronchiectasis may be the cause of recurrent infections or the consequence thereof.
What type of medication is used to open or relax the bronchial tubes and relieve shortness of breath?
Bronchodilators are a type of medication that make breathing easier by relaxing the muscles in the lungs and widening the airways (bronchi). They're often used to treat long-term conditions where the airways may become narrow and inflamed, such as: asthma, a common lung condition caused by inflammation of the airways.

What is a metered dose inhaler?
A ‘spacer’ (chamber interposed between the inhaler and the patient’s mouth) can be used to improve drug delivery. Nebulizers produce a mist of the drug solution generated by pressurized air or oxygen which can be inhaled through a mouth piece, face mask or in a tent. Metered dose inhalers are convenient handheld devices which can be carried along, while nebulizers are used at patient’s bed side. Nebulizers are preferred for severe episodes of asthma as well as for children and elderly. More than one drug can be nebulized simultaneously.
What are the antagonists of LTC4/D4?
Since it was realized that cystenyl leukotrienes (LTC4/D4) are important mediators of bronchial asthma, efforts were made to develop their antagonists and synthesis inhibitors . Two cysLT1 receptor antagonists montelukast and zafirlukast are available.
How is theophylline absorbed?
Theophylline is well absorbed orally; rectal absorption from suppositories is erratic. It is distributed in all tissues—crosses placenta and is secreted in milk, (V 0.5 l/kg), 50% plasma protein bound and extensively metabolized in liver by demethylation and oxidation. Only 10% is excreted unchanged in urine. Its elimination rate varies considerably with age. At therapeutic concentrations, the t½ in adults is 7–12 hours. Children eliminate it much faster (t½ 3–5 hours) and elderly more slowly. In premature infants also the t½ is prolonged (24–36 hours). There are marked interindividual variations in plasma concentrations attained with same dose.
What are the different classes of antiasthma drugs?
Four classes of antiasthma drugs, viz. β2 agonists, anticholinergics, cromoglycate and glucocorticoids are available for inhalational use. They are aimed at delivering the drug to the site of action so that lower dose is needed and systemic side effects are minimized. Most asthma patients are now maintained on inhaled medication only. Aerosols are of two types:
Is theophylline a first line drug?
Theophylline and its compounds have been extensively used in asthma, but are not considered first line drugs any more. They are used more often in COPD. Theophylline is one of the three naturally occurring methylated xanthine alkaloids caffeine, theophylline and theobromine. The chemical relation between the three is depicted below:

Oral theophylline comes in many forms, from short-acting tablets and syrups to longer-acting sustained release capsules and tablets. Theophylline is used mainly for prevention of asthma.
What are the two classes of asthma drugs?
(See also Asthma .) Therapy is based on two classes of drugs: Anti-inflammatory drugs. Bronchodilators. Anti-inflammatory drugs suppress the inflammation that narrows the airways.
What is omalizumab used for?
Omalizumab is used in people with asthma who also have severe allergies and high levels of IgE in their blood. Omalizumab prevents IgE from binding to mast cells and thus prevents the release of inflammatory chemicals that can narrow the airways. It can decrease requirements for oral corticosteroids and help relieve symptoms. The drug is injected subcutaneously every 2 to 4 weeks.
How often is reslizumab given?
Reslizumab reduces the number of asthma attacks and decreases asthma symptoms. It is given intravenously every 4 weeks. Benralizumab and dupilumab may be given in addition to other asthma drugs for people who have a lot of eosinophils (a type of white blood cell) in their bloodstream.
How does theophylline affect the body?
When first taking theophylline, a person who has asthma may feel slightly jittery and may develop headaches. These side effects usually disappear as the body adjusts to the drug. Larger doses may cause a rapid heartbeat, nausea, or palpitations. A person may also experience insomnia, agitation, vomiting, and seizures. Occurrence of these side effects is one of the reasons that theophylline is used less often than other drugs.

People with high blood pressure, diabetes, thyroid disease, or heart disease shouldn't take OTC asthma drugs like Primatene Mist and Bronkaid.
What causes shortness of breath and wheezing?
Asthma is a condition in which hyperreactive airways constrict and result in symptoms like wheezing, coughing, and shortness of breath. Causes of asthma include genetics, environmental factors, personal history of allergies, and other factors . Asthma is diagnosed by a physician based on a patient's family history and results from lung function tests and other exams. Inhaled corticosteroids (ICS) and long-acting bronchodilators (LABAs) are used in the treatment of asthma. Generally, the prognosis for a patient with asthma is good. Exposure to allergens found on farms may protect against asthma symptoms.
