bronchodilator

 [brong″ko-di-la´tor]
1. expanding the lumina of the bronchi.
2. an agent that does this. Epinephrine is one of the most powerful bronchodilators and can be administered by injection or by aerosol. Isoproterenol (Isuprel) affects the bronchi by relieving bronchospasm through its action on smooth muscle. It is one of the most widely used aerosol bronchodilators. Other drugs used to enlarge the lumen of the bronchi and thereby facilitate breathing and removal of secretions include isoetharine, atropine, and aminophylline.

bron·cho·di·la·tor

(brong'kō-dī-lā'ter, -tōr),
1. Causing an increase in caliber of a bronchus or bronchial tube.
2. An agent that possesses this power (for example, epinephrine, albuterol).

bronchodilator

(brŏng′kō-dī-lā′tər, -dĭ-, -dī′lā-)
n.
A drug that widens the air passages of the lungs and eases breathing by relaxing bronchial smooth muscle.

bronchodilator

Any agent that dilates the lumina of the upper airways to increase airflow, which is administered to wheezing patients.
 
Types
• Short-acting beta2 agonists—Inhaled agents with an early onset of action (e.g., salbutamol, which last up to 6 hours).
• Long-acting beta2 agonists—Oral agents that last up to 12 hours (e.g., salmeterol, formoterol).
• Anticholinergic—Prolonged action, lasting up to 24 hours (e.g., tiotropium); used for COPD.
• Theophylline—Long-acting; used to prevent asthma attacks.

Each participant in the second group was advised to take a specific inhaled dose of the steroid beclomethasone daily, regardless of symptoms, plus the rescue bronchodilator as needed in response to symptoms, as has been the standard recommendation for almost 30 years by the Global Initiative for Asthma guidelines.
Sulfating agents are used as preservatives for food and are also used as antioxidants for bronchodilator solutions to prevent degradation and inactivation.
Both initially had cough and dyspnea on exertion; their illness initially was misdiagnosed, and they were unsuccessfully treated with steroids and bronchodilators. In each case, a diagnosis of work-related obliterative bronchiolitis was made on the basis of lung function testing showing obstruction and hyperinflation, supportive HRCT and lung biopsy findings, and the temporal relationship between symptom onset and work exposure.
Conclusion: Pre bronchodilator criteria for detection of airflow obstruction overestimate the diagnosis of airflow obstruction and by using post bronchodilator criteria for airway obstruction on spirometry, decreases this over diagnosis of the condition.
However, the lack of an association between orofacial clefts and bronchodilators among those women who also used an anti-inflammatory drug suggests that perhaps women on polytherapy had more optimum treatment and therefore better control.
* Ask your doctor whether an inhaled corticosteroid and long-acting beta-agonist bronchodilator would be preferable to an inhaled anticholinergic.
Thus, in this patient, the practicing clinician can decide to treat the patient with a long-acting bronchodilator or a combination of inhaled corticosteroids and long-acting beta-2 agonists.
The children with both pre- and postnatal exposure had 15% more wheezing, 16% more rhinitis, 7% more use of cough medicine, 8% more use of bronchodilators, and suffered from 30% more crying and 27% more irritability than children with no tobacco exposure.
Bronchodilators are used as first-line agents for the symptomatic treatment of patients with COPD.
A low dose of terbutaline (a bronchodilator) at bedtime appears to prevent a drop in blood glucose during the night in patients with aggressively treated type 1 diabetes [Diabetes Care, December).
