Bronchospasm or a bronchial spasm is a sudden constriction of the muscles in the walls of the bronchioles. It is caused by the release ( degranulation ) of substances from mast cells or basophils under the influence of anaphylatoxins .
In April 2020, the FDA approved the first generic of Proventil HFA (albuterol sulfate) metered dose inhaler, 90 μg per inhalation, for the treatment or prevention of bronchospasm in patients four years of age and older who have reversible obstructive airway disease, as well as the prevention of exercise-induced bronchospasm in this age group.

General treatment principles are removal from exposure, protection of the airway (i.e., preemptive intubation), and treatment of hypoxemia. Concomitant airway injury with acute bronchospasm often warrants treatment with bronchodilators because of the airway obstruction.
Onset of action for SAMAs is typically between 30 and 60 minutes, making these drugs less efficacious in treating acute asthma attacks and bronchospasm. [9] Most common side effects for these drugs may include dry mouth, headache, urinary tract infection, and bronchitis.
Analgesic medications, oxygen, humidification, and ventilator support currently constitute standard therapy. In fact, mechanical ventilation remains the therapeutic mainstay for acute inhalation injury. [36] [37] The cornerstone of treatment is to keep the PaO2 > 60 mmHg (8.0 kPa), without causing injury to the lungs with excessive O2 or ...
Salmeterol is a long-acting β 2 adrenergic receptor agonist (LABA) used in the treatment and prevention of asthma symptoms and control of chronic obstructive pulmonary disease (COPD) symptoms. [2] Symptoms of bronchospasm include shortness of breath, wheezing, coughing and chest tightness.
Mometasone/formoterol, sold under the brand name Dulera among others, is a fixed-dose combination medication used in the long-term treatment of asthma. [1] It contains mometasone a steroid and formoterol a long-acting beta agonist. [1] It is only recommended in those for whom an inhaled steroid is not sufficient. [1] It is used by inhalation. [1]
Mast cell stabilizers are given as prophylactic treatment to prevent exacerbation of asthmatic symptoms. [22] For asthma maintenance therapy, mast cell stabilizers are taken by inhalation. [2] Common adverse effects of Mast cell stabilizers include mouth dryness, cough, throat irritation, nasal congestion and bronchospasm. [23]
