Bronchodilators, short term

Short-term bronchodilators are beta2-agonists that act to relieve bronchospasm by elevating cyclic adenosine monophosphate (AMP) in cells. They are used for acute relief of bronchospasm and for prophylaxis, especially prior to exercise.

Albuterol (Proventil, Ventolin, Proair)

Albuterol is a beta-agonist for bronchospasm refractory to epinephrine. It stimulates adenyl cyclase to convert ATP to cAMP and causes bronchodilation. It relaxes bronchial smooth muscle by action on beta2-receptors, with little effect on cardiac muscle contractility. It may decrease mediator release from mast cells and basophils and inhibit airway microvascular leakage.

The frequency may be increased. Institute a regular schedule in patients on anticholinergic drugs who remain symptomatic.

The following list of albuterol products are for acute relief of asthma in various stages. It is most commonly used alone in intermittent asthma or as prophylaxis, especially before exercise.

It is available as a tablet at 2 or 4 mg, extended-release tablets are 4 or 8 mg, syrup at 2 mg/5 mL, hydrofluoroalkane (HFA) MDI 90 mcg per actuation, and inhalation solution for nebulization 0.083% (0.83 mg/mL, 2.5 mg/3 mL) or 0.5% (5 mg/mL).

Pirbuterol (Maxair)

Pirbuterol directly acts on beta 2-receptors to relax bronchial smooth muscle, relieving bronchospasm and reducing airway resistance.

Levalbuterol (Xopenex)

Levalbuterol is used for acute relief of asthma in various stages. It is used alone more commonly in intermittent asthma or as prophylaxis for asthma, especially before exercise.
