Answer

Bronchodilators

Bronchodilators decrease muscle tone in both the small and large airways in the lungs, thereby increasing ventilation. They include subcutaneous medications, beta-adrenergic agents, methylxanthines, and anticholinergics.

Albuterol (Proventil, Ventolin)

Albuterol is a beta-agonist for bronchospasm refractory to epinephrine. It relaxes bronchial smooth muscle by action on beta-2 receptors, with little effect on cardiac muscle contractility. Most patients (even those with no measurable increase in expiratory flow) benefit from treatment. Inhaled beta-agonists initially are prescribed on an "as needed" basis. The frequency may be increased; institute a regular schedule in patients on anticholinergic drugs who are still symptomatic.

Albuterol is available as a liquid for nebulizer, metered-dose inhaler (MDI), and dry-powder inhaler.

Metaproterenol (Alupent)

Metaproterenol relaxes bronchial smooth muscle by action on beta-2 receptors, with little effect on cardiac muscle contractility. Most patients (even those with no measurable increase in expiratory flow) benefit from treatment. Inhaled beta-agonists initially are prescribed on an as-needed basis. The frequency may be increased; institute a regular schedule in patients on anticholinergic drugs who are still symptomatic.
