Pregnancy Category: C
Used as a bronchodilator to control and prevent reversible airway obstruction caused by asthma or COPD. Inhalation: Used as a quick-relief agent for acute bronchospasm and for prevention of exercise-induced bronchospasm. Oral: Used as a long-term control agent in patients with chronic/persistent bronchospasm.
Binds to beta2-adrenergic receptors in airway smooth muscle, leading to activation of adenyl cyclase and increased levels of cyclic-3′, 5′-adenosine monophosphate (cAMP). Increases in cAMP activate kinases, which inhibit the phosphorylation of myosin and decrease intracellular calcium. Decreased intracellular calcium relaxes smooth muscle airways.
Relaxation of airway smooth muscle with subsequent bronchodilation.
Relatively selective for beta2 (pulmonary) receptors.
Absorption: Well absorbed after oral administration but rapidly undergoes extensive metabolism.
Distribution: Small amounts appear in breast milk.
Metabolism and Excretion: Extensively metabolized by the liver and other tissues.
Half-life: Oral 2.7–5 hr; Inhalation: 3.8 hr.

- Assess lung sounds, pulse, and BP before administration and during peak of medication. Note amount, color, and character of sputum produced.
- Monitor pulmonary function tests before initiating therapy and periodically during therapy.
- Observe for paradoxical bronchospasm (wheezing). If condition occurs, withhold medication and notify health care professional immediately.
- Lab Test Considerations: May cause transient ↓ in serum potassium concentrations with nebulization or higher-than-recommended doses.
Potential Nursing DiagnosesIneffective airway clearance (Indications)
- Oral: Administer oral medication with meals to minimize gastric irritation.
- Extended-release tablets should be swallowed whole; do not break, crush, or chew.
- Inhalation: Shake inhaler well, and allow at least 1 min between inhalations of aerosol medication. Prime the inhaler before first use by releasing 4 test sprays into the air away from the face. Pediatric: Use spacer for children < 8 yr of age.
- For nebulization or IPPB, the 0.5-, 0.83-, 1-, and 2-mg/mL solutions do not require dilution before administration. The 5 mg/mL (0.5%) solution must be diluted with 1–2.5 mL of 0.9% NaCl for inhalation. Diluted solutions are stable for 24 hr at room temperature or 48 hr if refrigerated.
- For nebulizer, compressed air or oxygen flow should be 6–10 L/min; a single treatment of 3 mL lasts about 10 min.
- IPPB usually lasts 5–20 min.
- Instruct patient to take albuterol as directed. If on a scheduled dosing regimen, take missed dose as soon as remembered, spacing remaining doses at regular intervals. Do not double doses or increase the dose or frequency of doses. Caution patient not to exceed recommended dose; may cause adverse effects, paradoxical bronchospasm (more likely with first dose from new canister), or loss of effectiveness of medication.
- Instruct patient to contact health care professional immediately if shortness of breath is not relieved by medication or is accompanied by diaphoresis, dizziness, palpitations, or chest pain.
- Instruct patient to prime unit with 4 sprays before using and to discard cannister after 200 sprays. Actuators should not be changed among products.
- Inform patient that these products contain hydrofluoralkane (HFA) and the propellant and are described as non-CFC or CFC-free (contain no chlorofluorocarbons).
- Instruct patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult health care professional before taking any OTC medications or alcoholic beverages concurrently with this therapy. Caution patient also to avoid smoking and other respiratory irritants.
- Inform patient that albuterol may cause an unusual or bad taste.
- Inhalation: Instruct patient in the proper use of the metered-dose inhaler or nebulizer (see ).
- Advise patients to use albuterol first if using other inhalation medications and allow 5 min to elapse before administering other inhalant medications unless otherwise directed.
- Advise patient to rinse mouth with water after each inhalation dose to minimize dry mouth and clean the mouthpiece with water at least once a week.
- Instruct patient to notify health care professional if there is no response to the usual dose or if contents of one canister are used in less than 2 wk. Asthma and treatment regimen should be re-evaluated and corticosteroids should be considered. Need for increased use to treat symptoms indicates decrease in asthma control and need to reevaluate patient’s therapy.
- Pediatric: Caution adolescents and their parents about overuse of inhalers, which can cause heart damage and life-threatening arrhythmias.
- Prevention or relief of bronchospasm.
