Albuterol Overview
- Generic name: Albuterol
- Trade names: ProAir HFA, ProAir RespiClick, Proventil, Proventil HFA, ReliOn, Salbutamol
Classification and Mechanism
- Classification: Adrenergic B2-Adrenergic, sympathomimetic, bronchodilator
- Mechanism of action: Causes bronchodilation by stimulating B2 receptors, increasing cAMP levels that relax smooth muscle; effects include CNS and cardiac stimulation, enhanced diuresis, and gastric acid secretion.
Dosage and Administration
- Standard dose: 2 puffs (180 mcg) via inhalation
- Routes of administration: Inhalation (INH), orally (po), nebulization (Neb/IPPB)
- Timing: Typically taken q4-6 hours as needed
- Normal dosage range: 180 mcg to 32 mg
Pharmacokinetics
- Onset of action:
- PO: 30 minutes
- INH: 5-15 minutes
- Peak effect:
- PO: 2-3 hours
- INH: 1.5-2 hours
- Duration of action:
- PO: 4-6 hours
- INH: 2-6 hours
Therapeutic Uses
- Indicated for prevention of:
- Exercise-induced asthma
- Acute bronchospasm
- Bronchitis, emphysema, bronchiectasis
- Unlabeled uses include:
- Hyperkalemia in dialysis patients
- Chronic Obstructive Pulmonary Disease (COPD)
Laboratory Considerations
- Notable lab alteration: Decreases potassium levels
Nursing Implications
-
Pre-administration assessment criteria:
- Evaluate respiratory function (vital capacity, ABGs)
- Monitor lung sounds, heart rate, blood pressure
- Assess patient's self-medication capability
- Confirm absence of allergic reactions or signs of paradoxical bronchospasm
-
Hold administration if:
- Paradoxical bronchospasm or hypokalemia is evident
-
Post-administration expectations:
- Absence of dyspnea or wheezing
- Improved airway exchange and ABGs
Side Effects and Adverse Reactions
- CNS: Tremors, anxiety, insomnia, headache, hallucinations
- Cardiovascular: Palpitations, tachycardia, angina, dysrhythmias
- EENT: Dry nose, throat irritation
- GI: Heartburn, nausea, vomiting
- Miscellaneous: Flushing, sweating, hypokalemia, muscle cramps, paradoxical bronchospasm
Patient Education
- Emphasize adherence to prescribed use and management of missed doses
- Demonstrate inhaler technique, including shaking and priming
- Warn against using near heat or flames and avoid eye contact with aerosol
- Instruct to wash inhaler regularly and discard after labeled uses are depleted
- Advise limiting caffeine intake to reduce stimulation risk
Drug Interactions
- Increased effects with:
- CNS stimulants, potassium-losing diuretics, digoxin, other adrenergics, tricyclics, MAOIs
- Decreased effects when used with:
- Beta-blockers
- Possible severe hypotension when combined with oxytocics
Contraindications and Precautions
- Contraindications: Hypersensitivity to sympathomimetics
- Precautions for use in patients with:
- Pregnancy, cardiac/renal issues, hyperthyroidism, diabetes, hypertension
- Age-related considerations for pediatric asthma management
