Introduction

Bronchodilator; relatively selective, short-acting β2-adrenergic agonist.j

Uses for Albuterol

Bronchospasm in Asthma

Symptomatic management or prevention of bronchospasm in patients with reversible, obstructive airway disease (e.g., asthma).132 139 154 181 241 249 255 282

Exercise-induced Bronchospasm

Prevention of exercise-induced bronchospasm.132 181 249

Chronic Obstructive Pulmonary Disease

Albuterol sulfate in fixed combination with ipratropium bromide: Symptomatic management of reversible bronchospasm associated with COPD in patients who continue to have evidence of bronchospasm despite regular use of an orally inhaled bronchodilator and who require a second bronchodilator.233 250 251 252

Albuterol sulfate: Symptomatic management of reversible bronchospasm associated with COPD† [off-label] when given on an as-needed or regular (e.g., 4 times daily) basis, either alone or concomitantly with other inhaled bronchodilators.181 206 251 266 267 268 269 Regular use of a selective, short-acting inhaled β2-adrenergic agonist (e.g., albuterol) in the management of COPD, in contrast to that in asthma, does not appear to be detrimental.206 247 250 251

Albuterol Dosage and Administration

General

Administration

Oral Inhalation

Metered-dose Aerosol Inhaler

Administer inhalation aerosol only with the actuator provided by the manufacturer.146 181 210 215

Shake inhaler well before use.146 181 210 215

Test-spray inhalation aerosol (3 times for ProAir HFA, 4 times for Ventolin HFA or Proventil HFA) into the air (away from the face) before first use and whenever the inhaler not used for prolonged periods (i.e., >2 weeks).181 215 237 248 282 Test spray Ventolin HFA aerosol inhaler whenever dropped.237

Avoid spraying aerosols into the eyes.181 210 215

Exhale slowly and completely and place the mouthpiece of the inhaler well into the mouth with the lips closed around it.210 215 Inhale slowly and deeply through the mouth.210 215 Actuate aerosol inhaler, hold breath for as long as possible, withdraw mouthpiece, and exhale slowly.210 215

Allow 1 minute to elapse between subsequent inhalations from aerosol inhaler.248 261

Clean the albuterol sulfate inhalation aerosol (ProAir HFA, Proventil HFA, Ventolin HFA) inhaler by removing the metal canister and running warm water through the plastic mouthpiece of the actuator for 30 seconds at least once a week.181 237 282 Dry thoroughly the mouthpiece before replacing the metal canister and mouthpiece cap.181 215 237 282 If the inhaler is to be used before it is completely dry, shake off excess water, replace the canister, and test the inhaler by spraying once (Ventolin HFA) or twice (ProAir HFA, Proventil HFA) away from the face before administering the dose.237 248 282 After such use, rewash the mouthpiece and allow to air dry.248 282 Proper cleaning of the albuterol sulfate inhaler (ProAir HFA, Proventil HFA, Ventolin HFA) mouthpiece will prevent medication build-up and blockage.181 237 248 282

Discard canister after the labeled number of actuations used.181 233 237 282

Nebulization

When administering via nebulization, use proper aseptic technique to avoid microbial contamination.114 241

For administration of albuterol sulfate solution for nebulization in single-use units, empty the entire contents of a single-use unit into the nebulizer reservoir and use immediately to avoid microbial contamination.241 242 243 255 256 263 283 For administration of single-use units of albuterol sulfate 0.5% concentrate solution for nebulization, empty the entire contents of the plastic vial into the nebulizer reservoir and add 2.5 mL of 0.9% sodium chloride solution into the nebulizer reservoir to provide a final volume of 3 mL.272 273

Attach the reservoir to the mouthpiece or face mask and to the compressor according to the manufacturer’s instructions.213 256 257 263 283

Place the mouthpiece of the nebulizer in the mouth or put on the nebulizer face mask and turn on the compressor.213 256 257 263 283 Breathe as calmly, deeply, and evenly as possible until the nebulizer stops producing mist (flow rate of nebulizer should be adjusted to provide the full dose over about 5–15 minutes).213 256 257 263 283

Clean the nebulizer after use according to the manufacturer’s instructions.213 241 244 245 246 256 257 263 283

Continue nebulization therapy as necessary to control recurrent bronchospasm.249 258 Optimum benefit is obtained when nebulization is used regularly.249 258

Acute or Worsening Asthma

Oral inhalation therapy is intended for the acute symptomatic relief of bronchospasm.188 189 190 191 192 249 If control of mild asthma deteriorates such that regular (i.e., exceeding 4 times daily) use of a short-acting β2-agonist becomes necessary, institute maintenance therapy (e.g., inhaled corticosteroids)188 189 191 249 and discontinue regular use of short-acting β2-agonists in such patients; instead, use short-acting β2-agonists only as a supplement for relief of acute asthma symptoms.188 189 190 191 192 194 197 249 Contact a clinician for reevaluation if control of mild asthma deteriorates.114 154 192 193 196

Failure to respond to a previously effective dosage of albuterol may indicate seriously worsening asthma.156 157 181 188 189 190 191 192 193 194 196 197 237 241 242 243 244 249 Reevaluate asthma therapy and institute alternative regimens or therapy.156 157 181 188 189 190 191 192 193 194 196 197 237 241 242 243 244 249 Discontinue and contact a clinician if decreased effectiveness occurs; do not increase the dose or frequency of administration.241

Excessive Doses

Possible fatalities associated with excessive use of inhaled sympathomimetic drugs.114 139 153 237 241 243 255 258 145 154 212 262 208 146 181 233 The safety of concomitant use of >8 inhalations per day of a short-acting β2-adrenergic agonist with a long-acting β2-agonist (e.g., salmeterol) oral inhalation therapy has not been established.192 287 (See Sympathomimetic Agents under Interactions.)

Paradoxical Bronchospasm

Possible life-threatening, acute paradoxical bronchospasm.181 241 255 Frequently occurs with the first use of a new canister or vial (oral inhalation aerosol),181 241 255 but also may occur with orally administered conventional or extended-release tablets.271 280

Discontinue therapy immediately if bronchoconstriction occurs and institute alternative therapy.271 280

Cardiovascular Effects

Possible clinically important cardiovascular effects, including cardiac arrhythmias (e.g., atrial fibrillation, supraventricular tachycardia, extrasystoles) , increased or decreased BP, and related symptoms.146 153 181

Cautious use recommended in patients with cardiovascular disorders (e.g., coronary insufficiency, cardiac arrhythmias), hypertension, and those with sensitivity to sympathomimetic amines.114 181 237 241 281 May require drug discontinuance.139 181

Sensitivity Reactions

Immediate hypersensitivity reactions (e.g., urticaria,139 146 153 181 angioedema,139 146 153 181 227 rash,100 139 146 153 181 bronchospasm,139 146 153 181 anaphylaxis,146 oropharyngeal edema)139 146 153 181 have been reported.139 153 181 Possible acute bronchospasm.181 185 186 (See Paradoxical Bronchospasm under Cautions.)

General Precautions

Nervous System Effects

Possible CNS stimulation and adverse nervous system effects.100 139 181

Cautious use recommended in patients with seizure disorders and in those with sensitivity to sympathomimetic amines.114 237

Metabolic Effects

Possible hypokalemia, which may increase risk of adverse cardiovascular effects.100 114 139 153 237 241 243 255 258 145 154 212 262 208 146 181 233 (See Cardiovascular Effects under Cautions.) Serum potassium decrease generally is transient and usually does not require supplementation.181 281

Diabetes mellitus or increased blood glucose in patients receiving orally inhaled or nebulized albuterol.112 181

Cautious use recommended in patients with diabetes mellitus or hyperthyroidism.181 237 241 281

GI Effects

Possible GI obstruction when extended-release tablets are used in patients with preexisting GI narrowing; cautious use recommended.154

Use of Fixed Combination

When used in fixed combination with other agents, consider the cautions, precautions, and contraindications associated with the concomitant agents.
