(1.1) • Prevention of exercise-induced bronchospasm in patients 4 years of age and older. (1.2) DOSAGE AND ADMINISTRATION For oral inhalation only • Treatment or prevention of bronchospasm in adults and children 4 years of age and older: 2 inhalations every 4 to 6 hours. In some patients, one inhalation every 4 hours may be sufficient. (2.1) • Prevention of exercise-induced bronchospasm in adults and children 4 years of age and older: 2 inhalations 15 to 30 minutes before exercise. (2.2) • Priming information: Prime PROAIR HFA before using for the first time, or when the inhaler has not been used for more than 2 weeks. To prime PROAIR HFA, re- lease 3 sprays into the air away from the face. Shake well before each spray. (2.3) • Cleaning information: At least once a week, wash the actuator with warm water, shake off excess, and air dry thoroughly. (2.3) • PROAIR HFA inhaler should be discarded when the dose counter displays 0 or after the expiration date on the product, whichever comes first. (2.3) DOSAGE FORMS AND STRENGTHS Inhalation Aerosol: Each actuation delivers 108 mcg of albuterol sulfate from the actuator mouthpiece (equivalent to 90 mcg of albuterol base). Supplied in 8.5-g can- ister containing 200 actuations. (3) CONTRAINDICATIONS Hypersensitivity to albuterol and any other PROAIR HFA Inhalation Aerosol Compo- nents. (4) WARNINGS AND PRECAUTIONS • Life-threatening paradoxical bronchospasm may occur. Discontinue PROAIR HFA immediately and treat with alternative therapy. (5.1) • Need for more doses of PROAIR HFA than usual may be a sign of deterioration of asthma and requires reevaluation of treatment. (5.2) • PROAIR HFA is not a substitute for corticosteroids. (5.3) • Cardiovascular effects may occur. Use with caution in patients sensitive to sympatho- mimetic drugs and patients with cardiovascular or convulsive disorders. (5.4, 5.7) • Excessive use may be fatal. Do not exceed recommended dose. (5.5) • Immediate hypersensitivity reactions may occur. Discontinue PROAIR HFA imme- diately. (5.6) • Hypokalemia and changes in blood glucose may occur. (5.7, 5.8) ADVERSE REACTIONS Most common adverse reactions (3.0% and >placebo) are headache, tachycardia, pain, dizziness, pharyngitis, and rhinitis. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Teva Respiratory, LLC at 1-888-482-9522 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. DRUG INTERACTIONS • Other short-acting sympathomimetic aerosol bronchodilators and adrenergic drugs: May potentiate effect. (7) • Beta-blockers: May decrease effectiveness of PROAIR HFA and produce severe bronchospasm. Patients with asthma should not normally be treated with beta- blockers. (7.1) • Diuretics, or non-potassium sparing diuretics: May potentiate hypokalemia or ECG changes. Consider monitoring potassium levels. (7.2) • Digoxin: May decrease serum digoxin levels. Consider monitoring digoxin lev- els. (7.3) • Monoamine oxidase (MAO) inhibitors and tricyclic antidepressants: May potentiate effect of albuterol on the cardiovascular system. Consider alternative therapy in patients taking MAOs or tricyclic antidepressants. (7.4) See 17 for PATIENT COUNSELING INFORMATION and FDA-approved patient labeling.

In this way, the patient can be sure to always know the correct number of remaining doses. Never attach a canister of medication from any other inhaler to the PROAIR HFA actuator and never attach the PROAIR HFA canister to an actuator from any other inhaler.

12.1 Mechanism of ActionAlbuterolsulfate isabeta2-adrenergicagonist.Thepharmacologiceffectsof

albuterolsulfateareattributabletoactivationofbeta2-adrenergicreceptorsonairwaysmoothmuscle.Activationofbeta2-adrenergicreceptors leads to theactivationofadenylcyclaseand toan increase in the intracellularconcentrationofcyclic-3’,5’- adenosinemonophosphate(cyclicAMP).ThisincreaseofcyclicAMPisassociatedwiththeactivationofproteinkinaseA,whichinturninhibitsthephosphorylationofmyosin and lowers intracellular ionic calcium concentrations, resulting inmusclerelaxation.Albuterolrelaxesthesmoothmuscleofallairways,fromthetracheatotheterminalbronchioles.Albuterolactsasafunctionalantagonisttorelaxtheairwayirrespectiveofthespasmogeninvolved,thusprotectingagainstallbronchoconstric-tor challenges. Increased cyclic AMP concentrations are also associatedwith theinhibitionofreleaseofmediatorsfrommastcellsintheairway.Whileitisrecognizedthat beta2-adrenergicreceptorsarethepredominantreceptorsonbronchialsmoothmuscle,dataindicatethattherearebeta-receptorsinthehumanheart,10%to50%ofwhicharecardiacbeta2-adrenergicreceptors.Theprecisefunctionoftheserecep-tors has not been established [see Warnings and Precautions (5.4)].

Albuterolhasbeenshowninmostcontrolledclinicaltrialstohavemoreeffecton the respiratory tract, in the formof bronchial smoothmuscle relaxation, thanisoproterenol at comparable doses while producing fewer cardiovascular effects.However,inhaledalbuterol,likeotherbeta-adrenergicagonistdrugs,canproduceasignificantcardiovasculareffectinsomepatients,asmeasuredbypulserate,bloodpressure,symptoms,and/orelectrocardiographicchanges[see Warnings and Pre-cautions (5.4)].

12.2 PharmacokineticsThe systemic levels of albuterol are low after inhalation of recommended

doses.Inacrossoverstudyconductedinhealthymaleandfemalevolunteers,highcumulativedosesofPROAIRHFAInhalationAerosol(1,080mcgofalbuterolbaseadministeredoveronehour)yieldedmeanpeakplasmaconcentrations(Cmax)andsystemic exposure (AUCinf) of approximately 4,100 pg/mL and 28,426 pg/mL*hr,respectivelycomparedtoapproximately3,900pg/mLand28,395pg/mL*hr,respec-tively following the same dose of an active HFA-134a albuterol inhaler compara-tor.The terminalplasmahalf-lifeofalbuteroldeliveredbyPROAIRHFA InhalationAerosolwasapproximately6hours.Comparisonofthepharmacokineticparametersdemonstratednodifferencesbetweentheproducts.

ThepharmacokineticprofileofPROAIRHFAInhalationAerosolwasevaluatedinatwo-waycross-overstudyin11healthypediatricvolunteers,4to11yearsofage.AsingledoseadministrationofPROAIRHFAInhalationAerosol(180mcgalbuterolbase)yieldedaleastsquaremean(SE)CmaxandAUC0-∞of1,100(1.18)pg/mLand5,120(1.15)pg/mL*hr,respectively.Theleastsquaremean(SE)terminalplasmahalf-lifeofalbuteroldeliveredbyPROAIRHFAInhalationAerosolwas166(7.8)minutes.

Metabolism and Elimination:Informationavailableinthepublishedliteraturesuggests that the primary enzyme responsible for themetabolismof albuterol inhumans isSULTIA3 (sulfotransferase).When racemic albuterolwas administeredeitherintravenouslyorviainhalationafteroralcharcoaladministration,therewasa3-to4-folddifferenceintheareaundertheconcentration-timecurvesbetweenthe(R)-and(S)-albuterolenantiomers,with(S)-albuterolconcentrationsbeingconsis-tentlyhigher.However,withoutcharcoalpretreatment,aftereitheroralorinhalationadministrationthedifferenceswere8-to24-fold,suggestingthatthe(R)-albuterolispreferentiallymetabolizedinthegastrointestinaltract,presumablybySULTIA3.
