Common Drugs Adrenergic/Bronchodilators

Epinephrine (Adrenalin)
Definition
oInjected subcutaneously
oEmergency room, Given IM
oCaution; excess causes cardiac stimulation
Term
Common Drugs Adrenergic/Bronchodilators

Albuterol (Proventil)
Definition
-1st treatment of choice in acute asthma attack
-Inhaled (nebulizer or aerosol)
-Act more selectively on beta 2 receptors causing less cardiac stimulation
-Usually self administered by multi-dose inhaler (MDI)
-May be prescribed every 4 – 6 hours
-If overused can lose their bronchodilation effects
Term

Drug Selection & Administration Guidelines
Definition
-Selective, short-acting adrenergic agonist is initial drug of choice for acute bronchospasm
-Direct action of inhaled medications on airways can be given in smaller doses with fewer adverse effects than oral or parenteral medications
-Inhaled corticosteroids are used early in disease process when inflammation is established as major asthmatic component
-In chronic disorders, inhaled corticosteroids should be taken on regular schedule using lowest dose required to control symptoms
-Multidrug regimens offer advantage of smaller doses of each medication, which can decrease adverse effects, allow dosage increase as needed in exacerbations
-Drug dosing must be individualized to attain most therapeutic effects with fewest adverse effects
Term
Patient teaching guidelines

Education about disease and all medications

-Use MDI accurately
-Avoid airway irritants
-Avoid excess caffeine
-Influenza vaccine yearly & pneumococcal vaccine once
-Inhalers
-Shake well prior to use
-Exhale to end of a normal breath
-Insert inhaler into mouth form a tight seal around mouthpiece
-While pressing down take slow deep breath and hold breath approximately 10 seconds
-Rinse mouth with water after each use
-Rinse mouthpiece
-Wait 3-5 mins before taking 2nd dose
