  2. Long Acting Beta Agonist


    salmeterol (Serevent)
    • *Action
    • Bronchodilation; relaxing bronchial smooth muscle by binding to the pulmonary beta 2 receptors
    • Slow onset with long duration.
    • Used to PREVENT asthma attack.

    • *Assessments
    • Monitor for hypersensitivity reaction (rash, face, swelling).

    • *Interventions

  3. Cholinergic Antagonist

    ipratopium (Atrovent), tiotropium (Spiriva)
    • *Action
    • Bronchodilation; inhibiting parasympathetic nervous system, allowing SNS to dominate.
    • Resuce & asthma attack prevention.

    • *Assessments
    • Assess degree of dyspnea before administering & at peak (1-2hr).
    • Assess for allergy to atropine.

    • *Interventions

    NOT REALLY USED ANYMORE
    • *Action
    • CNS stimulant causing bronchodilation.
    • Used for long-term asthma prevention.

    • *Assessments
    • Monitor chest pain & ECG changes if hx of CVD.
    • Monitor drug levels routinely.
    • Watch for S/S of toxicity (anorexia, N/V/D, confusion).

    • *Interventions
    • Administer around the clock to maintain blood levels.
    • Administer oral dose with food or full glass of water.
    • Higher doses are required at start of therapy.

    prednisone (Deltasone, Solu-Medrol, Decadron) -> Systemic IV; only used short-term for acute asthma exacerbation.
    • *Action
    • Inhaled steriods disrupt inflammatory mediators preventing asthma attacks caused by inflammation or allergies.
    • Decrease inflammatory & immune responses.
    • Preventing manifestations of asthma.

    • *Assessments
    • S/S of local infections especially yeast infections.

    • *Interventions
    • Slow onset of action, use drug daily even when no symptoms.

  6. Mast Cell Stabilizer

    cromolyn (Intal), nedocromil (Tilade)
    • *Action
    • Stabilizes membranes of mast cells and prevents release of inflammatory mediators (histamine).
    • Preventing asthma attack triggered by inflammation or allergies.

    • *Assessments

    • *Interventions
    • Taken daily by inhalation.
    • NOT USED DURING ASTHAM ATTTACK

    • Prevents asthma attack triggered by inflammation or allergens.

    • *Assessments
    • Assess allergy symptoms (rash, urticarial).
