interventions: can cause tachycardia from excessive use, pt has to inhale med. contraindicated use in cardiac pts.
What are Xanthines?
short acting theophylline (aminophylline),action: bronchodilation, decreases vascular permeability, stregthens contractions of diaphragm,increases CO, peripheral vasodilation, stimulates CNS, intervention: monitor serum drug levels closley,use cautiously in cardiac pts, peptic ulcers, and acute gastritis.
what are corticosteriods?
anti inflammatory agents, prednisolone (cotolone), prednisone, inhalers: budesonide, fluticasone, action: suppress inflammation, and increases sensiblity of Beta2 receptors improving actions of bronchiodilators, Interventions: adm. before bronchiodilators, use cautiously in pts with CHF, peptic ulcers, thrombolitic disease
what are anticholinergics?
Ipratropium (atrovent), action: block the action of acetylocholine in bronchial muscle, intervention: taken by inhalation, use cautiously in pts in narrow angle glaucoma, prostatic hypertrophy.
