Antihistamine Agents Action: | Antihistamine agents block the effects of histamine within the respiratory system resulting in a decrease in nasal congestion, mucosal irritation, symptoms of the common cold, sinusitis, and conjunctivitis. |
Antihistamine Agents Indications: | respiratory allergic response, seasonal allergies, sedation, treatment of Parkinsonʼs disease, relief of cough, motion sickness, allergic conjunctivitis |
Antihistamine Agents Side effects: | sedation, dizziness, headache, blurred vision, fatigue, gastrointestinal distress, nausea, hypotension, other side effects are based on the specific drug and generation of antihistamine |
Antihistamine Agents Implications for PT: | Therapists should increase guarding during mobility to ensure patient safety. Antihistamines should not be used in the treatment of asthma due to the drying effect and subsequent thickening of secretions. |
Bronchodilator Agents Action: | Bronchodilator agents work to relieve bronchospasm through smooth muscle relaxation. increase in the size of the airways reduces resistance and prevents subsequent obstruction. |
Primary classifications of bronchodilators include | anticholinergic, beta-adrenergic agonists, and xanthine derivates. |
Bronchodilator Agents Indications: | Anticholinergic: asthma, arrhythmias, peptic ulcer, bladder hypermotility, Parkinsonʼs disease; beta-adrenergic: asthma, COPD, prevention of PVCs; Xanthine: asthma, bronchitis, emphysema |
Bronchodilator Agents Side effects: | (depending on class of drug) increased sensitivity to allergens/irritants, tolerance, nervousness, restlessness, toxicity, confusion, dry mouth, constipation, tremor |
Bronchodilator Agents Implications for PT: | therapists should ensure that the patient brings the bronchodilator medication to therapy and should modify exercise to avoid bronchospasm. |
Bronchodilator Agents Implications for PT | Cardiac abnormalities may indicate problems with the bronchodilator medication and side effects may indicate toxicity. Early detection of toxicity is imperative and a physician should be notified. |
