PNR 182 Jeanne Gué, MSN, RN January 25, 2010 Chapter 32: Antitussives, Mucolytics, Expecortants Pre-Administration Assessment What prescribed medications, OTC medications, or herbal products have been used now or in the past for the treatment of the same or similar respiratory problems? Do any medications such as aspirin or non-steroidal anti-inflammatory drugs (ibuprofen, Advil) precipitate asthma attacks? How effective have the medications been in the treatment of prior or current symptoms. Take baseline VS for early signs of respiratory distress: increased BP, Pulse and respiratory rate, increased temp. During the preadministration assessment the nurse documents the type of cough (productive or nonproductive) and describes the color and amount of any sputum present. Drug Class: Antitussive Agents (cough suppressants) Actions : Most -antitussives suppress the cough center in the medulla (codeine) and are called centrally acting drugs. The expected therapeutic outcome is reduced frequency of nonproductive cough to promote rest. Others are peripherally acting drugs, which act by anesthetizing stretch receptors in the respiratory passages, there by decreasing coughing. Uses: Used when pt. has dry, hacking, non-productive cough to decrease its frequency and suppress the severe spasms that prevent adequate rest at night. If the cough produces sputum, it should be treated by a primary care provider, who, based on a physical exam may or may not prescribe an antitussive. Herbal Alert p. 285 Adverse reactions : CNS:, light-headedness, dizziness, drowsiness, sedation, GI: nausea, vomiting, constipation 1

Precautions: 1. Depression of the cough reflex can cause pooling of secretions in the lungs with more serious diseases such as pneumonia and atelectasis. For this reason, using an antitussive for a productive cough is often contraindicated. 2. Antitussives are given with caution to pts with a chronic cough. 3. Indiscriminate use of antitussives by the general public may prevent early Dx and Tx of serious disorders, such as lung disease and emphysema. 4. May cause additive depressant effects when administered with antihistamines containing codeine.
