Mucolytics A mucolytic is a drug that loosens respiratory secreations. Use: Bronchitis. Cystic Fibrosis. COPD. Atelectasis. Acetaminophen toxicity.
Mucolytics:Actions: Decreases viscosity of secretions by breaking disulfide links of mucoproteins. Serves as a substrate in place of glutathione, which is necessary to inactivate toxic metabolites in acetaminophen overdose. Example: acetylcysteine (Acetadote, Mucomyst).
Mucolytics Contraindications: Hypersensitivity. Increased intracranial pressure. Status asthmaticus.
Mucolytics Precautions: Pregnancy. Hypothyroidism. Addison’s Disease.
Mucolytics Precautions Con’t CNS depression. Brain tumor. Asthma. Renal / heptic disease. COPD. Psychosis. Alcoholism. Convulsive disorders. Breastfeeding.
Mucolytics Side Effects CNS: dizziness, drowsiness. CV: hypotension. EENT: rhinorrhea. GI: nausea, stomatitis, constipation, vomiting, anorexia, hepatotoxicity. Integ: urticaria, rash, fever, clamminess, pruritus. Resp: bronchospasm, hemoptysis, chest tightness.
Mucolytics:Interactions Do not use with iron, copper, rubber. Do not mix with antibiotics. Increases the effects of nitrates
Mucolytics Nursing Implications Assessment: Cough: type, frequency, character, including sputum. VS: resp rate, rhythm, increased dyspnea. CV: dysrthythmias. Lab Tests: ABGs (increased CO2: asthma).
Mucolytics Nursing Implementation Administration (PO): Mix with soft drinks to disguise taste. (Give within one hour). Give ½ - 1 hour before meals for better absorption and to decrease nausea. Assistance with inhaled dose: bronchodilator if bronchospasm occurs.
Mucolytics Nursing Implementation Antidotal: within 24 hours. Store in refrigerator (up to 96 hours after opening). Gum, hard candy, frequent rinsing of mouth for dryness of oral cavity
Mucolytics Patient Teaching About mucolytic use. Unpleasant odor will decrease after repeated use. Discoloration of solution after opening, does not affect effectiveness of medication. Report vomiting, since dose may need to be repeated.
Mucolytics Evaluation Absence of purulent secretions. Absence of hepatic damage in acetaminophen toxicity.
What is the action of Mucolytics? Loosens respiratory secretions. Reduces the viscosity of respiratory secretions by direct action on the mucus.
