Study Notes
Common Symptoms and Visiting Patterns
- Cough is the most common symptom prompting patients to seek outpatient medical care.
- Cough frequently leads patients to medical settings, especially during acute respiratory events.
Cough Reflex and Classification
- The cough reflex is initiated by irritants in the respiratory tract.
- Subacute cough is classified with a duration range of 3 to 8 weeks.
- Certain conditions, such as non-respiratory illnesses, are not considered etiologic contributors to acute cough.
Functions and Mechanisms of Cough
- The primary function of the cough reflex is to clear the airways of irritants and secretions.
- The glottis plays a vital role during cough initiation by temporarily closing to build up pressure before expulsion.
Medications for Cough
- Dextromethorphan is indicated for suppressing non-productive cough caused by airway irritation.
- Guaifenesin, an expectorant, aids in treating cough by thinning mucus, facilitating easier expulsion.
- Benzonatate is a nonopioid cough suppressant with no analgesic, sedative, respiratory depressant, or addictive properties at usual doses.
- Codeine and hydrocodone act centrally in the medulla to raise the cough threshold and suppress coughing.
Toxic and Risky Medications
- Camphor can be toxic if ingested, leading to severe reactions such as burning sensations, nausea, vomiting, seizures, and potentially fatal outcomes.
- The use of codeine should be avoided in chronic cough associated with conditions like asthma, COPD, or emphysema, as well as in smoker’s cough.
- Dextromethorphan is commonly abused for its euphoric effect, resembling phencyclidine (PCP).
Summary of Indications
- Medications indicated for the suppression of non-productive cough include dextramethorphan and benzonatate, while guaifenesin is used to facilitate productive cough through mucus clearance.
