What class of medication is first-line for relief of dyspnea in palliative care?

• A. Opiates
• B. Beta-blockers
• C. Antihistamines
• D. Antipsychotics

Answer: (D)

Opioids are the go-to class for relieving dyspnea in palliative care because they blunt the central perception of breathlessness and reduce the work of breathing. By diminishing the brain’s response to carbon dioxide and lowering the sensation of air hunger, they can provide rapid, meaningful relief and often lessen anxiety that worsens dyspnea. Start with a low dose of an opioid such as morphine and titrate to achieve relief with minimal sedation; options can be given orally or subcutaneously depending on the patient’s status. While oxygen, nonpharmacologic measures, and treating underlying causes are also important, opioids address the core symptom of dyspnea itself and are widely considered first-line for this purpose. The other options don’t directly target the sensation of air hunger: beta-blockers affect cardiac work and vascular parameters but aren’t a dyspnea-focused therapy; antihistamines tackle allergic symptoms rather than breathlessness; antipsychotics are used for agitation or delirium and have no primary role in relieving dyspnea.
