Which medication is the drug of choice for symptomatic hypotension?

• A. Dopamine
• B. Epinephrine
• C. Norepinephrine
• D. Phenylephrine

Answer: (A)

Symptomatic hypotension needs a medication that can both raise pressure and support heart performance. Dopamine fits because its effects change with the dose: at moderate doses it stimulates beta-1 receptors, increasing heart rate and contractility to boost cardiac output; at higher doses it activates alpha-1 receptors, increasing vascular resistance to raise blood pressure; and at low doses it can help renal perfusion. This combination helps restore mean arterial pressure and improve tissue perfusion in a hypotensive patient. While other vasopressors like norepinephrine or phenylephrine are essential in certain shock states, dopamine’s dose-dependent inotropic and vasopressor effects make it a common choice when symptomatic hypotension with low cardiac output is a concern. Monitor for tachycardia, arrhythmias, and extravasation, and adjust dosing carefully to balance perfusion with risks.
