Dextroamphetamine is used to treat which condition among those listed?

• A. Narcolepsy
• B. Obesity
• C. Hypertension
• D. Diabetes

Answer: (A)

Dextroamphetamine is a central nervous system stimulant that increases dopamine and norepinephrine in brain circuits that regulate arousal. In narcolepsy, the main issue is excessive daytime sleepiness from impaired wakefulness control, so a stimulant that promotes alertness directly helps patients stay awake during the day and improves functioning.

While stimulants can have appetite-suppressing effects, they’re not the standard or preferred treatment for obesity today due to safety concerns and the availability of other strategies. Hypertension and diabetes are not treated with dextroamphetamine; stimulants can raise blood pressure and affect heart rate, and they don’t address the metabolic needs of diabetes.
