A patient is suffering from a deficiency of noradrenaline (norepinephrine). Which class of drug should be prescribed?

1. Anti-inflammatory
2. Analgesic
3. Antihistamine
4. Anti-depressant

Correct answer: Anti-depressant

Solution

Noradrenaline (norepinephrine) is a key neurotransmitter in the brain associated with alertness and mood. Its deficiency is linked to clinical depression. Anti-depressants work by increasing the concentration of monoamine neurotransmitters (including noradrenaline and serotonin) at synapses. The other options treat pain (analgesic), inflammation (anti-inflammatory), and allergic responses (antihistamine), none of which address noradrenaline deficiency.
