Question

Low level of noradrenaline is the cause of depression. What types of drugs are needed to cure this problem? Name two drugs.

Answer 1

Hint: We should know that noradrenaline, the main neurotransmitter of the sympathetic nervous system, is responsible for tonic and reflexive changes in cardiovascular tone.

Complete step by step solution:
Noradrenaline and adrenaline are catecholamines that play major roles in the regulation of the 'inner world' of the body by the brain.
Bursts of Noradrenaline (synonymous with norepinephrine) can lead to euphoria (very happy) feelings but are also linked to panic attacks, elevated blood pressure, and hyperactivity. Low levels can cause lethargy (lack of energy), lack of concentration, attention deficit hyperactivity disorder (ADHD), and possibly depression.
So, Antidepressant drugs are used to minimize depression. Generally, these drugs inhibit enzymes catalyzing the degradation of the neurotransmitter, noradrenaline. As a result, the neurotransmitters are slowly metabolized and then it can activate its receptor for longer periods of time.

Two antidepressant drugs are:
1. Iproniazid
2. Phenelzine

Therefore, we explained the type of drugs needed to cure depression with examples.

Note: We should also know that Dopamine could also be important in major depressive disorder.
Serotonin, dopamine, oxytocin, and endorphins are famously happy hormones that promote positive feelings like pleasure, happiness, and even love.
Hormones and neurotransmitters are involved in lots of essential processes, like heart rate and digestion, but also your mood and feelings.
