How do tranquilisers control the feeling of depression?

Options

A. They catalyze the degradation of noradrenaline
B. they inhibit the enzyme which catalyse the degradation of noradrenaline
C. they bind with noradrenaline and form stable complex
D. all of these

Answer

To understand how tranquilizers control the feeling of depression, we can break down the explanation into several steps:

### Step 1: Understanding Depression
- Depression is often associated with low levels of certain neurotransmitters in the brain, particularly noradrenaline (also known as norepinephrine).

### Step 2: Role of Noradrenaline
- Noradrenaline is a neurotransmitter that acts as a chemical messenger in the body. It plays a crucial role in mood regulation and is involved in transmitting signals between neurons and from neurons to muscles.

### Step 3: Degradation of Noradrenaline
- In individuals suffering from depression, there is an increased degradation of noradrenaline. This degradation is facilitated by specific enzymes that break down noradrenaline, leading to lower levels of this neurotransmitter in the brain.

### Step 4: Action of Tranquilizers
- Tranquilizers, which are a type of antidepressant drug, work by inhibiting the enzymes responsible for the degradation of noradrenaline. By inhibiting these enzymes, tranquilizers help to maintain higher levels of noradrenaline in the brain.

### Step 5: Resulting Effect
- With increased levels of noradrenaline due to the action of tranquilizers, the symptoms of depression can be alleviated, leading to an improved mood and overall emotional state.

### Conclusion
- Therefore, tranquilizers control the feeling of depression primarily by inhibiting the enzymes that catalyze the degradation of noradrenaline, thus helping to restore its levels in the brain.
