In the following which can be used as an antidepressant drug ?
Salvarsan
Ofloxacin
Erythromycin
Serotonin
Chloroxylenol
The Correct Option is D
Approach Solution - 1
Analysis of drug options:
- Salvarsan: Arsenic-containing antibacterial (not antidepressant)
- Ofloxacin: Fluoroquinolone antibiotic
- Erythromycin: Macrolide antibiotic
- Serotonin: Neurotransmitter (5-HT), target of SSRIs - selective serotonin reuptake inhibitors (antidepressant mechanism)
- Chloroxylenol: Antiseptic/disinfectant
Key point: While serotonin itself isn't administered as a drug, it's the biochemical target of most antidepressant medications.
Thus, the correct option is (D): Serotonin.
Approach Solution -2
1. Understanding antidepressant drugs:
Antidepressant drugs are medications used to treat depression and other mental health conditions by balancing neurotransmitters in the brain, such as serotonin, dopamine, and norepinephrine.
2. Analyze the given options:
- (A) Salvarsan: Salvarsan is an arsenic-based drug historically used to treat syphilis. It is not an antidepressant.
- (B) Ofloxacin: Ofloxacin is an antibiotic used to treat bacterial infections. It is not related to antidepressant activity.
- (C) Erythromycin: Erythromycin is another antibiotic used to treat bacterial infections. It is not an antidepressant.
- (D) Serotonin: Serotonin is a neurotransmitter that plays a key role in regulating mood, emotions, and sleep. While serotonin itself is not administered as a drug, many antidepressants work by increasing serotonin levels in the brain (e.g., SSRIs like fluoxetine). Thus, serotonin is closely associated with antidepressant mechanisms.
- (E) Chloroxenol: Chloroxenol is an antiseptic and disinfectant. It is not used as an antidepressant.
3. Identify the correct answer:
Among the given options, serotonin (D) is directly associated with antidepressant action due to its role in mood regulation.
4. Final answer:
The correct option is (D) Serotonin.

Chemistry in Everyday Life
The scientific study of matter’s properties and behaviour is known as chemistry. It is a natural science that studies the elements that makeup matter, as well as the compounds, made up of atoms, molecules, and ions: their composition, structure, qualities, and behaviour, as well as the changes that occur when they mix with other things.
- Importance of Chemistry in Food - Chemicals are the fundamental components of everything. Chemical molecules make up all food, including carbs, vitamins, lipids, proteins, and fibre, which are all safe and often desirable.
- Importance of Chemistry in Medicines - Medicines or pharmaceuticals are chemical substances that are used to treat diseases and relieve pain. Chemistry has made significant contributions to health care. Chemistry, for example, aids in the manufacture and application of surgical materials.
- Importance of Chemistry in Cosmetics - In our daily lives, we use lotions, fragrances, talcum powder, and a variety of other cosmetic goods. All of these items are developed in laboratories using chemicals for our health and skin.
- Importance of Chemistry in Soaps and Detergents - Soaps are sodium and potassium salts of fatty acids with greater molecular weights, such as stearic acid, palmitic acid, and oleic acid. Sodium salts of long-chain alkyl hydrogen sulphates or sodium salts of long-chain alkyl benzene sulphonic acids are commonly used as detergents.
