Question

Which of the following compounds is an example of hypnotic drug?

• A. Seldane
• B. Amytal
• C. Aspartame
• D. Prontosil

Answer 1

The Correct Option is B

To determine which of the given compounds is an example of a hypnotic drug, we need to understand what hypnotic drugs are and then evaluate each option: 

Definition of Hypnotic Drugs: Hypnotic drugs, also known as sedative-hypnotics, are a class of drugs whose primary function is to induce sleep and maintain it. They are often used in the treatment of insomnia and other sleep-related disorders.

1. Seldane: Seldane is the brand name for terfenadine, which is an antihistamine used to treat allergic conditions. It is not classified as a hypnotic drug, as its primary action is to block histamine receptors to alleviate allergy symptoms.
2. Amytal: Amytal is a trade name for amobarbital, which belongs to the barbiturate class of drugs. Barbiturates are known for their sedative and hypnotic effects and have been used historically for their ability to induce sleep. Thus, Amytal is indeed an example of a hypnotic drug.
3. Aspartame: Aspartame is an artificial sweetener used as a sugar substitute in various foods and beverages. It has no sedative or hypnotic properties, so it is not classified as a hypnotic drug.
4. Prontosil: Prontosil was one of the first synthetic antimicrobial agents, primarily used as a sulfonamide antibiotic. It does not have hypnotic properties, and its main function is fighting bacterial infections.

Based on this analysis, the correct answer is Amytal, which is a hypnotic drug.

Answer 2

Seldane→ Antihistamine
Amytal → Barbiturate (Hypnotic)
Aspartame → Artificial sweetener
Prontosil → Antibiotics
So, the correct option is (B): Amytal.
