Problem 40 - A Complete Resource Book in Chemistry for JEE Main

Question

Which of the following is used for inducing sleep? (a) bithional (b) barbituric acid derivatives (c) paracetamol (d) chloroquine

Step-by-Step Solution

Answer

Barbituric acid derivatives are used for inducing sleep.

Step 1: Understanding Sleep Induction

The question is asking about a substance that induces sleep. This means we are looking for something that acts as a sedative or hypnotic, which are types of drugs used to facilitate the onset and maintenance of sleep.

Step 2: Analyzing Options

Let's examine each choice given: - **Bithional**: This is commonly used as an antiseptic agent and antimicrobial, not for sleep induction. - **Barbituric acid derivatives**: These are a class of drugs known to act as central nervous system depressants, which can induce sleep. Examples include phenobarbital and pentobarbital. - **Paracetamol**: Commonly used as a pain reliever or fever reducer, it is not used for sleep induction. - **Chloroquine**: An antiparasitic drug used primarily for malaria, it does not induce sleep.

Step 3: Final Decision

Based on the analysis, barbituric acid derivatives stand out as the group known for their ability to induce sleep. They are used as sedatives and hypnotics in medical settings.

Key Concepts

Sleep-Inducing Drugs

Sleep-inducing drugs are medications that help people fall asleep and stay asleep. They work by altering the chemical balance in the brain to induce drowsiness. Sleep is essential for various bodily functions and overall well-being, making these drugs important for individuals struggling with sleep disorders. While there are many types of sleep-inducing drugs, they all aim to facilitate a good night's sleep.

Some common applications of sleep-inducing drugs include:

• Managing insomnia
• Assisting with sedation before medical procedures
• Helping with anxiety that may interfere with sleep

It's crucial to use these drugs under medical supervision to avoid dependency or side effects.

Sedatives

Sedatives are a broad class of drugs used to promote calmness and relaxation. They function by depressing the body's central nervous system, which reduces excitement and anxiety levels. Sedatives are often used in both medical and recreational contexts. In medicine, they are typically prescribed for anxiety disorders, tension, and insomnia.

Here are some key features of sedatives:

• They can have calming effects, making them useful in stressful situations.
• They are often combined with other medications to enhance their effects.
• They are available in different forms, like pills, liquid, or injectables.

It's essential to utilize sedatives carefully, as overuse can lead to serious health risks, including addiction.

Barbituric Acid Derivatives

Barbituric acid derivatives are a group of drugs derived from barbituric acid and have historically been pivotal in treating sleep-related issues. These compounds act as central nervous system depressants, leading to sedation, hypnotic effects, and anesthesia in higher doses. They were among the first sleep-inducing drugs developed, though their use has decreased due to the risk of dependence and the availability of safer alternatives.

Some important points about barbituric acid derivatives include:

• Commonly known examples are phenobarbital and pentobarbital.
• They work by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA).
• They are classified based on their onset and duration of action, such as short-acting or long-acting.

Despite their risky profile, they are still used in specific medical scenarios, such as epilepsy management, but under strict medical guidance.
