Problem 11 - Arihant Objective Approach to Organic Chemistry for IIT JEE and NEET all Medical Entrances Part 4

Question

Salol is an:(a) antipyretic (b) analgesic (c) antiseptic (d) antibiotic

Step-by-Step Solution

Answer

Salol is both an antipyretic and an analgesic.

Step 1: Understanding the Terminology

To solve this question, we need to understand the definitions of each term: - An **antipyretic** is a substance that reduces fever. - An **analgesic** is a medicine that relieves pain. - An **antiseptic** is a substance that prevents the growth of disease-causing microorganisms on living tissue. - An **antibiotic** is a type of antimicrobial substance active against bacteria and is the most important type of antibacterial agent for fighting bacterial infections.

Step 2: Identifying Salol's Use

Salol, also known as phenyl salicylate, is primarily used for its ability to relieve pain and reduce fever. It is often included in medications for these purposes.

Step 3: Matching Functions with Definitions

From Step 2, we know that Salol is used to relieve pain and reduce fever. By matching these functions to the definitions provided in Step 1: - Relieving pain corresponds to an **analgesic**. - Reducing fever corresponds to an **antipyretic**.

Step 4: Answer the Question

With our findings, Salol fits the descriptions of both an **antipyretic** (reduces fever) and an **analgesic** (relieves pain). Therefore, Salol is both option (a) antipyretic and option (b) analgesic.

Key Concepts

Antipyretic

An antipyretic is a type of medicine that helps to lower body temperature and reduce fever. Fevers are a natural response of the body, typically occurring when your immune system is fighting off infections. However, when a fever becomes too high or lasts for too long, it can be uncomfortable or even dangerous. This is where antipyretics come into play.

Common examples of antipyretics are paracetamol and ibuprofen. They work by affecting the part of the brain called the hypothalamus, which is responsible for regulating body temperature. By adjusting the body's thermostat, these drugs help bring down feverish temperatures.

• Paracetamol: Often recommended for mild fevers, with few side effects.
• Ibuprofen: Also reduces fever and has additional anti-inflammatory properties.

While antipyretics are very helpful, it's important to use them as directed to avoid any potential side effects. Always follow dosage instructions and consult with a healthcare professional if you are uncertain about usage.

Antiseptic

Antiseptics are substances that reduce the possibility of infection, sepsis, or putrefaction by preventing the growth of microorganisms. They are applied to the skin or other tissues and are crucial in reducing the risk of infections, especially after injuries or surgeries.

There are several types of antiseptics, each used for various purposes. For instance:

• Alcohol: Often used in hand sanitizers and wipes due to its ability to swiftly kill bacteria and some viruses.
• Hydrogen Peroxide: Commonly used to clean wounds and prevent infection.
• Iodine: Frequently applied in medical settings before surgeries.

Antiseptics are different from antibiotics, which are taken internally or applied to tissues and target bacteria specifically. Antiseptics work on the skin to maintain cleanliness and health by killing or inhibiting the growth of microorganisms. They are a critical part of maintaining hygiene in both medical and everyday scenarios.

Antibiotic

Antibiotics are powerful medications designed to fight bacterial infections. Unlike antiseptics, which are applied externally, antibiotics are usually taken orally or injected and work within the body to combat bacterial pathogens. They target the bacteria and either kill them or stop them from multiplying.

There are various classes of antibiotics, each functioning differently. Some common classes include:

• Penicillins: Such as amoxicillin, often prescribed for ear infections and throat infections.
• Cephalosporins: Used to treat a wide range of infections from bronchitis to skin infections.
• Macrolides: Effective for people allergic to penicillin and helpful in treating respiratory infections.

It's crucial to use antibiotics correctly to prevent the development of antibiotic-resistant bacteria. This means completing the entire prescribed course, even if symptoms improve earlier, and only using antibiotics when instructed by a healthcare provider.
