Question

Which one of the following is employed as Antihistamine?

• A. Diphenyl hydramine
• B. Norothindrone
• C. Omeprazole
• D. Chloramphenicol

Answer 1

The Correct Option is A

The given question is about identifying a compound that functions as an antihistamine. Let's examine the options:

• Diphenyl hydramine: This compound is well-known for its antihistamine properties. It is commonly used to treat allergic reactions and symptoms such as itching, runny nose, and sneezing.
• Norothindrone: This is a type of progestin, a synthetic form of the hormone progesterone, used in oral contraceptives and for treating menstrual disorders. It is not an antihistamine.
• Omeprazole: This is a proton pump inhibitor used to reduce stomach acid and treat conditions like gastroesophageal reflux disease (GERD). It does not have antihistamine properties.
• Chloramphenicol: An antibiotic used to treat bacterial infections. It does not have any antihistamine properties.

Based on the examination of each option, Diphenyl hydramine is the correct answer as it is an antihistamine.

Antihistamines are substances that block the action of histamine, a chemical released by the immune system during allergic reactions. Diphenyl hydramine, often used in medications like Benadryl, is effective in alleviating allergy symptoms.

To conclude, the correct answer is:

Diphenyl hydramine

None of the other options have antihistamine properties, which confirms the choice.
