Which of the following drugs is an antihistamine and is commonly used to treat allergies?
Acetaminophen
Diphenhydramine
Morphine
Oxycontin
Answers (1)
Correct answer: B) Diphenhydramine
Antihistamines are drugs that are used to treat allergies by blocking the effects of histamine, which is released during an allergic reaction. Diphenhydramine is a commonly used antihistamine that works by blocking histamine receptors in the body. It is effective in treating symptoms such as itching, sneezing, runny nose, and hives. Diphenhydramine is available over the counter and by prescription in different forms, such as tablets, capsules, and liquids.
Incorrect options:
A) Acetaminophen: Acetaminophen is a pain reliever and fever reducer, but it is not an antihistamine. It works by blocking the production of certain chemicals in the body that cause pain and fever.
C) Morphine: Morphine is a powerful painkiller that is used to treat severe pain, but it is not an antihistamine. It works by binding to specific receptors in the body to block pain signals.
D) Oxycontin: Oxycontin is a type of opioid pain medication that is used to treat moderate to severe pain. Like morphine, it is not an antihistamine and works by binding to specific receptors in the body to block pain signals.
