Which drug classification counters poisons and their effects?

• A. Analgesic
• B. Antidote
• C. Antihistamine
• D. Antibiotic

Answer: (B)

The main idea being tested is how poisons are countered. An antidote is a substance designed to counteract a toxin or its effects. It can work in different ways: neutralizing the poison chemically, blocking its action at its target (such as a receptor), or increasing its elimination from the body. This makes antidotes the specific class used to treat poisoning or toxin exposure. For example, naloxone reverses opioid toxicity by blocking opioid receptors, acetylcysteine helps with acetaminophen poisoning by supporting detoxification, and chelators like deferoxamine bind heavy metals to prevent their harmful effects. In contrast, analgesics relieve pain, antihistamines block histamine to reduce allergic symptoms, and antibiotics kill or inhibit bacteria; none are targeted antidotes for poisons.
