Drugs used to bind to receptors, inhibiting its natural function and blocking a message are called:
- (A)Agonists
- (B)Antagonists✓ Correct
- (C)Allosterists
- (D)Anti histaminists
Answer: (B)
Solution
Antagonists are drugs that bind to receptors and block or inhibit their natural function, preventing the receptor from being activated by its natural ligand (agonist). They do not activate the receptor themselves but prevent activation by blocking the binding site. In contrast, agonists are drugs that bind to receptors and activate them, mimicking the natural ligand. Antihistamines are a specific type of antagonist that blocks histamine receptors. The general term for drugs that block receptor function is antagonists.
