What are antagonistic drugs ?

Explanation

**Step-by-Step Solution:**

1. **Definition of Antagonistic Drugs**: Antagonistic drugs are substances that bind to specific receptors in the body but do not activate them, leading to no biological response. They essentially block the action of agonist drugs.

2. **Comparison with Agonist Drugs**: To understand antagonistic drugs better, it's important to compare them with agonist drugs. Agonist drugs activate receptors and produce a biological response, while antagonists prevent activation.

3. **Mechanism of Action**: When an antagonistic drug binds to a receptor, it occupies the receptor site but does not trigger any response. This blocking action can inhibit the effects of agonist drugs that would normally activate those receptors.
