In pharmacology, approximately 7% of approved drugs did not have a known target at the time of approval, highlighting the complexity of how drugs work. Understanding **what does mechanism of action mean** (MOA) involves exploring the specific biochemical interactions a drug has with the body, which is crucial for modern drug development and therapeutic applications.

Approximately 95% of all known receptors are proteins, and the precise way drugs bind to them determines their therapeutic effect. This is governed by the chemical forces involved, defining what are the three major types of drug receptor bonds.

According to a 2021 review in *Anesthesiology and Pain Medicine*, most drugs work as either agonists or antagonists. This fundamental principle of pharmacology is key to answering the question, **what does it mean when a drug is an agonist or antagonist?**. It explains how medicines interact with the body's cellular machinery to trigger or prevent a biological response.
