DRUG NOMENCLATURE
<p>One drug, three names?.... Why does Paracetamol suddenly become Acetaminophen in another country, and why do brands like Panadol or Tylenol all contain the same thing? </p><p>Today, you’ll learn exactly why drugs have multiple names and how to identify what really matters as a pharmacology student.
</p><p><strong>Drug nomenclature</strong> simply means the systematic naming of pharmaceutical drugs. </p><p>Every drug has several names, but they all refer to the same substance.
</p><p>In pharmacology, understanding drug names prevents confusion and helps you recognize the same drug even when it appears under multiple labels.
</p><h1><strong>MAJOR NAMES OF A DRUG
</strong></h1><p>Drug nomenclature is built around three essential names which are:
</p><p>1. <strong>Chemical name or Molecular name or Scientific name.</strong></p><p>2. <strong>Generic name or Non-proprietary name or Approved name.
</strong></p><p>3. <strong>Brand name or Proprietary name or Trade name.</strong></p><p><br/></p><p>The <strong>chemical</strong> name describes the molecular structure of the drug. Example is N-(4-hydroxyphenyl)acetamide, which is the chemical name of Paracetamol. The name is mostly used by chemists and researchers.
</p><p>The <strong>generic</strong> name is the official, universally accepted name assigned by an international body. Examples are Paracetamol, amoxicillin, ibuprofen, and many more. The name can be used by anyone.
</p><p>The <strong>brand</strong> name is the copyrighted name given by pharmaceutical companies for marketing. Example are Tylenol, Panadol, and Calpol, which are the brand name of Paracetamol.
</p><h1>WHY DRUG NOMENCLATURE MATTERS
</h1><p>• To avoid medication errors
</p><p>• To recognize the same drug across different countries.
</p><p>• To understand drug classes by name patterns.
</p><p><br/></p><p>To avoid confusion, always remember that the chemical name is the long <strong>scientific</strong> name, the generic name is the drug <strong>real</strong> name, and the brand name is the <strong>marketing</strong> name.
