Generic Name

Definition

The generic name of a drug is its official, non-proprietary name assigned by the United States Adopted Names Council. It is usually the pharmacologic or chemical name and is used universally across manufacturers. Trade (brand) names vary by manufacturer.

Examples

• Acetaminophen (generic) → Tylenol (brand)
• Ibuprofen → Advil, Motrin
• Lisinopril → Zestril, Prinivil
• Furosemide → Lasix
• Metoprolol → Lopressor, Toprol XL

Clinical Significance

Generic medications contain the same active ingredient, strength, and bioavailability as brand-name equivalents but are typically less expensive. Prescribers, pharmacists, and nurses commonly use generic names to avoid confusion and ensure consistent communication across settings.
