3. CHEMICAL NAME

4. the scientific names based on the molecular structure of the drug arrangement of atom and atomic groups in the drug molecule the IUPAC name very long and too complex never used in mentioning to a drug in speech or in documents or in prescriptions or in a clinical or marketing situation Specifications of the Chemical name

5. For example- Drug Chemical name Paracetamol (antipyretic) N-(4-hydroxyphenyl) acetamide Atorvastatin (Antihyperlipidemic) (3R,5R)-7-[2-(4-fluorophenyl)-3-phenyl-4-( phenylcarbamoyl )-5-propan-2-ylpyrrol-1-yl]-3,5-dihydroxyheptanoic acid Diazepam (hypnotic) 9-chloro-2-methyl-6-phenyl-2,5-diazabicyclo[5.4.0]undeca-5,8, 10,12-tetraen-3-one or 7-chloro-1,3-dihydro-1-methyl-5-phenyl-2H-1,4-benzodiazepine-2-one.

6. GENERIC NAME

7. Specifications of Generic name the common or approved name of the drug generic name referring to any drug marketed under its chemical name without advertising. granted by the United State Adopted Names (USAN) Council commonly used to identify a drug during its useful clinical lifetime may or may not be included in the pharmacopoeia A generic medicine works in the same way and provides the same clinical benefit as its brand-name version.

8. For example- A generic medicine is the same as a brand-name medicine in dosage, safety, route of administration, effectiveness, strength, stability, and quality, performance characteristics . For example- atorvastatin , aspirin , paracetamol , captopril , metoprolol etc.

Specifications of Trade name B rand name or proprietary name given by the pharmaceutical manufacturing industries to the medicine Pharmaceutical companies probably like the use of their tradename, as this gives them some free advertising The clinicians usually prescribe drugs by their trade names.
