2. Drug Nomenclature the systematic naming of drugs, especially pharmaceutical drugs. The term drug nomenclature implies that there are several names that can be used to identify a drug.

3. Chemical Name Generic Name Trade name (Brand name)

4. C H E M I C A L NA M E

5. 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

6. For example- Drug Chemical name P a r ace t a m ol (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 ( h yp n otic) 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.

8. 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.

9. 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.

10. Specifications of Trade name Brand 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. The use of many trade names for the same drug can be a cause for confusion.

11. For example The tradename for diazepam Valium (from the Roche pharmaceutical company), Valpam (Arrow pharma), Antenex (Alpha pharm), Ducene (Sauter pharma).

13. Questions

14. What are generic drugs? Generic drugs tend to cost less than their brand-name counterparts because generic drug applicants do not have to repeat animal and clinical (human) studies that were required of the brand-name medicines to demonstrate safety and effectiveness.

15. Why do generic medicines often cost less than the brand-name medicines? Generic drugs tend to cost less than their brand-name counterparts because generic drug applicants do not have to repeat animal and clinical (human) studies that were required of the brand-name medicines to demonstrate safety and effectiveness. The reduction in upfront research costs means that, although generic medicines have the same therapeutic effect as their branded counterparts, they are typically sold at substantial discounts, an estimated 80 to 85% less, compared with the price of the brand-name medicine. According to the IMS Health Institute, generic drugs saved the U.S. healthcare system

16. How Does FDA monitor side effects or safety issues with generic medicines? FDA takes several actions to ensure safety and quality before and after a new or generic medicine is approved. FDA monitors all approved drug products, including generics, to make certain the medicines at all levels of the supply chain, from active pharmaceutical ingredients (APIs) to products being sold to consumers, are safe, effective, and high quality. FDA also monitors and investigates reports of negative patient side effects or other reactions. The investigations may lead to changes in how a product (brand-name and generic) is used or manufactured, and FDA will make recommendations to health care professionals .
