Drug names l.jpg
Drug Names

  • Chemical name- describes its molecular structure and distinguishes it from other drugs

Slide5 l.jpg


To indicate the disease process being treated l.jpg
To indicate the disease process being treated a manufacture for one of several reasons.

  • Azmacort- treats asthma

  • Rythmol- treats cardiac arrhythmias


To simplify the generic name l.jpg
To simplify the generic name a manufacture for one of several reasons.

  • Pseudoephedrine to Sudefed

  • Haloperidol to Haldol

  • Ciprofloxacin to Cipro


To indicate the duration l.jpg
To indicate the duration a manufacture for one of several reasons.

  • Slow-K slow release potassium supplement


Drug design l.jpg
Drug Design a manufacture for one of several reasons.

  • New drugs are discovered in one of two ways

  • Totally new chemical substance

  • Derived from molecular manipulation of a current drug


Drug design10 l.jpg
Drug Design a manufacture for one of several reasons.

  • Until recently,designing a new drug by changing the molecular structure of an existing drug was a very slow process of trial and error


Recombinant dna technology gene splicing or genetic engineering l.jpg
Recombinant DNA technology a manufacture for one of several reasons.Gene splicing or genetic engineering

  • Aided by computer design and use of enzymes, researchers are able to remove DNA chemically from one organism and transplant into other


Testing l.jpg
Testing a manufacture for one of several reasons.

  • In vitro- in glass

  • In vivo- in living

  • many guidelines set by FDA


Animal phase l.jpg
Animal Phase a manufacture for one of several reasons.

  • Precedes human testing

  • watching for toxic effects,side effects, addictions, cancerous tumors or fetal deformities


Animal phase14 l.jpg
Animal Phase a manufacture for one of several reasons.

  • Calculating the Therapeutic Index (TI)…. The difference between the dosage that produces a Therapeutic Effect and the dosage that produces a Toxic Effect


Animal phase15 l.jpg
Animal Phase a manufacture for one of several reasons.

  • NOT always a reliable indicator of how well a drug will perform in humans.


Human testing l.jpg
Human Testing a manufacture for one of several reasons.

  • 3 phases

  • 1st phase- Healthy volunteers used to study a safe dose range, evaluate side effects and establish a correct dosage.

  • Absorption


Phase ii l.jpg
Phase a manufacture for one of several reasons.II

  • Drug is given on an experimental basis to patients with the disease it will eventually be used to treat- done to determine the extent of it’s therapeutic effect


Phase iii l.jpg
Phase III a manufacture for one of several reasons.

  • Drug is administered to several hundreds of ill patients in exactly the way in which it will be used clinically (dosage & route)

  • compared to other current drugs


Phase iii human l.jpg
Phase III Human a manufacture for one of several reasons.

  • Group A

  • all patients disorder and receive new drug being studied

  • results compared to next two groups for side effects and ability to treat disorder


Phase iii human20 l.jpg
Phase III Human a manufacture for one of several reasons.

  • Group B

  • all patients have disorder meant to be treated by new drug

  • all patients receive a placebo and results are compared to other 2 groups


Phase iii human21 l.jpg
Phase III Human a manufacture for one of several reasons.

  • Group C

  • all patients have disorder meant to be treated by new drug

  • patients will be treated by another drug currently being used to treat disorder


Fda approval l.jpg
FDA Approval a manufacture for one of several reasons.

  • After reviewing all documentation on the safety and effectiveness of the new drug

  • May be protected by a patent for up to 17 years
