Ex. Need to know pts BP before giving BP meds or can you give 2 particular drugs together?

19
Q

How are new drugs approved?

A

FDA- Food and drug administration
-Chemical identified, undergoes strict scientific tests (only 5 in 100,000 will eventually be marketed drugs)

20
Q

What are the stages of a clinical trail?

A
  1. Preclinical trial
  2. Phase I studies
  3. Phase II studies
  4. Phase III studies
  5. Phase IV studies
21
Q

Preclinical trials

A

Tested on lab animals for therapeutic and adverse effects

22
Q

Phase I studies

A

Healthy human volunteers are used to test the drug

23
Q

Phase II studies

A

Drug is tried on patients who have the disease that the drug is designed to treat
(After strong evidence of success in this phase can move to Phase III)

24
Q

Phase III studies

A

-The drug is used in a vast clinical market.
-Prescribers informed of adverse effects and monitor their patients closely.
-Unexpected responses may occur and the drug may be withdrawn from the market

25
Q

Phase IV studies

A

-Continued evaluation by the FDA
-Postmarket of the drug
-Available to everybody
-Not in signed clinical trial
-If severe adverse reactions emerge manufacturer request black box warning or adding serious effects

26
Q

Schedule 1 controlled substances

A

-Not approved for medical use, no reason to prescribe
-Heroin, LSD
-No therapeutic effect

27
Q

Schedule 2 controlled substances

A

-Used medically, but HIGH potential for abuse
-No refills, need new prescriptions every time
-Narcotics (opioids), amphetamines (Hydromorphine (Dilaudid), oxymoron, oxy cotton)

28
Q

Schedule 3 controlled substances

A

-Less potential for abuse
-Non barbiturate sedatives, non-amphetamines, stimulants (lortab, vicodin)

29
Q

Schedule 4 controlled substances

A

-Some potential for abuse
-Primary sedatives, anti anxiety meds (Xanax, valium, ambien)

30
Q

Schedule 5 controlled substances

A

-Low potential for abuse
-Medications containing small amounts of certain narcotics or stimulants, usually antitussives (cough suppressants with some codeine, ephedrine containing medications)

31
Q

Over the counter meds

A

-What he take for regular aches, pains, tummy aches, etc.
-Over 80 classes of OTC meds
-Antihistamines, sleep aids, analgesics, antacids, laxatives
-Consumers able to diagnose own condition and monitor effectiveness easily
-Low risk of side effects and low abuse potential
-Some OTC medications are available only behind pharmacy counter due to abuse possibility (Sudafed, narcan)

32
Q

Dietary and Herbal Supplements

A

-Can only claim affect on body structure or function (not medical condition)
-Dietary supplement health education act- can’t claim medical treatment and purity standards
Ex. St Johns Wort- affects emotional balance (not treats depression)
-Label restrictions on dietary and herbals

33
Q

Adverse interactions between drugs and herbals

A
