A

Therapeutic Duplication (leads to toxicity)

32
Q

Drug interactions involve what:

A

(1) Pharmacodynamic interactions
(2) Pharmacokinetic interactions

33
Q

This type of drug interaction occurs when one drug alters the sensitivity or responsiveness of tissues to another drug by having the same (agonistic) or a blocking (antagonistic) effect.

A

Pharmacodynamic interactions (usually occur at the receptor level but may occur intracellularly)

34
Q

This type of drug interaction occurs when a drug usually alters absorption, distribution, protein binding, metabolism or excretion of another drug.

A

Pharmacokinetic interactions (the amount and persistence of available drug at receptor site might change)

35
Q

A

Tolerance

37
Q

This is known as the development of the ability to withstand its previously destructive effect of a drug by a microorganism or tumor cells.

A

Resistance

38
Q

This type of resistance occurs when strains of microorganisms are no longer killed or inhibited by a previously effective antimicrobial drugs. A genetic change from this results from a mutation or gene acquisition.

A

Antibiotic resistance

39
Q

What happens to resistant and nonresistant organisms during antibiotic resistance?

A

The previously effective antimicrobial drug preferentially eliminates nonresistant organisms, the resistant organism become the predominant species.

40
Q

(2) Vancomycin-resistant Enterococcus (VRE)
(3) Multi-drug resistant Mycobacterium tuberculosis (MDR-TB)
(4) Carbapenem-resistant Enterobacterales (CRE)

41
Q

When can tumors become resistant?

A

If a mutation develops that confers resistant to an anticancer drug and that anticancer drug is used repeatedly, preferentially eliminating non resistant tumor cells.

(Many patients with chronic myeloid leukemia become resistant to tyrosine kinase inhibitor imantinib because of the presence of the T315l mutation)

42
Q

This type of resistance is known to affect the treatment of a number of disorders such as asthma or inflammatory bowel disease.

A

Corticosteroid Resistance

43
Q

The mechanism of Corticosteroid Resistance is not fully understood but may involve a number of different factors such as:

A

(1) Infection, oxidative stress, allergen exposure, inflammation
(2) Deficient of vitamin D3
(3) Genetic mutations or variations

44
Q

Under drug development and evaluation process, how much participants does phase 1 include?

A

It includes between 20 and 100 participants (can be healthy or have the disease or condition being studied).

45
Q

This phase of drug development and evaluation process gathers information of the drug’s adverse effects, mechanism of drug metabolism and excretion.

A

Phase 1 (The researchers observe the participants very closely and check to see how the medicine or therapy works in a human body. They may also change the dose (amount) they give of the medicine or therapy to understand what amount is best)

46
Q

How long does phase 1 last?

A

Several months

47
Q

How many participants does phase 2 include under the drug development and evaluation process.

A

Includes 300 people who have the disease or condition being studied

48
Q

Under this phase during drug development and evaluation process, the researchers obtain preliminary data on the effectivity of the drug. There is more information about how safe the medicine or therapy is; continuous evalaution on short term adverse effects.

A

Phase II

49
Q

How long does phase II last?

A

Phase 2 usually lasts from few months up to two years

50
Q

How many participants does phase III include?

A

Phase 3 includes 300 to 3,000 volunteers who have the disease or condition being studied.

51
Q

This phase under drug development and evaluation process occurs when the researchers check whether the medicine or therapy actually works to prevent, diagnose, or treat the disease or health condition it was made for.

A

Phase III (researchers learn more about the possible side effects of the medicine or therapy because more people are involved)

52
Q

If phase III trial is successful, what will happen?

A

The sponsor then applies for New Drug.

53
Q

Explain the process of the application to the FDA.

A

The process includes a review of the proposed professional labeling and inspection of the manufacturing. If the review, is favorable, the FDA may approve the drug for marketing.

54
Q

How many people does phase IV include under drug development and evaluation process?

A

Phase 4 includes thousands of people who have the disease or condition being studied.

55
Q

This phase occurs when the medicine or therapy has been approved by the food and drug administration (FDA) to be given to the public. Under this, the researchers continue to look at the new medicine or therapy’s benefits and risks (side effects) and at the way to best use it.

A

Phase IV

55
Q

What does phase IV include?

A

information on the medication’s long term safety, effectiveness, and any other benefits (identifying off label effects)

56
Q

This is categorized based on the source of the decision to recall.

A

Product Recall

57
Q

This type of product recall is done by manufacturers, traders, and distributors of health products when they decided to and or have withdrawn their product from any of the stages of the supply chain due to any safety and or quality reason.

A

Marketing Authorization Voluntary Recall (MAH) Initiated or Voluntary Recall

58
Q

This type of product recall is done when the evaluation by the PRC shows that there is reason to believe that a health product can be imminently injurious, unsafe, defective, ineffective and or grossly deceptive, and when the MAH fails to initiate a recall.

A

FDA ordered or Mandatory Recall

59
Q

This pregnancy category of drugs pertains to when adequate and well controlled studies have failed to demonstrate a risk to the fetus in the first trimester of pregnancy (and there is no evidence of risk in later trimesters).

A

Category A

60
Q

This pregnancy category of drugs pertains to when animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well controlled studies in pregnant women.

A

Category B

61
Q

This pregnancy category pertains to when animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well controlled studies in humans, but potential benefits may warrant the use of the drug in pregnant women despite potential risks.

A

Category C

62
Q

This pregnancy category of drugs pertains to when there is a positive evidence of human fetal risk based on the adverse reaction date from investigational or marketing experience or studies in humans, but potential benefits may warrant the use of the drug in pregnant women despite potential risks.

A

Category D

63
Q

This pregnancy category of drugs pertains to when studies in animals or humans have demonstrated abnormalities and or there is positive evidence of human fetal risk based on the adverse reaction from investigational or marketing experience and the risks involved in use of the drug in pregnant women clearly outweigh potential benefits.

A

28 million euros

70
Q

What happened in 2004 during the Thalidomide Tragedy: Timeline?

A

Thalidomide was made available on a named patient basis, meaning doctors can give it to patients only on a case to case basis at their own discretion, under strict controls.

71
Q

What research was published during 2007?

A

(1) A study showed that thalidomide can significantly improve the survival chances of bone-marrow cancer patients.
(2) Researchers said that adding thalidomide to standard treatment extended the livers of elderly patients with multiple myeloma by an average of 18 months.

72
Q

Q

She is an FDA inspector who prevented the drug’s approval within the United States despite pressure from the pharmaceutical company and FDA supervisors.

A

Dr. Frances Oldham Kelsey (July of 1962 her work was recognized by Pres. John F Kennedy)

79
Q

How did Kelsey reject the application for thalidomide?

A

Kelsey insisted that the application for thalidomide contained incomplete and insufficient data on its safety and effectiveness as there was a lack of data whether the drug could cross the placental barrier.

80
Q

Where was the world pharmacokinetics drawn from?

A

from the word pharmaco which means drug and kinesis which pertains to the word motion
