supervision of a health practitioner as a
prescription drug and must carry the statement,
"Caution: Federal law prohibits dispensing
without prescription."

research, approval, and marketing of drugs
needed for the treatment of rare diseases?


Orphan Drug Act of 1983
Which act requires drug manufacturers to
provide proof of both safety and effectiveness
before marketing a drug?

1962 Kefauver-Harris Amendment
New Drug Approval
All new drugs, whether made domestically
or imported, require FDA approval before
they can be marketed in the United States.
 Before it will be approved, a new drug
must be shown to be both safe and
effective by the manufacturer and that its
benefits outweighs the risks.

Page 32, 33
Clinical Trials


Extensive testing begins in the laboratory doing
chemical analysis, animal testing and then
clinical trials with people. Trial participants
must give their informed consent. Children are
only part of the trial after the drug has been fully
tested on adults.
Proof that the drug is both safe and effective is
based on results of clinical trials.
Testing Phases in Humans

Phase 1
20-100 patients
Time: several months
Purpose: mainly safety
Phase 2
Up to several hundred patients
Time: several months to two years
Purpose: short-term safety but mainly
effectiveness
Phase 3
Several hundred to several thousand patients
Time: one to four years
Purpose: safety, dosage, and effectiveness
Only about 25% of drugs tested in phase 1 successfully complete phase
3 and are approved for marketing.
Clinical Trial Phase




The proposed new drug is called an
investigational new drug (IND).
Drug is only available to those in the trial, but
sometimes it will be given to groups outside the
trial who are critically ill.
Placebo drugs are often used. A placebo is an
inactive substance given in place of a
medication.
Trials are always “blind.” Patients are not told
which group they are in.
Marketed Drugs


A patent for a new drug gives its manufacturer
an exclusive right to market the drug for a
specific period of time under a brand name. A
drug patent is in effect for 17 years from the date
of the drug’s discovery.
Once a patent expires, other manufacturers may
copy the drug and release it under its
pharmaceutical or “generic” name.
Page 34 and 35
Marketed Drugs

Generic drugs must be pharmaceutically
equivalent to the patented drug – it must
have the same active ingredients, same
dosage form, same route of
administration, and same strength. And it
must be therapeutically equivalent – that
the body’s use of the drug is the same.

OTC Labels



Over-The-Counter (OTC) are drugs that do not require
a prescription.
OTC medications are not without risks. Package inserts
and labels are designed so the consumer can take them
without medical advice.
The label should include:






The product name
Name & address of the manufacturer
List of all active and other ingredients
Amount of contents
Adequate warnings
Adequate directions for use
Behind-The-Counter OTC Meds

While most OTC medications are not kept
behind the pharmacy counter, some are,
even if a prescription is not required.
 Combat
Methamphetamine Epidemic Act
(CMEA) Federal law that sets daily and monthly
limits on OTC sale of pseudoephedrine and
ephedrine.

Records of sales must be kept for 2 years
 Exempt
narcotics. (pg 37)
 Emergency contraception

Controlled Substances

Controlled Substances Act of 1970 (CSA)
established by US Congress, identifies 5
groups or schedules of drugs as controlled
substances and put strict guidelines on
their distribution.
 This
act also requires dispensers of these
substances register with the DEA.
Page 40, 41
The Five Schedules Are:

Schedule I – High potential for abuse and no accepted
medical use in the US.


Schedule II – High potential for abuse and may lead to
physical or psychological dependence, but also has a
currently accepted medical use in the US.


Heroin, some opium derivatives, and hallucinogenic substances
Amphetamines, cocaine, methadone, and various opiates
Schedule III – Potential for abuse is less than those in
Schedules I and II and there is a currently accepted
medical use in the US, but abuse may lead to moderate
or low physical dependence or high psychological
dependence.

Anabolic steroids , compounds that contain codeine
The Five Schedules con’t

Schedule IV – Low potential for abuse relative to
Schedule III and current accepted medical use in the US,
but abuse may lead to limited physical dependence or
psychological dependence.


Phenobarbital, sedative chloral hydrate, and some anesthetics
Schedule V – Low potential for abuse relative to
Schedule IV and current accepted medical use in the
US, but abuse may lead to limited physical dependence
or psychological dependence.


Limited amounts of codeine included in this group
Exempt narcotics are in this group
In case you were wondering?



Opiates and Opioids are drugs that are most
commonly used for their euphoric and/or
analgesic effects.
Opiates are drugs that are derived from the
Opium poppy plant.
The term 'Opioid' is used to describe a
compound that binds opioid receptors in the
brain, and produces effects characteristic of
naturally occurring opiates.
Opiate drug names.

Some of the more well known semisynthetics opiates, that is to say narcotic
drugs, created from morphine, codeine
and thebaine are heroin, hydrocodone,
hydromorphone, oxycodone,
oxymorphone, and there are many others.
Medical Marijuana Debate
Medical marijuana is not approved by the
FDA
 Federal law does not recognize the
difference between medical and
recreational use of the drug
 MM is treated like cocaine or heroin by the
federal government and users can be
imprisoned by federal drug enforcement
agents

Public Safety
The FDA process is thorough but it is
impossible to fully prove that a drug is safe
for use.
 To monitor this the FDA has a monitoring
system called MedWatch.
 Prescribers are encouraged to voluntarily
report any adverse effects by approved
drugs.

Page 44, 45
Recalls

Action to remove a drug from the market
and are voluntary on the part of
manufacturer
I – strong likelihood that the product will
cause serious adverse effects or death
 Class II – product may cause temporary but
reversible adverse effects, little likelihood of
serious adverse effect
 Class III– the product is not likely to cause
adverse effects

Law and the Technician

Federal law provides a foundation for state
laws that govern pharmacy practice.
 These
laws guarantee patient rights including
rights to privacy, confidentiality, right to file
complaints, right for informed consent and the
right to refuse treatment.
Page 46, 47
Law and the Technician
State Law is responsible for licensing all
prescribers and dispensers.
 Many states have stricter regulations than
federal law.

A
few states allow pharmacists to prescribe
under limited conditions.
 States regulate pharmacy technician by
holding the pharmacist responsible for the
technicians performance.
Liability
Legal liability means you can be
prosecuted for misconduct.
 You can be guilty of misconduct by simply
failing to do something you should have
done.
 You are liable even if you are directed to
do something by your supervisor.

 Misconduct
is called negligence
Liability

Ways the pharmacy tech can be negligent:
 Incorrectly
labeling the prescription
 Breaking confidentiality
 Failing to recognize expired drugs
 Calculation errors
 Dispensing the wrong medication
 Incorrect handling of a controlled substance
 Inaccurate record keeping
