Role of Medication (Drugs)
The administration of medication is one
of the most important responsibilities of
the healthcare professional
 We must strive to gain all possible
knowledge medicines, their use, and their
abuse
 This knowledge is of utmost importance
in giving the best possible patient care!

Role …continued
The types of things we must learn about
medications are …
 Proper use
 Abuse (improper use)
 Correct dosages
 Methods of administration (delivery)
 Symptoms of overdosage
 Abnormal reactions (allergic,idiosyncratic)

Benefits vs. Risks of drug usage
Correctly used – can be life-saving
 Unwisely used – can cause permanent
harm, may even be fatal
 “Crutches” – drugs can be thought of
this way, as aides in helping a patient heal
 Common-sense must be used when
administering drugs … and never assume!

GENERAL pharmacology terms
Pharmacology -the study of drugs and
their actions
 Pharmacy - art of preparing/dispensing
 Drug - any substance used in medicine
Chemical substance – can be synthetically
made
Plant products – crude drugs
Animal products – insulin, thyroid horm
Food substances – vitamins/minerals

SPECIFIC pharmacy terms
Additive effect – “1 + 1 = 2”
 Adverse effect – negative, unplanned
 Allergic reaction – marked reaction
 Antagonism – “1 + 1 = less than 2”
 Idiosyncratic – abnormal reaction
 Prophylactic – to prevent disease
 Side-effect – unpredictable
 Synergism – “1 + 1 = more than 2”
 Tolerance – increasing resistance

Drug Laws and Regulation
Controlled Substances Act of 1971, which
introduced the DEA (Drug Enforcement
Agency)
 Established drug ‘Schedules’, or categories,
based on the drug’s potential for abuse
 Schedules1 - 5 (often Roman
Numerals)… with (1) being highest
abuse-potential and (5) the least abuse
potential

Schedule 1 drugs (aka C-1’s)
HIGHEST potential for abuse
 NO currently accepted medical use in the
United States
 Lack of accepted safety data
 examples:
*heroin
*LSD
*marijuana

Schedule 2 drugs (aka C-11’s)
High potential for abuse
 DOES have currently accepted medical
use in the U.S. with severe restrictions
 Abuse may lead to severe psychological
or physical dependence
 examples:
*morphine *oxycodone *cocaine
*methylphenidate (Ritalin)

Schedule 3 drugs (aka C-111’s)
Abuse potential less than C-1 and C-11’s
 Currently accepted medical use in U.S.
 Abuse may result in moderate/low physical, or
high psyhological dependence
 examples:
*codeine (small amounts) *hydrocodone
*phendimetrazine (appetite suppressant)

Schedule 4 drugs (aka C-1V’s)
LOW potential for abuse
 Currently accepted medical use in U.S.
 Abuse may result in limited physical or
psychological dependence
 examples:
*diazepam *propoxyphene
*meprobamate *phenobarbital

Schedule 5 drugs (aka C-V’s)
Lowest potential for abuse
 Currently accepted medical us in U.S.
 Abuse tends to be very limited
 examples:
*compounds (mixtures) containing
limited amounts of codeine,
dihydrocodeine, hydrocodone
*Lomotil (diphenoxylate + atropine)

Drug Standards
‘Drug Standards’ list known values,
strengths, quality, and ingredients of
various drugs
 USP – American Drug Standard
 IP – International Drug Standards
 BP and The Pharmaceutical Codex –
British Drug Standards

Sources of Drug Information
These are all things you can use to
research information on drugs
 Rxlist.com – great website!
 Drugs.com – another great website!
 WebMD – disease and drug info
 Drug manufacturer’s website – useful
only if searching the Brand-name drug

Brand-name vs. generic-name
Brand-name is also referred to as the
‘Trade’ name, or ‘Proprietary’ name …
this simply means the original
manufacturer ‘owns’ the name.
 Brand-names are always CAPITALIZED
 Generic drug names are always recorded
in LOWER CASE … this is important!

Pharmaceutical Preparations
Different types of dosage forms are
needed for different applications
 These variations are necessary because of
the wide range of drug properties and
drug uses
 See pages 31 and 32 for fully detailed
information

Oral Dosage forms
Capsules - swallow
 Tablets/pills – swallow/sub-lingual
 Troches – dissolve in mouth
 Long-acting/Extended-release tabs/caps
 Elixirs – contains alcohol
 Emulsions – fat globule suspension
 Syrups – sugar, liquid
 Aerosols/inhalers - spray

Topical Dosage forms (apply)
Gels – easily spread over large areas
 Creams – absorbs quickly into skin
 Ointments – stays on surface
 Powders – wound treatment
 Lotions/Liniments
 Solutions – often used on scalp
 Tinctures/Spirits
 Suppositories – insert rectally

