Get Creative!


We discussed how the drug and body cell are
like a lock and key. The drug can only fit in
one receptor cell on the cell.
Your task:

Draw a representation of the “lock and key” or the
drug and its receptor. Be creative. Do not draw a
lock and key. Find another way to represent the
drug locking on to the body cell.


Use color.
Label the drug and the receptor.

Factors that Determine a
Drug’s Effects

Drugs can cause unwanted effects, the most serious
being dependence.

Drug dependence is the continued need for the effects of a
drug even when those effects harm the body, mind and
relationships.

Psychological Dependence- strong emotional desire to
continue to use a drug

Physical Dependence- a condition in which someone
develops a tolerance for a drug or shows withdraw
symptoms without it.
How Drugs Affect the Body

Tolerance is what happens when the body
becomes used to a drug and needs a larger
amount to produce the same effects.

Withdrawal symptoms are unpleasant
reactions that occur when a drug is no longer
present in the body.
Prescription and Over-theCounter Drugs

Prescription Drugs- a medication that can
only be obtained with a written order from a
physician.

Brand name drug has a registered name or
trademark assigned to it by the company that
makes it. (Lipitor)
Prescription and Over-theCounter Drugs

A Generic Drug is a drug that contains the
same active ingredients as a brand-name
drug, but has no registered trademark.

Generic Drugs are usually less expensive.
Prescription and Over-theCounter Drugs

An over the counter (OTC) drug is a drug that
people can buy without a physician’s
prescription.

OTC drugs include:

Cough syrups
Prescription and Over-theCounter Drugs

Regardless of whether the medicine you are taking
is a prescription or an over the counter drug, you
should read all of the warnings and dosage
information to ensure that you do not have any
unwanted side effects.



Do not use the medication it is past its expiration date.
If the tamper resistant seal is broken, take the medication
back.
If the label says the medication may cause drowsiness, do
not engage in an activity such as riding a bike.
Use and Misuse

In your groups, you will be examining an OTC label.
Each group will have one container. You will need
to find all or most of the information asked for in the
“OTC Seek and Find” worksheet.

Following this, each student will need to explain one
way the drug could be misused and the possible
effects of misuse.

You will have 3-4 minutes with each container.
