2.  Briefly explain the three types of drugs
discussed
◦ Antibiotics
◦ Bronchodilator
◦ Corticosteroid
 Identify the common respiratory condition(s)
the drugs are used to treat
 Knowledge of the common side effects
 Basic understanding of the drug physiology
(function)

3.  What it is…  What it treats…
◦ A chemical agent used ◦ Kills bacteria that
to disrupt the causes respiratory
metabolic process of infection
pathogenic(disease ◦ Common bacterial
causing) respiratory infections
microorganisms, antibiotics treat
namely bacteria include:
◦ Common antibiotics  Tuberculosis-bacterial
 amoxicillin, penicillin infection of the lungs
 Pneumonia-Inflammatory
condition of the lungs
that can caused by
bacteria

4.  How it works…  DISRUPTS CELL MEMBRANE
PERMEABILITY-The
◦ Antibiotics generally work antibiotic clings to the
in 4 ways bacterial cell wall causing
 INHIBITS CELL WALL the cell’s contents to leak
SYNTHESIS –Disrupts the out
creation of the bacterial cell  STOPS METABOLIC
wall, causing weakness and SYNTHESIS-Blocks bacterial
cell death. cell metabolism, so the cell
 INHIBITS PROTEIN cannot reproduce
SYNTHESIS-the antibiotic  Antibiotics are primarily
deprives protein (RNA/DNA) administered orally (by
of an essential enzyme, mouth)
causing the bacteria to stop
•Common side effects:
replicating (multiplying) or
communicating with other Nausea, diarrhea, rashes,
cells. joint pain (allergic
reactions)
Antibiotics-click to watch!
***Definitions: Synthesis- growth; Permeability-
the degree of difficulty or ease something can
be penetrated

5.  What it is…  What it treats…
◦ A chemical agent used ◦ Bronchospasm-An
to relax muscle spasm increase in tone
in the bronchial tubes (spasm) of the smooth
muscle of the bronchi
◦ Most common type of leading to the
bronchodilator is called narrowing of the airway
Sympathomimetic  Bronchospasms are
primarily caused by
allergies, infection,
◦ Common exercise or stress.
Sympathomimetic ◦ Asthma-Inflammation
drugs include; of the bronchioles
albuterol and leading to a narrowing
ephedrine of the airway

6.  How it works…
◦ Stimulates Beta-2 receptors
 Drug is taken, and it
 Stimulates Beta- 2 receptors in the lungs, which
 Activate an enzyme that increases cAMP ( a chemical in
the body)
 And finally cAMP relaxes the bronchial smooth muscle
o Bronchodilators are usually administered by oral inhalation-
inhaler
o Common side effects: nervousness, anxiety, dry mouth,
hypertension, tachycardia (increased HR)

7.  What it is…  What it treats…
◦ A chemical agent that ◦ Commonly used to
reduces inflammation treat Upper Respiratory
and swelling in the Infections (URI) such
respiratory tract as:
 Laryngitis-inflammation
◦ Cortisone is the most of the larynx
common type of  Rhinitis-inflammation of
the nasal mucosa
corticosteroid (Flonase –nasal spray)
 Asthma

8.  How it works… Common side effects: water
◦ Corticosteroids are said to: retention, delayed wound
 Reduce the inflammation of
the airway, decreasing healing, headache
sensitivity.
 Reduce the release of body
chemicals from certain
inflammatory cells, such as;
prostaglandins.
 Prostaglandins play a major
role in regulating
inflammatory states of the
body
 Increase the effect of
bronchodilators
(corticosteroids and
bronchodilators are often
coupled medications in
inhalers).
 Corticosteroids are usually
 Corticosteroid-click to
taken orally or by inhalation watch!
