Key Terms:
Define the following Terms:
• Allergy: An excessive reaction that leads to an inflammatory response when a person
comesinto contact with a substance (allergen) to which he or she is sensitive. It is common
immuneresponse to substances such as pollen, animal dander, food, or dust. Also known
as hypersensitivity.
• Antihistamine: Drugs that stop histamines from attaching to histamine receptors in the
tissuesand producing inflammatory and allergic symptoms. This action counteracts the
response of histamine in causing smooth muscle contraction and dilation and leakage of
capillaries.
• Antitussive: Drugs that work to prevent and or relieve coughing.
• Asthma controller drug: Drugs that have the main purpose of preventing an asthma
attack.Also known as asthma prevention drugs. These drugs must be taken daily even
when no asthma symptoms are present. Also known as prevention drugs.
• Asthma reliever drug: Drugs that have the main purpose of stopping an asthma attack once
ithas started. Also known as asthma rescue drugs.
• Bronchodilator: Drugs that relax the airway smooth muscles allowing the lumen of the
airwaysto widen.
• Cholinergic Antagonist: Drugs that block the action of acetylcholine thereby inhibiting
theparasympathetic nervous system response. Also known as cholinergic blockers,
parasympatholytics, or anticholinergic drugs.
• Corticosteroid: Drugs built on the structure of cholesterol that are able to prevent or
limit inflammation and allergy by slowing or stopping production of the mediators
histamine andleukotriene.
• Decongestant: Drugs that reduce the swelling of nasal passages by shrinking the small
bloodvessels in the nose, throat, and sinuses so breathing is easier.
, • Leukotriene inhibitor: drugs that block leukotriene response and lessen or prevent
thesymptoms of allergy and asthma.
• Long-acting beta-adrenergic agonist (LABA): Orally inhaled drugs that bind over time to
betaadrenergic receptors and are used as asthma controller drugs that must be taken on
a daily schedule to prevent bronchospasms and asthma attacks even when symptoms
are not present.
• Mast cell stabilizer (cromone): Drugs that work on the surface of mast cells and prevent
themfrom opening to release the inflammatory mediators.
• Mucolytics: Drugs that decrease the thickness of respiratory secretions and aid in
theirremoval. Also called expectorants.
• Short-acting beta-adrenergic agonist (SABA): Orally inhaled drugs that bind rapidly to beta
adrenergic receptors and can start smooth muscle relaxation within seconds to minutes.
Alsoknown as asthma reliever or rescue drugs.
• Sympathomimetics: Drugs that mimic the sympathetic nervous system and have the
sameactions as the bodys own adrenalin. Also called beta and or alpha adrenergic
agonists.
Allergy
• Describe what an allergy is: An excessive reation that leads to an inflammatory response
whena person comes into contact with a substance or allergen to which he or she is
sensitive.

from the body.
• The lymphocytes make five different antibodies or immunoglobulins (Igs) for protection,
listthem:
IgA, IgD, IgE, IgM, IgG
• With immunoglobulin is the antibody defense against allergens?
It is against allergens
• What important mediators are released by WBCs when antibodies react with allergens?
Histamines and leukotriene.
• What does histamine start?
The inflammation
• What does leukotriene do? Works with histamine to keep the inflammatory response
goingonce it has started.
• These mediators, especially histamine cause what to happen in the body?
, Contraction of smooth muscle an dilation and leakage of capillaries .
Drug Therapy for Allergy
• Drugs used to treat allergies are those that interfere with what?
Inflammation
• What drugs interfere with inflammation?
Antihistamines, leukotrienes blockers, and corticosteroids.
• Decongestants are other drugs that can help lessen the symptoms of allergy but they do
notinterfere with what?
Inflammation
Antihistamines
• What do antihistamines do?
Stop histamines from attaching to histamine receptors in the tissues and producing
inflammatory and allergic symptoms.
• What are mast cells?
The chief controllers of the immune system
• What happens when mast cells are activated?
They release histamine
• What are the two types of histamine?
H1 and H2
• Blocking the H1 receptors what does this do?
