What is the common cold
Upper respiratory tract disorder due to virus infection
Most common w/ the rhinovirus
What is the pathophysiology of the common cold
- rhinovirus attached to respiratory epithelia and macrophages
- virus infiltrates the host cells via endocytosis, then replicates and infection spreads to other cells
- infection stimulates host cell release of inflammatory mediators (bradykinins, prostaglandins, histamine, vasodilators), which causes hypersecretion of watery nasal fluid
- viral infection ends once enough neutralizing IgA or or IgG enters the mucosa to end viral replication
What is a protective function for human airways and lungs that can also be induced by medication
Cough
What is the pathophysiology of a cough
- cough reflex is triggered by stimulation of sensory nerve receptors, which are stimulated by both chemical (cytokines, histamine) and mechanical (dust, growth/cancer) stimuli
- action potential is then sent to the “cough center” in the medulla
What is allergic rhinitis
- hay fever
- systemic disease w/ prominent nasal symptoms and effects the upper respiratory system
- immune response to antigenic environmental allergens
- reactions typically limited to nasal cavity without systemic allergies leading to conditions such as bronchoconstriction
What is type I hypersensitivity
Immediate reactions that occur within minutes of allergen exposure
IgE mediated
What is the pathophysiology of allergic rhinitis
Allergenic particles contact nasal mucous membranes, then inducing an IgE mediated inflammatory immune response
What is the process of the immune response causing allergic rhinitis
- Airborne allergies inhaled that produce antigen specific IgE, causing sensitivity
- Second exposure, mast cells trigger release of inflammatory mediators (histamine, leukotrienes, prostaglandins, bradykinins)
- Inflammatory mediators cause vasodilation that increases vascular permeability and production of nasal secretion
- Histamine produces rhinorrhea, itching, sneezing, and nasal obstruction
- Chemokines attract allergen-destroying WBCs that increase inflammation and leads to congestion
What are some manifestations of allergies due to
- Histamine release
- Activation of H1 receptors on smooth muscles
Examples of vasoconstrictors
- NSAIDs
- Epinephrine and norepinephrine
- Antihistamines
- Decongestants
(NEAD)
What are vasoconstrictors used for
To counteract the pathophysiological effects of histamine in colds and allergies by narrowing blood vessels and increasing BP
What do decongestants do
Decrease vascular congestion in the nose
What is the pharmacology of decongestants
- alpha 1 andrenoceptor agonists
- NE released from sympathetic nerves bind to alpha-androceptors on smooth muscle, stimulating vasoconstriction
- vasoconstriction of blood vessels in nose, throat, and paranasal sinuses results in reduced inflammation and mucosal edema (rhinorrhea, congestion)
What does it mean if a product has a D after its same
It contains pseudoephedrine
Why is pseudoephedrine more effective than phenylephrine
Phenylephrine has lower bioavailability
What are the warnings w/ systemic decongestants
- uncontrolled HTN (increases BP = vasoconstriction
- glaucoma (increased intraocular pressure)
What are longer acting intranasal decongestants
Xylometazoline
Oxymetazoline
What are antitussives
Cough suppressants
What is the pharmacology of dextromethorphan (DM)
- acts on the medulla cough center to increase the cough threshold
- robitussin is an example
What happens at high doses of dextromethorphan
Converted into a psychoactive metabolite dextrorphan
Produces hallucinogenic effects similar to PCP
What is the pharmacology of codeine (methyl morphine)
- acts on medulla cough center to increase cough threshold
- usual dosages have low toxicity and little risk of addiction
Who should avoid taking codeine
Those w/ CYP2D6 polymorphism
This makes them an ultra rapid metabolizer of codeine
Can cause respiratory depression and death
What is diphenhydramine and where does it act
- nonselective (1st gen) antihistamine w/ significant sedating and anticholinergic properties
- acts on medulla to raise the cough threshold
What do expectorants (protussives) do
Decrease phlegm viscosity
What does guaifenesin (mucinex) do
Loosens and thins lower respiratory tract secretions
What effects do NSAIDs have
Analgesic
Antipyretic
Anti-inflammatory
What effects does acetaminophen NOT have
Anti-inflammatory
Anti-thrombotic
*because it is inactivated outside the CNS
What is the MOA of most NSAIDs
- COX inhibitors causing decreased prostaglandin (PGE2, PGI1) synthesis
- blocks thromboxane A2 (TXA2) synthesis, which increases bleeding (anti-thrombotic)
- block prostacyclin (PGI2) synthesis, which increases gastric acid secretion, causing gastric erosion (ulcers) and bleeding
What does pectin do and what is it in
- relieves irritation of the mucous membranes in the throat by forming a protective film (demulcent)
- component of Halls throat lozenges
What do menthol and phenol do, and what are they in

- used in: chloraseptic sore throat spray, Vicks VapoDrops
What does benzocaine do
Numbing agent
Blocks Na+ channels on neuronal cell membranes, decreasing conductance
What do antihistamines do
Compete w/ histamine for H1 receptors, blocking vasodilation
2nd gen inhibit release of mast cell mediators
What are the characteristics of 1st generation antihistamines and what are examples
Lipophilic (nonpolar)
Cross BBB
Shorter acting
Benadryl (diphenhydramine)
Unisom (doxylamine)

- somnolence (caution for excessive sedation)
- anticholinergic effects (dry mouth)
What is the pharmacology of mast cell stabilizers and what is an example
