Study of respiratory disease
is also known as
Pulmonology.

Spread through respiratory droplets
Highly contagious
Initially mucous membranes of nose, pharynx
swollen
Symptoms:
o Nasal congestion
o watery discharge
o Mouth breathing
o Change in tone of voice
o Sore throat, headache
o slight fever
o Cough
9. Treatment
Class Antihistamine NSAIDs Decongestants
(vasoconstrictor)
Anticholinergic
M.O.A. Preventing
histamine from
attacking to a
cellular
receptor(H₁).
Block the
production of
inflammatory
mediators called
prostaglandins(co
x2).
Acts by
stimulating the ᾳ-
adrenergic
receptor causes
vasoconstriction.
Block the action of
parasympathetic(
Ach) action on
mucus gland
secretion.
Drugs Diphenhydramine
(Benadryl),
Levocetrizine
(Xyzal),
Promethazine
(Antinaus50),
fexofenadine
(Allegra ODT)
Diclofenac(Zorvol
ex),
ibuprofen(Advil),
Ketrolac(Toradol)
Pseudoephedrine(
Nexafed),
Phenylepherine
(Contac-D)
Ipratropium
(Atrovent),
Tiotropium
(Spirivia)
Side-effects Sedative,
tranquillizers,
drowsiness
GIT irritation,
Reduce kidney
function
Hypertension,
↑ heart rate,
Glaucoma,
Urination problem
Classification of drugs :
11. Cough
Protective reflex
Caused by common cold, allergies, and infection.
Types(duration):
o Acute cough – 3 weeks
o Sub acute cough – 3 to 8 weeks
o Chronic cough - >8 weeks
Symptoms:
o Running nose
o Sneezing
o Mild fever
o Tiredness
12. Treatment
Classification of drugs:
Class Demulcents Expectorants Antitussives
M.O.A. Sooth the throat and
reduce afferent impulse
from the inflamed
mucosa.
Increase bronchial
secretion or reduce
viscosity , facilitate
removal by
coughing.
Act on CNS to
reduce tussles
impulse , suppress
coughing.
Drugs Lozenges(Vicks),
Glycerin
Liquorice(licorice)
Guaifensin
(mucinex),
Potassium iodide
(pima)

(Vicks formula44)
Carbapentane
(Solutuss)
Benzontate
(Tessalon)
Combination Drug:
Mucinex DM(dextrometorphan+guaifensin)
Tylenol+Codeine(acetaminophen+codeine)
13. Asthma
• Periodic episodes of severe but reversible bronchial
obstruction
• Frequency may lead to irreversible damage and COPD
14. Treatment
Class bronchodilator Leukotriene
Antagonists
Mast cell
stabilizer
Corticosteroid
M.O.A. A. Adrenergic
E.g.:
epinephrine(Epipen)
,
terbutaline(Bericany
l),
metaproterenol(Met
aprel)
B. Anticholinergic
E.g.:
Ipratropium(atroven
t)
C.Methyl xanthine
E.g.:theophylline(Th
eo24)
Dyphylline(Dilor)
Blocking the
enzyme 5-
lipoxygenase
Block Calcium
channel and
inhibits release
of histamine.

bronchial
hyperactivity and
suppressing
inflammatory
response.

22. Diagnostic tools:
• Nasopharyngeal swab for viral culture
• The gold standard test
• Rapid immune fluorescence test
• Viral culture
Treatment:
• Neuraminidase inhibitor antiviral medications
E.g. : Oseltamivir(Tamiflu), Zanamivir(Relenza), Peramivis(Rafivab)inj.
M.O.A. : blocking the enzyme NEURAMINIDASE, enables the virus to spread
• Immunization by vaccines
Flumist(live influenza virus)
M.O.A. : producing antibody to fight against virus.
• Possible herbal therapy
E.g. : Elderberry, Japanese wasabi leaves, Tulsi etc.
