Pneumonia
 Infectious
/inflammatory disorders
of the lung parenchyma
 Pathology : pulmonary
alveoli and or
interstitium are filled
with WBC, RBC and
fibrin
In Indonesia based on Indonesia Health Profiles
on 2009:
• Pneumonia is one of the 10 most common
diseases in hospitals leading to highest
crude fatality rate of 7.6%, while the
respiratory tract infection rate is 0.43%.

Treat as
outpatient or inpatient
EXTREMELY IMPORTANT
DECISION
- Nature of investigational tests
- Type & route of drugs selected of treatment
- Cost of care

Azithromycin (gol azalides)
• Azithromycin inhibits bacterial protein synthesis by binding
to the 50S ribosomal subunit of susceptible bacterial
species1–3
– The ribosome is the site of protein synthesis in bacteria and other cells
– This action interferes with the translocation of the growing peptide chain from
one side of the ribosome to the other
• A key point of differentiation between azithromycin and other
macrolides is that it demonstrates a marked post-antibiotic
effect (PAE)4
– Generally, antibiotics having PAE allows for less frequent dosing than those
with minimal PAE while remaining effective
• Azithromycin is bactericidal: it prevents bacteria from growing
by interfering with their protein synthesis2,4

Azithromycin
• Azithromycin has a comprehensive spectrum of activity for its
indications in adults and children1–3
• Azithromycin shows significant activity against Gram-positive
and Gram-negative pathogens1 (Typical and Atypical)
• The antibacterial spectrum includes most of the frequent
causes of community-acquired infections, including:1
–
–
–
–
Haemophilus influenzae
Streptococcus pneumoniae
Moraxella catarrhalis
Streptococcus pyogenes
• The distinctive pharmacokinetic profile results in high and
sustained concentration in a wide range of cells and tissues2
