4. CLASSIFICATION
OF
ANTIBIOTICS?

5. 1. On the basis of spectrum of antibiotic:
Broad spectrum antibiotics:
The Broad spectrum antibiotics affect several
types of bacteria and fungi.
Narrow spectrum antibiotics:
These are used only when we know the specific
type of the microorganism.

6. 2. One the basis of mode of action of antibiotic:
Bactericidal antibodies:
They kill bacteria by inhibiting cell wall synthesis.
Example include:
Beta-lactam antibiotics----
o Penicillin(amoxicillin) [ commonly used for infection
o Cephalosporin(Keflex) [commonly used for surgical prophylaxis.]
o Metronidazole [commonly used as bacterial infections like
skin and GI Tract infection]
Bacteriostatic antibiotics:
They limit the growth of bacteria by interfering with bacterial protein production, DNA
replication.
Example:
o Tetracycline [used as respiratory tract, urinary tract, etc.]
o Sulfonamide [used as diabetes and pain relief ]

(erythromycin)
