Roxithromycin

It is a macrolide antibiotic.It is similar in action to erythromycin or azithromycin.

Dirithromycin

It is a macrolide antibiotic.

Mechanism of Action:
It binds to the 50S ribosomal subunit of bacteria resulting in the inhibition of the translocation of the peptides.

Uses:
It is used to treat bacterial infections such as tonsillitis, bronchitis and pneumonia.

Erythromycin

It is a macrolide antibiotic.

Mechanism of Action:
It inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit.

Uses:
It is used for the treatment of respiratory tract infections and pertussis.

Clarithromycin

It is a Macrolide antibiotic derived from erythromycin.

Mechanism of Action:
It inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit.

Uses:It is used for the treatment of acute otitis media and infections caused by H. influenzae and S. pneumoniae.

Azithromycin

It is a macrolide antibiotic.

Action:
It binds to 50S ribosomal subunit of bacterial ribosome resulting in the inhibition of the peptidyl transferase activity.

Uses:
It is used for the infections caused by H. Influenzae, C. Pneumoniae and S. aureus.

Vertilmicin

It is an aminoglycoside antibiotic. It is structurally very similar to netilmicin.

Uses:It is a potent bactericidal agent against E. coli, S. aureus and Klebsiella pneumoniae.

Tobramycin

It is an aminoglycoside antibiotic.

Action:
It binds to 30S ribosomal subunit inhibiting bacterial protein synthesis.

Used:
It is used in the treatment of infections caused by gram negative bacteria especially pseudomonas species.
