Klamer® 250 mg/5 mL Oral Suspension Granules for Oral Suspension contains clarithromycin, a macrolide antibiotic used to treat a variety of bacterial infections. Doctors commonly prescribe this medicine to treat infections affecting the respiratory tract, skin, and soft tissues.
Clarithromycin works by stopping the growth of bacteria. It interferes with bacterial protein production, which bacteria need to survive and multiply. As a result, the medicine helps the body eliminate infection-causing bacteria.

Doctors may also prescribe Klamer oral suspension for infections such as bronchitis, pneumonia, sinusitis, and throat infections. In addition, it may be used as part of combination therapy for Helicobacter pylori infections associated with stomach ulcers.
The medicine comes as granules for oral suspension, which must be mixed with water before use. This formulation helps patients, especially children, take the medicine more easily.
After preparation, each 5 mL of oral suspension contains:
Clarithromycin – 250 mg
The granules may also contain inactive ingredients (excipients) that help stabilize the suspension and improve taste.
Clarithromycin belongs to the macrolide antibiotic class.
The medicine works by inhibiting bacterial protein synthesis. It binds to bacterial ribosomes and blocks the production of essential proteins. Consequently, bacteria cannot grow or multiply.
This action helps:
Stop bacterial growth
Control the spread of infection
Support the body’s immune system in eliminating bacteria
Therefore, clarithromycin helps treat bacterial infections effectively.
