Curator's Comment: description was created based on several sources, including www.ncbi.nlm.nih.gov/pubmed/10760175

Clarithromycin is an antibacterial drug which is used either in combination with lansoprazole and amoxicillin (Prevpac), in combination with omeprazole and amoxicillin (Omeclamox) or alone (Biaxin) for the treatment of broad range of infections. The drug exerts its action by binding to 23s rRNA (with nucleotides in domains II and V). The binding leads to the protein synthesis inhibition and the cell death.

Sample Use Guides

In Vivo Use Guide

The recommended dosages of clarithromycin tablets for the treatment of mild to moderate infections in adults are: 250 mg or 500 mg every 12 hours for 7–14 days; 500 mg every 8 or 12 hours for 10-14 days (H.pylori, in in combination with lansoprazole/amoxicillin, in combination with omeprazole/amoxicillin or omeprazole); 500 mg every 12 hours (Mycobacterial Infections).

Route of Administration: Oral

In Vitro Use Guide

The MIC values for clarithromycin were: 0.12-0.5 ug/ml (Staphylococcus aureus ATCC 29213), 0.03-0.12 ug/ml (Streptococcus pneumoniae ATCC 49619), 4-16 ug/ml (Haemophilus influenzae ATCC 49247), 0.015-0.12 ug/ml (Helicobacter pylori ATCC 43504), 1-4 ug/ml (M. avium ATCC 700898).
