Clarithromycin

Clarithromycin (CAS 81103-11-9) is a semi-synthetic macrolide antibiotic derived from erythromycin, offering improved acid stability and a broader antimicrobial spectrum than its parent compound. It acts by binding the bacterial 50S ribosomal subunit to inhibit protein synthesis, and is used against respiratory tract infections, skin and soft-tissue infections, and Helicobacter pylori as part of combination regimens. Supplied — rather than directly manufactured — by Ningbo Pangs Chem Co., Ltd. to Ph. Int. standards, with free samples available, it is sold across North America, Central/South America, Western and Eastern Europe, Australasia and the Middle East.
