クラリトロマイシン

Clarithromycin belongs to the group of macrolide erythromycin antibiotics. Owing to its broad-spectrum antibacterial activity, several dosage forms of clarithromycin have been formulated. It is widely utilized to treat the infections caused by Chlamydia, Mycoplasma, Legionella, Helicobacter pylori, and Mycobacterium avium complex. It is also known to be active against HIV-related opportunistic infections.

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Clarithromycin may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by ultra-performance liquid chromatography (UPLC), high performance liquid chromatography (HPLC) and time-of-flight-secondary ion mass spectrometry (ToF-SIMS) techniques. It can be used as a reference standard in validating the concentration of clarithromycin in human plasma samples using liquid chromatography coupled with tandem mass spectrometry (LC-MS-MS). Clarithromycin may also be used as a test reference standard to validate and compare its purity using two different types of methods, quantitative nuclear magnetic resonance (qNMR) and high performance liquid chromatography (HPLC).
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

クラリスロマイシンは、細菌のタンパク質合成を妨げるマクロライド系抗生物質です。クラリスロマイシンはエリスロマイシンの酸安定バージョンであり、グラム陰性菌に対して特に効果的です。この半減期は短いですが、その代謝物である14-ヒドロキシクラリスロマイシンは、特定の細菌に対してクラリスロマイシンのほぼ2倍の活性を示します。

このような2次標準は、USP、EP（PhEur）、BPの1次標準にマルチトレーサビリティを提供します。
