詳細

詳細

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.
Letrozole is used for the treatment of breast cancer in hormone-dependent postmenopausal patients. The drug works by blocking the synthesis of estrogen, a causative agent for cancer.

アプリケーション

Letrozole may be used as a pharmaceutical reference standard for the determination of the analyte in biological/environmental samples and pharmaceutical formulations by various chromatography techniques.

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.

生物化学的／生理学的作用

レトロゾールは、第3世代の非ステロイド系のアロマターゼインヒビターです。アロマターゼ酵素系の競合的インヒビターであるため、アンドロゲンからエストロゲンへの変換を阻害します。レトロゾールは、この酵素のシトクロムP450サブユニットのヘムに競合的に結合することによってアロマターゼ酵素を阻害し、すべての組織においてエストロゲンの生合成を低下させます。

アナリシスノート

このような2次標準は、入手可能な場合にはUSP、EP、BPの1次標準にマルチトレーサビリティを提供します。
