General description
Isotretinoin is a vitamin A derivative, obtained from the isomerization of retinoic acid in the body. It is therapeutically used to treat severe recalcitrant nodular acne. It is also reported to exhibit anti-inflammatory and anti-tumor activities.
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.
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.
Application
Isotretinoin may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using reversed-phase high-performance liquid chromatography.
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.
Biochem/physiol Actions
13-cis-Retinoic acid (RA) has anti-inflammatory and anti-tumor action. The action of RA is mediated through RAR-β and RAR-α receptors. RA attenuates iNOS expression and activity in cytokine-stimulated murine mesangial cells. It induces mitochondrial membrane permeability transition, observed as swelling and as a decrease in membrane potential, and stimulates the release of cytochrome c implicating mechanisms through the apoptosis pathway. These activities are reversed by EGTA and cyclosporin A. RA also increases MMP-1 protein expression partially via increased transcription.
Analysis Note
These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
Other Notes
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
