General description

This product is provided as delivered and specified by the issuing Pharmacopoeia.

Isotretinoin, a vital isomer of vitamin A, is implicated in the treatment of severe recalcitrant nodular acne disorder. It is the only drug known to operate against the major pathogenic factors of acne. It serves to diminish the sebaceous gland activity, thereby resulting in the correction of keratinization defect.

Application

Isotretinoin may be used as an EP reference standard for the determination of the analyte in pharmaceutical formulations by various chromatography techniques.

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.

Despite its potent biologic effect on human sebocytes, 13-cis retinoic acid exhibits low binding affinity for cellular retinoic acid binding proteins and nuclear retinoid receptors. Hence, 13-cis retinoic acid may represent a pro-drug possibly acting through all-trans isomerization. In this
