Mechanism Of Action and Pharmacodynamic Effects Click here for help
Isotretinoin has a low affinity for retinoic acid receptors (RAR) and retinoid X receptors (RXR), but metabolites may act as agonists of these nuclear receptors [1]. Activation of RAR modulates the expression of genes essential for regulating cell proliferation and differentiation. Isotretinoin may also posess immunomodulatory and anti-inflammatory activities and has been demonstrated to inhibit ornithine decarboxylase, an action likely to decrease polyamine synthesis and keratinization.
