Mechanism of Action
Isotretinoin is a retinoid, which when administered at the recommended dosage, inhibits sebaceous gland function and keratinization. Clinical improvement in nodular acne patients occurs in association with a reduction in sebum secretion. The decrease in sebum secretion is temporary and is related to the dose and duration of treatment with isotretinoin capsules and reflects a reduction in sebaceous gland size and an inhibition of sebaceous gland differentiation. The exact mechanism of action of Absorica in the treatment of severe recalcitrant nodular acne is unknown.
