Mechanism & Pharmacology

Simplified explanation

Understanding how isotretinoin works can seem complex, but it's quite straightforward. As a systemic retinoid, isotretinoin operates by targeting the skin's oil production, something known to play a role in acne formation. Think of it as a deep-cleaning agent for your skin. It reduces the size and activity of sebaceous (oil) glands, effectively limiting sebum production, which lowers the chances of clogged pores. This treatment also helps to renew skin cells more rapidly, preventing the buildup of dead skin that can lead to acne breakouts. It modulates the skin’s immunity and reduces inflammation, making it a powerful ally in the fight against severe acne.

Clinical terms

In a clinical setting, isotretinoin, also referred to as 13-cis-retinoic acid, is classified under the ATC code D10BA01. It is indicated for treatment of severe recalcitrant nodular acne, particularly ineffective with conventional therapies. Formulations typically consist of hard capsules available in doses of 5 mg, 10 mg, 20 mg, and 40 mg, with dosing based on a patient's weight, often starting at 0.5 mg/kg/day and can increase to 1 mg/kg/day based on clinical response. Potential side effects include xerosis, cheilitis, and elevations in liver enzymes and triglycerides. Isotretinoin is contraindicated in pregnancy due to teratogenic effects and requires careful monitoring of lipid levels during therapy.

Indications & Off-Label Uses in Canada

Approved indications

Isotretinoin is approved by Health Canada for severe recalcitrant nodular or cystic acne, unresponsive to conventional treatments. The DIN associated with isotretinoin in Canada is available under brand names like Epuris, which is widely recognized in the pharmacy sector. Dosage regimens typically span 16 to 24 weeks, with monitoring for side effects and effectiveness essential throughout the treatment duration.

Common off-label practices

While isotretinoin's primary indication is for acne, Canadian physicians often explore off-label uses based on individual patient needs. These include treatment for conditions like rosacea or severe cysts. Though not specifically approved, anecdotal evidence suggests that isotretinoin may help with stubborn acne scars. Regulatory guidelines emphasize the necessity for patient education on potential risks, particularly concerning teratogenicity in women of childbearing age.

Key Clinical Findings
