Isotroin, known generically as isotretinoin, is a potent oral retinoid primarily prescribed for severe acne, particularly nodulocystic acne that has not responded to conventional treatments. Its efficacy in inducing long-term remission has been well-documented, making it a cornerstone in dermatological therapy for severe acne cases.

Mechanism of Action
Isotretinoin targets multiple pathogenic factors involved in acne development:
- Sebum Production Reduction: It significantly decreases sebum excretion by reducing the size and activity of sebaceous glands. A dose of 0.5–1.0 mg/kg/day can lead to a 90% reduction in sebum output within six weeks.
- Comedogenesis Inhibition: By normalizing the shedding of skin cells within hair follicles, isotretinoin prevents the formation of comedones, thereby reducing pore blockages.
- Anti-inflammatory Effects: It exhibits anti-inflammatory properties, reducing the redness and swelling associated with inflamed acne lesions.
Efficacy
Clinical studies have consistently demonstrated the high efficacy of isotretinoin in treating severe acne:
- Long-term Remission: A standard course of isotretinoin therapy, typically lasting four to five months, often leads to significant clearing of acne, with many patients experiencing prolonged remission.
- Low-Dose Regimens: Research indicates that low-dose isotretinoin (e.g., 20 mg/day) can be effective for moderate to severe acne, offering a favorable balance between efficacy and side effect profile. In a study, 90% of participants showed very good results with a low incidence of serious side effects.
Safety and Side Effects
While isotretinoin is highly effective, it is associated with several side effects:
- Common Side Effects: Dry skin, chapped lips, dry eyes, and nosebleeds are frequently reported. These effects are usually manageable with supportive care and typically resolve after discontinuation of therapy.
- Teratogenicity: Isotretinoin is known to cause severe birth defects if taken during pregnancy. Strict contraceptive measures are mandatory for women of childbearing potential during treatment and for a period after discontinuation.
- Psychiatric Effects: There have been reports of mood changes, including depression and, rarely, suicidal ideation. However, a direct causal relationship has not been conclusively established. Patients should be monitored for mood changes during therapy.
- Lipid and Liver Enzyme Changes: Elevations in serum lipids and liver enzymes can occur; regular monitoring through blood tests is recommended during treatment.
Considerations for Use
Due to its potential side effects, isotretinoin should be prescribed after careful consideration:
- Patient Selection: Ideal for individuals with severe, scarring acne unresponsive to other treatments.
- Monitoring: Regular follow-ups to monitor for side effects, including laboratory tests for lipid levels and liver function, are essential.
- Dosage: The standard dosage ranges from 0.5 to 1.0 mg/kg/day, with cumulative doses aiming for 120–150 mg/kg over the treatment course. Lower doses may be considered to minimize side effects, though this may require a longer treatment duration.
Conclusion
Isotretinoin remains the most effective treatment for severe acne, offering the potential for long-term remission. Its use requires careful patient selection, thorough counseling, and diligent monitoring to balance its benefits against potential risks. When appropriately managed, isotretinoin can significantly improve the quality of life for individuals suffering from severe acne.
