It is widely prescribed for the treatment of severe and resistant forms of acne, including nodular acne and acne that does not respond to conventional treatments such as antibiotics or topical therapies.

• Active Ingredient: Isotretinoin 20mg per capsule.
• Indications: Severe recalcitrant nodular acne, acne conglobata, and other forms of acne prone to scarring.
• Therapeutic Goal: To induce long-term remission by addressing the underlying causes of acne.
• Prescription Status: Prescription-only due to significant potential side effects and teratogenicity.

A-CNOTREN 20mg is considered a highly effective treatment option for severe acne, but its use requires strict medical supervision and adherence to safety guidelines.

How to use A-CNOTREN 20mg

Proper usage of A-CNOTREN 20mg is critical to achieving optimal therapeutic outcomes while minimizing risks:

• Administration: Take capsules orally with meals to enhance absorption.
• Dosage Regimen: Usually prescribed at 0.5 mg/kg/day initially, which may be increased to 1 mg/kg/day depending on clinical response and tolerance.
• Duration: The treatment course generally lasts between 16 and 24 weeks, though it may be extended or repeated based on patient progress.
• Missed Doses: If a dose is missed, take it as soon as remembered unless it is close to the next scheduled dose. Avoid doubling doses.
• Monitoring: Regular follow-ups with the healthcare provider for blood tests and clinical assessments are mandatory.

Mode of Action A-CNOTREN 20mg

Isotretinoin, the active compound in A-CNOTREN 20mg, exerts its therapeutic effects through multiple mechanisms:

• Reduction of Sebum Production: Isotretinoin decreases the size and activity of sebaceous glands, significantly lowering sebum output, which reduces the oily environment that fosters acne development.
• Normalization of Follicular Keratinization: It normalizes the shedding of skin cells within hair follicles, preventing the formation of comedones (clogged pores).
• Anti-inflammatory Properties: It reduces inflammation by modulating the immune response and decreasing the presence of inflammatory cells in the skin.
• Decrease in Cutibacterium acnes: By altering the follicular environment, isotretinoin indirectly limits the proliferation of bacteria involved in acne.

Together, these actions help clear severe acne lesions and maintain remission after treatment.
