Signature

Product Overview

Signatret is a prescription medication containing Isotretinoin, a potent vitamin A-derived retinoid. Specifically designed for treatment-resistant severe nodular acne, this oral capsule formulation addresses acne’s root causes by regulating sebum production, reducing inflammation, and preventing pore blockages. Its systemic action provides lasting improvements in skin clarity and texture for patients with severe acne conditions.

Therapeutic Indications

This medication is prescribed for severe nodular acne cases unresponsive to conventional therapies. It effectively treats deep, painful subcutaneous nodules while preventing acne scarring. Signatret demonstrates particular efficacy in cases involving excessive sebum production, persistent inflammation, and recurrent comedone formation.

Administration Guidelines

For optimal absorption and tolerance:
• Take capsules with meals (preferably fatty foods)
• Maintain consistent dosing times
• Swallow whole with water
• Never crush or chew capsules
The treatment duration typically spans 15-20 weeks, with dosage adjustments based on clinical response and tolerance. If a dose is missed, take it as soon as remembered unless nearing the next scheduled dose.

Mechanism of Action

Isotretinoin exerts multifactorial anti-acne effects through:
1. Sebaceous gland suppression (up to 90% reduction in sebum production)
2. Normalization of follicular keratinization
3. Anti-inflammatory action via modulation of immune responses
4. Inhibition of Cutibacterium acnes proliferation
These combined actions result in comprehensive acne clearance and prevention of new lesion formation.

Dosage Protocol

Standard dosing follows these parameters:
• Initial dose: 0.5 mg/kg/day
• Maintenance dose: 0.5-1 mg/kg/day
• Maximum dose: 2 mg/kg/day
Dosage is typically divided into two daily administrations. Treatment continues until reaching cumulative dose of 120-150 mg/kg, with regular clinical evaluations every 4 weeks.
