A-CNOTREN 10mg Capsules (Soft Gelatin)

What is A-CNOTREN 10mg

A-CNOTREN 10mg is a prescription-only oral medication containing Isotretinoin, a potent retinoid derived from vitamin A. It is primarily used to treat severe, recalcitrant nodular acne that has not responded to conventional therapies, including systemic antibiotics and topical agents.

• Formulation: Soft gelatin capsules, each containing 10mg of isotretinoin.
• Indications: Severe nodular acne, acne conglobata, and cases at risk of permanent scarring.
• Mechanism: Reduces sebaceous gland size and sebum production, inhibits follicular keratinization, and exhibits anti-inflammatory properties.
• Manufacturer: PHARMATHEN S.A.

Due to its teratogenic potential, isotretinoin is subject to strict regulatory controls and requires enrollment in risk management programs like iPLEDGE in the U.S. or equivalent programs in other countries.

How to use A-CNOTREN 10mg

Proper administration of A-CNOTREN ensures maximum efficacy and minimizes adverse effects.

• Dosage: Typically initiated at 0.5 mg/kg/day, divided into one or two doses. Depending on patient response and tolerance, the dose may be adjusted up to 1 mg/kg/day.
• Administration: Take capsules with food to enhance absorption. Swallow whole; do not chew or crush.
• Duration: A typical course lasts 16–24 weeks. Acne may continue to improve for up to 8 weeks after discontinuation.
• Missed Dose: If a dose is missed, take it as soon as remembered unless it's close to the next scheduled dose. Do not double up doses.

Regular follow-ups with your healthcare provider are essential to monitor response and adjust dosing as needed.

Mode of Action A-CNOTREN 10mg

Isotretinoin targets multiple pathogenic factors involved in acne development:

• Sebum Production: Significantly reduces the size and output of sebaceous glands, leading to decreased sebum production.
• Follicular Keratinization: Normalizes the differentiation of follicular epithelial cells, preventing comedone formation.
• Anti-inflammatory Effects: Inhibits inflammatory responses by reducing the activity of neutrophils and monocytes.
• Antibacterial Activity: Indirectly reduces the proliferation of Cutibacterium acnes by altering the follicular environment.

These combined actions make isotretinoin highly effective in treating severe forms of acne.

A-CNOTREN 10mg Interactions A-CNOTREN 10mg

Isotretinoin can interact with various medications, potentially altering its efficacy or increasing the risk of adverse effects:

• Vitamin A Supplements: Concurrent use can lead to hypervitaminosis A; avoid supplementation.
• Tetracyclines: Combined use increases the risk of pseudotumor cerebri (benign intracranial hypertension); avoid concomitant use.
• Progestin-only Contraceptives: Efficacy may be reduced; use additional or alternative contraceptive methods.
• Phenytoin: May increase the risk of bone loss; monitor bone health.
• Systemic Corticosteroids: Concurrent use may exacerbate osteoporosis; use with caution.
• Alcohol: Can exacerbate hypertriglyceridemia; limit intake.

Always inform your healthcare provider of all medications and supplements you are taking to manage potential interactions effectively.

Dosage of A-CNOTREN 10mg

Dosage should be individualized based on patient weight, severity of acne, and tolerance:

• Initial Dose: 0.5 mg/kg/day, divided into one or two doses with meals.
• Maintenance Dose: May be adjusted up to 1 mg/kg/day based on response and side effects.
• Cumulative Dose: A total cumulative dose of 120–150 mg/kg over the treatment course is associated with prolonged remission.

Regular monitoring of lipid profiles, liver function tests, and complete blood counts is recommended during treatment.
