Cystic Acne Treatment Pharmaceutical Raw Materials INN / Isotrex / Isotretinoin 4759-48-2

Function

1.Isotretinoin's main indication is for the treatment of severe cystic acne vulgaris. Many dermatologists also support its use for treatment of lesser degrees of acne that prove resistant to other treatments, or that produce physical or psychological scarring.

2.It is also somewhat effective for hidradenitis suppurativa and some cases of severe acne rosacea. It can also be used to help treat harlequin ichthyosis, lamellar ichthyosis and is used in xeroderma pigmentosum cases to relieve keratoses. Isotretinoin has been used to treat the extremely rare condition fibrodysplasia ossificans progressiva. It is also used for treatment of neuroblastoma, a form of nerve cancer.

3.Isotretinoin therapy has furthermore proven effective against genital warts in experimental use, but is rarely used due to potentially severe side effects. In a small-scale study, low dose oral isotretinoin showed considerable efficacy;

4.Isotretinoin may represent an efficacious and safe alternative systemic form of therapy for RCA of the cervix. Not many studies have been conducted to further confirm its effectiveness. In most countries this therapy is currently unapproved and only used if other therapies failed.

Medical uses

Isotretinoin is used primarily for severe cystic acne and acne that has not responded to other treatments.Many dermatologists also support its use for treatment of lesser degrees of acne that prove resistant to other treatments, or that produce physical or psychological scarring.

Mechanism of Action

Isotretinoin is the only therapy that impacts on all of the major aetiological factors implicated in acne. It achieves this remarkable efficacy by influencing cell-cycle progression, cellular differentiation, cell survival and apoptosis.1-7 It results in a significant reduction in sebum production, influences comedogenesis, lowers surface and ductal P. acnes and has anti-inflammatory properties.

A dose of 0.5-1.0 mg/kg/day dramatically reduces sebum excretion by the order of 90% within 6 weeks. Unlike tretinoin (all-trans retinoic acid), isotretinoin has little or no ability to bind to cellular retinol-binding proteins or retinoic acid nuclear receptors (RARs and RXRs) but may act as a pro-drug that is converted intracellularly to metabolites that are agonists for RAR and RXR nuclear receptors.
