Synthetic retinoids in dermatology.

E H Heller, N J Shiffman

    Canadian Medical Association Journal
    |May 15, 1985
    PubMed
    Summary

    Retinoids, synthetic vitamin A derivatives, offer effective treatments for severe skin conditions like acne and psoriasis. While generally safe, their teratogenic nature limits use in women of childbearing potential.

    Area of Science:

    • Dermatology
    • Pharmacology
    • Oncology

    Background:

    • Vitamin A (retinol) has known therapeutic potential for skin diseases but is limited by toxicity.
    • Development of synthetic retinoids offers safer alternatives for treating resistant dermatological conditions.

    Purpose of the Study:

    • To evaluate the efficacy of non-toxic synthetic retinoids in treating various skin diseases.
    • To explore the potential antineoplastic effects of retinoids in epithelial cancers.

    Main Methods:

    • Clinical application of synthetic retinoids, specifically isotretinoin and etretinate.
    • Observation of treatment outcomes in patients with acne, psoriasis, and other keratinization disorders.
    • Investigation into the mechanisms of retinoid action on epidermal tissues and polyamines.

    Main Results:

    • Isotretinoin demonstrated high efficacy in cystic and conglobate acne.
    • Etretinate proved useful in severe psoriasis and other keratinization disorders.
    • Retinoids show potential for epithelial cancer prevention and treatment.

    Conclusions:

    • Synthetic retinoids provide effective therapeutic options for severe and resistant skin diseases.
    • Retinoids modulate epidermal differentiation and proliferation, with polyamine influence a potential mechanism.
    • Teratogenicity necessitates caution in prescribing retinoids to women of childbearing potential due to persistence in the body.
