Pharmacological effects:
Isotretinoic acid belongs to the first generation of tretinoic acid, which is A stereoisomer of all-trans tretinoic acid. Oral administration has anti-grease effect and special effect on severe acne. The mechanism is as follows:
1. It can reduce the sebaceous glands, inhibit the activity of sebaceous glands and reduce the secretion of sebaceous glands, so as to inhibit the reproduction of propionibacterium acacia acne which depends on the growth of lipid environment.
2. It has the function of anti-keratinization, inhibiting the excessive proliferation of epidermal cells and promoting their differentiation, and can reduce the keratinization of hair follicle mouth and sebaceous gland duct.
3. It can also affect the function of monocytes and lymphocytes, inhibit the chemotaxis of neutrophils and have anti-inflammatory activity.
4. Selectively bind the tretinoic acid nuclear receptor to play A therapeutic role. Inhibition of the proliferation of probacteriaceae acne at low doses and immunosuppression at high doses.
5. Can inhibit the formation of collagenase and gelatinase in the skin, and can inhibit the activity of ornithine decarboxylase. Induction of ornithine decarboxylase can play A major role in skin mutation, so isotretinoic acid can also inhibit the occurrence of tumors.
6. When applied locally, the action mechanism of this product is similar to that of tretinoic acid, which can induce epidermal cell proliferation, promote epidermal cell granular layer to differentiate into cuticle layer, and regulate keratinocytes in the process of abnormal keratinization of hair follicle sebum epithelium, thus playing A therapeutic role.
1. Isotretinoic acid is the first choice for refractory acne, especially for patients with severe nodular, cystic and inflammatory acne who have failed traditional treatment;
2. Generalized flat warts or verrucous epidermal dysplasia;
3. Abnormal keratotic dermatosis;
4. Cutaneous lupus erythematosus;
5. Lichen planus, sclerosing atrophic moss.
