Isotretinoin Powder Usage and Synthesis.

Isotretinoin Powder is a first-generation retinoic acid, a stereoisomer of all-trans retinoic acid. It has an anti-seborrhoeic effect when taken orally and is particularly effective in severe acne. As a vitamin A analogue, 

Isotretinoin Raw Materials has a strong and rapid inhibition of the proliferation and differentiation process of skin glandular cells, which is highly effective in severe nodular cystic acne.Isotretinoin CAS 4759-48-2 is better absorbed gastrointestinally and ineffective for topical application. 

Isotretinoin Powder is used for severe acne, cystic acne, and party acne that have not been treated with other medications, and is also effective in skin disorders such as rosacea, ichthyosis, follicular keratosis, and hairy red chaff rash.

Uses and functions of Isotretinoin Powder.

• 1. Isotretinoin is the drug of choice for refractory acne, especially for patients with severe nodular, cystic, and inflammatory acne that has failed traditional treatment;
• 2. generalised flat warts or warty epidermal dysplasia;
• 3. Keratosis pilaris;
• 4. Cutaneous lupus erythematosus;
• 5. lichen planus, sclerosing atrophic moss.

Pharmacological Effects of Isotretinoin Powder.

Isotretinoin is a first-generation retinoic acid, a stereoisomer of all-trans retinoic acid. It has anti-oil effect when taken orally and has special therapeutic effect on severe acne.

The mechanism of action is as follows:

• ① It has the effect of shrinking the sebaceous glands, inhibiting the activity of sebaceous glands, and reducing the secretion of sebaceous glands, thus inhibiting the reproduction of Propionibacterium acnes, which relies on the lipid environment for growth.
• ② It has the effects of antikeratinisation, inhibiting the over-proliferation of epidermal cells and promoting their differentiation, which can reduce the keratinisation of the follicular opening and sebaceous gland ducts.
• 
• ③It can also affect the function of monocytes and lymphocytes, inhibit the chemotaxis of neutrophils and have anti-inflammatory activity.
• (iv) Selectively binds to retinoic acid nuclear receptors and exerts therapeutic effects. It inhibits the proliferation of Acinetobacter short rod bacillus and has immunostimulatory effect at low dose and immunosuppressive effect at high dose.
• ⑤ Inhibits the formation of collagenase and gelatinase in the skin and inhibits the activity of ornithine decarboxylase. Since the induction of ornithine decarboxylase can play a major role in skin mutations, isotretinoin can also inhibit tumourigenesis.
• (6) When used topically, the mechanism of action of this product is similar to that of retinoic acid, which can induce epidermal cell proliferation, promote the differentiation of the granular layer of epidermal cells to the stratum corneum, and regulate the follicular sebaceous epithelium to keratinise the abnormal process of keratinous plugs, so as to play a therapeutic role.
