Viaminati Powder Usage and Synthesis.

Viamin ester is a derivative of retinoic acid, with a structural formula similar to all-trans retinoic acid, and a mechanism of action more similar to that of 13-cis-retinoic acid and aromatic retinoic acid, but with milder side effects than that of all-trans retinoic acid. Oral administration has the function of regulating and controlling the differentiation and growth of epithelial cells, inhibiting keratinisation, reducing sebum secretion, inhibiting the keratinisation process of keratin-forming cells, restoring keratinisation abnormality to normal, inhibiting the growth of Propionibacterium acnes, and regulating the immune and anti-inflammatory effects.

Uses and functions of  Viaminati.

Viamine ester is the first generation of retinoic acid drugs developed and produced by our country, which is used for the treatment of moderate to severe acne, and also has certain efficacy in ichthyosis, psoriasis, mossy skin diseases and certain keratotic abnormalities of skin diseases. Vitamin E capsules are widely used in the treatment of acne, and are effective in the treatment of moderate to severe acne, including acne with nodules and cysts, as acne has a higher incidence in adolescent students and middle-aged women of childbearing age who are in the critical stage of growth and development.

Pharmacological Effects of Viaminati.

Viamin ester is a derivative of retinoic acid, the structural formula is similar to all-trans retinoic acid, the mechanism of action is more similar to 13-cis-retinoic acid and aromatic retinoic acid, but the side effects are milder than those of all-trans retinoic acid.

Oral administration has the function of regulating and controlling the differentiation and growth of epithelial cells, inhibiting keratinisation, reducing sebum secretion, inhibiting the keratinisation process of keratin-forming cells, restoring keratinisation abnormality to normal, inhibiting the growth of Propionibacterium acnes and regulating the immune and anti-inflammatory effects.

It also has the effect of removing wrinkles and folds, reducing pigmentation and increasing skin elasticity.

Most of the product is absorbed through the intestinal tract after oral administration, and excreted by urine and stool after metabolised by the liver and gallbladder. In healthy men, a single oral dose of 10mg of this product on an empty stomach, the time to peak was 2.612±0.778 hours, the peak blood concentration was 17.496±8.992μg/ml, and the half-life (t1/2) was 2.378±0.871 hours.

1. Combined with isotretinoin and tetracycline, it can cause "pseudotumour of the brain", resulting in increased cranial pressure, headache, visual impairment.

2. Combined with vitamin A, can produce similar symptoms of vitamin A overdose, should not be used together.

3. Combined with methotrexate, it can increase the blood concentration of the latter and lead to poisoning.

Production method of Viaminati Powder.

In the reaction tank put 240kg dichloromethane, 17kg (105.4mol) benzocaine, 20kg triethylamine, and then 42kg vinyl chloride (131.7mol) diluted with the appropriate amount of dichloromethane, at -3 ℃ ~ 5 slowly added to the above reaction tank, add the end of the reaction, the reaction at 30 ~ 35 ℃ for 2 hours, distillation under reduced pressure to the tank precipitated a large number of solids, add 60kg 95% ethanol, stirring, cooling precipitation crystal, centrifugation, washing, drying, that is, the vinylamine ester finished product 48.9kg, yield 83.0%, purity 99.0%. 60kg of 95% ethanol, stirring, cooling precipitation, centrifugation, washing, drying, viamine ester 48.9kg, yield 83.0%, purity 99.0%.
