What is Retinoic Acido?

Retinoic Acido is a commonly used drug in dermatology. It is the metabolic intermediate product of vitamin A (vitamin methanol) in the body. It generally affects the growth of bone and also epithelial metabolism, can advertise the expansion and also revival of epithelial cells, as well as can inhibit the spreading and also differentiation of keratinocytes.It can restore the hyperkeratosis to normal, so it has a certain therapeutic effect on many diseases with complete keratinization, incomplete keratinization and hyperkeratosis, and can treat a variety of skin diseases. Topical application penetrates the skin quickly and can significantly increase epithelial cell turnover. This class of drugs has a strong and rapid inhibitory effect on the secretion of sebaceous glands, which can reduce the secretion of sebum. In addition, this product also has anti-tumor, promoting wound healing and anti-infection effects.

Retinoic Acido Uses

  1. Retinoic Acido (ATRA) is a ligand of retinoic acid receptor (RAR) and RetinoidX receptor (RXR), which binds to RAR and RXR as transduction factors to regulate the growth and differentiation of normal cells and tumor cells. Cytochrome P450s (CYPs) catalyze the hydroxylation of ATRA; retinoic acid guides the evolution of embryonic stem cells (embryonicstemcells) into neurons.
  2. Retinoic Acido is used in anti-keratosis drugs.
  3. Retinoic Acido, also known as retinoic acid, is the metabolic intermediate product of vitamin A in this strain, which mainly affects the growth of bone and the metabolism of epithelial cells, and has the effects of promoting epithelial cell proliferation and keratinolysis. It can also be used as an adjuvant therapeutic drug for psoriasis (psoriasis), and can also be used to treat multiple common warts and various skin diseases such as ichthyosis and keratosis follicles.

Retinoic Acido Drug Interactions

(1) There is a risk of increasing photosensitivity when used in combination with photosensitizers.
(2) Shared with detergents such as soaps, preparations containing desquamative drugs (such as benzoyl peroxide, rasocin, salicylic acid, sulfur, etc.), preparations containing ethanol, isotretinoin, etc., which may aggravate skin irritation or Dry, so it must be used with caution.
(3) Concomitant use with cimetidine, cyclosporine, diltiazem, verapamil, ketoconazole, etc., can cause an increase in the blood concentration of this product, and may lead to tretinoin poisoning.
(4) Combined use with pentobarbital, phenobarbital and rifampicin can cause the plasma concentration of this product to decrease.
(5) This item will impact the liver cytochrome P450 enzyme system, leading to adjustments in blood drug concentration.
(6) Taking oryzanol, vitamin B1, vitamin B6 and other drugs at the same time can reduce or disappear the adverse reactions such as headache caused by this product. Pharmacological effects, pharmacokinetics, pharmacodynamics, indications, drug interactions and side effects of retinoic acid commonly used in dermatology.

Pharmacological Effects of Retinoic Acid

This product can induce epidermal hyperplasia, thicken the granular layer and the spinous cell layer, and promote the epidermis by affecting K1 and K10 keratinase hydrolysis in the later stage of epidermal cell differentiation, affecting the process of filaggrin from filaggrin to filaggrin and the formation of cross-linked envelope. This product can significantly inhibit the formation of experimental acne, and remove the keratin plug by regulating the abnormal process of keratinization of the pilosebaceous epithelium, thereby preventing and eliminating acne lesions. In addition, retinoic acid can also affect the melanogenesis of melanocytes, and its effect is multi-site, and it has no effect on the activities of three types of catalytic enzymes such as tyrosine hydroxylase, dopa oxidase and dihydroxyindole oxidase. It has an inhibitory effect, thereby reducing melanin formation and skin pigmentation; it has no effect on normal human melanocyte tyrosinase activity and melanin composition.

Retinoic Acid Precautions

(1) Those who are allergic to this product, those who are allergic to vitamin A derivatives, patients with acute or subacute dermatitis, eczema-like skin diseases and pregnant women are prohibited.
(2) People with allergies should use with caution.
(3) Breastfeeding women should stop breastfeeding during the medication period, and pregnancy is strictly prohibited for women of childbearing age. Use with caution in children.
(4) This product should avoid contact with eyes and other mucous membranes (such as mouth, nose, etc.). It should not be used on skin folds and skin ulcers.
(5) If there is burning sensation, itching, redness, etc. at the medication site, the medication should be discontinued, the local medication should be washed, and a physician should be consulted if necessary.

(7) This product is not suitable for large-scale application, and the daily dosage should not exceed 20g.
(8) Do not use other drugs, cosmetics or detergents that can cause skin irritation and damage during the medication, so as not to aggravate skin reactions, increase drug absorption and cause systemic adverse reactions.
(9) Sunlight can aggravate the irritation of retinoic acid to the skin and lead to the decomposition of retinoic acid. Animal experiments suggest that retinoic acid can enhance the carcinogenicity of ultraviolet rays. Therefore, this product is best applied at night and before going to bed. Sun exposure should be avoided during the treatment process. , or use shading measures.

Pharmacokinetics of Retinoic Acid

For external use, a small amount is absorbed by the skin, and the absorption is increased when applied to a large area. About 5% of the external dose is excreted in the urine. This product is well absorbed after oral administration, and reaches the peak plasma concentration after 3 hours. After oral administration of 1 mg/kg, the plasma concentration can reach 0.3-0.5 mg/ml. After oral absorption, it is widely combined with plasma proteins, with an average elimination half-life of 0.7 hours. After a single oral dose of 40 mg, the blood drug concentration reaches the endogenous metabolic level in 7 to 12 hours. There was no accumulation in the body after repeated oral administration, but the plasma concentration decreased significantly, which may be due to the induction of cytochrome P450 enzymes, which increased the elimination rate and decreased the bioavailability. Mainly metabolized in the liver, the metabolite is glucuronide. 60% is excreted by the kidneys, and can also be excreted through the bile. The half-life of metabolites is longer than that of this product.
