Adapalene (Adapalene) – instructions for use, description of the pharmacological action, indications for use, dosage and mode of administration, contraindications, side effects
Characteristics: A synthetic analogue of retinoic acid, a derivative of naphthoic acid. The agent for the treatment of acne.
A white or almost white powder. Insoluble in tetrahydrofuran, slightly soluble in ethanol, practically insoluble in water. Molecular weight 412,53.
The existing dosage forms of adapalene 0.1% gel on aqueous basis, 0.1% cream, 0.1% solution. Gel 0.1% and 0.1% cream are registered in USA.
Mode of action
Pharmacology: Mode of action – komedonoliticheskoe, anti-inflammatory. Adapalene ; chemically stable, retinoid-like compound. Studies of the biochemical and pharmacological profile of adapalene demonstrated that he is a modulator of the processes of cell differentiation, keratinization (cornification) and inflammation are involved in the development of acne vulgaris.
The exact mechanism of action of adapalene is unknown, but it is believed that when applied topically it normalizes the differentiation of follicular epithelial cells and keratinization, preventing the formation of microcomedo like retinoid action. Unlike retinoic acid, adapalene binds to a specific retinoic acid nuclear receptors (retinoic acid receptors, RARs) and does not interact with the so-called cytosolic binding proteins retinoic acid (cytosolic retinoic acid binding proteins, CRABPs).
The selectively binding to receptors on RARgamma nuclear membrane of keratinocytes, adapalene enhances keratinocyte differentiation, reduces the « entanglement » keratinocyte in the mouth of tallow – hair follicles and accelerates their desquamation. It has komedonoliticheskim / antikomedogennym action. It does not induce epidermal hyperplasia. Does not cause irritation expressed as RARalfa does not interact with, the stimulation of which leads to the appearance of skin dryness and flaking. Anti-inflammatory effect, influencing the inflammatory factors. Increases the skin’s sensitivity to UV radiation.
The therapeutic effect begins to appear after 1 – 2 weeks, sustained improvement is usually seen after 8 – 12 weeks.
Absorption of adapalene through human skin is low. In controlled clinical trials after prolonged topical administration of adapalene 0.1% gel or a 0.1% solution in the blood plasma of patients were found only trace amounts of substances (< 0,25 ng / ml). The pharmacokinetic study 6 patients with acne (acne) when applied 2% cream 0.1 g per 1000 cm ^ 2 surface skin with acne 1 once daily for 5 days adapalene not quantitatively determined in plasma samples from a single patient (detection limit = 0.35 ng / ml). It eliminated primarily by biliary.
carcinogenicity, mutagenicity, effects on fertility
In animal studies the topical application of doses of adapalene 0.3; 0.9 and 2.6 mg / kg / day (gel solution) or 0.4; 1.3 and 4.0 mg / kg / day (cream) in the mouse carcinogenicity is not revealed. The ingestion (in rats) at a dose of 0.15; 0.5 and 1.5 mg / kg / day (approximately 4 – 75 times the maximum daily dose for humans when applied topically) reported an increase incidence of adenoma cells and follicular thyroid carcinoma in female rats and benign and malignant forms of pheochromocytoma adrenals in male rats.
Studies have not been carried out fotokantserogennosti adapalene. However, animal studies show that other pharmacologically similar drugs (such as topical retinoids) increase the risk of carcinogenicity when used in conjunction with UV irradiation or exposure to sunlight. These results were observed in the experiment under certain conditions, but not all test – systems. Although the significance of these data for humans is unclear, and patients should avoid UV exposure, and exposure to the sun.

Studies of the effect of adapalene on reproduction and fertility in rats when administered orally in doses up to 20 mg / kg / day (80 times the MRDCH in mg / m ^ 2) did not reveal any effect on reproduction or fertility in F_0 male or females. Also, did not interfere with the growth, development and reproductive function F_1 generation.
Pregnancy. Teratogenic effects. There were no teratogenicity in rats when used orally in doses of adapalene from 0.15 to 5.0 mg / kg / d (up to 120 times the MRDC when applied topically).
However, the oral administration of animal doses> = 25 mg / kg / day leads to teratogenic effects in rats and rabbits.
Teratological study of cutaneous application of adapalene in animals (rats and rabbits) have not been completed. At doses of 0.6; 2.0 and 6.0 mg / kg (up to 150 times higher when applied topically MRDC) foetotoxic action is detected, but fixed minimum increase in the number of edges in the offspring rats.
In two controlled (control ; cream base) clinical studies, adapalene 0.1% in the form of cream included patients 12 – 30 years with mild to moderate acne; Patients were instructed on the use of cream 1 time a day at bedtime for 12 weeks.
