Pharmacological action
Pharmacodynamics
Calcipotriol is a synthetic analogue of the active metabolite of vitamin D. It inhibits the proliferation of keratinocytes and accelerates their morphological differentiation.
Betamethasone – a glucocorticosteroid (GCS) for external use has a local anti-inflammatory, antipruritic, vasoconstrictive and immunosuppressive effect, however, the exact mechanisms of the anti-inflammatory effect of steroids for external use are not fully understood. The use of occlusive dressings enhances the effect of corticosteroids, as this increases their penetration into the skin.
Pharmacokinetics
With the use of XAMIOL ®, the absorption of calcipotriol and betamethasone through intact skin is less than 1%. When applying the drug to psoriatic plaques and under occlusive dressings, the absorption of the external corticosteroids increases. Since a depot of the drug is created in the skin, its elimination from the skin occurs within a few days. Betamethasone is metabolized in the liver and kidneys to form glucuronides and sulfoesters, excretion is carried out through the intestines and kidneys.
Indications
Psoriasis of the scalp. Psoriasis of mild to moderate severity of other parts of the body.
Use during pregnancy and lactation
During pregnancy, XAMIOL ® is used only if the expected benefits to the mother outweigh the potential risk to the fetus.
If it is necessary to use the drug during lactation, it is recommended to abandon breastfeeding.

Side effects
Side effects are classified by frequency of occurrence: most common> 1/10
frequent> 1/100 and <1/10 infrequent> 1/1000 and <1/100 rare> 1/10000 and < 1/1000 is very rare <1/10000. Eye disorders: Infrequent – eye irritation. From the skin and appendages of the skin: frequent – itching infrequent – rash, burning sensation, pain, irritation, dermatitis, exacerbation of psoriasis, folliculitis, dry skin, acne, pustular psoriasis. Calcipotriol can cause local skin irritation, itching, burning and tingling sensation, dry skin, erythema, rash, dermatitis, eczema, exacerbation of psoriasis, hypersensitivity and photosensitivity reactions, including very rare cases of angioedema and facial edema. The prolonged external use of betamethasone (dipropionate) is associated with the development of skin atrophy, telangiectasias, striae, folliculitis, hypertrichosis, perioral dermatitis, allergic contact dermatitis, depigmentation, colloid skin degeneration, as well as an increased risk of developing generalized pustular psoriasis. Systemic reactions: associated with the use of calcipotriol (very rare) – hypercalcemia or hypercalciuria associated with the use of betamethasone (rare, but sometimes severe, especially with prolonged use, on large surfaces and when using occlusive dressings) – suppression of adrenal cortex, cataracts, infections , increased intraocular pressure. Systemic reactions occur more often when applying the drug under occlusive dressings and when applied to thin skin and skin folds, as well as during prolonged treatment when applied to large areas of the skin. Drug Interaction Not known. Overdose Symptoms: Increased blood calcium levels, when drug is discontinued, rapidly suppresses the function of the pituitary-adrenal system with the development of reversible secondary adrenal insufficiency.
