Xamiol, gel 60 g

Pharmacodynamics

Calcipotriol is a synthetic analog of the active metabolite of vitamin D. It causes inhibition of keratinocyte proliferation and accelerates their morphological differentiation.

Betamethasone is a glucocorticosteroid (GCS) for external use; it has local anti-inflammatory, antipruritic, vasoconstrictor and immunosuppressive effects, but the exact mechanisms of anti-inflammatory action of external steroids are not fully understood. The use of occlusive dressings enhances the effect of GCS, as it increases their penetration into the skin.

Pharmacokinetics

When using XAMIOL®, the absorption of calcipotriol and betamethasone through intact skin is less than 1%. When the drug is applied to psoriatic plaques and under occlusive dressings, absorption of the external GCS is increased. Since a depot of the drug is created in the skin, it is eliminated from the skin within a few days. Betamethasone is metabolized in the liver and kidneys to form glucuronides and sulfoesters, excretion is through the intestine and kidneys.

Indications

Psoriasis of the scalp.

Mild to moderate psoriasis of other parts of the body.

The maximum daily dose should not exceed 15 g; the maximum weekly dose should not exceed 100 g. Recommended duration of treatment course is 4 weeks for psoriasis of the scalp and 8 weeks for lesions of other parts of the body. Area of application of the drug should not exceed 30% of the body surface.

The drug should be left on the skin overnight or during the day for optimal therapeutic effect. Repeated use of Xamiol® is possible under a physician’s supervision.

Special Instructions

Do not use the product on mucous membranes.

Perhaps use with caution when applied to the face and genitals.

Inadvertent contact with the eyes may cause undesirable adverse reactions in the form of eye and facial skin irritation and conjunctivitis. If accidental contact occurs, the eyes should be rinsed with running water.

Wash hands after applying the drug.

If secondary infections develop, antimicrobial therapy should be prescribed. Discontinuing treatment of psoriasis with topical GCS drugs may be associated with the risk of generalized pustular psoriasis and withdrawal effects. Therefore, it is necessary to continue clinical monitoring of the patient after discontinuation of such treatment.

During treatment with XAMIOL®, it is recommended that the patient limit or avoid excessive exposure to natural or artificial sunlight. Calcipotriol (and products containing it) should only be used topically in combination with ultraviolet light exposure when the treating physician determines the risk of undesirable side effects is justified.

CAMIOL® contains butylhydroxytoluene (E321) which can cause local skin reactions (e.g., contact dermatitis) or irritation of the eyes and mucous membranes.

In order to achieve optimal therapeutic effect, it is not recommended to shower/bath or wash hair (in case of scalp lesions) immediately after using the product.
