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 is a lucocorticosteroid (GCS) for external use. It has a local anti-inflammatory, antipruritic, vasoconstrictive and immunosuppressive effect, however, the exact mechanisms of the anti-inflammatory effect of topical corticosteroids are not completely clear. The use of occlusive dressings enhances the effect of topical corticosteroids, as this increases their penetration into the skin itself.
Pharmacokinetics
Absorption and distribution of
When using Daivobet, 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 topical corticosteroids increases. Since a depot of the drug is created in the skin, its elimination from the skin occurs within a few days.
Metabolism and excretion
Betamethasone is metabolized in the liver and kidneys to form glucuronides and sulfoesters, excreted through the intestines and kidneys.
Indications
Chronic vulgar plaque psoriasis.
