Indications ▼
Psoriasis (plaque type, hyperkeratotic)
Seborrheic dermatitis
Thickened, scaly, or hyperkeratotic lesions of the skin
Other corticosteroid-responsive dermatoses requiring keratolytic effect
Mechanism & Pharmacokinetics ▼
Mechanism: Betamethasone reduces inflammation, redness, and itching through glucocorticoid receptor-mediated anti-inflammatory action. Salicylic acid softens and removes keratin, promoting exfoliation and enhancing corticosteroid penetration.
Pharmacokinetics: Topical absorption of betamethasone varies with skin thickness and area; systemic absorption is minimal but may occur with prolonged use. Salicylic acid acts locally; systemic absorption is negligible at recommended doses.
