3. Mechanism of Action (MOA)
Calcipotriene is a Vitamin D receptor (VDR) agonist.
Key actions:
Binds to VDR in keratinocytes
Regulates gene transcription involved in:
Cell proliferation ↓
Cell differentiation ↑
Suppresses hyperproliferation of epidermal cells
???? Result:
Normalizes skin cell turnover
Reduces plaque formation and scaling
4. Pharmacokinetics (ADME)
Absorption: Minimal systemic absorption via intact skin
Distribution: Local skin layers; negligible plasma levels
Metabolism: Hepatic metabolism if systemically absorbed
Elimination: Biliary and renal (metabolites)
Half-life: Not clinically significant systemically due to low absorption
⚠️ Systemic absorption increases if:
Large surface area treated
Broken skin
Excessive dosing
5. Dosage & Administration
Cream/Ointment (0.005%)
Apply thin layer once or twice daily
