Vectical (calcitriol) works by influencing the activity of skin cells and immune responses in the affected areas. When applied to the skin, calcitriol helps regulate certain skin cell activities involved in psoriasis. In people with plaque psoriasis, skin cells grow and divide more rapidly than normal. This accelerated cell turnover leads to a buildup of immature skin cells on the surface, forming the thick, scaly plaques characteristic of the condition.
Its effects include:
1. Slowing Excess Skin Cell GrowthVectical helps reduce the unusually rapid production of skin cells seen in psoriasis. Slowing this process can help limit the buildup of thick plaques on the skin.
2. Supporting Normal Skin Cell MaturationIn psoriasis, many skin cells reach the surface before they fully mature. Calcitriol promotes more normal development and differentiation of skin cells, contributing to healthier skin structure.
3. Modulating Inflammatory ActivityPsoriasis involves immune-related inflammation in the skin. Calcitriol has been shown to influence inflammatory pathways and immune signaling in skin tissue, potentially reducing redness, irritation, and scaling.
These effects may improve the appearance of plaque and reduce symptoms such as scaling and irritation. The exact mechanism is not fully understood, but it is related to the regulation of skin cell growth and immune activity.
Vectical is FDA-approved to treat:
