Calcipotriene

Calcipotriene Topical Solution, 0.005% (Scalp Solution) is indicated for the topical treatment of chronic, moderately severe psoriasis of the scalp. The safety and effectiveness of topical calcipotriene in dermatoses other than psoriasis have not been established.

Calcipotriene Topical Solution, 0.005% (Scalp Solution), is contraindicated in those patients with acute psoriatic eruptions or a history of hypersensitivity to any of the components of the preparation. It should not be used by patients with demonstrated hypercalcemia or evidence of vitamin D toxicity.

Avoid contact with the eyes or mucous membranes. Discontinue use if a sensitivity reaction occurs or if excessive irritation develops on uninvolved skin areas. Drug product is flammable. Keep away from open flame.

Pregnancy Teratogenic Effects Pregnancy Category C Studies of teratogenicity were done by the oral route where bioavailability is expected to be approximately 40-60% of the administered dose. Increased rabbit maternal and fetal toxicity was noted at 12 μg/kg/day (132 μg/m 2 /day). Rabbits administered 36 μg/kg/day (396 μg/m 2 /day) resulted in fetuses with a significant increase in the incidences of pubic bones, forelimb phalanges, and incomplete bone ossification.

In a rat study, oral doses of 54 μg/kg/day (318 μg/m 2 /day) resulted in a significantly higher incidence of skeletal abnormalities consisting primarily of enlarged fontanelles and extra ribs. The enlarged fontanelles are most likely due to calcipotriene's effect upon calcium metabolism. The maternal and fetal calculated no-effect exposures in the rat (43.2 μg/m 2 /day) and rabbit (17.6 μg/m 2 /day) studies are greater than the expected human systemic exposure level (0.13 μg/m 2 /day) from dermal application.

There are no adequate and well-controlled studies in pregnant women. Therefore, Pellix™ Topical Solution, 0.005% (Scalp Solution), should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
