Psoriasis, also known as psoriasis, is clinically treated with a number of creams, the overall of which are broadly divided into two categories: firstly, hormonal; secondly, non-hormonal. Hormonal creams include strong hormones, such as halometasone ointment; medium-acting hormones, such as hydrocortisone butyrate ointment or fluticasone propionate ointment or mometasone furoate ointment; and weak hormones, such as dextran ointment. And non-hormones include calcium-regulated phosphatase inhibitors, such as 0.03% tacrolimus cream or 0.1% tacrolimus cream; and vitamin D3 derivatives, such as carbotriol ointment or tacrolimus ointment.
