Topical medications for psoriasis include glucocorticoid drugs, calcium-modulated neural phosphatase inhibitors, retinoic acid preparations, vitamin D3 derivatives and so on. 1. Glucocorticosteroid drugs: Glucocorticosteroid drugs can be chosen during acute attacks, such as tretinoin cream, betamethasone cream and so on. However, long-term use will cause local skin atrophy, capillary dilatation, etc., and it is not suitable for use on the face, and pustular and erythrodermic psoriasis may also appear after stopping the drug. 2. Calcium-modulated neural phosphatase inhibitors: for the scalp, genitals and folds of the skin, you can use tacrolimus ointment, pimecrolimus cream, but long-term application of large amounts will increase the risk of skin cancer. 3. Vitamin A acid preparations: in case of plaque-type psoriasis, you can choose vitamin A acid preparations, such as isotretinoin and tazarotene, which may cause adverse reactions such as itching, erythema, burning and so on after using the medication. 4. Vitamin D3 derivatives: the more commonly used ones are calbotriol ointment, tacalcitol ointment, etc. However, it should be noted that they can not be used on the face and the parts of skin folds. All of the above medications should be used under the guidance of a doctor, avoid self-medication, so as not to cause adverse consequences.
