Before knowing how to cure psoriasis, it is important to know what psoriasis is.
Psoriasis is a common inherited condition characterized by eruption of circumscribed, discrete and confluent, reddish, silvery-scaled maculopapules.
Psoriasis occurs as small spots anywhere on the body or it involves the large areas.
The rapid growth of skin cells causes red scaly psoriatic patches on the skin. However, the exact cause of this rapid skin growth is unknown. The lesions will be seen mostly on the scalp, trunk, elbows, and knees.
Once you start to have psoriasis, it will remain forever. It will be very itchy, red, tender, sore, and cracked. Psoriasis can come and go on its own with no reason. No blood test is available for psoriasis. Skin biopsy is sometimes helpful to know the characteristics of psoriasis.
Psoriasis does not spread to other areas. It is persistent with long periods of remission. Even though there is no cure for psoriasis, there are number of drugs and treatments to control psoriasis.
Depending on the location, severity, and history of psoriasis, treatment will be determined in each individual. Therapy is demarcated to topical drugs, if the psoriasis is in minimal stage.
On the other hand, if the psoriasis is moderate to widespread, ultraviolet light therapy with topical drugs will be used.
In case, if the topical and ultraviolet light therapy is not successful, systemic and oral drugs will be combined to ultraviolet light to affect the psoriasis (photochemotherapy or PUVA therapy).
If the psoriasis is very severe and unresponsive to the above, strong doses of oral medications will be given to help slow the rapid growth of skin cells. Oral drugs will have major side effects and some are very dangerous. All these drugs can only treat the symptoms, but cannot cure psoriasis.
Listed below are some of the main treatments that help cure psoriasis to some extent:
Steroid Creams help to reduce the plaques and inflammation. Nonetheless, when you stop the treatment, the symptoms return and increase. With these steroid creams, the skin may become thin.
For moderate psoriasis, ointments with vitamin D derivative are recently developed to treat, but this may cause irritation on sensitive areas. The effect of this is not long lasting.
Vitamin A derivatives are also found in the form of tablets and ointments to help cure psoriasis, but it should not be recommended to women, who are pregnant or who may become pregnant.
Tar Compounds are mainly used for the treatment of scalp psoriasis.
Light therapy is available only at the hospital clinics. It is apparent that shining of ultraviolet B on the affected area helps cure psoriasis (not 100%).
If you have moderate psoriatic symptoms, Psoralen and ultraviolet A light treatment (PUVA) helps reduce your symptoms.
If these treatments do not help in reducing symptoms, medicines that suppress immune system are used. These are available in tablets (methotrexate, cyclosporin, etc) or injections (efalizumab, infliximab, etc).
At the same time, it is necessary to know that nothing can cure psoriasis completely, but it can be controlled.
