What is psoralen PUVA used for?

PUVA is a combination of psoralen (P) and long-wave ultraviolet radiation (UVA) that is used to treat psoriasis and some other several severe skin conditions. Psoralen is a drug taken by mouth that makes the skin disease more sensitive to ultraviolet light.

How is psoralen administered?

PUVA is a combination treatment consisting of taking a drug PSORALEN (P) and then exposing the skin to long-wave ultra- violet light (UVA) – hence the term PUVA. Psoralen is a drug that makes the skin temporarily sensitive to UVA. It may be taken as pills by mouth or by applying it directly to the skin.

What is Photochemotherapy used for?

What is PUVA? PUVA or photochemotherapy is a type of ultraviolet radiation treatment (phototherapy) used for severe skin diseases. PUVA is a combination treatment which consists of Psoralens (P) and then exposing the skin to UVA (long wave ultraviolet radiation).

Is methoxsalen carcinogenic?

Methoxsalen plus UVA radiation is carcinogenic to humans (Group 1).

How does psoralen treat skin conditions?

Psoralens boost the amount of ultraviolet light your skin absorbs. This lets the light into your skin. The ultraviolet radiation helps treat severe skin diseases like psoriasis, vitiligo, polymorphic light eruption, and cutaneous T-cell lymphoma, a type of cancer.

What are the side effects of oral psoralen in phototherapy?

Side effects include phototoxicity, nausea, skin dryness, sunburn, hyperpigmentation (skin darkening), itching, and increased risk of skin cancer. PUVA therapy is not considered safe for children and pregnant women due to systemic use of the chemical psoralen.

What foods contain psoralens?

Psoralens are natural products found in plants such as limes and lemons, celery, bergamot, parsley, figs, and cloves.

Is Photochemotherapy chemotherapy?

11.10 UVB phototherapy, psoralen plus UVA photochemotherapy (PUVA) For treating psoriasis, UVB phototherapy and PUVA are effective treatments that permit rapid control of the disease, but their side effects are similar to those of radiotherapy and chemotherapy.

What does PUVA stand for?

PUVA is the acronym for Psoralen + ultraviolet light A. PUVA is a type of phototherapy used in treatment of psoriasis and other skin conditions. Treatment requires the patient to ingest a light-sensitizing medication called psoralen before being exposed to UVA rays.

What is Methoxsalen used to treat?

Methoxsalen belongs to the group of medicines called psoralens. It is used along with ultraviolet light (found in sunlight and some special lamps) in a treatment called PUVA to treat vitiligo, a disease in which skin color is lost, and psoriasis, a skin condition associated with red and scaly patches.

Where is methoxsalen from?

Methoxsalen is a naturally occurring photoactive chemical found in the seeds of the Ammi majus (Umbelliferae) plant and in the roots of Heraclem candicans. It belongs to a group of compounds known as psoralens, or furocoumarins. Methoxsalen lotion is used for treating vitiligo (leucoderma).

Is PUVA chemotherapy?

PUVA Therapy Overview PUVA refers to the interaction of long wavelength ultraviolet light (320-400 nm) with a pharmaceutical molecule of plant origin, psoralen, producing a type of “photodynamic chemotherapy.” PUVA is useful in treating a number of human diseases.

How is PUVA therapy performed?

In the most common form of PUVA therapy, the patient is administered Oxsoralen-Ultra ® (8-methoxypsoralen) by mouth. The dosage of the drug is determined by the weight of the patient. About 45 to 60 minutes later, skin is exposed to the long wave ultraviolet radiation for a length of time determined by the patient’s skin pigmentation.

What are the side effects of PUVA and Oxsoralen?

PUVA will cause photo- aging (dry and wrinkled with pigment alterations called lentigenes) that is unavoidable. If not appropriately monitored, PUVA can produce severe ultraviolet light burns. Occasionally, Oxsoralen can cause nausea so susceptible patients take the drug with food.
