The medical uses about Methoxsalen


Methoxsalen  is used along with controlled ultraviolet light (UVA) to cause a return in skin color in patients with a certain skin condition (vitiligo). Methoxsalen works by making the skin more sensitive to UVA light. This combination helps to increase the number of pigment-producing cells (melanocytes) in the skin.
Methoxsalen  is a drug used to treat psoriasis, eczema, vitiligo, and some cutaneous Lymphomas in conjunction with exposing the skin to sunlight. Methoxsalen is extracted from Ammi majus, a plant of the family Apiaceae. Methoxsalen modifies the way skin cells receive the UVA radiation, allegedly clearing up the disease. The dosage comes in 10 mg tablets, which are taken in the amount of 30 mg 75 minutes before a PUVA (psoralen + UVA) light treatment. The substance is also present in other Apiaceae as well as Rutaceae, for example bergamot oil which is used in many perfumes and aromatherapy oils.
Methoxsalen  is a naturally occurring substance that is reactive to light. It works by enhancing the body's sensitivity to ultraviolet light A (UVA). Methoxsalen is used in combination with UVA light therapy to treat severe psoriasis. Methoxsalen is usually given after other psoriasis medications have been tried without successful treatment of symptoms.
However, Patients with high blood pressure or a history of liver problems are at risk for inflammation and irreparable damage to both liver and skin. The eyes must be protected from UVA radiation. Side effects include nausea, headaches, dizziness, and in rare cases insomnia. Methoxsalen has also been classified as an IARC Group 1 carcinogen (known to cause cancer) but is only cancerous when combined with Ultra Violet-A radiation.
