DefinitionThis section has been translated automatically.

Synthetic peptide hormone illegally distributed as a tanning agent. Melanotan I and II are the synthetic variant of the alpha-melanocyte stimulating hormone (alpha-MSH), which activates the epidermal melanin production. Melanotan (afamelanotide) was developed as a drug for the treatment of Protophorphyria erythropoetica and is used as a "designer drug" for body tanning.

Pharmacodynamics (Effect)This section has been translated automatically.

Melanotan I binds to the melanocortin 1 receptor (MC1R) and its stimulation causes an activation of the melanocytes. Melanotan II binds to the melanocortin 2-3-4 receptors (MC2-4R). Its effect on skin tanning is more intensive than that of Melanotan I. In addition, these melanocortin receptors reduce appetite, improve erection and increase libido (Barbie drug).

Dosage and method of useThis section has been translated automatically.

The preparation is an approved drug. Before and during phases of strong sun exposure, e.g. from spring to autumn, the patient is injected under the skin with an implant (16mg) every two months. The number of implants per year depends on how much protection against sunlight is required. 3 implants per year are recommended; the maximum number is 4.

Undesirable effectsThis section has been translated automatically.

Growth activation of melanocytic nevi. Headaches, inflammatory reactions at the implant site. Cases of de novo malignant melanoma are questionable.
