Zmiany hiperpigmentacyjne jako niepożądany efekt działania wybranych leków
Hyperpigmentation as a side effect of the selected pharmaceuticals activity

Summary/Abstract: The work shows the mechanism of creating pigmentation i.e. melanin as well as its transformation which due to external or internal factors could predispose to skin hyperpigmentation. The changes in the skin color that are the side effect of drugs are 10–20% of all hyperpigmentations. It is a result of hypersynthesis of melanin, increased formation of lipofuscin, cumulating pharmacological compounds and often it can outgoing inflammatory condition. UV radiation has been found an important concomitant factor in causing this type of skin change. There is a large group of pharmaceutical drugs and botanical extracts that could sensitize skin to UV radiation. This includes mainly antibiotics, antiarrhythmic drugs, hormonal drugs, cytostatic as well as supplements containing St John’s wort, celery, Angelica archangelica or rue.
