Picato is indicated for the cutaneous treatment of non-hyperkeratotic, non-hypertrophic actinic keratosis in adults. The mechanism of action of ingenol mebutate for use in actinic keratosis remains to be fully characterised. Results from two clinical studies on biological effects of ingenol mebutate have shown that topical administration induced epidermal necrosis and a profound inflammatory response in both epidermis and the upper dermis of the treated skin, dominated by infiltrating T cells, neutrophils and macrophages.

Metronidazole is an anti-infectious drug belonging to the pharmacotherapeutic group of nitroimidazole derivatives, which have effect mainly on strict anaerobes. This effect is probably caused by interaction with DNS and different metabolites.

Tirbanibulin disrupts microtubules by direct binding to tubulin, which induces cell cycle arrest and apoptotic death of proliferating cells, and is associated with disruption of Src tyrosine kinase signalling.
